Q:Is the high or low pair of plain bearings and shafts?: Since the contact area is surface contact, the sliding bearings and shafts are low pairs

Q:What is the axial series momentum of plain bearings?: Rolling bearings are widely used in various machines and institutions because of their small friction resistance, quick start-up, high efficiency, high rotating accuracy, simple lubrication and easy assembly and disassembly. Rolling bearings are standard parts, which are produced by the bearing factory in large quantities, and the designers can choose them directly according to their needs. 14.2.2 rolling bearing type and characteristics, according to the shape of the rolling body, rolling bearings are divided into ball bearings and roller bearings. According to the main direction of load bearing can bear, can be divided into radial bearings (mainly bear radial load, thrust bearing) (axial load), thrust bearing (can bear radial load and axial load).

Q:What are the technical requirements and precautions for the assembly of plain bearings?: The basic function of plain bearings is to accurately locate the shaft and to support the shaft without damaging it under load. Shafts usually cost higher and are often uneconomical to replace. Selecting the bearing alloy that meets certain performance requirements can guarantee the minimum wear of the shaft.

Q:For sliding bearing, bearings, bushings, bushing and difference function: There must be a sliding bearing bush, but would not necessarily be a bush. Can also consult the Internet under the Luoyang union large bearings

Q:In power plants, are the bearings used in turbines rolling or plain bearings?: Because of the high speed of the turbine, it is usually a sliding bearing. Rolling bearings are used only for low speed generators.

Q:Why are the bearings on the crankshaft of the engine sliding bearings? So high speed, sliding bearings friction is not great?? Fever will not be great? Please prawns in detail, thank you: The reasons are as follows:The main reason is that the sliding bearing sleeve is two pieces, so it can be installed on the crankshaft. The rolling bearing can not be installed on the crankshaft.The utility model has the advantages of simple structure, low cost, easy lubrication, convenient installation, easy sealing, low noise and high precision. As long as the material pass, wear little.In addition, for a precision problem, nor is it suitable for other bearings.As for other places, both work speed, noise, work conditions, rotation accuracy, withstand shock, vibration ability, maintenance is not the same. The sliding bearing has the characteristics of high bearing capacity, good seismic resistance, low noise, long service life, etc. the rolling bearing has the characteristics of shock, vibration, noise and sealing. Rolling bearings are standard parts, easy to change. Plain bearings consume nonferrous metals.

Q:What are the properties of plain bearing alloys?: The sliding bearing alloy should have the ideal organization of both hard and soft:(1) soft matrix and uniformly distributed hard point.(2) a soft particle is arranged on the ideal tissue of the hard base sliding bearing alloy. 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.(3) the sliding bearing alloy has sufficient compressive strength and anti fatigue performance; good performance for reducing friction (friction coefficient is smaller); reserve good lubricating function; good adaptability; good thermal conductivity and corrosion resistance; good process performance, which is easy to manufacture, low price.

Q:What conditioning calculations should be performed for non liquid friction sliding bearings?: Therefore, the current methods of calculation are indirect and conditional. Practice has proved that if the limit pressure of P is less than or equal to P and the pressure and velocity of bearing product of PV is less than or equal to PV, then the bearing is able to work very well.

Q:Advantages and disadvantages of plain bearings relative to rolling bearings: I don't know much about sliding bearings, but according to my understanding of a little volume is divided into several aspects: sliding bearing roller bearing, can be very thin, thinner than the needle bearing speed, noise, life and other properties: sliding bearing ratio of rolling bearing, sliding friction to rolling friction than for small, energy relatively small losses. Therefore, whether in noise or at the highest speed, the rolling bearing is superior, and the friction is relatively small, and the life is relatively long.

Q:What are the main structures of radial plain bearings? What are their respective features?: Self - aligning bearings can automatically adjust the axis to accommodate the deflection of the shaft
