Sliding bearing is a kind of friction bearing, according to its friction state can be divided into what?
Sliding bearings are suitable for high requirement or special requirements of the occasion, such as: (1) high speed, heavy load (2), (3) rotary precision is high, (4) under the huge impact and vibration, (5) bearing structure needs to be split, (6) the radial size small etc.. (2) rolling bearings, rolling bearingsThere are rolling bodies in the running, there is rolling friction in the bearing, and compared with the sliding friction, the rolling bearing friction coefficient and wear less.
The friction resistance of rolling bearings is small, and the load, rotation speed and work temperature are suitable for a wide range, and the standard partsA large number of special manufacturers, reliable quality, adequate supply, lubrication and maintenance convenience, but larger radial size, vibration and noise.As the mechanical efficiency of rolling bearings is higher, the maintenance of bearings is lower, so it is widely used in middle and low speed, as well as high precision requirements.
Bearings in accordance with the shaft and the form of friction between bearings, bearings can be divided into two categories: (1) sliding bearings, sliding bearings work, the shaft and bearings there is sliding friction. In order to reduce friction and wear, lubricant is often added to the bearings. The sliding bearing has the advantages of simple structure, small radial dimension, easy fabrication and easy installation, and has the advantages of stable operation, no noise, high impact resistance and strong bearing capacity, etc.. However, when the lubrication is poor, the sliding bearing will rapidly fail and the axial size will be larger.
