Performance Evaluation on the High Temperature Grease for Motor Bearings
The grease used for motor bearings under high temperature conditions should not only have good high temperature lubricating properties but also possess excellent comprehensive performance to ensure the normal operation of the bearings in a wide temperature range.The paper con-structs a performance evaluation method for the high tem-perature grease used in motors,capable for verifying the ap-plication effect of the grease from multiple angles,further-more,the high-temperature and application performance of the grease are verified based on the working conditions of a certain permanent magnet motor.The verification shows that the selected grease has good high temperature perfor-mance but is not suitable for normal temperature conditions.The selection of high temperature grease should fully take the operating conditions of the bearings into account.
