Description

Technical Field

[0001] The utility model relates to the field of shaft sleeves, in particular to an assembly structure and an assembled shaft sleeve. Background Art

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft. As an important component of the sliding bearing, it plays a key role in the operation of the machine. The sleeve and the bearing seat generally adopt an interference fit, while the sleeve and the shaft adopt a clearance fit. However, during long-term operation, the sleeve will be subjected to the extrusion force of the expansion sleeve and the combined mechanical force, resulting in permanent deformation of the shaft neck surface, and the diameter reduction is usually between 0.1mm and 0.3mm. This deformation will further lead to a decrease in the mechanical expansion fit strength, and the expected tightening force cannot be achieved, resulting in a fit gap between the sleeve and the main shaft, thereby causing wear of the sleeve.

[0003] For the matching of the sleeve and the hole, the traditional assembly method usually adopts interference fit or transition fit, but this method often faces many challenges in actual operation. Since the sleeve and the hole on the component are often installed by hand or by hammering, not only is the installation process difficult, but it is also easy to damage the sleeve structure, affecting the service life and performance of the sleeve.
