Shaft sleeve
The sleeve is a cylindrical bushing that is sleeved on the shaft. It is widely used in various mechanical equipment. Its main function is to reduce friction and wear and improve the operating efficiency of the equipment. The following is a detailed introduction to the sleeve:
1. Basic definition of the sleeve
The sleeve is a sleeve on the propeller shaft or stern shaft and is a component of the sliding bearing. It usually adopts a clearance fit with the shaft and an interference fit with the bearing seat to ensure the stable operation of the shaft.
2. Composition and structure of the sleeve
The structure of the sleeve is relatively simple, mainly consisting of an outer cylindrical surface, an inner surface, a profile hole, two end surfaces, inner and outer step surfaces, inner and outer back grooves, and inner and outer chamfers. Among them, the inner hole is the supporting surface for supporting other parts and is also the main reference surface of the sleeve; the outer circle and its step surface are used to support other parts.
3. The main function of the sleeve
Reduce friction and wear: The sleeve can reduce the direct contact between the shaft and the bearing, thereby reducing friction and wear and extending the service life of the equipment.
Improve operating efficiency: By reducing friction, the sleeve can reduce the energy loss during the operation of the equipment and improve the overall operating efficiency.
Protect the shaft and bearings: The sleeve acts as a buffer layer between the shaft and the bearing, which can prevent damage to the shaft and the bearing caused by direct contact.
4. Installation and fixation of the sleeve
When installing the sleeve, it is necessary to ensure that the size of the sleeve matches the size of the shaft and the bearing to avoid too tight or too loose fit. The sleeve can be fixed to the shaft end in the form of a circlip, adding a circlip groove at both ends of the sleeve, and then using the circlip to fix the sleeve.
5. Maintenance and care of the sleeve
During long-term operation, the sleeve may be subjected to the extrusion force of the expansion sleeve and the composite mechanical force, resulting in permanent deformation or wear. Therefore, it is necessary to regularly inspect and maintain the sleeve, and replace the severely worn sleeve in time to ensure the normal operation of the equipment.
