Q: What are the commonly used journal bearings?: Split bearing more than two parts. In order to improve the friction properties of the bearing surface, it is often to cast a layer or two layers of antifriction material on its inner surface, called the bearing lining, that is, the Bush is made of double metal structure or three metal structure. The bearing and the bearing seat do not allow relative movement. In order to prevent the movement of the Bush, the flanges at both ends of the bush can be used for axial positioning or fixed on the bearing seat by means of pins (or screws).

Q: while the automobile wheel shafts and reducer gears use rolling bearings?: The main sliding bearing sleeve is two pieces, can be installed on the crankshaft, the roller bearings 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: Sliding bearings can be used for structural requirements on opposite occasions: (two) the types and characteristics of rolling bearings; 1. classification of rolling bearings according 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 friction resistance, quick starting, high efficiency, simple lubrication and easy replacement. (2) disadvantages: poor shock resistance, noise at high speed and long service life, as opposed to 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.

Q: What are the assembly points of plain bearings?: Sliding bearing installation should first remove encapsulation with protective rust agent (closed bearing installation, except) can use hydraulic method of bearing inner ring applied no impact loads will be fitted to the shaft bearing qualified bearing block, if there are no conditions can also use Pratia gently on the inner ring of the bearing installation in general, bearing allows color heating sleeve, but heating temperature not exceeding 100 degrees, and the bearing should be relatively uniform for heating.

Q: What are the tolerances and finishes for plain bearings and shaft mating surfaces?: Tolerances and surface roughness of mating surfaces of plain bearings and shafts:1. milling machines, drilling machines and lathes, gear reducer and worm gear reducer using sliding bearings, sliding bearing holes and shaft outside circleMatching H7/f7; surface roughness: sliding bearing bore Ra0.8, outer circle Ra0.8---Ra0.4.2. motors, centrifugal pumps, fans, steam engines, sliding bearings used in crankshaft and connecting rods of internal combustion engines, sliding bearings, bores, and shaftsMatching H9/f9; surface roughness: sliding bearing bore Ra0.8, outer circle Ra0.8---Ra0.4.3. agricultural machinery use of sliding bearings, sliding bearing holes and shaft outer circle, select H11/d11;Surface roughness: internal bore of sliding bearing Ra1.6, outer circle Ra3.2---Ra1.6.

Q: Failure forms of plain bearings, failure forms of plain bearings: 5. corrosion: oxidation of lubricant to acid substance corrosion.

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: 250 kilowatts of motors, replacement of new bearings, after driving bearing fever, the bearings inside the grease all thrown out What's the matter? Expert answer!: Bearing heating causes:(1) the temperature of motor bearings is high. It is suspected that the gap between the couplings of the equipment is not adjusted properly, and a little vibration causes the excessive temperature rise of the bearings.(2) the rationality of the motor design, manufacturing quality, installation quality, etc..(3) bearing quality problems caused by heating, bearing gap.Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient (friction, coefficient) during movement, and guarantee its rotary accuracy (accuracy).According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts, namely, outer ring, inner ring, roller and cage. Strictly speaking, the rolling bearings are composed of six big parts, namely, outer ring, inner ring, rolling body, cage, seal and lubricating oil. Mainly with the outer ring, inner ring, rolling body can be defined as rolling bearings. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.
