AI Technical Summary
Technical Problem
The existing bearing sleeve has a one-sided structural performance, resulting in insufficient strength and increasing the risk of deformation.
Method used
Design a reinforced sleeve structure including an inner cylinder and an outer cylinder. The inner cylinder has reinforcing ribs distributed on its surface, and the inner wall of the outer cylinder has a strip groove. After the inner and outer cylinders are assembled, the reinforcing ribs match the strip groove. The inner cylinder port is provided with an end cap to enhance structural strength and dustproof function.
Benefits of technology
It improves the sleeve's resistance to deformation, counteracts axial rotational forces, and effectively prevents dust and restricts the bearing's installation position.

Abstract
The reinforcing sleeve for the bearing comprises an inner cylinder and an outer cylinder, a group of reinforcing ribs are distributed and installed on the surface of the inner cylinder, a group of strip-shaped grooves are distributed and formed in the inner wall of the outer cylinder, each reinforcing rib is assembled in the corresponding strip-shaped groove, an end portion round cover is arranged at a port of the inner cylinder, and the end portion round cover is matched with the end portion round cover. The inner cylinder and the outer cylinder are assembled together. The sleeve has the advantages that the inner sleeve is assembled in the outer sleeve, meanwhile, the reinforcing ribs distributed on the inner sleeve and the strip-shaped grooves distributed in the inner wall of the outer sleeve are assembled together, the deformation resistance strength of the sleeve is enhanced, the axial rotation acting force existing between the inner sleeve and the outer sleeve can be offset, and the service life of the sleeve is prolonged. Meanwhile, the end round cover is installed in the port of the corresponding end of the inner cylinder, so that the dustproof effect can be achieved, and the installation position of the bearing in the inner cylinder can be limited.
