Steel Inch Reducing Bushing Wheel Metal Fittings Reducing Bushing Adapters.

Description

The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc. It refers to the ring sleeve that functions as a gasket. In the field of valve applications, the bushing is inside the valve cover, and corrosion-resistant materials such as polytetrafluoroethylene or graphite are generally used for sealing.

The bushing generally acts as a sliding bearing. In order to save material, the wall thickness of the bushing is designed according to the shaft load required by the bearing. Generally, cast copper and bearing alloy materials are used. The shaft sleeve is divided into open and non-opened, which depends on the needs of the structure. Generally, the shaft sleeve cannot bear the shaft load, or can only bear a small axial load. Or add thrust bearing.

In the moving parts, the wear of the parts is caused by long-term friction. When the gap between the shaft and the hole is worn to a certain extent, the parts must be replaced. Therefore, the designer chooses the lower hardness and better wear resistance when designing. The material is the shaft sleeve or the village sleeve, which can reduce the wear of the shaft and the seat. When the shaft sleeve or the village sleeve is worn to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat. Generally speaking, the bushing and the seat are made of Interference fit, and clearance fit with the shaft, because no matter what, it is unavoidable to avoid wear and tear, and can only prolong the life, and shaft parts are relatively easy to process.
