Introduction
Sliding bearings, bearings that work under sliding friction. The sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, and friction loss and surface wear can be greatly reduced. The oil film also has a certain vibration absorption capacity. But the starting frictional resistance is relatively large. The part of the shaft supported by the bearing is called the journal, and the parts that match the journal are called the bearing bush. In order to improve the friction properties of the bearing pad surface, the anti-friction material layer cast on the inner surface is called the bearing liner. The materials of bearing bushes and bearing linings are collectively referred to as sliding bearing materials. Sliding bearing applications are generally under high-speed and light-load conditions.
Main feature
Commonly used sliding bearing materials include bearing alloys (also called Babbitt alloy or white alloy), wear-resistant cast iron, copper-based and aluminum-based alloys, powder metallurgy materials, plastics, rubber, hardwood and carbon-graphite, polytetrafluoroethylene (special Flon, PTFE), modified POM , etc.
The sliding bearing absorbs and transmits the force between the relative moving parts, and maintains the position and positioning accuracy of the two parts. In addition, the directional motion must be converted into rotary motion (such as reciprocating piston engine)
