Motor bearing buyers reaction shaft lubrication trouble very cumbersome, for any lubrication method of simple point? So small make up to bring us five today you don't know the motor bearing lubrication tips. Started from the most basic definition of motor bearing: motor bearing, everybody is often referred to as the motor bearings, is specially applied to a special bearing on the motor. Motor used in bearing is a supporting shaft parts, can guide the axis of rotation, also can withstand the above the shaft parts. Motor commonly used there are four types of bearing, the rolling bearing, sliding bearing, joint bearing and oil bearing. Many motor bearing lubrication method, including: oil bath, oil, oil pump and so on are all very good lubrication method. To explain in detail next small make up for all these techniques the five skills a motor bearing lubrication, oil bath lubrication, is ordinary in the motor bearing lubrication method, suitable for low, medium speed, bearing lubrication. Immersion in the slot, part of the bearing lubricating oil by the bearing parts of rotation, and then flow back to the oil level of oil tank should be slightly lower than the lowest at the center of the roller. Second, the drops of oil lubrication, suitable for the need to ration oil stainless steel bearing components, general every 3 drops of oil A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. Third, the lubrication oil pump, oil pump in the conversion of the filter oil transfer to the imported motor bearing parts, through the bearing lubricating oil filter cooling after use. Due to the circulating oil can take a certain quantity of heat, cooling the bearing, therefore method is suitable for high speed bearing parts. Four, oil mist lubrication, mixed with dry compressed air after the sprayer and oil formation oil mist, spray import motor bearing, can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed, high temperature lubrication bearing parts. Five, high pressure injection lubrication, high pressure oil in the oil pump shot into the bearing, the nozzle into the stainless steel bearing the bearing at the other end into the oil in the tank. When bearing at high speed, rolling element and cage with high rotate speed makes the surrounding air, the air in general it is difficult to be sent to the bearing lubricating oil lubrication method, then must use the method of high-pressure jet spray the lubricating oil to the bearings, the position of the nozzle must be between inner ring and maintains a center.
