Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shaft sleeves, in particular to a shaft sleeve with a guiding function. Background Art
[0002] During long-term operation, the shaft neck surface is subjected to the extrusion force of the expansion sleeve and the combined mechanical force, which will cause permanent deformation and a diameter reduction of 0.1mm to 0.3mm. This in turn causes the mechanical expansion fit to fail to meet the required tightening force, resulting in a fit gap between the sleeve and the main shaft, causing wear of the sleeve. An existing patent for a shaft with a guiding function, patent publication number CN221541943U, includes a first shaft body, one side of which is mounted a sealing structure comprising a first sealing ring, a sealing ring, a first base, wear-resistant grooves, and a guide shaft. The first sealing ring is mounted on one side of the first shaft body, one side of the first shaft body is mounted a detachable structure, and one end of the first shaft body is mounted a replaceable structure. The utility model is provided with a detachable structure, and the detachable structure is provided with a first clamping ring and a second clamping ring. The first clamping ring and the second clamping ring are semicircular, and the other two shaft bodies are clamped to each other, so that the connection effect of the first shaft body and the second shaft body is better. The arc groove on the inner wall of the clamping ring more effectively enhances the overall strength of the clamping ring, making it less likely to deform. At the same time, the connecting structure is a bolt and a nut. This connection method is relatively firm and convenient to disassemble and assemble, thereby achieving the purpose of facilitating the disassembly of the shaft sleeve with a guiding function.
[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: when the sleeve is assembled, it needs to be combined with the rotating shaft, and a certain amount of wear will inevitably occur between the rotating shaft and the sleeve. If the sleeve is worn, it needs to be replaced manually, but manual disassembly and replacement will make it difficult to align the concentricity of the subsequent sleeve and the rotating shaft, which is inconvenient. Therefore, we proposed a sleeve with a guiding function to solve the above-mentioned problems. Utility Model Content
