Description
Technical Field
The present invention relates to mechanical drive mechanisms, and more particularly to a mechanism comprising a set of parallel axis rotors of unequal spacing that simultaneously drive the synchronous rotation of the rotors without the need for additional motion transfer components between the independent rotors.
Background
The power transmission is one of the most basic features of a mechanical system, and the working motion of a mother machine is usually driven by a rotary power source. The most common mechanical systems typically have a rotary power source that drives a set of components powered by the power source. The parts for transmitting power comprise gears, pinions, pulleys, belts, chains and the like which are mutually connected to complete the transmission of power to the actuating mechanism. With complex mechanical systems, the energy transfer from a single input source to the motion of multiple components is very costly to transmit, i.e. for a certain amount of rotational drive energy, the output energy is significantly lost due to the motion of the transmission components pushed by part of the energy during operation. Furthermore, the more complex a mechanical system component, the greater the potential risk of wear and failure, which undoubtedly increases the service and maintenance costs.
A synchronous drive mechanism with parallel axis rotation can be used to solve the above problems.
Disclosure of Invention
The synchronous driving mechanism with parallel axes rotation comprises a basic frame and a group of rotating members which are arranged at intervals and are arranged in the basic frame, and the rotating axes of each rotating member are parallel to each other. Each of the rotating members has an eccentric crank pin parallel to its axis. One driving member is hinged to the crank pins of all the rotating members. The driving component is operated to enable all the rotating components to synchronously rotate so as to drive various mechanical running functions, for example: turning of the threads, vehicle steering, and multi-functional linkage.
The features relating to the present invention will be more readily understood by further reference to the following description and appended drawings.

Detailed Description
A first embodiment of a synchronous drive mechanism for parallel axis rotation is shown at 10 in the drawings, which uses a very small number of parts to drive a set of rotating member bodies having axes parallel to each other. A first embodiment of a synchronous drive mechanism for parallel axis rotation can be seen in fig. 1-3. Reference numeral 10 in the drawings includes a synchronous drive mechanism for driving a plurality of rotations along their parallel axes. The synchronous drive mechanism 10 includes a housing 20, a plurality of rotating members 30 mounted on the housing 20, a drive assembly 40 hingedly coupled to the rotating members 30 for driving the rotating members 30 to rotate along with themselves, and a cover 50 detachable from the housing 20. As shown in fig. 1-3, the synchronous drive mechanism 10 simultaneously drives a plurality of bolts to complete connection or disconnection of mechanical parts, such as the open end of a pipe or the installation of a wheel on a wheel hub.
The housing 20 is a substantially hollow cylindrical housing having a substantially closed base 25 at one end, an outer sidewall 21 extending from the outer periphery of the base 25, and an open end. The outer side wall 21 is generally disposed around the outer shape of the housing 20.
The housing 20 also has a central hub 23 extending axially from the center of the base 25, the hub 23 being a hollow structure which may be slightly taller than the outer side wall 21. An annular region 26 in the housing 20 intermediate the outer side wall 21 and the central hub 23 provides a mounting space for mounting a set of rotating members 30. The central hub 23 provides mounting support for the closure 50 or other components requiring axial passage.
The rotating member 30 includes a substantially crank eccentric plate 31, an eccentric crank pin 32 having a geometrical length protruding outwardly from one side of the crank eccentric plate 31, and an elongated connecting portion 33 protruding outwardly from the other side of the crank eccentric plate 31. Each crank eccentric 31 may preferably be in the form of a circular disc or may have any other geometrical shape, and is in principle made to facilitate the rotation of the connecting portion 33 in cooperation with the crank pin 32 under load. The connecting portion 33 is the rotation axis of each rotating member 30, and each individual rotating body of the rotating member 30 can be arranged in any spatial interval in the annular region 26, so that each individual connecting portion 33 passes through the corresponding opening or through hole 24 on the base 25 of the housing 20. Note that as shown in fig. 2, the individual rotors of the rotating member 30 adopt spaced mounting positions and the axes of rotation are parallel to each other. Since the spacing between the rotating members 30 can be designed at will, and can be arranged regularly or irregularly, the spacing distance between each pair of rotating members 30 must be constant and connected to and following the driving assembly 40.
The drive assembly 40 drives all of the rotating members 30 inside the housing 20 to rotate in unison. The drive assembly 40 includes: a drive mechanism 41 having a plurality of drive holes 42. The drive mechanism 41 takes the form of an annular ring having a diameter sized to fit the internal dimensions of the annular region 26 and allow the central hub 23 to pass through the annular drive mechanism 41. Each drive aperture 42 requires an articulated fit with the crank pin 32. The crank pin 32 of each rotor 30 is located off-center from the axis of rotation of the corresponding rotor 30. Thus, upon assembly, the trajectory of the rotation of the driving mechanism 41 about the central hub 23 will drive all the crank pins 32 hinged thereto to rotate and bring the rotating members 30 corresponding thereto to rotate.
The drive assembly 40 includes: a power assembly, such as a drive nut 43, powers the drive mechanism 41. An engagement boss 43a extends from the bottom end of the drive nut 43, and a tool boss 44 is provided at the top end of the drive nut 43. The through hole 46 penetrates the drive nut 43. When the through hole 46 is hinged to any one of the crank pins 32 of the rotary member 30, the engaging boss 43a at the bottom end contacts the inner edge of the driving mechanism 41. The length and thickness of the bottom end engagement collar 43a is preferably configured to conform to the thickness of the drive mechanism 41 so that the bottom surface of the drive nut 43 is coplanar with the top contact of the drive mechanism 41 during use and operation. Thus, the difference in height between the bottom engagement collar 43a of slightly smaller area and the bottom of the drive nut 43 of slightly larger area allows the engagement collar 43a to be inserted into the top of the drive mechanism 41. The tool bushing 44 includes a tool guide slot 45. The driving tool may be a hand-operated or a tool having a power source such as a hexagonal wrench.
The cover 50 is used to close the open end of the housing 20 in which the rotating member 30 and the drive assembly 40 are mounted. The closure 50 is typically a hollow, barreled housing disposed at one end of the housing 20 and having a substantially closed top wall 54. The outer side wall 51 extends from the top wall 54. The other end of the cap 50 is open. The outer sidewall 51 is generally the shape of the top of the closure 50. A flange 22 extends upwardly from the top end of the outer side wall 21 of the housing 20, and an outer side wall 51 is sealingly engaged with the flange 22 when assembled.
The closure 50 also includes a central through hole 53, the central through hole 53 being sized to allow passage of the central hub 23 and to allow the central hub 23 to extend from the closure 50 during assembly. The top wall 54 is formed with a driver tool insertion aperture 52. The driver tool insertion aperture 52 should be sized to match the tool sleeve 44 so that it can fit freely along the aperture. The height or length of the tool collar 44 is such that it conforms to the surface of the top wall 54 and extends from the closure 50 to a desired height.
In use, the drive tool is used to operate the drive nut 43, causing the drive nut 43 to rotate and the drive mechanism 41 to orbit about the central hub 23. Because the crank pins 32 of all of the rotating members 30 are connected to the drive mechanism 41 through their corresponding drive holes 42, the orbital motion of the drive mechanism 41 will cause all of the rotating members 30 to rotate simultaneously. The outer surface of the connecting portion 33 can be tapped to function as a fastening bolt, so that the component CP can be connected with the synchronous driving mechanism 10 through the CPH threaded hole in a one-off multi-bolt fastening manner. The multi-bolt synchronous tightening device can be broadly regarded as an end cap of any closed body, and a wheel hub is tightly connected with a bolt tightening flange of an axle end or a bolt flange of a pipeline system.
The rotating members 30 are normally operated simultaneously, and the distance between the axes of the parallel shafts should be kept constant when at least one pair of adjacent rotating members 30 rotate. The arrangement of the rotary members 30 can be arbitrarily set as long as the adjacent wheelbases are kept constant. The crank length (or distance between the axis of rotation and the crank pin 32) of each rotating member 30 should also remain equal and constant. The manufacturing of the rotation member 30 can be more diversified as long as the above two cases are satisfied. In other words, the shape and function of each individual rotating member 30 may be different from the other rotating members 30 in the same synchronous drive mechanism 10. The rotating member 30 need not be identical to the structure shown in the drawings.
In addition, as described above, the synchronous operation of the rotating members 30 can be achieved by driving any one of the rotating bodies of the rotating members 30, for example, the driving nut 43 can be directly connected to any one of the rotating bodies of the rotating members 30. Without being limited thereto, other rotating bodies of the rotating member 30 may be replaced with the driving driver, with appropriate modifications.
A second example of a synchronous drive mechanism 100 that rotates about parallel axes can be seen in fig. 4-6. In this embodiment, the synchronous drive mechanism 100 is essentially identical in construction and function to the synchronous drive mechanism 10, except for one drive assembly 140. The following description will be directed primarily to the drive assembly 140. In the "100" series, the basic features are all similarly referenced with numerals, if noted otherwise.
To eliminate the difficulty in driving the rotating member with an eccentric nut, which may be encountered with torque imbalance using a common tool such as a wrench or screwdriver, assembly of the drive assembly 140 may be simplified to the synchronous drive mechanism 100. For example, the position of the tool bushing 44 on the synchronous drive mechanism 10 is offset from the centerline of the overall mechanism. The drive assembly 140 has a drive assembly, such as a drive disk 143 mounted within the annular drive mechanism 141, and includes a through hole offset from the center of the drive disk 143. A driving boss 144 extending outward along the central axis of the through hole, and a plurality of slits 145 formed along the top end of the driving boss 144. The drive sleeve 144 may be made hollow and sized to mate with the central hub 123. The drive sleeve 144 and the cutout 145 are formed as a merlon structure, the cutout 145 being adapted to receive a tool for rotating the drive disk 143 about the central hub 123.
The cover 150 is similar to the cover 50 and has a central through hole 153 that is rotatable about the periphery of the central hub 123. The thickness of the central throughbore 153 is matched to the drive hub 144 so that the drive hub 144 can extend in a predetermined direction along the central hub 123. Unlike the previously described closure 50, the closure 150 does not include an eccentric drive tool insertion aperture 52.
In use, a user inserts a tool into the cutout 145 and rotates the drive plate 143. The drive disk 143 acts as a cam crank, the rotation of which causes the drive mechanism 141 to orbit the central hub 123 and thereby simultaneously rotate the attached rotating member 130. Since the rotation of the driving disk 143 is caused by the central shaft of the synchronous drive mechanism 100, the difficulty of the resistance imbalance is reduced when synchronously rotating the rotating member 130.
A third embodiment of a synchronous drive mechanism 200 for parallel axis rotation is illustrated in fig. 7. In this embodiment, the synchronous driving mechanism 200 can simultaneously drive a plurality of sub-driving mechanisms to synchronously operate in a chain structure manner.
As shown, the synchronous drive mechanism 200 has a housing 220, a plurality of rotating members 230 mounted inside the housing 220, a drive assembly 240 associated with the rotating members 230 for simultaneously driving each rotating member 230, and a removable cover 250 mounted on the housing 220. Each rotating member 230 simultaneously drives a respective sub-parallel axis synchronous drive mechanism. In the example shown in fig. 7, these sub-parallel axis synchronous drive mechanisms are indicated at 260.
The housing 220 is substantially hollow, having a rectangular shape with a base 225 at one end and an outer sidewall 221 extending from the base 225. The other end of the housing 220 is open. The outer sidewall 221 generally fits the housing 220 in a rectangular geometry.
Each of the rotating members 230 is a sub-drive system for operating or turning the direction of movement of a steering wheel, i.e., wheel 262, on the corresponding subsystem rolling assembly 260. Each rotating member 230 is generally fabricated in a similar configuration as rotating member 130, such that rotation of each rotating member 230 causes the rolling subsystems to act in temporal synchrony. Each of the rotary members 230 includes a rotary housing 231 and an eccentric crank pin 232.
To facilitate simultaneous movement of the wheels 262 in each subsystem rolling assembly 260, each rolling assembly swivel housing 231 may include, for example, as many transfer mechanisms as there are wheels 262. Each transfer gear may be paired with a wheel 262 by means of a tie rod, chain or the like so that rotation of each transfer gear causes rotation of each wheel 262 in the desired direction.
As in the previous embodiment, the driving assembly 240 drives all the rotating members 230 inside the housing 220 to rotate toward each other instantaneously. The driving assembly 240 includes: a drive mechanism 241 having a plurality of drive apertures 242 is provided. The drive mechanism 241 may be formed as a rectangular ring sized to fit within the housing 220 and facilitate a reasonable amount of movement. The rectangular ring is sized to ensure that the rectangular ring orbits around the geometric center of the housing 220. Each drive aperture 242 is sized to receive an eccentric crank pin 232 during assembly. The crank pin 232 of each rotary member 230 is mounted on the corresponding rotary member 230 at a position offset from the rotational axis. Thus, when assembled, the orbital motion of the driving mechanism 241 about the geometric center forces all of the rotating members 230 connected to the crank pin 232 to rotate. In this embodiment, the rotating members 230 are arranged near the corners of the housing 220.
Similar to the synchronous drive mechanism 10, the synchronous drive mechanism 200 further includes a cover 250 having a tool insertion aperture 252. Operation of the drive mechanism 241 may be accomplished by selectively connecting one or more crank pins 232 through the tool insertion hole 252 with a tool or mechanical assembly. Rotation of one or more crank pins 232 activates the remaining rotating members 230 to rotate simultaneously as they are interconnected with the drive mechanism 241. It can be seen that drive assembly 240 provides a primary drive system in the form of a rotating member 230 that is coupled to one or more auxiliary subsystems. In all other respects, the operation of the simultaneous drivable apparatus 200 is substantially the same as in the previously described embodiment.
A fourth example of a synchronous drive mechanism 300 for rotation about parallel axes is seen in fig. 8. The synchronous drive mechanism 300 is an embodiment of a steering control for multiple rolling assemblies. Note that the term "face" herein refers to a face oriented during user-operated steering.
The synchronous drive mechanism 300 has a base 320, a plurality of rotating members 330 rotatably mounted on the base 320, and a drive assembly 340 coupled to the rotating members 330 and capable of simultaneously rotating the rotating members 330. In fig. 8, each rotating member 330 is coupled to a respective rolling assembly 360.
The base 320 is formed as a platform having a plurality of extendable base arms 321 extending from the center. Each rotating member 330 is rotatably mounted to the end of the base arm 321. Each rotating member 330 includes an extendable crank arm 331 and an off-center crank pin 332 extending from one end of the crank arm 331. The other end of the crank arm 331 is connected to a corresponding rolling assembly 360. Each rolling assembly 360 is preferably a wheel 362, similar to wheel 262 in the previous case. These wheels 262, and the wheels described above, are steerable about their axis of rotation, i.e., 360 degrees, to provide more flexibility in the travel mechanism.
The drive assembly 340 includes a drive mechanism 341 that is coupled to all of the crank pins 332. The drive mechanism 341 is preferably formed similar to the base 320, with an extendable, adjustable drive arm 341a mating with the base corresponding to the base arm 321. The drive arm 341a and the base arm 321 should have equal lengths. It should be noted that the shape and size of the driver 341 can vary so long as the driver can be operatively connected to the crank pin 332. The drive mechanism 341 provides one or more drive holes 342 near the end of each drive arm 341a for connection to a corresponding crank pin 332.
The operation of the rolling assembly 360 is performed by a user sitting on the optionally rotatable seat S. In use, a user sits on the seat S to rotate the seat in a desired direction of travel. The seats S are mounted on the drive mechanism 341 so that turning the seats S causes the drive mechanism 341 to turn in the same direction at the same time. In other words, rotation of the seat S will generate a torque that drives the drive assembly 340 to rotate in opposite directions with the seat S. The normal function of the synchrodrive mechanism 300 is to maintain instantaneous synchronous steering of the seat S and wheels 362 during steering. However, the seat S may be designed to rotate freely relative to the drive assembly, such that the "facing" of the user may be designed in any direction. That is, the ensuing steering can be rotated relative to this new "face". For example, the seat S "faces" north, and all of the wheels 362 "roll" east, so that turning the seat clockwise or counterclockwise rotates the seat with all of the travel wheels 362 clockwise or counterclockwise, south or north. This offset steering between the seat S and the drive assembly 340 can be controllably adjusted by constructing a ratchet arrangement therebetween.
The connection point of the seat S is at the geometric center or convergence of the drive arms 341 a. To facilitate rotation of the drive mechanism 341, the attachment point of the seat S may be offset from the geometric center of the drive mechanism 341 so that the seat S functions as an eccentric lever for the drive mechanism 341. Since the crank pin 332 and the crank arm 331 are coupled to each other, the rotation of the driving mechanism 341 instantaneously synchronizes the rotation of the rolling assembly 360 and manipulates the rolling assembly 360 to move in a desired direction.
It can be seen that the synchronous drive mechanisms 10,100,200 have a variety of alternative options. For example, the rotating member 30,130,230,330 can be made as a radially reciprocating part, such as a lock. Further, the synchronous drive mechanisms 10,100,200,300 may be used in a number of mechanical systems having similar or different operational requirements. The synchronous operation of the synchronous drive mechanisms 10,100,200,300 significantly reduces time and improves efficiency over operating a single system.
It is understood that the present invention should not be limited to the embodiments described above, but rather should be construed in breadth and scope in accordance with the appended claims.
