- Q: What copper is used to produce plain bearings for machine tools?
- Self lubrication copper sleeve sliding bearing for machine tool, which is based on high strength copper alloy (CuZn25Al5, CuZn24Al6Fe3Mn4) as the basic material,
- Q: On what occasions are plain bearings used?
- 3, heavy load occasions;4, under the condition of tremendous impact and vibration;5, need to be made into split bearing occasions;
- Q: One hundred and twentyAttention is the reason and purpose, the postgraduate entrance examination urgent need, thank you answer, after the exam will be re points, thank you!
- Objective: the heat balance calculation is designed to limit the inlet temperature of the lubricant so as to ensure the normal operation of the sliding bearings
- Q: 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.
- Q: Advantages and disadvantages of plain bearings relative to rolling bearings
- Advantages of plain bearings:1, and rolling bearings of the same volume of load capacity is much greater.2, vibration and noise is small, used in high precision requirements, but also does not allow vibration occasions.3, the metal foreign body caused little impact, it is not easy to produce early damage.Well, summed up the shortcomings of many advantages less, but in different use occasions, sliding bearing performance is very prominent! QQ 1054839354 is willing to share the bearing knowledge for you!
- Q: I need to use thrust bearings in the design, and the shaft is vertical. What should I use for this bearing? How should the structure be designed?
- LZ put it in detail and write down the actual conditions. Otherwise, I'll recommend all of the thrust bearings to you.
- Q: When calculating non liquid friction sliding bearings, what is the purpose of checking P, PV, v?
- Because for non liquid friction sliding bearings, in order to make the bearing area fully lubricated, sometimes it is better to sacrifice part of the bearing area, and extend the oil tank to or directly into the load area.
- 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.

- Q: What is the effect of clearance on sliding bearings?
- 1, the gap between bearings and bearings.2, bearings radial series gapThe first kind of clearance will cause the bearing or bush to be damaged, and the lubrication oil pressure will be reduced. The gap is too small, which will make the bearing or bearing load increase sharply and even burn (tile)The second kind of clearance is too big, the bearing will move back and forth in the radial direction, the whole machine is not stable, the gap is too small, so that the load of the machine increases
- Q: In power plants, are the bearings used in turbines rolling or plain bearings?
- Is the bearing type alloy sliding bearing, high precision, strong stability, high bearing capacity, easy to assemble and maintain!
