Analysis on vibration factors of aligning ball Bearing during operation
Bearing is the main vibration source of the vibrating screen is difficult to control, because the vibrating screen is a great excitation force to maintain the limit speed and friction coefficient of the working bearing, so the radial force of the bearing is very large, the vibrating screen in the process of working, the great excitation force will cause the elastic vibration of the bearing system.If the lubrication is poor, there will be greater friction so that the bearing temperature rise is too high, the thermal expansion is too large, so that the radial clearance is significantly reduced, so that the friction is intensified, and the temperature rise is further improved.
