Cause of overheating of high temperature bearing

1 lubrication reasons: bearing grease injection too much, more than the bearing cavity space of 2/3, due to the grease heat transfer efficiency is not high, resulting in poor bearing heat. Can clean the oil when bearing grease fill, bearing cavity injection, the 1 / 3; if the daily operation of fill oil, bearing cavity injection, the 1 / 3-2 / 3 is appropriate.

2 mechanical vibration causes: poor coupling vibration, bearing seat stiffness caused by lack of vibration and bolt loosening caused by vibration. Vibration causes the bearing to receive a non - normal extra load, resulting in excessive pressure to cause the bearing to heat. Coupling must be strictly to find the right, strengthen the bearing base, improve its stiffness; according to the provisions of torque fastening bolt.

3 reasons: the outer ring of the bearing assembly pressure too tight deform caused by friction torque is too large. Solution: the bearing outer ring generally should not be pressed too tight, this is because the rolling body rolling torque is less than the outer ring of the bearing sliding moment.

4 environmental factors: the system is not enough sleep or interrupted sleep, indoor space is narrow and small ventilation, hot summer heat. Ensure that the cooling water flow, increase the heat dissipation capability of ventilation, the summer before the advent of oil bearing cleaning and maintenance timely.

5 operating reasons: the most one-sided pursuit of production, increase in accordance with the. Zhou Chengchao load operation. Should be reduced to normal rated load.

6. Bearing inner and outer ring cracks, cage excessive wear clearance exceeds the ultimate limit of wear, body rolling Tasikmalaya appeared serious defects. The bearing scrap, update the new bearing.
