Abstract
A kind of mono-directional overrun clutch of improvement; it is arranged in the step hole of housing by existing overrunning clutch; and in overrunning clutch, between inner end and step hole inner end, friction plate is set; and at step hole oral area, butterfly spring and end cap are installed; the utility model can play overload protection effect, avoids therefore to the damage of overrunning clutch.
Description
Technical field
The utility model relates to clutch, is specifically related to mono-directional overrun clutch, belongs to free wheel device technical field.
Background technique
Well-known: mono-directional overrun clutch major function is forward transmitted load, then not transmitted load in the other direction, overrunning clutch structurally generally to rely on and is arranged on inner spring sheet and carrys out transmitted load, thus, when payload overload, the cell body often easily damaging spring sheet and agree with mutually with spring sheet.To this, existing mono-directional overrun clutch does not generally have good solution.
Summary of the invention
The purpose of this utility model is: for the easy damage spring sheet existing for existing mono-directional overrun clutch and the defect of cell body of agreeing with mutually with spring sheet; the utility model provides a kind of mono-directional overrun clutch of improvement; the mono-directional overrun clutch that this kind improves; in the case of an overload; overload protection effect can be played, avoid therefore to the damage of overrunning clutch.
The utility model realizes the technological scheme that above-mentioned purpose adopts: the mono-directional overrun clutch of described a kind of improvement, it is by housing, mono-directional overrun clutch, friction plate, butterfly spring, end cap, bolt formed, it is characterized in that: in described housing, be shaped with step hole, in step hole, inner end is fixed with friction plate, mono-directional overrun clutch is arranged in the step hole of housing, wherein, the inner circle of mono-directional overrun clutch cylindrical and step hole has more small gap, inner end and friction plate close contact in mono-directional overrun clutch, at the oral area of step hole, some dress butterfly springs are set, an end cap is fixed at the step hole port part bolt of housing end face, described end cap compresses mono-directional overrun clutch by butterfly spring.
Working principle of the present utility model is: under normal circumstances; overrunning clutch and shell, due to the effect of frictional force, become complete one, when overloading; occur between mono-directional overrun clutch and housing mutually to rotate, thus realize the effect of overload protection.
Beneficial effect: the utility model, due to when overloading, occurring between mono-directional overrun clutch and housing mutually to rotate, thus realizing the effect of overload protection; so; in the case of an overload, overload protection effect can be played, avoid therefore to the damage of overrunning clutch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Shown in figure: 1 is housing; 2 is mono-directional overrun clutchs; 3 is friction plates; 4 is butterfly springs; 5 is end caps; 6 is bolts; 7 is step holes.
