Eight internal factors of bearing failure
When the bearing structure design, manufacturing process and material quality problems, are likely to lead to the bearing failure state, in order to make use of the bearing is better performance, we must learn the following reasons about bearing failure, it includes the following eight kinds of internal factors.
1, bearing damage. Check whether the bearing of the ball bearing or the ball bearing of the ball bearing is damaged. In case of damage, repair or replacement.
2, lubricating oil impurities, dirty, oil ring stuck or brand no.. Oil should be changed to check the reason for the repair, the oil viscosity is too large, you should replace the lubricating oil.
3, bearing room oil shortage. Grease should be added, filled with 2/3 oil or oil to the standard oil level.
4 、 the grease in the rolling bearing is blocked too much, the temperature of the lubricant in the overall eccentric bearing is too low or too high. Excess grease in rolling bearings shall be removed or grease filled in the oil tank to 2/3.
5, bearing and shaft, bearing and end cover with too loose or too tight, it will make the whole eccentric bearing deformation, too prone to "run off". When the bearing and the shaft are too loose, they can be coated with metal paint on the axle neck. When it is too tight, it will be re processed; the bearing and the end cover are too loose, and the end cover will be tightly packed and re machined when it is too tight.
6, the motor cover or bearing cover is not assembled, usually not parallel, resulting in the overall eccentric bearings are not in the correct position. Tighten the bolts at both ends or bearing caps and tighten the bolts.
7, belt too tight, too loose or coupling assembly is not good. Adjust belt tightness; local coupling.
8, the maintenance of the wrong type of bearing. Replace the correct type of bearing as soon as possible. |
