Abstract
The invention relates to a clutch, in particular to a one-way clutch capable of preventing two-way sliding caused by the failure of supporting springs. The one-way clutch comprises a barrel-shaped sleeve. A plurality of grooves are uniformly formed in the inner wall of the sleeve. Each groove comprises an arc-shaped working face and an L-shaped spring supporting chamber, which are in circular arc transition connection. A rotating shaft is arranged in an inner hole of the sleeve. Rollers are arranged in the arc-shaped working faces. The supporting springs are arranged in the L-shaped spring supporting chambers. One end of each supporting spring is pressed on the corresponding roller, and the other ends of the supporting springs are pressed on the spring supporting faces of the L-shaped spring supporting chambers. The rollers are tangential to the arc-shaped working faces and the rotating shafts. The distances between the center of the sleeve and the connection parts between the L-shaped spring supporting chambers and the arc-shaped working faces are larger than those between the far ends of the arc-shaped working faces and the center of the sleeve. The one-way clutch realizes one-way torque transfer, and is reliable and stable in operation.
Description
Technical field
The present invention relates to clutch, specifically a kind of one-way clutch that can prevent because supporting the two-way skidding of spring failure.
Background technology
At present, all of automobile starter one-way clutch is mainly made up of parts such as sleeve, rotation axle, roller, support springs, inwall in sleeve body has several equally distributed grooves, and groove includes cambered rollers work surface and L-shaped spring supporting room. Support spring steel wire wound, with roller-contact be two steel wire cylindricals being connected, one end is supported on a face of L-shaped spring supporting room, and the other end acts on roller, roller top is pressed in curved working face and rotation axle between. Owing to of L-shaped spring supporting room smooth does not stop, during work, when roller stress moves forward, unbalance stress easily tilts, the direction of axis line supporting spring causes supporting spring centripetal deviation in change and rotates axle fretting wear and the deformation of spring bearing up-down force inequality, support spring initial failure, the two-way skidding of isolator.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that a kind of one-way clutch that can prevent because supporting the two-way skidding of spring failure.
According to technical scheme: a kind of one-way clutch that can prevent because supporting the two-way skidding of spring failure, it is characterized in that: include the sleeve of barrel shape, described sleeve lining is uniform arranges several grooves, and groove includes curved working face, the L-type spring supporting room that arc transition connects; Described hub internal bore arranges rotation axle, curved working face arranges roller, L-type spring supporting arranges support spring in room, described support spring one end is pressed on roller, the other end is pressed on the spring supporting face of L-type spring supporting room, described roller simultaneously with curved working face and to rotate axle tangent, and the distance of described L-type spring supporting the room far-end more than curved working face and bushing core with the junction of curved working face and the distance of bushing core.
As a further improvement on the present invention, the end of described L-type spring supporting room is downwardly extending projecting block, and described projecting block is circular arc or square.
As a further improvement on the present invention, between two support arms of described L-type spring supporting room angulation be α, α range for 80 ° ~ 95 °.
As a further improvement on the present invention, described support spring is about centrosymmetric pair of bow-shaped structural, the end supporting spring is embedded in the spring supporting face place of L-type spring supporting room, two the roller support faces supporting spring offset up and down with the crest line of roller respectively, two roller support faces flexible separate.
The method have technical effect that: product design of the present invention is skillfully constructed, sleeve designs curved working face and L-type spring supporting room, and the bottom land of curved working face is designed with radian shape, and the trend of this radian is the closer to side, L-type spring supporting room, further away from the center of sleeve, in order to realize one-way locking, namely when rotation axle rotates towards side, L-type spring supporting room, roller retreats towards supporting spring side, and compresses support spring, now isolator slipping; When rotation axle rotates towards projecting block side, roller moves to the curved working face far-end of sleeve, is lockable, now isolator transmission torque.

Fig. 2 is the support spring profile of the present invention.
Fig. 3 is the structural representation before the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 3, including sleeve 1, groove 1-1, curved working face 1-2, L-type spring supporting room 1-3, rotate axle 2, roller 3, support spring 4, L-type spring supporting room and the junction a of curved working face, the far-end b of curved working face, spring supporting face c, projecting block d, support the end face e of spring, roller support face f etc.
As shown in Fig. 1 ~ 3, the present invention is a kind of one-way clutch that can prevent because supporting the two-way skidding of spring failure, including the sleeve 1 of barrel shape, described sleeve 1 inner wall even distribution arranges several grooves 1-1, groove 1-1 and includes curved working face 1-2, the L-type spring supporting room 1-3 that arc transition connects; Described sleeve 1 endoporus arranges rotation axle 2, curved working face 1-2 arranges roller 3, L-type spring supporting room 1-3 arranges support spring 4, described support spring 4 one end is pressed on roller 3, the other end is pressed on the spring supporting face of L-type spring supporting room 1-3, described roller 3 simultaneously with curved working face 1-2 and to rotate axle 2 tangent, and the distance at the distance at the junction a of described L-type spring supporting room 1-3 and curved working face 1-2 and the sleeve 1 center far-end b place more than curved working face 1-2 and sleeve 1 center.
The end of L-type spring supporting room 1-3 is downwardly extending projecting block d, and described projecting block d is circular arc or square.
Between two support arms of L-type spring supporting room 1-3 angulation be α, α range for 80 ° ~ 95 °.
Supporting spring 4 is about centrosymmetric pair of bow-shaped structural, the end face e place supporting spring 4 is embedded in the c place, spring supporting face of L-type spring supporting room 1-3, two the roller support face f supporting spring 4 offset up and down with the crest line of roller 3 respectively, and two roller support face f's is flexible separate.
Principles of the invention is as follows: due to the distance at far-end b place more than curved working face 1-2 of the junction a of L-type spring supporting room 1-3 and curved working face 1-2 and the distance at sleeve 1 center and sleeve 1 center, rotate axle 2 when the curved working face 1-2 of sleeve 1 rotates towards far-end b place, roller 3 is mobile until locked to the curved working face b place of sleeve 1, and now isolator transmits torque;When rotating axle 2 and rotating around direction, a place, supporting surface side, roller 3 moves retrogressing and skids to the direction, curved working face a place of sleeve 1, now isolator slipping.
