Fixed FAG angular contact ball bearings run six major matters need attention

Using thermal device can monitor the bearing temperature at any time, and realize e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said bearing is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes FAG bearing overheating can be classified in angular contact ball bearing of the lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuity of bearing temperature monitoring is necessary, angular contact ball needle bearing whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. Bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if using the oil hole can directly measure temperature of bearing outer ring, angular contact ball bearing is more appropriate. Usually, the temperature of the bearing with FAG bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. 1. Shoulder fixed angular contact ball bearing inner ring axial fixation rely on the shoulder and interference. Applicable to both ends fixed supporting structure. Simple structure, small outer profile size. 2. Elastic ring fixed imported bearing inner ring by the shoulder and lock nut axial fixation. Affordable small two-way axial load. Axial structure size is small. 3. Lock nut fixed angular contact ball bearing inner ring by the shoulder and lock nut axial fixation. And a lock washer with locking, safe and reliable, suitable for high speed and overloaded. 4. End thrust washer fixed Angle contact ball bearing inner ring by the shoulder and shaft end ring axial fixation. Shaft end ring on the shaft end with screws. Set screw should be locking device. Should not be applicable to the shaft end cutting thread or space limit. 5. Sleeve is fixed on fixed set of inner hole of the radial dimension is compressed and clamped on the shaft, to realize the angular contact ball bearing inner ring axial fixation. 6. Backing down the clamping sleeve sleeve fixed way is the same as the set set. But withdrawal sets with special nut, angular contact ball import axial loading and unloading of convenient, suitable for radial load is bigger, smaller FAG bearing axial load on the optical axis fixed. Angular contact ball bearing seat improving design of main bearing is within the frame of the normal position, prevent after the bearing seat and frame wear axial additional load, but also to make and support as far as possible in a parallel state, can effectively eliminate the additional eccentric torque. Thrust bearing lugs on both sides of the add a skateboard, it's main purpose in order to adjust axial clearance, reduce wear compensation thrust lugs on the side. Using the flexible nylon cage, prevent dirt intrusion FAG bearing raceway, maintains a twist off and sticking steel ball. And as the point of application of the force of bending roll and settle hardened wear resistant block, its purpose is to in the produce of roll bending axial additional load. Increasing the angular contact ball bearing internal clearance, changed from the original general grade to the third and fourth auxiliary clearance.
