Description

Technical Field

[0001] The present invention relates to the technical field of fastening sleeves, and in particular to a fastening sleeve which is convenient for positioning on a shaft. Background Art

[0002] A shaft clamping sleeve is a device used to securely fasten various components to shafts and is widely used in the mechanical field. It generally consists of a sleeve body, fastening elements (such as bolts and nuts), and positioning elements (such as keys and pins). The sleeve body is usually cylindrical, with an inner diameter matching the outer diameter of the shaft, while the outer diameter is determined by the component to be mounted.

[0003] When the existing shaft fastening sleeve is in use, the shaft is easily deflected forward and backward along the axial direction during the rotation of the shaft in the bearing sleeve, generating pressure. Excessive pressure can cause mechanical damage to the fastening sleeve components, affecting the stability of the mechanical operation of the shaft. Moreover, in harsh environments, impurities such as dust, oil, and moisture can easily enter the fitting gap between the fastening sleeve and the shaft or other components, causing corrosion and wear of the fastening sleeve and the shaft. In addition, the fastening sleeve has been using traditional screw crimping fixing technology. The installation and disassembly process is time-consuming and labor-intensive, increasing the workload of assembly, operation and maintenance personnel. Summary of the Invention
