Description

Stepless speed regulator based on differential transmission/power confluence mechanism and energy-saving system thereof

Technical Field

The invention relates to the technical field of stepless speed regulation and power load adaptation of stepless speed regulators, power dividing/converging devices, two-way/multistage power allocation devices, energy recovery devices and the like in rotary power and load systems thereof (such as fans, pumps, various transportation tools, various mechanical equipment and the like), in particular to a stepless speed regulator based on a differential transmission/power converging mechanism and an energy-saving system thereof, wherein the power regulating/speed regulator integrates part or all of the functions of stepless speed regulation, torque conversion, energy recovery, power mixing, distributed power allocation, power stepless allocation and the like.

Background

In more than ten years, the rapidly developed permanent magnet coupling speed regulator is gradually accepted by experts and markets in the field of centrifugal load speed regulation, energy conservation and emission reduction, but has obvious defects and shortcomings. Since 2009, the inventor of the invention successively obtains authorization from more than ten inventions in the aspect of permanent magnet coupling speed regulators, establishes a factory with self-funding, forms mass production, and is widely applied and commented on the aspects of energy conservation and emission reduction of industrial centrifugal load systems (fans, water pumps and the like), so that the energy-saving technical level is greatly improved, but the inventor gradually realizes that the permanent magnet coupling speed regulators have many advantages in the popularization process, but also has the following defects which are difficult to overcome: firstly, as the driving disc and the driven disc are in an air gap coupling cantilever beam structure and are limited by the design of the axial installation size of the equipment, severe vibration and noise are inevitably generated under the working conditions of high power or/and high rotating speed, so that the reliability of the system is poor; secondly, the system efficiency is low, especially under the working conditions of low rated rotating speed, high power and more speed reduction, the energy in direct proportion to the percentage value of the speed reduction can be changed into a large amount of heat to be consumed on a metal conductor disc, the average actual working total useful efficiency of the power load system is generally lower than 60 percent, especially the high-power model, because a cooling device is added in the system, the cost is increased, and the reliability is greatly reduced; thirdly, only speed reduction adjustment is performed, and speed increase adjustment cannot be performed; fourthly, the speed regulation precision is lower; fifthly, the driving (power) shaft and the driven (load) shaft do not have a torque conversion or self-locking function, and the application is limited greatly.

The high-voltage high-power motor frequency converter is also applied to the energy-saving and emission-reducing field of a centrifugal load system, but has the disadvantages of large occupied space, poor reliability and large self energy consumption due to high requirement on the operating environment (constant temperature and humidity); due to the restriction of the working efficiency characteristics, the average actual working total useful efficiency of most frequency band power load systems is obviously reduced compared with the rated efficiency, and is generally lower than 60%; the frequency converter can also generate serious power harmonic pollution, and the high-voltage frequency converter has the defects of high price, special maintenance, huge operation cost and the like, and is widely subjected to scaling.

The hydraulic coupling speed regulators are also widely arranged in adjusting type centrifugal load and non-centrifugal load systems (such as a fan, a water pump, a ball mill, a feeder, a belt conveyor, a heading machine, a drilling machine, a lifter, an air compressor and the like), and the technical lag is more obvious because the average practical working total useful efficiency of the power load system is lower compared with the average practical working total useful efficiency, the speed regulation range is smaller, the hydraulic medium consumption is large, the environment is polluted and the like.

For the energy-saving technology of the traditional speed regulator, on one hand, the energy-saving technology is only suitable for a 'big horse pulls a trolley' system, which is not beneficial to improving the system efficiency and causing resource allocation waste; on the other hand, for a high-power system, in the process of load deceleration adjustment, the power consumed by the load can only be reduced, the output efficiency of the power system cannot be improved, the working efficiency of the power system is greatly reduced, the energy consumption and heat generation of the system are serious, the heat is difficult to recycle, a cooling device is required to be arranged in the system, and the reliability of the system is also obviously reduced while the cost input is greatly increased. In other words, for the current large-scale power load system, especially for the centrifugal equipment such as the large-scale fan water pump and the like, even if energy-saving equipment such as a frequency converter, a permanent magnet speed regulator, a hydraulic coupler and the like is installed, the average actual working total useful efficiency of the power load system generally does not exceed 65 percent or even is lower, and the waste is huge. In addition, the common power and load system also has the problem of matching power with load, which also causes serious waste of energy or power. Therefore, in order to solve the long-standing problem of 'old and difficult' in the technical field of energy conservation and emission reduction, the traditional speed regulation/speed change products and the energy conservation and emission reduction technology thereof need to be innovated urgently, the existing 'pain spots' are comprehensively applied, and the development and production of a new generation of stepless speed regulation based on a differential transmission/power confluence mechanism and a stepless speed regulator based on the differential transmission/power confluence mechanism and an energy-saving system thereof are necessary.

On one hand, the invention not only comprises various technical schemes with different configurations which take 'full power, enough low consumption and more recovery' as power configuration concepts; on the other hand, the invention also comprises more advanced technical schemes with various different configurations which are constructed by taking a further innovative energy-saving concept of 'measuring force, required amount and no waste' as a functional target, so as to abandon the traditional power configuration scheme that a big horse pulls a trolley 'is required to be followed when cold starting is required, namely' the rated power of a power source is more than or equal to the rated power of a load (1+ the power redundancy coefficient of power required by the cold starting of a system is 15-20%), and the rated power of a speed-regulating energy-saving device is more than or equal to the rated power of the load ', and establish an innovative energy-saving power load configuration scheme, namely' the rated power of a main power source + the rated power of a power regulating/speed-regulating motor is more than or equal to the rated power; in addition, the invention also comprises that at least two power, namely a hybrid/distributed power configuration scheme is adopted according to the actual requirement or in order to solve the problem that the super-power equipment is difficult to operate, so that the problem of driving of super-load is solved, or the problem of large under-load operation energy consumption of a large horse-drawn trolley under the condition of changing load at any time is solved, and particularly the integral operation efficiency of the system is seriously reduced due to the speed reduction operation of large or super-large power equipment. In conclusion, the invention develops a new and perfect technical scheme for energy conservation and emission reduction, and becomes possible to construct a super energy-saving intelligent power load system.

The more intelligent, more functional and innovative performance is shown in the following aspects: firstly, the main power source does not work firstly in the starting process, and the power regulating/speed regulating motor works firstly to realize the load soft starting function; secondly, in the normal working process of the power load system, the output rotating speed and the torque of the power regulating/speed regulating motor are controlled, and the purpose of regulating the rotating speed and the power of the load is achieved through the power converging mechanism, so that the problems of system efficiency reduction and serious energy consumption caused by speed reduction generated by applying the traditional energy-saving technology in the constant rotating speed power system are solved; thirdly, particularly in a variable-frequency energy-saving system of a high-voltage high-power load, because the power regulating/speed regulating motor can select a voltage grade different from that of the main power source and a smaller power model, the high-reliability and low-cost medium-voltage and low-voltage power regulating/speed regulating motor and a frequency converter thereof are more convenient to adopt, the energy-saving transformation of the traditional high-voltage high-power motor system is more easily realized at low cost, and the resource allocation of the power system of the large-scale load is more reasonably and intensively constructed; fourthly, distributed hybrid power can be adopted to replace a single main power source to provide power for the large load, so that the power configuration scheme of the large load is more diversified, and the reasonability, the safety and the reliability of power supply are improved; the power configuration scheme of the main power source and the power regulating/speed regulating motor eliminates the defect, so that the high-efficiency work of power equipment under all-weather working conditions becomes possible; and sixthly, in the fields of industrial and agricultural production and life of society, the energy-saving field of large and medium-sized centrifugal equipment (such as fans, pumps and the like) is provided, the technical scheme of the invention can improve the total energy-saving efficiency of the system by at least more than 30 percent, and has wide application space and market prospect. It is easy to see that the speed regulator based on the power converging mechanism of the planetary gear set provides important technical support in the aspect of energy conservation for constructing a super energy-saving power load system according to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation theorem. It should be noted that the power types of the main power source described below are various, and any rotary power source may be used, such as an electric motor, an internal combustion engine, a steam turbine, a water turbine, etc., and certainly, in some application conditions, the main power source may also be the same type as the power adjusting/speed regulating motor, so that the type selection results in more convenient maintenance and emergency replacement of the equipment, or, by operating the control switch device, the time-sharing/combination between the main power source power adjusting/speed regulating motor and the power adjusting/speed regulating motor is controlled by the shared control driver/frequency converter, thereby facilitating establishment of the combined control and control switching function suitable for the special requirements.

In the application scene of power load equipment in the fields of social life and industrial and agricultural production, a specific speed regulation range can be designed and determined according to different working conditions and process requirements, and the common configuration scheme of a main power source and a power regulation/speed regulation motor and a working module/mode list thereof are as follows for the system to call and operate in real time:

in order to meet the requirement that the rated power of the main power source plus the rated power of the power regulating/speed regulating motor is more than or equal to the rated power of the load

The rated power of the main power source is more than or equal to K% of the rated shaft power of the load,

wherein K < 50 to 100 is optional, and generally 60 to 75 segments are preferred;

correspondingly, the rated power of the power regulating/speed regulating motor is more than or equal to (1-K) load rated shaft power:

soft start & stepless speed/power regulation range 1: from 0% to K%;

stepless speed increase/power regulation range 2: from K% to 100%;

stepless speed reduction/power regulation range 3: from K% to 0%.

Firstly, a soft start module, wherein a speed regulator works in a state of soft start and stepless regulation range 1, before a main power source is put into operation, a power regulation/speed regulation motor is started to work, so that the power regulation/speed regulation motor outputs positive torque from small to large to drive a load to start slowly, then the main power source is started again, the rotating speed of the load is changed from low to high, the load is started smoothly, the load is transited to normal operation, and the extremely many times of starting power required by rapid start of the load can be greatly reduced; especially for high-speed large-inertia high-power load systems, the rapid start often fails, even burns power equipment, so that the soft start module is very necessary.

And secondly, a heat engine/light load module, wherein the speed regulator works in a 'rear soft start' state, a power load system sometimes needs a load device to be in a low-rotating-speed (light-load) heat engine idle speed operation state, namely the main power source is not started, the load is in a separation/no-load/light load state, the power regulation/speed regulation motor continuously works and outputs positive torque, and the load is driven to perform idle speed operation at a load rotating speed which is less than or equal to the rated power of the power regulation/speed regulation motor.

And a basic operation/direct drive operation module, generally speaking, in order to comprehensively consider the two factors of small system construction investment and good energy-saving effect, the rated power and the rotating speed of the main power source are determined according to the most basic load shaft power and rotating speed in the most common working condition/process of the load, at this time, the power regulation/speed regulation motor is in a static state or the transmission shaft thereof is in a braking state of 0 rotating speed and large torque, the regulation power is not output, the power regulation/speed regulation motor only depends on the main power source to work, the rated power and the rotating speed are output, and the load is maintained to work in the most basic (or minimum) and most common working condition/process rated power and rotating speed states.

And fourthly, a stepless speed increasing/power regulating running mode, wherein only the normal rated power of the main power source can not meet the requirement of increasing the load power/rotating speed under the working condition, the power regulating/speed regulating motor is arranged in the working state of the motor, namely, the power regulating/speed regulating motor is put into work and outputs positive torque (torque in the same direction as the positive rotating speed of the load), the output power/torque of the power regulating/speed regulating motor is regulated in real time according to the requirement of the working condition, and the power converging of the stepless speed regulators based on the differential transmission/power converging mechanism is utilized to drive the load equipment to work together until the rated power/torque of the main power source and the rated power/torque of the power regulating/speed regulating motor are more than or equal to the rated shaft. The system works in a 'stepless speed-increasing adjusting range 2' state, the main power source runs at rated power and rotating speed, the power adjusting/speed adjusting motor is put into operation at the power and torque/rotating speed which are controlled and adjusted to be set, the sum of the power and the torque/rotating speed is equal to the power of a load shaft under real-time working conditions, and the power adjusting/speed adjusting motor is controlled to output adaptive power and rotating speed according to the working condition process requirements, so that the purpose of driving the load power, which is required and is not wasted, is achieved. At the moment, the main power source and the power regulating/speed regulating motor respectively drive the planetary gear to rotate and revolve through the power input end/shaft and the power regulating end/shaft of the speed regulator, the rotation torque and the revolution torque of the planetary gear are superposed on the power output end/shaft of the speed regulator in the same direction, namely the output power of the main power source and the output power of the power regulating/speed regulating motor are converged to the output end/shaft of the speed regulator, so that the work doing operation of two or more (multistage series) distributed power resultant force driving loads can be realized.

The speed reduction/emergency regulation operation mode-non-power recovery speed reduction operation mode, generally speaking, there are power braking and speed reduction losses under this mode, the normal but not limited to emergency operation, the speed regulator works under the "stepless speed reduction regulation range 3" state, the main power source operates at the rated speed, when the load speed needs to be reduced to operate, or meets the abnormal emergency load speed requirement under the special working condition process condition, the power regulation/speed regulation motor is started to set at the negative torque (the torque opposite to the positive rotation working direction of the power regulation/speed regulation motor driving load), that is, while the main power source operates at the rated speed, the power regulation/speed regulation motor is controlled to operate with the reverse braking power and the torque/speed, the power difference between the two is equal to the load shaft power under the emergency real-time working condition process condition, the power regulating/speed regulating motor is controlled to output adaptive braking power according to the requirement, so that the load is accelerated to run, and the energy-saving effect of load acceleration is achieved. At the moment, the main power source and the power adjusting/speed regulating motor respectively drive the planetary gear to rotate and revolve in opposite directions through the power input end/shaft and the power adjusting end/shaft of the speed regulator, the rotation torque and the revolution torque of the planetary gear are opposite in direction, and the braking torque in the opposite direction impacts and resists to the power output end/shaft of the speed regulator, namely the difference of the output power of the main power source and the output power of the power adjusting/speed regulating motor is converged to the output end/shaft of the speed regulator, so as to meet the requirement of emergency speed reduction operation of loads. The module is only arranged for meeting the current occasional need of the special working condition process. The reason is that under the working module, in order to meet the energy saving of the system under the speed reducing working condition of flow rate and pressure regulation and reduction, especially for centrifugal load, the real-time shaft power of the load is in direct proportion to the cube of the rotating speed, and even if the module consumes a little braking power of the power regulation/speed regulation motor, the overall energy saving effect is good. The running frequency of the module is reduced, and the solution is to reduce the rated power configuration of the main power source and increase the rated power configuration of the power regulating/speed regulating motor, so that the system cost is higher, but the more energy-saving speed regulating range of the normal stepless speed increasing regulating range 2 is larger. According to the equipment configuration principle disclosed by the invention, the factors of favorable energy conservation and low cost under various working conditions and process conditions are considered comprehensively so as to construct a more reasonable stepless speed regulator.

Sixthly, the stepless speed reduction/load power regulation is carried out, namely, the power regulation/speed regulation motor works in a generator state to form a power regulation generator, the main power source is used for carrying out power regulation through a stepless speed regulator based on a differential transmission/power convergence mechanism, part of the output power or torque of the main power source drives a load device to work at a lower running speed through a power output end of the stepless speed regulator based on the differential transmission/power convergence mechanism, the other part of the output power or torque of the main power source is distributed to the power regulation generator through a power regulation end of the stepless speed regulator based on the differential transmission/power convergence mechanism to drive and generate power, the power output is fed back to the electrodynamic equipment through a corresponding loop of the controller for use, or the electric energy is provided for an internal/external power grid, or the electric power is supplied to an electric storage device or other electric loads.

The scheme is based on and utilizes the working mechanism of a planetary gear differential transmission mechanism and a power converging/diverging transmission mechanism, and deeply excavates the correlation interaction relationship of differential speed and power converging/diverging between a left half shaft gear, a right half shaft gear and a planet carrier (a planetary gear differential shell) of the differential transmission mechanism by using the minimum energy consumption principle, the lever principle, the gear transmission principle, the energy conservation principle and the regulation type load speed regulation energy-saving principle to realize the function of energy three-dimensional adaptation, distribution or mutual control, and endows the new design concept and function of the planet carrier, the left half shaft and the right half shaft of the power diverging/differential transmission mechanism, thereby constructing the stepless speed regulator based on the differential transmission/power converging mechanism with different purposes and functions. In the scheme, the planet carrier, the left half shaft and the right half shaft can be respectively used as a power input end, a power adjusting end or a power dividing/allocating/adapting end, and the difference is that energy transmission paths are different, and an allocated torque transmission ratio and a rotating speed ratio between input and output are different. That is, one of the two left and right axle shafts serves as an output/shaft of a continuously variable speed governor based on a differential transmission/power combining mechanism; one of the other half-shaft and the planet carrier serves as the main power input/shaft, the remaining one serves as the power regulating end/shaft and is coupled to the rotor/rotor shaft of a power regulating/governor motor (meaning a motor with real-time on-line bi-directionally controllable motor/generator functionality). The stepless speed regulator based on the differential transmission/power converging mechanism can be used in a single stage, and can also be arranged in a multi-stage series/parallel connection mode, so that more power sources can be put into the stepless speed regulator, and the stepless speed regulator can be assembled into a more flexible, various and powerful working mode.

Detailed Description

Example 1

As shown in fig. 1 and 2, the stepless speed regulator based on the differential transmission/power confluence mechanism is an embedded stepless speed regulator based on an asymmetric axial cylindrical planetary gear differential transmission/power confluence mechanism. An asymmetric axial cylindrical planetary gear differential transmission/power confluence mechanism (the differential transmission/power confluence mechanism is in some common technical fields such as the field of automobiles, or is called as a differential mechanism, in the field of transmission technology or is called as a power divider, a power confluence mechanism, a power division mechanism and the like, which have different or different structures but have different working mechanisms in different application fields) is integrally embedded in a hollow rotor of a power regulation/speed regulation motor, and mainly comprises four axial cylindrical planetary gears (107 and 116), power confluence mechanism components (101, 102, 103, 105, 106, 107 and 116), stator components (120, 121, 122, 123, 124 and 133) and permanent magnet hollow rotor components (130, 131, 132, 113 and 114) of the permanent magnet power regulation/speed regulation motor, speed regulator accessories (126, 131, 132, 113 and 114), and speed regulator accessories (126 and 116), 110. 115, 125 and 138), an adaptive power regulating/governor motor control drive/vector control type frequency converter and its motor speed encoder (not shown). Wherein, the axial cylindrical planetary gear differential transmission/power combiner component comprises an upper cylindrical planetary gear (107), a lower cylindrical planetary gear (107), a left cylindrical planetary gear (116), a right cylindrical planetary gear (107), a lower cylindrical planetary gear (105), a straight pin type planetary gear shaft (105), a planetary gear carrier (101), a left half shaft gear/cylindrical internal tooth ring gear (102) and a right half shaft gear/cylindrical external tooth sun gear (103), the four straight pin type planetary gear shafts (105) are all arranged in parallel with the central axes of the left half shaft (109) and the right half shaft (129), each cylindrical planetary gear (107 or 116) is respectively meshed with the right half shaft cylindrical external tooth sun gear (103) and the left half shaft cylindrical internal tooth ring gear (102), the left half shaft (102) is used as the power adjusting end of the stepless speed regulator and is connected with the rotor (130) body into an integral structure, the right half shaft (129) is used as the power output end/shaft of, the permanent-magnet type hollow rotor shaft is also used as a right half rotor shaft (129), a right rotor end cover (114) and an isolation/support bearing (115 and 125) of a stator end cover (124) are arranged to be a right half rotor shaft (129) of a shaft system of a hollow rotor of a power regulation/speed regulation motor, a cylindrical planet carrier (101) is used as a power input end of a main power source and is in adaptive connection with a left half rotor shaft (109) by using a shaft key (136), an isolation/support bearing (110 and 126) of a rotor end cover (113) and a stator end cover (133) which are adaptive on the left side is arranged to be a left half rotor shaft (109) of a shaft system of a permanent-magnet type hollow rotor (130) of the power regulation/speed regulation motor, and extends out of a left rotor end cover (113) and a stator end cover (133) to be a shaft extension (139) of a power input shaft (109) of a stepless speed regulator, stator core (121), stator field winding (122), rotor permanent magnet assembly (132), bolt fastener (138), etc. The power regulation/speed regulation motor control driver/vector control type frequency converter has wide market application, can control the power regulation/speed regulation motor to regulate the rotating speed at will, can set the power to output at constant rotating speed or constant torque, can set the rotating speed to output at variable power or variable torque, and can work under various flexible, convenient and practical functional modules/modes such as 'zero rotating speed + braking torque'.

The working mechanism is as follows: neglecting the internal friction torque (the same below), a planet gear carrier (101) is used as a power input end/shaft, a left half shaft gear ring (102) is used as a power adjusting end, a right half shaft sun gear (103) is used as a power output end/shaft, and according to the minimum energy consumption principle, the lever principle, the gear transmission principle and the energy conservation theorem, four planet gears are equivalent to four equal-arm levers to simultaneously act and construct a group of asymmetric planet gear transmission mechanisms together with the left half shaft gear and the right half shaft gear. It is easy to see that: the main power source rotates clockwise and the rotating speed is constant, the left half-axle power input ends/shafts (139, 109) drive the planet gear carrier (101) to rotate clockwise, the planet gear carrier (101) drives four planet gears (107 and 116) to respectively revolve around the sun gear (103) clockwise on one hand and respectively rotate anticlockwise on the other hand, and simultaneously drives the left half-axle gear/cylindrical internal tooth ring gear (102) and the right half-axle cylindrical gear/cylindrical external tooth sun gear (103) to respectively rotate clockwise;

if the power adjusting/speed regulating motor is controlled to enable the hollow rotor (130) to apply positive torque to the left half-shaft gear ring (102), the torque can accelerate the anticlockwise rotation speed of the four planetary gears and simultaneously drive the right half-shaft sun gear (103) to increase clockwise torque, so that the clockwise rotation speed of the right half-shaft sun gear (103) is accelerated, power confluence of the planetary gear carrier (101) and the left half-shaft gear ring (102) is formed, the purpose of accelerating the power output end/shaft (129) of the right half-shaft sun gear (103) is achieved, and the operation is in an acceleration adjusting operation mode;

if the power adjusting/speed regulating motor is controlled to enable the hollow rotor (130) to apply reverse torque to the left half axle gear ring (102), or enable the left half axle gear ring (102) to rotate in the reverse direction, the reverse torque can enable the four planetary gears (107 and 116) to reduce the anticlockwise rotation speed or offset the rotation torque, further enable the right half axle sun gear (103) to brake or reduce the clockwise rotation torque, namely forming brake torque, the purpose of stepless speed reduction of the power output end/shaft (129) of the right half axle sun gear (103) is achieved, and the operation is equivalent to a speed reduction/emergency adjusting operation mode.

The embodiment is a device which combines the power of a power adjusting end/shaft and the power input end/shaft into power which is added/subtracted to be converged to a power output end/shaft, so that the total output power of a main power source and a power adjusting/speed regulating motor is converged to the output end/shaft of a speed regulator, and the aim of carrying out real-time stepless speed regulation on a load is fulfilled. The power regulation/speed regulation motor control driver/vector control type frequency converter has the following five working modules/modes for calling: the method comprises a soft start mode, a heat engine/light load mode, a basic operation mode, a stepless speed increasing operation mode, a speed reducing/emergency adjusting operation mode.

It is easy to see that the power input end/shaft, the power adjusting end/shaft and the power output end/shaft can be regarded as causal adjusting relations with each other, i.e. adjusting one or/and two factor variables, even the third factor variable will change accordingly, for example, for a centrifugal load system, when the rotating speed changes, the load power will change in 3-power exponential manner, the power will be significantly reduced, which is the most important mechanism of industrial energy saving and emission reduction, after the energy transfer relations of the three are balanced, the desired and adapted working rotating speed, torque or/and shaft power of the power input end/shaft can be obtained, so that the system can respond in real time and reach the most energy-saving working state under different modes, so as to meet different working condition process designs, working module/mode control flows and actual emergency requirements, the optimal practical effect of the invention is achieved. The conclusion of this mechanism of operation also applies to the following examples.

The differential transmission/power confluence mechanism assembly is integrally embedded in a hollow rotor of the power regulating/speed regulating motor and mainly comprises radial conical planetary gears (207 and 216), differential transmission/power confluence mechanism assemblies (201, 202, 203, 205, 206, 207 and 216), stators (220, 221, 222, 223, 224 and 233) and hollow rotors (230, 231, 232, 213 and 214) of the power regulating/speed regulating motor, other accessories (226, 210, 215, 225 and 238) of a stepless speed regulator based on the differential transmission/power confluence mechanism, a motor/generator duplex controller and a state sensor (not shown in the structural schematic diagram of the embodiment). The radial conical planetary gear differential transmission/power confluence mechanism component consists of an upper conical planetary gear (207, 216), a lower conical planetary gear (207, 216), a straight planetary gear shaft (205), a planetary gear carrier (201), a left half shaft (209, 229) and a right half shaft (202, 203) which are same in size and number of teeth and are symmetrically arranged, the planetary gear carrier (201) is radially provided with the straight planetary gear shaft (205), the center line of the straight planetary gear shaft (205) is vertically arranged with the central axis of the left half shaft (209) and the right half shaft (229), the upper conical planetary gear (207), the lower conical planetary gear (216) are respectively meshed with the symmetrical left half shaft and right half shaft circular bevel gears (202, 203), the right half shaft (229) is used as a power output end/shaft, and a shafting system of a hollow rotor of a power regulation/speed regulation motor is arranged through isolation/support bearings (215 and 225) of a right side rotor end cover (214) and a stator end cover (224) which are matched at A right half rotor shaft (229) extends out of the right rotor end cover (214) and the stator end cover (224) to form a power output shaft (229) shaft extension (249) of a stepless speed regulator based on a differential transmission/power convergence mechanism, a left half shaft (209) is used as a power input end/shaft, a shaft system left half rotor shaft (209) of a hollow rotor of a power regulation/speed regulation motor is arranged through isolation/support bearings (210, 226) of a rotor end cover (213) and a stator end cover (233) which are matched on the left side, a shaft extension (239) of a power input shaft (109) of the stepless speed regulator based on the differential transmission/power convergence mechanism is arranged out of the left rotor end cover (213) and the stator end cover (233) of the power regulation/speed regulation motor, a planet carrier (201) is used as a power regulation end and is arranged into an integral structure or is in transmission connection with a rotor core (231) of a hollow rotor body (230) of the, other accessories of the stepless speed regulator based on the differential transmission/power confluence mechanism further comprise a stator shell/body (223), a stator iron core (221), a stator excitation winding (222), a rotor permanent magnet assembly (232), a bolt fastener (238) and the like.

The working mechanism is illustrated as follows: the planet carrier is used as a power adjusting end (omega)_{Tune 1}、M_{Tune 1}、P_{Tune 1}) With the left half-shaft as the power input/shaft (ω)_{1 to}、M_{1 to}、P_{1 to}) The right half shaft is used as a power output end/shaft (omega)_{Go out 1}、M_{Go out 1}、P_{Go out 1}) According to the principle of minimum energy consumption, the principle of levers, the principle of gear transmission and the theorem of conservation of energy, the planetary gear is equivalent to an equiarm lever becauseThe left and right semi-axis gears are symmetrical and have equal radius, and the differential device divides the torque or power of the power adjusting end/axis into two parts, just like a differential in an automobile, and when the planetary gear revolves and rotates:

in one aspect, the formula of angular velocity ω_{1 to}+ω_{Go out 1}＝2ω_{Tune 1}Torque distribution equation M_{1 to}＝M_{Go out 1}＝(1/2)*M_{Tune 1}And conservation of energy power formula P_{Tune 1}＝P_{1 to}+P_{Go out 1}I.e. P_{Go out 1}＝P_{Tune 1}-P_{1 to}When the rotating speed of the power input end/shaft is constant, the rotating direction and the rotating speed of the power adjusting end/shaft are adjusted to enable the power output end/shaft to obtain the torque, power or load rotating speed which is wanted to be achieved (in the formula, the power adjusting/speed adjusting motor or/and the main power source is allowed to rotate reversely or/and work reversely, and negative torque, negative angular speed or/and negative power are correspondingly presented, the same is applied below); on the other hand, the system allows real-time setting or by adjusting the magnitude of the positive and negative torque, power or/and rotating speed of the power adjusting end/shaft, stepless adjustable power, torque or/and load rotating speed can be obtained at the power output end/shaft in real time, namely, the reverse rotation or/and reverse torque is allowed in the formula, and corresponds to the negative torque, the negative angular speed or/and the negative power; in yet another aspect, the system also allows the power adjustment end/shaft to be set in a locked state (where the power consumption of the power adjustment end/shaft is 0), i.e., ω_{1 to}+ω_{Go out 1}＝2ω_{Tune 1}、ω_{Tune 1}0, so ω_{Go out 1}＝-ω_{1 to}；P_{1 to}+P_{Go out 1}＝P_{Tune 1}、P_{Tune 1}If is 0, P_{Go out 1}＝-P_{1 to}At this time, the rotating speed of the power input end is opposite to the rotating direction of the load, and the rotating speed of the load is equal to the rotating speed of the main power source.

It can be seen from the above that the power input end/shaft, the power adjusting end/shaft and the power output end/shaft are mutually adjusting variables, one or/and two of the variables, even the third variable, is changed accordingly (for example, for a centrifugal load system, when the rotating speed changes, the load power of the centrifugal load system changes in a 3-power index manner, etc.), and after the above relational expression is balanced, the desired and adaptive working rotating speed, torque or/and shaft power of the power transmission end/shaft can be obtained, so that the above-mentioned working mode and control module are constructed, allocated or combined to make the system randomly respond and achieve a good working state, so as to meet different working condition designs, working mode control flows and actual application requirements.
