Reinforcing sleeve for bearing

Abstract

This utility model discloses a reinforcing sleeve for bearings, comprising an inner cylinder and an outer cylinder. A set of reinforcing ribs are distributed and installed on the surface of the inner cylinder, and a set of strip-shaped grooves are distributed on the inner wall of the outer cylinder. Each reinforcing rib is assembled into each strip-shaped groove. An end cap is provided at the port of the inner cylinder. The inner cylinder and the outer cylinder are assembled together. The advantages of this utility model are: by assembling the inner cylinder inside the outer cylinder, and simultaneously assembling the reinforcing ribs distributed on the inner cylinder with the strip-shaped grooves distributed on the inner wall of the outer cylinder, the sleeve's resistance to deformation is strengthened, and the axial rotational force between the inner and outer cylinders can be offset. Furthermore, the end caps installed at the corresponding ports of the inner cylinder serve both as dust prevention and as a restriction on the bearing's installation position within the inner cylinder.

Description

Technical Field

[0001] This utility model relates to the field of bearing sleeves, specifically a reinforcing sleeve for bearings. Background Technology

[0002] Bearing sleeves are a crucial basic component in mechanical transmissions, supporting rotating parts through sliding friction and reducing friction and wear. Currently, existing bearing sleeves are made of the same material and have limited structural performance, which is not conducive to strengthening the structural strength of the bearing sleeve and increases the risk of deformation. Therefore, a reinforced bearing sleeve is proposed to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a reinforcing sleeve for bearings in order to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a bearing reinforcing sleeve, comprising an inner cylinder and an outer cylinder, wherein a set of reinforcing ribs are distributed and installed on the surface of the inner cylinder, and a set of strip grooves are distributed on the inner wall of the outer cylinder, wherein each reinforcing rib is assembled in each strip groove, and an end cap is provided at the port of the inner cylinder, wherein the inner cylinder and the outer cylinder are assembled together.

[0005] In a further technical solution, threaded structures are provided on the inner walls of both ends of the inner cylinder.

[0006] In a further technical solution, the annular surface of the end cap is provided with a threaded structure, and a circular hole is provided in the middle of the end cap.

[0007] In a further technical solution, the diameter of the circular hole is larger than the diameter of the bearing inner ring.

[0008] In a further technical solution, the strip groove is inclined to the inner wall of the outer cylinder.

[0009] Compared with the prior art, the advantages of this utility model are as follows: by assembling the inner cylinder inside the outer cylinder, and assembling the reinforcing ribs distributed on the inner cylinder together with the strip grooves distributed on the inner wall of the outer cylinder, the deformation resistance of the sleeve is strengthened, and the axial rotational force between the inner cylinder and the outer cylinder can also be offset. At the same time, the end cap is installed in the port of the corresponding end of the inner cylinder, which can not only play a role in dust prevention, but also limit the installation position of the bearing inside the inner cylinder.

Therefore, they should not be construed as limitations on this utility model.

[0017] Please see Figure 1-2 As shown, a bearing reinforcing sleeve includes an inner cylinder 1 and an outer cylinder 3. A set of reinforcing ribs 2 are distributed and installed on the surface of the inner cylinder 1. A set of strip grooves 310 are distributed on the inner wall of the outer cylinder 3. Each reinforcing rib 2 is assembled in each strip groove 310. An end cap 4 is provided at the port of the inner cylinder 1. The inner cylinder 1 and the outer cylinder 3 are assembled together. The strip grooves 310 and the inner wall of the outer cylinder 3 are inclined.

[0018] The inner walls of both ends of the inner cylinder 1 are provided with threaded structures.

[0019] The annular surface of the end cap 4 is provided with a threaded structure, and a circular hole 410 is provided in the middle of the end cap 4. The diameter of the circular hole 410 is larger than the diameter of the inner ring of the bearing.

[0020] Compared with the prior art, the difference of this utility model is that by assembling the inner cylinder 1 inside the outer cylinder 3, and assembling the reinforcing ribs 2 distributed on the inner cylinder 1 together with the strip grooves 310 distributed on the inner wall of the outer cylinder 3, the deformation resistance of the sleeve is strengthened, and the axial rotational force between the inner cylinder 1 and the outer cylinder 3 can also be offset. At the same time, the end cap 4 is installed in the port of the corresponding end of the inner cylinder 1, which can not only play a role in dust prevention, but also limit the installation position of the bearing inside the inner cylinder 1.
