Thread Content
What is the reason for the bearing damage? The motor is variable frequency. I beat butter once every three months and it still looks like this. Some people say that it is caused by the generation of axial current. Please help me analyze it
Send photos of the bearings. So that everyone can help you with ideas.
Nowadays, the quality of motors and bearings used is very good. It is better to find the cause from installation and maintenance. For example, the axial force of the driven equipment affects the level, centering, and opening of the coupling. Whether the installation refers to the required parameters of the equipment. Some equipment reaches a certain temperature during normal use. When adjusting the coupling, the static and dynamic conditions must be adjusted in accordance with the instructions. In terms of maintenance, the main thing is the quality of the oil, which is very critical. It also involves the management of oil products. There is also the question of whether the requirements for reasonable oil injection are reasonable. For the above possibilities, it is best to refer to the equipment usage, installation, and maintenance instructions.
