Abstract
The utility model relates to the technical field of clutches, and in particular relates to a nine-roller type overrun clutch. The nine-roller type overrun clutch comprises an outer cover, an outer ring, a spring, a spring cap, rollers and clamping jaws, wherein the outer cover is connected with the outer ring; the spring, the spring cap and the rollers are arranged on the outer ring; the spring cap is arranged between the spring and the rollers; and the clamping jaws are arranged at the periphery of a central hole of the outer cover. The nine-roller type overrun clutch is simple, compact and reasonable in structure, convenient and rapid to assemble and reliable in connection, the problem that the spring and the rollers easily drop when a unidirectional overrun clutch works is solved, the rollers are uniformly stressed, the service life of the overrun clutch is prolonged, the operating reliability of the overrun clutch is greatly improved, and the nine-roller type overrun clutch is easy to use and popularize.
Description
Technical field
The utility model relates to a kind of technical field of clutch, especially a kind of nine roller type free wheel devicees.
Background technique
The spring of existing nine roller-type overrunning clutch adopts sheet structure, receives the influence of spring structure on chip, and the suffered elastic force of roller is difficult to evenly; And spring radially is difficult to fix; Spring and roller drop easily, and the pad that protection is simultaneously used is separation-type, and packed and transported is cumbersome with assembling.
The model utility content
Be prone to come off and assemble the deficiency that bothers in order to overcome existing nine roller-type overrunning clutch roller discontinuity, spring and roller, the utility model provides a kind of nine roller type free wheel devicees.
The utility model solves the technological scheme that its technical problem adopted: a kind of nine roller type free wheel devicees; Comprise outer cover, outer ring, spring, spring compressor, roller and claw; Outer cover is connected with the outer ring; The outer ring is provided with spring, spring compressor and roller, is provided with spring compressor between spring and the roller, is provided with claw around the outer cover center hole.
According to another embodiment of the utility model, comprise that further outer cover is provided with oilhole, oilhole quantity is at least 9.
According to another embodiment of the utility model, comprise that further outer ring one side is provided with pad.
According to another embodiment of the utility model, comprise that further the outer ring is connected through tapped hole with pad, tapped hole quantity is 3.
According to another embodiment of the utility model, comprise that further spring is the steel wire helix structure, the cross section is a racetrack.
According to another embodiment of the utility model, comprise that further claw quantity is 9.
The beneficial effect of the utility model is that this nine roller type free wheel devicees are simple in structure, compact and reasonable, and are easy to assembly quick; Connect reliable; The problem that spring and roller are prone to drop when having solved mono-directional overrun clutch work, roller is stressed more even, has prolonged the working life of free wheel device; Improved the reliability of free wheel device work greatly, be easy to use and promote.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of the utility model;
Fig. 3 is the plan view of the utility model.
1. outer covers among the figure, 2. outer ring, 3. spring, 4. spring compressor, 5. roller, 6. claw, 7. oilhole, 8. pad, 9. tapped hole.
Embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of nine roller type free wheel devicees comprise outer cover 1, outer ring 2, spring 3, spring compressor 4, roller 5 and claw 6; Outer cover 1 is connected with outer ring 2, and outer ring 2 is provided with spring 3, spring compressor 4 and roller 5, is provided with spring compressor 4 between spring 3 and the roller 5; Be provided with claw 6 around outer cover 1 center hole, outer cover 1 is provided with oilhole 7, and oilhole 7 quantity are at least 9; Outer ring 2 one sides are provided with pad 8, and outer cover 1 is connected through tapped hole 9 with outer ring 2, and tapped hole 9 quantity are 3; Spring 3 is the steel wire helix structure, and the cross section is a racetrack, and claw 6 quantity are 9.
During use, outer cover 1 forms through 9 riveted joints of 3 tapped holes with outer ring 2, has avoided 2 of outer cover 1 and outer rings to produce relative displacement; Dashing on outer cover 1 plane has at least 9 oilholes 7, when mono-directional overrun clutch is worked, can carry out lubricating fully to roller 5, prolongs the working life of mono-directional overrun clutch; Outer cover 1 central hole processes the assembling enclosed space of 9 claws 6 and outer ring 2 assembling back formation springs 3 and spring compressor 4, and spring 3 is done straight line motion in this enclosed space, solved the problem that spring 3 and roller 5 are prone to drop; Increase spring compressor 4 at spring 3 and 5 on roller; Avoid roller 5 directly to contact and make that spring 3 wear and rupture, spring 3 change the steel wire helix structure into by sheet structure, and the cross section is a racetrack with spring 3; Make roller 5 stressed more even; Elastic force is prone to be machined in the predetermined range, and pad 8 connects into integral body with outer ring 2, can prevent better that spring and roller from dropping.This nine roller type free wheel devicees are simple in structure, compact and reasonable; Easy to assembly quick, connect reliably the problem that spring and roller are prone to drop when having solved mono-directional overrun clutch work; Roller is stressed more even; Prolonged the working life of free wheel device, improved the reliability of free wheel device work greatly, be easy to use and promote.
