Abstract

A bearing rotor component structure comprises a shaft, a first bearing and a second bearing, wherein the first bearing and the second bearing are sleeved on the left side and the right side of the shaft; glue layers are arranged between the outer rings of the first bearing and the second bearing and the shaft sleeve; a spring is arranged between the first bearing and the second bearing; a clamp spring and a washer I are sequentially arranged between the spring and the outer ring of the bearing I, and the outer ring of the clamp spring is clamped with the inner side of the shaft sleeve; a second washer and a rubber pad are sequentially arranged between the spring and the outer ring of the second bearing; the first gasket, the second gasket and the rubber pad are all sleeved on the shaft. Compared with the prior art, the bearing rotor component structure of the utility model has the advantages that the polyurethane adhesive layer is arranged between the shaft sleeve and the bearing outer ring, so that the adhesive layer plays the roles of buffering and fixing the bearing, and the axial bearable push-out force is more than 500N after the double bearings are fixed; the rubber layer can also play a role in vibration reduction, so that the noise of the whole rotor assembly is reduced by about 10 dB.

Description

Bearing rotor assembly structure

Technical Field

The utility model relates to a bearing equipment technical field specifically indicates a bearing rotor subassembly structure.

Background

The bearing is an important part in the modern mechanical equipment, and has the main functions of supporting the mechanical rotating body, reducing the friction coefficient in the movement process of the mechanical rotating body and ensuring the rotation precision of the mechanical rotating body; the interference fit of bearing fixes the position of bearing among the prior art, and middle spring extrudees toward both sides, causes the bearing inner race to appear the extrusion scar easily, and whole subassembly noise is big.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide a bearing rotor subassembly structure.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a bearing rotor component structure comprises a shaft, a first bearing and a second bearing, wherein the first bearing and the second bearing are sleeved on the left side and the right side of the shaft; glue layers are arranged between the outer rings of the first bearing and the second bearing and the shaft sleeve; a spring is arranged between the first bearing and the second bearing; a clamp spring and a washer I are sequentially arranged between the spring and the outer ring of the bearing I, and the outer ring of the clamp spring is clamped with the inner side of the shaft sleeve; a second washer and a rubber pad are sequentially arranged between the spring and the outer ring of the second bearing; the first gasket, the second gasket and the rubber pad are all sleeved on the shaft.

Furthermore, the thickness of the adhesive layer is less than 0.02mm, and the deformation of the adhesive layer after being stressed is between 0.005 and 0.01 mm.

Further, the glue layer is a polyurethane glue layer.

Furthermore, the first bearing and the second bearing are connected with the shaft in an interference fit mode.

Compared with the prior art, the bearing rotor component structure of the utility model has the advantages that the polyurethane adhesive layer is arranged between the shaft sleeve and the bearing outer ring, so that the adhesive layer plays the roles of buffering and fixing the bearing, after the single bearing is fixed through the adhesive layer, the axial bearable thrust force is more than 200N, and after the double bearings are fixed, the axial bearable thrust force is more than 500N; the rubber layer can also play a role in vibration reduction, so that the noise of the whole rotor assembly is reduced by about 10 dB; in addition, the bearing is limited in the shaft sleeve through the clamp spring, so that the bearing is prevented from axially moving in the shaft sleeve, a rubber pad is additionally arranged between the bearing and the gasket, the rubber pad plays a role in damping, the end face of the bearing is guaranteed to be evenly stressed, and the bearing cannot be inclined in the shaft sleeve.
