When the bearing ring 7 is installed inside the support ring 4, the plurality of sleeves 9 are located directly above the plurality of deformation grooves. Then, the sleeve 9 is pressed down, and the support ring 4 enters the inside of the deformation groove. At this time, the sleeve 9 is deformed through the deformation groove until the inner wall of the sleeve 9 is completely attached to the support ring 4, thereby achieving the purpose of fixing the bearing ring 7 inside the support ring 4.

[0033] The sleeve 9 is composed of a metal elastic material, and the sleeve 9 is composed of a metal elastic piece, which can improve the plastic deformation ability of the sleeve 9, make the sleeve 9 more easily connected and separated with the outer wall of the support ring 4 through the deformation groove, and improve the strength of the sleeve 9 and prolong the service life of the sleeve 9.

[0034] The sleeve 9 is bent, and the bending rate of the sleeve 9 is the same as that of the support ring 4, which can make the inner wall of the sleeve 9 more easily attached to the outer wall of the support ring 4, increase the contact area between the inner wall of the sleeve 9 and the inner wall of the support ring 4, prevent the sleeve 9 from falling off the support ring 4, and improve the tightness of the connection between the bearing ring 7 and the support ring 4.
