The influence of the inner ring fixed on FAG bearing temperature

Bearing temperature increases, the first to see if there is an error action, if the temperature is indeed rising, should immediately do the following treatment: ( 1) Check the cooling water pressure, water flow and pipeline system is normal FAG bearings. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 3) Check for different bearing, bearing and testing degrees whether there are abnormal. ( 4) Take sample to observe whether the oil color have change, FAG bearings and chemical test to see if metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. Bearing if has shut, should fill oil, if it is sealed rubber gasket of oil leakage, should stop processing. Must try to avoid the occurrence of the phenomenon of U. S. bearing high temperature, so as to increase its service life. As is known to all, all FAG bearing in the process of active, inner ring must be fixed is good. The following bearing monopoly ( In aino fu bearing co. , LTD. ) A brief introduction of bearing inner ring fixed form. 1. Shoulder fixed 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 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 FAG 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 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 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, bearing loading and unloading of convenient, suitable for radial load is bigger, smaller double row spherical bearing axial load on the optical axis fixed. In a fixed FAG bearings, according to the above methods, will prolong the service life of bearing.
