Plain bearings are widely used, such as textile machines, printing machines, automobiles, tobacco machinery, micro-motors, motorcycles, agricultural and forestry machinery, etc. Plain bearings also have their characteristics and advantages.
1. It can reduce the vibration and noise of machinery, prevent pollution and improve working conditions.
2. It has a proper amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity of the bearing.
3. Plain bearings have good wear resistance, a small friction coefficient, and long service life.
4. The static and dynamic friction coefficients are similar, which can eliminate crawling at low speeds, thereby ensuring the working accuracy of the machine.
5. No oil lubrication or less oil lubrication, suitable for places where refueling is impossible or difficult to refuel, and no maintenance or less maintenance can be used during use.
6. The plain bearings can form a transfer film during operation, which can protect the grinding shaft and prevent the shaft from biting.
7. Plain bearings have low requirements on the hardness of the grinding shaft, and the shaft without quenching and tempering treatment can be used, thus reducing the processing difficulty of related parts.
8. Thin-wall structure, lightweight, can reduce mechanical volume.
9. The back of the steel can be electroplated with various metals, and can be used in corrosive media; it has been widely used in sliding parts of various machines, such as:
Tobacco printing machinery, micro motors, brushing machines, textile machines, automobiles, motorcycles and agricultural and forestry machinery, etc.
