Abstract
The invention discloses a bearing type overrunning clutch, which is provided with retaining brackets which are arranged corresponding to rollers one to one. A wedge slot for engagement consists of arc segments concentric to an inner ring in transition, and a V-shaped opening of an elastic supporting claw of each retaining bracket is opposite to an engaged part of a wedged engagement space to support each roller along a circumferential direction. By the overrunning clutch, a bearing can be replaced, the cost is saved, the volume of a transmission system is reduced, a limiting seat is prevented from being directly machined on the inner ring or an outer ring, the machining process is simplified, the working efficiency is improved, and the machining cost is reduced; the positions of the rollers can be flexibly adjusted in the circumferential direction according to the need, and the machining and assembling precision is guaranteed; more rollers can be distributed in the circumferential direction, the bearing capacity is improved, and the dimension of the overrunning clutch can be reduced under the condition of higher bearing capacity; meanwhile, due to the elastic supporting claw, line contact limiting is formed, and a condition that the rollers deviate an axis due to imbalanced limiting is avoided; therefore, a mechanical failure caused by instable operation of the overrunning clutch is avoided.
Description
Technical field
The present invention relates to a kind of clutch equipment that is used for motor vehicle transmission, particularly a kind of free wheel device.
Background technique
Free wheel device is the basic components that occur along with the development of power product, and it is to be used between prime mover and the working machine or the vitals of transmission of power and separation function between machine intimate driving shaft and the driven shaft.Mainly be the conversion that utilizes the velocity variations or the sense of rotation of driving and driven part, have the device of clutch function voluntarily.In the practice, most is the engagement that utilizes tooth, engagement or roller, the wedge action unidirectional delivery motion of voussoir or the clutch of moment of torsion of ratchet-ratchet.
Roller overrunning clutch is because transmission is uniform and stable and bearing capacity is bigger, thereby obtains using comparatively widely in the occasion of fair speed; The roller-type overrunning clutch root in it yoke (star-wheel) position difference be divided into two kinds of out star wheel and star-wheels, star-wheel is provided with the groove that holds roller, simultaneously, when breaking away from engagement, in order to limit the backward rotation of roller, then need to be provided with limit stoper, this device generally comprises position limit socket and elastic element.Position limit socket generally is positioned at inner ring or the outer ring is one-body molded, and course of working is comparatively complicated, not only reduces working efficiency, also makes processing cost higher.Because integrated formed structure can't be adjusted circumferential position according to use condition.Thereby, for the ease of processing with guarantee machining accuracy, being widely adopted of star-wheel formula; But for the structure of outer ring, be unfavorable for adapting to the transmission rule of free wheel device, cause its shortening in working life or influence the transmission effect as the active transmission.
Because existing overrun is used to limit the position limit socket and the elastic element of roller, take bigger spatial position, cause and be more than clutch and can't arrange more roller, roller then is the load-bearing component that is more than the clutch outbalance, and the restriction of quantity badly influences the bearing capacity of free wheel device; Thereby in manufacture process, will consider increased in size to adapt to bearing capacity, cause the size of transmission device bigger, the needs of incompatibility modern machinery and equipment.There is the elastic element of being exactly to act on roller again and limits it and oppositely mesh, act on a bit local in other words on the roller, can not reach balance, make the easy deflection of roller, cause consequence stuck or that motion is not smooth, thereby cause mechanical failure at circumferencial direction.
The roller-type overrunning clutch of prior art is used for transmission system, rolling bearing need be set support, otherwise unstable phenomenon can occur, does not reach required transmission effect; Owing to increased bearing structure, this has just increased the volume of transmission system, and increases the complexity of installing, safeguarding and dismantling, and improves user cost.
Therefore, need improve existing overrun, can remove the auxiliary bearing of being installed when existing overrun is used, and can simplify the course of working of free wheel device itself, increase work efficiency, cut down finished cost, can adjust roller flexibly as required in circumferential position, guarantee processing and assembly precision, increase the service life and guarantee the transmission effect; Can arrange more relatively roller, and reduce to avoid because the problem of the free wheel device fluctuation of service that spacing imbalance causes than the free wheel device size under the high bearing capacity.
Summary of the invention
