Description

Technical Field

[0001] The utility model relates to the technical field of bushings, in particular to a conveyor belt bushing which is convenient to replace. Background Art

[0002] The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing and wear protection. It refers to a ring sleeve that acts as a gasket. When the conveyor belt is used, it is easy to cause wear of the parts due to long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, it is necessary to select a material with lower hardness and better wear resistance for the sleeve or bushing, which can reduce the wear of the shaft and the seat. When the sleeve or bushing is worn to a certain extent, it is replaced, which can save the cost of replacing the shaft or seat. Generally speaking, the bushing and the seat adopt an interference fit, but the existing bushing has poor protective performance during use, resulting in a reduced service life of the bushing, resulting in the need for frequent replacement.
