- Q: The unit has to take out a review question and answer questionHow should emergency handling of engine pump sliding bearings cause heating and smoke?Who knows how to answer one of the troubles?,Then ask a question, generally speaking, sliding bearings, heating, smoke, what are the ways to deal with it, there are known to say, I sum up, good answer
- Brother, I did 14 years of mechanical maintenance, sliding bearings, heating, smoke, the most urgent treatment: 1. emergency shutdown. The sliding bearing heating smoke indicates that the clearance between the sliding bearing and the shaft is too tight, or that the grease / grease has impurities (metal scraps) and other things, and that it may be that the bearings have reached the service life and damaged. Maintenance may cause damage to the shaft if it is not shut down, so maintenance costs will be higher. 2. disassemble and repair the pump. Check what causes heat, smoke, cooling is a temporary solution, not only the pump will also heat, and may damage the whole pump. For example, check the running of the bearings, whether there is a deep scratch, or whether the shaft is worn, whether there is a foreign body. After confirming the cause, proceed "the right remedy"".
- Q: while the automobile wheel shafts and reducer gears use rolling bearings?
- The crankshaft is easy to produce axial movement, often need correction of axial clearance so sliding bearings, gears and gear box has basically not axial (produces radial runout), so the gear box are generally used in high quality of rolling bearing!
- Q: What are the requirements for the material performance of plain bearings?
- When the machine does not work, the axle is resting on the bearing and exerts pressure on the bearing. When the shaft rotates at a high speed, the shaft to the bearing with periodically varying load, sometimes accompanied by shock.
- Q: What are the requirements for the structure and properties of plain bearing materials and what are the materials used?
- [organization]: the bearing alloy should have the ideal organization of both hard and soft: (1) soft matrix and uniformly distributed hard point (2). Soft particles are distributed on the hard matrix. When the bearing is working, the soft tissue is firstly worn down and sunken, and the lubricant can be stored to form a continuous distribution of oil film, while the hard component plays the role of supporting the journal. Thus, the actual contact area of the bearing and the shaft neck is greatly reduced, so that the friction of the bearing is reduced.
- Q: What are the conditions for forming sliding bearings and dynamic oil film lubrication?
- Conditions for lubrication of hydrodynamic oil film for sliding bearings:1, must have an oil wedge to form a dynamic pressure, to ensure equal access to oil;2, the thrust plate relative motion to form convergent wedge on the pad;3, the viscosity of the oil is right, the amount of oil appropriate.
- Q: What are the types of plain bearings?
- There are many kinds of sliding bearings. According to the direction that can bear load, can be divided into radial (Xiang Xin) sliding bearings and thrust (axial) sliding bearings two categories.
- Q: What is the relationship between the eccentric e of the sliding bearing and the external load and the bearing speed?
- The bigger the external load is, the lower the bearing speed is, and the smaller the offset e is
- Q: What will cause the friction coefficient to be inaccurate in a hydrodynamic sliding bearing?
- The gap between the shaft and the hole, the shaft speed of these two factors is more critical, gap control is not good, there is no way to form a good oil film, that is, can not form a complete liquid friction
- Q: For sliding bearing, bearings, bushings, bushing and difference function
- The bushing is mounted on the shaft, with the shaft to rotate together. The Bush is mounted on the seat and does not rotate.There are many large shaft to achieve part of high hardness and high wear resistance with the invention and bearing bushes, but since a high frequency quenching and surface treatment process after these basically eliminated.
- Q: What are the advantages and disadvantages of plain bearings and rolling bearings?
- 4. thrust plain bearings (understood)(1) the thrust bearing fixed and tilting.(2) the thrust surface of thrust bearing can use the end face of the shaft, or can make a convex shoulder or thrust the disc in the middle of the shaft(two) types and characteristics of rolling bearings1. classification of rolling bearingsAccording to the shape of the rolling body is divided into: ball bearings, roller bearings2. characteristics of rolling bearings(1) advantages:Compared with plain bearings, rolling bearings have the advantages of small frictional resistance, quick starting, high efficiency, simple lubrication and easy replacement(2) shortcomings:Poor impact resistance, high speed noise, less working life than liquid lubricated sliding bearings
