Composite Bushings Are Widely Used For Sliding Parts Of Machinery
- Aug 16, 2017 -

The composite bushing is a composite bushing (MSB) made of steel plate as the base, middle sintered spherical bronze powder, surface rolled polytetrafluoroethylene (PTFE) and lead.

The composite bushing has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and no oil lubrication. The use of the product can reduce costs, reduce the mechanical volume, to avoid the phenomenon of bite the shaft and reduce the advantages of mechanical noise. Composite Bushings Products have been widely used in a variety of mechanical sliding parts, such as printing presses, lifts, textile machinery, fitness equipment, hydraulic trucks, micro-motor, solenoid valves, automobiles, Composite Bushings motorcycles and home machinery.

The composite bushing is composed of a main bushing and a sub-bushing, and the center of the bushing is provided with a bearing hole with a fixed barb on both sides. The main bushing center is provided with a bearing hole and a fixed elastic convex And a barb mounting hole corresponding to the fixed barb is provided at the other end, Composite Bushings and a fixed step is provided in the barb fitting hole to cooperate with the fixed barb. The utility model adopts two kinds of plastic bricks to make the composite bushing have two kinds of support, Composite Bushings can support a corresponding length of the shaft, for the structure requires compact (cantilever installation) friction torque requirements of low occasions.

The composite bushing contains a sleeve, the outer surface of which is spherical, with a flexible interlayer on the outside and a bearing on the outside of the flexible interlayer. The inner and outer surfaces of the flexible interlayer and the inner and outer surfaces of the bearing are also spherical, Composite Bushings with the sleeve and the flexible interlayer, and the flexible interlayer and the pad are bonded together. The outer circumference of the sleeve has a radially outer boss for retaining the flexible interlayer. This composite bushing, not only has the role of cushioning, damping, can reduce the mechanical noise, but also in the mechanism of reciprocating swing can be properly compensated, can improve the vehicle's handling performance and stability. It is suitable for ball joint connection in various mechanical equipment, especially for ball joint connection in vehicle suspension.
