[0030] Example 1
[0031] This application discloses an anti-loosening bearing. (Refer to...) Figures 1-3 It mainly includes a bracket 1 and a bearing body 2. The bracket 1 has a through hole 11, and the two ends of the mounting hole 11 are provided with assembly grooves 12 that are adapted to the bearing body 2. A circumferential limiting structure is provided between the bearing body 2 and the inner wall of the assembly groove. An axial limiting structure is provided between the groove opening of the assembly groove 12 and the bearing body 2.
[0032] In actual use, the circumferential limiting structure restricts the radial position of the bearing body 2, which can reduce the occurrence of the bearing body 2 rotating and shifting in the assembly groove 12; the axial limiting structure restricts the position of the bearing body 2 in the axial direction, which can prevent the bearing body 2 from sliding in the assembly groove 12 or even sliding out of the assembly groove 12.

The positioning pin 3 is restricted between the first half groove 21 and the second half groove 13. The part of the positioning pin 3 embedded in the first half groove 21 can restrict the position of the bearing body 2, which can prevent the bearing body 2 from rotating in the assembly groove 12 and realize the circumferential positioning of the bearing.
[0035] Reference Figure 1 and Figure 3 The outer rounded corner of the bearing body 2 near the groove opening of the assembly groove 12 is formed with a chamfered bevel 22, which is set inward in the direction away from the assembly groove 12; the axial limiting structure includes a plurality of limiting protrusions 18 located on the inner wall of the groove opening of the assembly groove 12, which are evenly arranged in a circumferential array on the outer wall of the chamfered bevel 22; the two sides of the bearing body 2 are limited between the limiting platform 14 and the plurality of limiting protrusions 18.

[0037] It should be noted that in this embodiment, several limiting protrusions 18 are integrally pressed into shape by pressing tool 4.

When the bearing is installed in the assembly groove 12, the six spikes 41 on the pressing fixture 4 can be inserted into the end face of the bracket 1 by hydraulic equipment. The spikes 41 are pressed into the end face of the bracket 1, which can deform the inner wall of the assembly groove 12 on the bracket 1 and bulge inward to form six limiting protrusions 18.
[0039] It should be noted that during the actual assembly process, the number of tapered holes 17 can be adjusted to adjust the number of limiting protrusions 18 according to the actual needs of use, so as to meet different limiting requirements. This will not be limited or elaborated here.
