Q:The commonly used sliding bearing materials are divided into metal materials and which two materials
Metal materials and non-metallic materials, non-metallic materials, and engineering plastics, carbon graphite, rubber, wood, metal materials, sub bearing alloy, copper alloy, aluminum base bearing alloy, cast iron, porous metal materials
Q:What are the advantages and disadvantages of plain bearings compared with those of rolling bearings?
Disadvantages of plain bearings:1) the friction coefficient is large, and the power consumption is too much.2) not suitable for mass production, interchangeability is not good, it is not easy to install, disassemble and repair.3) the internal clearance is big, the processing precision is not high.4) low transmission efficiency, large heat consumption, inconvenient lubrication and maintenance, consumption of lubricant.5) the load, the speed and the working temperature have a narrow range of adaptation, and a small change in the working conditions will greatly affect the performance of the bearings.6) can not bear radial and axial load simultaneously.Plain bearings: bearings that work under sliding friction. Plain bearings are stable, reliable and noiseless. They are used under low speed, light load or intermittent working conditions.
Q:Can the sliding bearings move in axial direction?
Yes, but it seems that the contact surface has changed, and the surface contact will not be the same as in the original position.
Q:What are the types of plain bearings?
According to the bearing materials can be divided into bronze bearings, cast iron bearings, plastic bearings, stone bearings, powder metallurgy bearings, self-lubricating bearings and oil bearing.According to the bearing structure can be divided into round, elliptical bearing, bearing three oil blade bearing, the stepped surface bearing and tilting pad bearings and foil bearings etc..
Q:Bearing is the bearing?
No, bearing is with a bearing shell and a mounting hole, sliding bearing, it has become a linear bearing
Q:Sliding bearings and rolling bearings of the same point and different points 10
Plain bearings, usually made of bronze or Babbitt, have heavy duty characteristics and require a standing lubrication system to provide lubrication. Light load can be lubricated by powder metallurgy.Ball bearings are usually made of ball bearing steel, which is lubricated with grease and requires regular replacement of the grease. Rolling bearings usually can bear some axial force, but the sliding bearings do not have this function.
Q:Can I use plain bearing in high temperature environment?
The vacuum environment, is expected to 200 degrees temperature, want to use the sliding bearing, mainly on account of the small space, the environment is not suitable for sliding bearing, sliding bearing can be at a temperature of about 200 degrees, but the high temperature expansion, easy to get stuck.
Q:What are the two types of friction lubrication in plain bearings?
(3) non liquid friction sliding bearing calculation and checking, limit pressure P, to ensure that the lubricating oil film is not destroyed; limit value of PV, in order to ensure the bearing temperature is not too high, because the temperature is too high, easy to cause the rupture boundary of oil film.(4) according to the principle of hydrodynamic lubrication, the hydrodynamic lubrication sliding bearing is designed, which is mainly used in the continuous high speed operation.
Q:For sliding bearing, bearings, bushings, bushing and difference function
Sliding bearing comprises a bearing, bushings, bushing, the bushing is split off, mainly used for crankshaft bearing, the other is a circular sleeve shaped.
Q:Is the belt drive suitable for plain bearings?
