Several abnormal conditions that cause overheating of planetary gear reducer bearings
Time：2020-05-24
The abnormal phenomenon that the high temperature of the planetary gear reducer bearing causes the body heating is a common and harmful mechanical fault of the reducer equipment. If handled improperly, the analysis is not clear, it will often cause the increase of the maintenance cost and shorten the service life of the bearing. Therefore, the rapid determination of the cause of failure, take appropriate measures to solve, is the continuous smooth operation of equipment.
Usually cause the planetary gear reducer bearing overheating one of the factors is: the adverse factors caused by lubricating oil. For example: lack of lubricating oil (grease), not on time to add lubricating oil, lubricating oil (grease) quality is not good, contains impurities, etc. (precision planetary reducer for life maintenance free, life without grease type).
Secondly, the use of environmental factors: some planetary gear reducer working environment dust, when some fine dust into the high-speed bearing seat, will cause the bearing seat lubricating oil or grease deterioration, poor lubrication, and then make the bearing wear. The bearing continues to run in the state of wear and tear. As the friction increases, the heat increases, which leads to the temperature rise of the bearing (the protection class of the precision planetary reducer is IP65, and the sealing performance is good, which can be used in _ environment).
Re_ is another important reason for bearing heating due to improper installation orientation. Because the correct installation of the bearing has a direct impact on its life and the accuracy of the planetary gear reducer, the center line of the shaft and the bearing hole must be coincidence when the installation is required. If the bearing position is not installed correctly, the accuracy is low, the bearing has a deflection, and the torque will be generated when rotating, causing the bearing to heat or wear. In addition, the bearing will also produce vibration, the increase of noise, will also make the temperature rise.
