Sliding bearings are also widely used, such as printing presses, textile machines, tobacco machinery, micro motors, cars, motorcycles, dry bearings and agricultural machinery and so on. Sliding bearings have their own advantages and features.
1, oil-free smooth or less oil smooth, suitable for oil or difficult to refuel sliding composite bearing site, can be used in the conservation or less conservation.
2. The sliding bearing has good wear resistance, low friction coefficient and long service life.
3, there is appropriate elastic-plastic, can stress, sliding bearing, copper alloy sleeve on a wider touch surface, improve the bearing capacity.
4, static and dynamic friction coefficient near, can eliminate the crawl at low speed, and then ensure the accuracy of mechanical work.
5, can make the machine reduce vibration, reduce noise, avoid pollution, improve working conditions.
6, the sliding bearing in the operation process can form a transport membrane, play a maintenance effect on the grinding shaft, no bite axis phenomenon.
7, sliding bearings on the hardness requirements of the grinding shaft low, without hardening and tempering of the shaft can be used, and then reduce the processing difficulty of the parts.
8, thin-walled structure, light weight, can reduce the mechanical volume.
9. The steel can be plated with a variety of metals. It can be used in corrosive media. Now it has been widely used in various mechanical sliding parts, for example:
Printing presses, textile machines, tobacco machinery, micro motors, cars, motorcycles and agricultural and forestry machinery, etc..
