[0006] The preloaded sleeve is provided with a plurality of inward clamping claw structures at the end of the sleeve body, and the inward clamping claw structures have a certain elasticity and can shrink or open in a small range according to the shaft diameter, so that the sleeve is in close contact with the shaft, thereby eliminating the fitting clearance between the sleeve and the shaft, and can effectively prevent the sleeve from shaking during operation, thereby ensuring the stability of the preloaded sleeve during operation.

[0007] Preferably, the sleeve body, the base and the plurality of inward-retracting clamping claw structures are an integrated structure. By arranging the sleeve body, the base and the plurality of inward-retracting clamping claw structures as an integrated structure, the structural strength of the preloaded sleeve can be improved, making it more durable.

[0008] Preferably, one end of the inner side of a plurality of the inward clamping claw structures is provided with the arc chamfer, and the radius of the arc chamfer is 0.2 mm.

[0009] Preferably, the width of several of the auxiliary grooves is 1 mm, the diameter of the sleeve body and the diameter of the base are both 14 mm, the outer diameter of the sleeve body is 16 mm, the outer diameter of the base is 22 mm, and the minimum distance between each two facing inward clamping claw structures is 13.8 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The preloaded sleeve is provided with a plurality of inward clamping claw structures at the end of the sleeve body, and the inward clamping claw structures have a certain elasticity and can shrink or open in a small range according to the shaft diameter, so that the sleeve is in close contact with the shaft, thereby eliminating the fitting clearance between the sleeve and the shaft, and can effectively prevent the sleeve from shaking during operation, thereby ensuring the stability of the preloaded sleeve during operation.
