- Q: What kinds of checks should be carried out for the design of non full liquid friction sliding bearings? Explain why, what does the PV value mean?
- PV is the product of a certain bearing and bearing in line speed conditions and the PV value is inversely proportional to the service life of the bearing;
- Q: where is it used in general, and some concrete examples are given
- Such bearings are generally called joint bearings, generally used in the direction of output force is not very stable at medium and low speed conditions, such as oil cylinders, hydropower stations, gates, automatic door closer. Solid bearings have the production of this product, you can consult.
- Q: What are the principles of plain bearings and plain bearings?
- Plain bearings refer to bearings that are free to slide in the axial direction and are free to move in radial direction. The structure of the sliding bearing consists of 4 layersA mixture of 1. PTFE and fiber 0.01~0.03mm can form a very good transfer film to protect the grinding shaft, providing the self-lubricating properties of the bearings.
- Q: High speed heavy duty important sliding bearing, bearing material with tin base bearing alloy or casting tin bronze?
- 2, lead base bearing alloy, suitable for low speed heavy load, the price is much cheaper than tin, but it is not suitable for high-speed. But the performance is better than that of copper alloy.
- Q: The service life of a sliding bearing can theoretically be infinite, but this is not necessarily the case because the conditions of use can not be ideal. I want to know how long the actual life of the sliding bearings is The longest sliding bearings that I have come into contact with are the bearings (dynamic lubrication) of two Japanese roller mill spindles, which have been used here for about 30 years without any repairs.
- Bearing life depends on the working environment, a lot of temperature.
- Q: What are the differences between rolling bearings and plain bearings?
- 4, for the same size of the shaft diameter, the rolling bearing is wider than the sliding bearing, so that the axial structure of the machine is compact;5, a high degree of standardization, mass production, consumption of lubricants less, easy to seal, easy to maintain, do not need to use non-ferrous metals, low cost.
- Q: What are the commonly used sliding bearing bushing materials
- (5) bearing alloy (Babbitt). It is an alloy of tin, lead, Li, antimony and so on. Has good abrasion resistance, but the intensity is low, the bearing can not be made individually, usually cast in iron and steel, Qingdao Steel Bearing base.(6) three layer load bearing materials. There are two kinds of composite materials: poly acrylic steel, ethylene steel body composite material and POM steel body composite material.
- Q: Generally speaking, the stiffness of the rolling bearings is more than the stiffness of the sliding bearings - the stiffness of the ball bearings is more than the stiffness of the roller bearings - -
- The same size of rolling bearings is lower than plain bearings, and the ball bearings are lower than those of roller bearings.
- 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 their respective priorities? Thank youThe sliding bearing is different from the rolling bearing, many categories, so many companies are doing the rolling bearing while passing sliding bearings, such as FAG; some do metal materials to sliding bearings, such as Japan datong. I hope the predecessors to enlighten.
