A mechanical shaft sleeve is a mechanical part. It is a cylindrical object that fits on the rotating shaft and is a component of a sliding bearing. The main function of the sleeve is to reduce the wear of the shaft and the seat, fix the position, bear the load, and protect the shaft from wear and corrosion. The sleeve and the bearing seat usually have an interference fit, while the sleeve and the shaft have a clearance fit. When designing and manufacturing the sleeve, factors such as its dimensional accuracy, surface roughness, hardness and wear resistance need to be considered. The structural design methods and techniques of the sleeve include selecting the appropriate shape, size and material, as well as ensuring sufficient strength and rigidity. The manufacturing process and quality control of the industrial sleeve include steps such as casting, forging, machining and heat treatment to ensure that the quality of the sleeve meets the requirements of use.
