The agricultural motor small motor, in small electric motors, generally, is the ball bearings. Bearing fever is one of the most common agricultural the asynchronous motor fault. Bearing heat, light is the diluted grease leakage, while the bearing is damaged, causing economic losses to the user. On the causes and treatment methods of bearing heating is introduced as follows:
1, bearing damage. Bearing ball or ball bearing inspection of ball bearing is damaged. If damage should be repaired or replaced.
2, the lubricating oil with impurities, dirty, oil ring stuck or the wrong grade. Find out the reason should be oil, stuck to repair, oil viscosity is too large to be exchange lubricating oil.
3, the lack of oil bearing chamber. Should add grease with 2/3 oil or lubricating oil to standard oil line.
4, the rolling bearing grease blocking too much, too low temperature lubrication sliding bearing or excessive. Should remove excess grease of rolling bearings, the grease or oil chamber filled with to 2/3.
5, bearing and shaft, bearing and end cover too loose or too tight, too loose will cause the bearing deformation, prone to "run set". Bearing and shaft with too loose when the shaft neck coated metallic paint, processing re too tight; bearing and an end cover with the song the end cap tightly mounted, processing re too tight.
6, both ends of the motor cover or not assembled bearing cover, usually are not parallel, cause bearing is not in the correct position. Both ends of the cover or bearing cover stopping leveling, tighten the bolt.
7, belt is too tight, too loose or bad coupling assembly. Adjust the belt tightness; correct coupling.
8, maintenance for the wrong type of bearing. Bearing to replace the right type as soon as possible..
