Description
Technical field
The present invention relates to field of mechanical technique, especially relate to a kind of overrunning clutch sleeve.
Background technique
Free wheel device mainly is made up of component such as sleeve, rotatingshaft, roller, springs.Inwall at sleeve has several equally distributed wedge shape teeth groove, and each wedge shape teeth groove comprises curved working face and spring supporting surface.One end of spring acts on the spring supporting surface, and the other end acts on the roller, with the roller roof pressure on curved working face.Be provided with transition plane between working surface and the supporting plane.
Owing in the roller rolling process, can produce reaction force, and a component of reaction force has the movement tendency that makes spring disengaging spring supporting surface to spring.Spring supporting surface of the prior art probably causes spring to break away from the spring supporting surface when free wheel device is worked, and causes working stability to descend.
In order to address the above problem, the someone has invented a kind of free wheel device [application number: CN200610065502.8], comprises inner race, outer race, and it faces toward a plurality of depressions that are provided with in interior week of inner race periphery this outer race.Coil spring is arranged in a plurality of depressions, and this coil spring is pushed roller along a circumferencial direction of inner race and outer race.Between inner race and outer race, carry out transmission along a described circumferencial direction.The cross section of coil spring have the length direction that is parallel to roller than long side, respectively have the thin spring compressor of U-shaped of pair of sidewalls to be arranged in the end of spring.This scheme has improved the stability of coil spring work to a certain extent, but the structure of outer race is complicated, and the difficulty of processing of depression is big, the cost of production height.And the degree of depth of each depression is difficult to be consistent, and causes the pressure difference of each roller, influences the free wheel device working stability.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of reasonable in design is provided, simple structure, the contact stabilization between spring and the sleeve can not break away from, and the low overrunning clutch sleeve of cost of production
For achieving the above object, the present invention has adopted following technical proposal: overrunning clutch sleeve, be sheathed on the periphery of rotating shaft, be evenly distributed with some wedge shape teeth groove at sleeve lining, each wedge shape teeth groove comprises working surface and supporting plane that is used for the supported spring end of an arc, it is characterized in that, described working surface near the distance one between supporting plane one side and the sleeve center less than working surface away from the distance two between supporting plane one side and the sleeve center, be provided with transition plane between working surface and the supporting plane, the plane at described transition plane place and the plane shape at supporting plane place have angle, and described angle is an acute angle.
Because the angle that the plane at the plane at transition plane place and supporting plane place forms among the present invention is an acute angle, spring is subjected to being partial to the active force of wedge shape teeth groove working surface, and this active force can overcome the above-mentioned spring of mentioning that makes that in the roller rolling process spring is produced and has the reaction force of the movement tendency that breaks away from the spring supporting plane.By this structure, can effectively improve the stability of spring work, spring can not broken away from.On the other hand, structure of the present invention is very simple, and difficulty of processing is low, and is easy to implement, and has significant technological progress.
In above-mentioned overrunning clutch sleeve, the size of described angle is 60 °～89.5 °.The size of angle designs according to different size and specification, and in general angle is more little, and the working stability of spring is high more, but also can be corresponding the difficulty of raising processing.
In above-mentioned overrunning clutch sleeve, described transition plane respectively with working surface and supporting plane smooth connection.
In above-mentioned overrunning clutch sleeve, be provided with the connection cambered surface between described working surface and the sleeve lining, connect cambered surface respectively with working surface and sleeve lining smooth connection.
In above-mentioned overrunning clutch sleeve, described sleeve lining is evenly distributed with 3～50 wedge shape teeth groove.The number of the wedge shape teeth groove here designs as required, because the easiest five equilibrium that carries out of processing of six wedge shape teeth groove, therefore in actual applications, generally the inwall at sleeve processes equally distributed six wedge shape teeth groove.
Above-mentioned overrunning clutch sleeve makes by following method: a. sleeve blank preparation: prepare sleeve blank cylindraceous according to required size; B. working surface processing: process the working surface of arc at the inwall of sleeve blank, an end of working surface and the distance between the sleeve center are less than the distance between its other end and the sleeve center; C. supporting plane processing: the less side of distance processes supporting plane between working surface and sleeve center; D. transition plane processing: process transition plane between working surface and supporting plane, the plane shape at the plane at transition plane place and supporting plane place has angle, and angle is an acute angle; E. finished product: repeat above-mentioned steps b, c and d, process equally distributed several wedge shape teeth groove, promptly get overrunning clutch sleeve at the inwall of sleeve.In addition, can also between working surface and sleeve lining, process and connect cambered surface, connect cambered surface respectively with working surface and sleeve lining smooth connection.
The order of each process step among the present invention does not limit, and can adjust according to actual needs.
Compared with prior art, the advantage of this overrunning clutch sleeve is: 1, reasonable in design, simple in structure, the contact stabilization between spring and the sleeve can not break away from, and effectively improves working stability.2, manufacturing procedure is simple, and is easy to implement, and cost of production is low.
