description

The shaft sleeve is a cylindrical mechanical part sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the shaft sleeve and the bearing seat adopt an interference fit, and the shaft adopts a clearance fit. Shaft sleeve refers to the sleeve on the propeller shaft or stern shaft. The bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. The similarity between the sleeve and the bearing is that both bear the load of the shaft. The difference between the two is that the shaft sleeve is an integral structure, and the shaft and the shaft sleeve move relative to each other when rotating; while the bearing is a split type, the inner and outer rings of the bearing itself move relative to each other when rotating. But in essence, the sleeve is actually a kind of sliding bearing. The bearing bush is equivalent to the outer ring of the sliding bearing. The bushing is integral and moves relative to the shaft, while some of the bearing bushes are split and rotate relative to the shaft. In the LEGO Mindstorms series and BioTrans RoSys series robot components, the shaft sleeve refers to the silver-grey Lego standard shaft holder, which is divided into full shaft sleeve and 1/2 shaft sleeve. During the long-term operation of the shaft sleeve, the surface of the shaft journal is subjected to the squeezing force of the expansion sleeve and the composite mechanical force, which will cause its permanent deformation, and its diameter may be reduced by 0.1mm~0.3mm. As a result, the mechanical expansion and tightening force cannot reach the required tightening force, and a matching gap appears between the shaft sleeve and the main shaft, which causes the wear of the shaft sleeve. The latest repair method Due to the high value of components, traditional repair methods are more expensive. With the development of advanced technologies such as foreign polymer composite materials, some repair methods that are fast and low-cost are favored. This method has also been introduced in the country, and the more mature Blessed World Blue 2211F material, etc. The material has comprehensive mechanical properties unmatched by traditional methods, excellent adhesion and temperature resistance and corrosion resistance. The maximum compressive strength can reach 1200kg/cm2, and the adhesion (overlapping shear tensile test) on a smooth steel surface is 225 kg/cm2. Therefore, it can be used to repair the wear and tear of large shaft sleeves. And the equipment does not need to be disassembled on a large scale, saving a lot of manpower and material resources for the enterprise.
