Q:Which is good, rolling or sliding bearings?: The shaft supported by the bearing is called the journal, and the part that matches the journal is called the bush. In order to improve the friction properties of the bearing surface, the antifriction material layer, which is cast on its inner surface, is called the bearing lining. Bearing and bearing lining materials are collectively referred to as journal bearing materials. Sliding bearing applications are generally under low speed heavy load conditions, or maintenance and lubrication of the difficult parts of the operation.Generally, the rolling bearings consist of the outer ring, inner ring, roller and cage.

Q:What are the consequences of not hammer sliding bearing: The range of viscosity selection is L - ANl5 to L - AN68. High speed, big journal diameter bearings, oil viscosity can be lower, and conversely, oil viscosity should be a little higher.For machine tools, the sliding rails in general working conditions should be lubricated by mechanical oil. The viscosity of the oil shall be determined according to the magnitude, speed, horizontal or vertical temperature of the rail. Horizontal guideway should choose L - AN32 ~ L - AN68 viscosity of lubricating oil, and vertical guide rail should choose L - AN46 ~ L - ANl00 viscosity of lubricating oil.For gear transmission, the actual contact stress between the teeth are often very high, with each point on the tooth surface and the short time, but also engaged in sliding and rolling at the same time, therefore, the formation of liquid film is weak. The lubrication of gears depends mainly on the boundary oil film. The greater the gear load, the higher the viscosity of the selected oil; the higher the speed, the lower the viscosity of the selected oil; the higher the working environment temperature, the higher the viscosity of the selected oil. Under normal circumstances, the gear drive using L - AN46 viscosity of mechanical oil can meet the requirements.

Q:How does a sliding bearing move at work?: When sliding bearings work, sliding friction occurs; the magnitude of rolling friction depends mainly on the manufacturing accuracy; and the size of the sliding bearing friction depends mainly on the material of the sliding surface of the bearing. Plain bearings generally work with self lubrication functions; plain bearings are divided into non-metallic sliding bearings and metal sliding bearings in accordance with material.Sliding bearings (sliding, bearing) bearings that work under sliding friction.

Q:Plain bearings are linear bearings? Are they different?: Linear bearings are one of the rolling bearings, and the two are not the same concept at all.

Q:0 what are the friction states of plain bearings? What are the main differences between them?: 4. friction of relative motion.Above all need lubrication, can use Rongchang self-lubricating bearing, also belong to a kind of sliding bearing.Look at their movement patterns.

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:Why is the starting resistance of plain bearings high?: The rolling friction is actually a block rolling torque. When an object is rolling in the non smooth plane, if not by force or torque, its movement will gradually slow down, until still. Because objects and plane contact deformation. The object by gravity into the bearing surface, but also by the compression and deformation of the object itself, when the object is rolling forward, bearing surface uplift at the contact front, so the elastic object does not point to the axis and move forward.

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:I recently learned some knowledge of rolling bearings and journal bearings. Questions to ask the experts:1, sliding bearings for high speed, heavy load, then in reality, how many high speed, large load sliding bearings?2, in addition to the speed and load, rolling bearings and sliding bearings at the choice of, there are other considerations? Such as price.3, rolling bearings can withstand the maximum speed is generally how much? Such as 7000RPM or 10000RPM.Relatively superficial problem, may not ask the key point, but also ask you to forgive me, thank you!: There is an article entitled "how to choose the correct size of the bearing". I wonder if it will help you

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.
