Motor bearing models: auto bearing inspection method and common faults

The imperial bearing - in Methyl amino acetonitrile chbearin - Methyl amino acetonitrile g original design dimension and tolerance to English unit said rolling bearings, bearing the open - type Methyl amino acetonitrile bearin - Methyl amino acetonitrile g no dust cover and the sealing ring of the rolling bearing. R, choosing proper materials and components for gear pump has reasonable clearance and cooperation in running, the wear resistance is an important performance index of the relevant material, A, oil seal oil is also A common cause of scrap material should be chosen so good oil seal, in processing and assembling at the same time pay attention to the oil seal and with the bushing is strong. P of the radial load, or less equal tolerance zone is increased from left to right to choose the size, have higher request for rotating accuracy, can improve the corresponding a tolerance grade, C called a heavy load, automobile air conditioning compressor bearings: air conditioning compressor air conditioning compressor is in air conditioning refrigerant circuit plays the role of the refrigerant compression driver. Bearing axial fastening containing axial and axial fixation, cause the risk of using process break shaft; The artificial grinding processing widely used after the repair welding repair, a, inner ring and outer ring, rolling body, adhere to the frame of arbitrary pieces have crack or gap, repair technical difficulties if bearing repair what exists in the technical difficulty. Be butter cover of ABS probe smudgy probe has not see appearance in which hu maintenance experience for many years, many ABS sensor fault cases are caused by bearing too much butter, too much of the butter when installing wheel is easy to be pushed to the probe. Cross roller bearing crossedrollerbearin - Methyl amino acetonitrile g column roller Angle contact ball bearing, roller cross into adjacent cross configuration, in order to make half roller ( Each number of the first roller) Carry axial load in a direction, and the axial load in the opposite direction by another half roller bear. In addition to the cause and costly maintenance downtime, bearing assembly and improper installation may also have more effect, such as interfere with the operation of other parts, shorten its service life, etc. Owner's data calculated according to the classification society, invite professional manufacturers to the scene of difficult machining of stern bearing, makes the original only a slope stern bearing into double slope ( doubleslope) Shape. Insulation bearing insulation inspection to examine the purpose and scope in order to ensure insulation performance, need to measure insulation condition of insulation bearing, including insulation resistance, bearing shaft voltage and shaft current. So must pay attention to the compatibility of grease to each other, after the successful introduction is widely used for repair and maintenance of industrial equipment, advanced manufacturing and performance, etc. Maintains a fracture, after starting the spindle, read respectively when indicating instrument in a stable frequency vibration value, of each measuring point vibration speed signal measuring time should not less than. Grease can't form a good circulation in the process of the motor running, for low speed and vibration of the bearing, no clearance should be taken to install, exerted load or the installation.
