Speed reduction motor rolling bearing clearance is too large or too small hazard

Working clearance is an important quality standard for rolling bearings of geared motors, and is also an important parameter in the use of rolling bearings. Rolling bearing working clearance is not suitable will cause serious harm to the geared motor, the following to introduce the geared motor bearing working clearance too big and too small harm

1. the working clearance of rolling bearing of gear motor is too small

When the working clearance of the rolling bearing is too small, the friction torque increases, generating a lot of heat, easily leading to rolling bearing heat damage. This is due to when the working clearance of rolling bearing is too small, it will lead to poor lubrication of rolling bearing rolling body and rolling bearing inner and outer ring. Dry friction will generate a lot of heat, which will lead to wear, gumming, expansion and cracking of the inner and outer rings of the rolling bearing, all of which will cause damage to the rolling bearing.

2. gear motor rolling bearing clearance is too large

The working clearance of rolling bearing is too large, mainly caused by the natural clearance of rolling bearing is chosen too large, the pressure of rolling bearing is not enough. When the gear motor is running at high speed, the natural clearance of the rolling bearing is larger, causing the working clearance is also relatively large, which will cause the gear motor to vibrate more during operation and reduce the service life of the rolling bearing.
