- Q: What's the connection between the crankshaft and the sliding bearings?
- The crankshaft is the shaft, the Bush is tile, the upper and lower two pieces of tile and together is the sliding bearing, can serve as the support of the crankshaft.
- Q: What are the structural and functional differences between thrust bearings and radial bearings and conventional ball bearings and plain bearings?
- First of all, there is a classification error in the question you ask. The thrust bearings and radial bearings are separated according to the direction of the bearing force of the shaft. The ball bearings and the sliding bearings are separated according to the bearing structure,
- Q: What are the advantages and disadvantages of plain bearings compared with those of rolling bearings?
- (1) types and characteristics of plain bearings1. the sliding bearings are divided according to the load:(1) radial sliding bearing (radial sliding bearing), mainly bearing radial load;(2) thrust bearings are mainly subjected to axial load.2. sliding bearings are suitable for low speed, high precision, heavy load and structural requirements. It is also used at low speed and impact.3. center journal bearing(1) integral type and split fractionThe splitting is usually made up of bearing cap, bearing seat, bearing bush and connecting bolt.(2) the Bush is the key part in the bearing.Bearing materials should have small coefficient of friction, good thermal conductivity, small coefficient of thermal expansion, wear resistance, corrosion resistance, strong adhesive resistance, sufficient mechanical strength and plasticity.(3) requirements for bearing materials: bearing alloy (Babbitt), bronze, bearing materials of special properties, etc..4. thrust plain bearings (understood)(1) the thrust bearing fixed and tilting.(2) the thrust surface of thrust bearing can use the end surface 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 bearings.2. 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:Low impact resistance, noise at high speed, and less working life than liquid lubricated sliding bearings.
- Q: Material and allowable line speed of plain bearings?
- Bushings in oil lubrication and oil-free lubrication, large load, and load hours allowed line speed is not the same. As the first floor said, the design of such bearings, not only depends on the V value (line speed), but also depends on the P value (load), and the PV value. Generally, the wire speed of copper alloy is about 0.5M/S.
- Q: National standard for plain bearings
- Multilayer metal bearing materials bearing sliding bearing test of 24 GB/T23894-2009 copper alloy inlaid solid lubrication bearing 25 GB/T23892.2-2009 sliding bearings under steady-state conditions of fluid dynamic pressure of tilting pad thrust bearings - Part second: tilting pad thrust bearing fluid check calculation function 26 GB/T23892.1-2009 sliding bearings under steady-state conditions of dynamic pressure of tilting pad thrust bearings - Part first: tilting pad thrust the bearing calculation of 27 GB/T2 3892.3-2009 sliding bearings under steady-state conditions of fluid dynamic pressure of tilting pad thrust bearings - Part third: Calculation of tilting pad thrust bearings allowableness fluid 28 GB/T23891.1-2009 sliding bearings under steady-state conditions of dynamic pressure thrust bearing thrust bearing part first: computational fluid 29 GB/ T23891.2-2009 sliding bearings under steady-state conditions of dynamic pressure thrust the second part: bearing thrust bearing calculation function 30 GB/T23891.
- Q: Failure forms of plain bearings, failure forms of plain bearings
- 5. corrosion: oxidation of lubricant to acid substance corrosion.
- Q: Effect of bearing speed on oil film stiffness of journal bearings
- The shaft and bearings are in direct contact. Is there an oil film at this time?! It is true that the eccentricity decreases and the stiffness decreases. But in the front, it depends.
- Q: it is better to have pictures of 6000V motors at both ends of the bearing what is called?
- Rolling bearings, whether ball bearings or roller bearings, in the absence of load point contact, sliding bearings are surface contact, and no relative movement, in short, a lot
- Q: Tilting pad radial sliding bearing which features
- The lubricating oil from the gap between each pad into the bearing, from both ends of seal bearing ring hole discharge. If you ignore the effect of pad inertia, friction force and the oil film shearing force of internal friction fulcrum, each pad to the axial diameter of the oil film force is always through the center shaft, the rotor movement in bearings only, will not have a leading axis
- Q: Fan relatively loud, on-line check found that rolling bearings are best not to oil, sliding bearings can be oiled.I was depressed, I do not know what the fan is bearing.. in fact, the whole hardware blind.Which prawns can say that? It's better to compare the pictures above.. ThanksYes, the video card fan is too loud.. Considering changing?..Originally, I had only a heat sink.. Nothing, but the temperature is too high and the recent game fan.Had to buy 30 yuan. Because of the rush to buy.. The size is not found. The quality is so bad.. A small fan, mounted on a radiator.. My other fans don't have any problems.
- Did you buy the computer to make any request for the cooling fan? Or let him handle it for you?Most of them are regular fans, but according to my experience, the gas has improved significantly, but it will be back in one or two months, so you should probably change the fanIs your fan not stable and cause resonance to make noise? 30 yuan, though not much, should not be so bad
