Q:Maintenance method of plain bearing
Bearing repair, installation quality is not high, 1, improve installation quality, reduce bearing vibration2, to prevent partial load and overload3 、 adopt suitable Babbitt and new bearing structure4, strictly control the bearing temperature riseBecause the grease dirt nap of large particles into the bearing gap, and embedded in the bearing bushings, bearing and shaft neck (or thrust plate) contact, hard callus formation on the surface, it will seriously scratch the shaft, bearing oil picking attention clean, especially in maintenance, should pay attention to the metal chips or clean dirtWear and tear due to impurities in the lubricating oil, foreign matter and dirt.
Q:Why can not the surface roughness of plain bearing surface be too high?
Because the process of start and stop, because of low speed shaft neck and sliding bearing contact friction generated, if the axis roughness is too large, it will increase the friction, easy to wear and sliding shaft bearing, so the shaft neck surface roughness is not too high.
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:What are the parameters of maximum bearing capacity factor Cp of plain bearings?
Therefore, Cp is the function of the journal position in the bearing, depending on the angle of the package angle (i.e. the angle between the entrance of the oil inlet and the outlet) and the eccentricity ratio, the chi square and the aspect ratio B/d, as shown in table 1.
Q:Are plain bearings grease lubricated?
Whether it is oil grease, need to first select the appropriate viscosity or consistency, viscosity is too large internal friction resistance increases, dynamic wear is also increased, so the friction heat is also increased, and accelerating the oil deterioration, above a certain temperature, will accelerate the fatigue wear. Once the viscosity is too small, the lubricant film is thin and the strength is not enough, only friction and wear, and even produce non fluid lubrication or dry friction, thereby damaging the machine.
Q:Bearing is the bearing?
No, that's the combination of the bearings and the sockets.
Q:What are the advantages and disadvantages of rolling bearings?
3. The rolling bearing is compact in structure, small in size, light in weight and easy to install and disassemble. Each part of the rolling bearing realizes the standardization of size, which is not only beneficial to the production of the rolling bearing, but also to the interchange of the parts of the rolling bearing so as to make it easier to be repaired and maintained.4, most of the rolling bearings using bearing steel as the main material, plus standardization, serialization of parts design, more conducive to large-scale industrial manufacturing, quality stability guaranteed.
Q:What are the common sliding bearing bushing materials? What are the characteristics of each?
5) bearing alloy (Babbitt). It is tin, lead, copper, antimony and other alloys, with good wear resistance, but low strength, can not be made into separate bearings, usually cast in bronze, cast iron, steel and other bearing matrix.6) three layer load bearing material. Commonly used in two kinds: polypropylene, polypropylene, steel body composite materials and POM steel body composite.
Q:Sliding bearings can be used for structural requirements on opposite occasions
3. radial sliding bearing (1) integral and split division 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 bearing (understand) (1) 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.
Q:This problem has been bothering me for a long time.
Antirust function is used in the grease inside the bearing, need to have antirust effect, antirust agent best can not dissolve in water. Grease should have good adhesion. It can form an oil film in the name of steel. What kind of bearing is good, even if the grease is filled with water, it can also keep it. Mechanical stability. Grease will soften during machining and cause leakage. When an example of vibration is applied, the grease is thrown from the bearing housing into the bearing. If the mechanical stability of the grease is not enough, the grease will always be thrown out of the bearings, which will lead to mechanical disintegration of the soap structure and the use of grease. The oil seal is required to maintain bearings and lubricants to avoid external contamination, regardless of debris or moisture, which can not penetrate the bearings to prevent damage. Proper device maintenance is an important factor in using the longest life of the bearing.
