How to do a good job of lubrication of the motor?

How to do a good job of lubricating the motor. When running like other motors, the following lubrication is needed, which can not only speed up the operation of the motor, but also protect the normal operation of the motor. How to do a good job of lubrication of the motor? Specific to see the following elaborate circumstances.

When choosing grease according to the motor bearing load, the grease with small penetration should be selected for heavy load. In high pressure work in addition to the needle into the degree of small, but also a higher oil film strength and extreme pressure function. When choosing grease according to the environmental premise, calcium-based grease is not easily soluble in water and is suitable for dry and less moisture environment. When choosing grease according to the working temperature, the main index should be the drop point, oxidation stability and low temperature function. The drop point can generally be used to evaluate the high temperature function. The actual working temperature of bearings should be lower than the drop point of 10-20℃. The service temperature of synthetic grease should be lower than the drop point 20-30℃.

Motor lubrication, is also a cause of poor lubrication, the splash type of lubrication, mainly used in high speed occasions, for this medium load, low speed is obviously not appropriate. Enclosed life gear box with long life and less maintenance, boiler feed gear box, gear chain variable transmission, planetary reducer lubrication, can also be used for centralized grease supply equipment lubrication.

The unreasonable lubrication mode of the motor and the defects in the structural design lead to the unreliability of the motor in application. Reflected problems, first of all, the service life is reduced, followed by sound and vibration, resulting in frequent maintenance. And each time the maintenance, must replace the eccentric bearings and needle gear sleeve, so that the maintenance costs increase. Bearing's work is not very stable, due to the effect of gravity and the vibration of the mechanical movement of the inevitable cause bearing in axial position of trace amounts of displacement, the relative motion is very harmful, unceasing impact is likely to lead to the elastic deformation of the retaining ring and broken, the risk of bearing has become detached from the shaft, even bearing don't fall off, also can cause a lot of noise because of the vibration.
