Description
Technical field
The utility model relates to the gear drive that a kind of energy stepping changes output shaft and input shaft velocity ratio, particularly relates to a kind of rotation speed adjusting type speed changer.
Background technique
Existing speed changer has mostly adopted shifting slide gear to realize gear shift.Find that through inventor's long-term observation it obviously has complex structure, from great, volume is big, makes, installs, uses inconvenience, and inconvenience realizes the self-shifting defective.And this speed changer is when being used for automatic transmission gas car, and it is many also to have a shifting element, the defective that rate of fault is high.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, and the little and lightweight rotation speed adjusting type of a kind of volume speed changer is provided.
For achieving the above object, this practicality rotation speed adjusting type speed changer comprise two corresponding by a plurality of combined type main wheels that constitute with the roller gear, all be furnished with a planetary pinion that is used for power transmission between two main wheels between each antithetical phrase gear, each planetary pinion is distributed in can be on the planetary wheel carrier of one of them main axle rotation; At least one main wheel is made of the different multistage sub-gear of arranging according to the order of sequence of diameter.The design that at least one main wheel is made of the different multistage sub-gear of arranging according to the order of sequence of diameter, can guarantee the realization of speed changing function, certainly, if two main wheels all adopt the design that is made of the different multistage sub-gear of arranging according to the order of sequence of diameter, and oppositely cooperate, then can increase gear ratio greatly, improve gearshift performance.So design can be carried out the transmission of power by the planet wheel on the planetary wheel carrier between two main wheels, and can select the sub-gear in different wheels footpath to carry out speed change by changing different planet wheels.Because the sub-gear of each main wheel all adopts coaxial-type, each planet wheel all is installed on the same planetary wheel carrier, and therefore, it has compact structure, and volume is little, and is in light weight, and gear shift mode is fast reliable, the advantage that power transmission efficiency is high.
As optimization, the main wheel that is made of the different multistage sub-gear of arranging according to the order of sequence of diameter is trapezoid shaped, and planetary wheel carrier is coated on the periphery of one of them main wheel.Two main wheels can all be trapezoid shaped simultaneously, and also only a main wheel is trapezoid shaped.Planet wheel Zhou Xianglian is outside passed through in so design between main wheel and the main wheel, more convenient manufacturing, mounting, commissioning and maintenance, and structural strength is also higher, is more suitable in big torsion transmission.
As optimization, two main wheels all are made of the different multistage sub-gear of arranging according to the order of sequence of diameter, all are the trapezoid shaped of mutual correspondence, and are combined together by planetary pinion and planetary wheel carrier mutually with being inverted.So design more helps increasing gear ratio.
As optimization, one of them main wheel is a follower, by constituting and be trapezoid shaped to the formula gear in different multistage of the diameter of arranging according to the order of sequence, another main wheel is that driving wheel is made up of the less sub-gear of the diameter of a plurality of outboard types, and be sleeved within the follower, planetary wheel carrier is sleeved between two main wheels, and the axis misalignment of two main wheels.So design, help reducing the volume of speed changer.
As optimization, in every group of corresponding gear: the number of teeth of the sub-gear of driving wheel is less than the planetary number of teeth, and the planetary number of teeth is less than the number of teeth of the sub-gear of follower.So design is compared with the preceding paragraph design and more to be helped increasing gear ratio.
As optimization, in the form of annular discs by the main wheel that the different multistage sub-gear of arranging according to the order of sequence of diameter constitutes, the gear teeth of multistage sub-gear all are positioned on the same one side of this dish type main wheel; Planetary wheel carrier also is disc and covers on the flank of tooth of this disc main wheel, or planetary wheel carrier is drum shape and is coated on and corresponding another main wheel periphery of this disc main wheel.So design, more help reducing the volume of speed changer.
As optimization, more preferably planetary wheel carrier also is disc and covers on the flank of tooth of this dish type main wheel.Volume and its mechanical strength of assurance of being more convenient for dwindling speed changer compared in so design with the preceding paragraph design.
As optimization, be fitted with on the planetary wheel carrier and the corresponding rotary positioning apparatus in the position of each planetary pinion between two main wheels.So design is freely to change in order to be implemented between each gear, makes each planet wheel each antithetical phrase gear corresponding with it meshing better, guarantees the reliability that gear shift and torsion transmit.
As optimization, the preferred band brake type of the positioning work piece of rotary positioning apparatus, the rotation driving mode of rotary positioning apparatus can be electronic also can be manual.The band brake type positioning work piece also comprises the planetary pinion position transducer, and this sensor can instruct band-type brake fixing planetary carrier exactly.So design, band brake type positioning work piece and electrodynamic type rotation driving mode are more convenient for realizing automatic control, i.e. automation; Then structure is simpler for manually operated type rotation driving mode.
As optimization, equate that with adjacent planetary angular distance between last planetary pinion adjacent sub-gear has identical public figure place with planetary pinion at first planetary pinion at least.So design, the planetary pinion distributed architecture that angular distance equates more helps manufacturing and designing of rotary positioning apparatus and installs and uses, the sub-gear of the identical public figure place of the latter and planetary pinion design then more help joining speed and reducing wear of three, and make gear shift more convenient smoothly.
Special needs to be pointed out is that to have a volume little because the utility model rotation speed adjusting type speed changer is compared with existing sliding speed changer, in light weight, the transmission efficiency height, the advantage of good reliability, therefore it is more suitable for realizing the automation speed governing and uses these traffic tool such as automobile, aircraft etc. on to the volume and the demanding traffic tool of weight.
After adopting technique scheme, the utility model rotation speed adjusting type speed changer has simple and compact for structure, volume is little, and is in light weight, and gear shift mode is simple and easy to do, good reliability, make easy to installly, the transmission efficiency height can also adapt to big torsion speed change, more convenient realization automatic speed changing, the advantage that adaptability is good and popularizing prospect is wide.Be more suitable in being applied on the traffic tool that the speed changer volume and weight is had relatively high expectations, as automobile, aircraft etc.
