Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

As shown in figure 1, the one-way retainer and spring piece fixing structure comprises a retainer 1 and a needle roller 2, wherein a plurality of needle roller cavities 11 for inserting the needle roller 2 (see figure 3) are arranged at intervals in the circumferential direction of the retainer 1 through a partition plate 3.

As shown in fig. 1 and 2, a plurality of mounting portions 4 are provided on the outer side of the retainer 1, and the mounting portions 4 are located on the respective partition plates 3. The spring piece 5 is mounted on the mounting part 4, the spring piece 5 comprises a connecting piece 51 and elastic ends 52 obliquely fixed at two ends of the connecting piece 51, the two elastic ends 52 are arranged oppositely, a deformation part 53 is arranged in the middle of the connecting piece 51, and the shape of the deformation part 53 can be various, preferably omega-shaped and M-shaped. When the needle roller 2 is pressed towards the elastic end 52, the two ends of the connecting piece 51 are subjected to tensile force, so that stress is concentrated in the middle of the connecting piece 51, the connecting piece 51 is easier to break, and the deformation part 53 has elasticity, so that the elasticity of the connecting piece 51 can be increased, the tensile force of the two ends of the connecting piece 51 can be dispersed, and the service life of the spring piece 5 is prolonged.

as shown in fig. 2, the inclination angle between the resilient end 52 and the connecting piece 51 is 30 to 45 °, and the larger the inclination angle is, when the needle rollers 2 press the resilient end 52, the resilient end 52 is easily broken by the pressing of the needle rollers 2, thereby reducing the service life of the one-way bearing. The smaller the inclination angle is, the closer the distance between the two elastic ends 52 is, and the two ends of the needle roller 2 are easy to shake when the needle roller 2 contacts the elastic ends 52, so that the use effect of the one-way bearing is reduced.

as shown in fig. 2, an end of the elastic end 52 away from the connecting piece 51 is extended with a resisting portion 54, and the resisting portion 54 is parallel to the connecting piece 51. The abutting part 54 increases the contact area between the elastic end 52 and the needle roller 2, so that the needle roller 2 is more stable when rolling in the needle roller cavity 11, and the use effect of the one-way bearing is improved.

As shown in fig. 2, the distance between the opposite ends of the two elastic ends 52 is 2/3 times to 1/3 times the length of the connection piece 51, the sound generated when the one-way bearing uses friction can be reduced,

As shown in fig. 1, the mounting portion 4 includes end blocks 41 fixed to both ends of the separator 3 and a positioning block 42 provided between the two end blocks 41, and the end blocks 41 and the positioning block 42 are arranged in a staggered manner. When the spring piece 5 is mounted, the connecting piece 51 of the spring piece 5 is disposed between the end block 41 and the positioning block 42, that is, the elastic end 52 of the spring piece 5 faces the needle chamber 11, the side of the connecting piece 51 away from the elastic end 52 is abutted against the end block 41, the positioning block 42 is abutted against the side of the connecting piece 51 close to the elastic end 52, and the positioning block 42 is disposed at both ends of the deformation portion 53. The positioning block 42 and the end block 41 fix the spring piece 5, so that the spring piece 5 is not easy to move in the use process, and the stability of the spring piece 5 is improved.

the specific implementation process comprises the following steps:

When the one-way bearing is installed on the shaft, the roller pin 2 rotates in the roller pin cavity 11 and extrudes the elastic end 52, so that the two ends of the connecting piece 51 are stressed and stretched outwards, and the deformation part 53 is driven to deform, the deformation part 53 has elasticity, and can disperse the concentrated force at the two ends of the connecting piece 51, so that the connecting piece 51 is not easy to deform elastically, and the service life of the spring piece 5 is prolonged.
