Description
Technical field
The utility model relates to Clutch Technology field, particularly relates to a kind of needle roller free wheel device.
Background technique
Free wheel device can be widely used in automobile, motorcycle, electrician tool, fitness equipments, household electric appliance, toy, printing press etc.
Clutch is in combination with in the process be separated, and when running into impact, the elastic reaction mutual by spring can alleviate impact, plays the protective action to clutch.But clutch is when using certain time limit, spring easily occurs to loosen and drops, and so just weakens the protective value of spring in clutch working procedure.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of needle roller free wheel device; the firm effect to spring position can be played; the problem easily dropped after avoiding spring Long-Time Service; ensure that the working life of spring; ensure that clutch Long-Time Service rear spring still has excellent protective value, extend the life time of clutch.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of needle roller free wheel device, comprise: circular platen, U-shaped chamber and spacing block set, the surface of described circular platen inner ring offers at least one U-shaped chamber, the bottom in described U-shaped chamber is provided with needle roller, the top in U-shaped chamber is provided with the spring contacting with needle roller and connect, be that distance is arranged between the bottom interior wall in described needle roller and U-shaped chamber, the bottom interior wall in U-shaped chamber is also provided with a spacing block set, and the top of described spacing block set and the bottom gap of needle roller are arranged.
In the utility model preferred embodiment, described U-shaped chamber and circular platen are formed in one and arrange.
In the utility model preferred embodiment, described circular platen outer ring is provided with at least one groove.
In the utility model preferred embodiment, described spacing block set is elastic spacing projection.
In the utility model preferred embodiment, the bottom interior wall in described spacing block set and U-shaped chamber is arranged for sliding.
The beneficial effects of the utility model are: the utility model needle roller free wheel device can play the firm effect to spring position; the problem easily dropped after avoiding spring Long-Time Service; ensure that the working life of spring; ensure that clutch Long-Time Service rear spring still has excellent protective value, extend the life time of clutch.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of needle roller free wheel device one of the present utility model preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, circular platen, and 2, U-shaped chamber, 3, needle roller, 4, spring, 5, spacing block set, 6, groove.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of needle roller free wheel device, is characterized in that, comprising: circular platen 1, U-shaped chamber 2 and spacing block set 5, the surface of described circular platen 1 inner ring offers at least one U-shaped chamber 2, and described U-shaped chamber 2 is formed in one with circular platen 1 and arranges.
The bottom in described U-shaped chamber 2 is provided with needle roller 3, and the top in U-shaped chamber 2 is provided with the spring 4 contacting with needle roller 3 and connect.Be that distance is arranged between described needle roller 3 and the bottom interior wall in U-shaped chamber 2, the bottom interior wall in U-shaped chamber 2 is also provided with a spacing block set 5, and the top of described spacing block set 5 and the bottom gap of needle roller 3 are arranged.
Spacing block set 5 can by the abutting of needle roller 3 and then the firm effect that plays spring 4 position; the problem easily dropped after avoiding spring 4 Long-Time Service; ensure that the working life of spring 4; ensure that clutch Long-Time Service rear spring 4 still has excellent protective value, extend the life time of clutch.
Described spacing block set 5 is elastic spacing projection, and cost of production is low, and the friction contacting rear generation with needle roller 3 is few.Described spacing block set 5 is arranged for sliding with the bottom interior wall in U-shaped chamber 2, effectively can abut, and then can improve the firm effect to spring 4 according to the working position of needle roller.
Described circular platen outer ring 1 is provided with at least one groove 6, and groove 6 can ensure the smooth engagement of clutch cohesive process, and not easily skid wearing and tearing, not easily sideslip.
The beneficial effect of the utility model needle roller free wheel device is:
By to the abutting of needle roller and then the firm effect that can play spring position; the problem easily dropped after avoiding spring Long-Time Service; ensure that the working life of spring, ensure that clutch Long-Time Service rear spring still has excellent protective value, extend the life time of clutch.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
