1, do not allow oil seepage, because plant grease or oil is likely to spill onto the coil, and harm the conductivity and damage the insulation layer.

2, be sure to pay attention to the running condition of the bearing, the bearing should be running evenly. If you find abnormal sound, shut down immediately.

3, should be taken off the grease or oil sample test on time, such as dark color, with moisture or residue, resulting in bearing dirt or fever need to be removed lubricating grease or oil. When removing lubricating grease or oil, the bearing or piston pin and motor shaft should be cleaned and wiped with automotive gasoline.

4. The time for removing lubricating grease from rolling bearings is carried out according to the requirements of the oil identification plate nailed on the motor shaft. The lubricating grease can be removed without shutdown, and the lubricating oil is added from the oil label with the lubricating oil pressure injector.

5, the inner and outer rings of the rolling bearing in all normal conditions should be tightened and not allowed to loose, such as finding that the outer bearing in the bearing room rotation or bearing hole rotation on the drive shaft, should be timely maintenance. The outer rotation is because the anchor bolt of the tightening bearing cover is loose, the inner hole rotation is because the stop screw on the puzzle ring or the oil baffle plate is loose, or because the clamping cylinder pin is loose, if there is more serious damage, it is necessary to replace the bearing and the drive shaft or the bearing and the bearing end cover and the roller bearing.

6, check the sealing ring and sealing gasket is not damaged, burned, embrittle, mildew and other conditions, if you have, be sure to replace, to ensure that all bearing device sealing good, felt sealing gasket surface should be coated with lubricating grease or oil, to prevent damage and burn.

7, in advance to prepare the application of long-term unnecessary motor, it is necessary to clean the rolling bearing car with gasoline, and then introduce the bearing chamber 0.5~0.7 chamber lubrication grease. If the lubricating oil is too much, it will not only cause oil seepage, but also cause the bearing to overtemperature when working, resulting in the dissolution of the lubricating oil. After the bearing is lubricated, the motor rotor of the motor should be very easy to rotate.
