Install bearings with hot charging method can not give bearings to increase the pressure to complete the job in a short period of time.
Bearing hot charging to pay attention to:
1, the bearing temperature must not bearing heated to over 120 degrees
2, so that the bearing does not directly contact with the sump bottom To bearings on the stage of the metal mesh
3, the bearing was heated to 20 degrees -30 degrees higher than the desired temperature, so that the operation will not occur inner ring cools, it is difficult to install
4, the installation of the bearing cools down the width direction of the contraction, so that tightening of the nut or other suitable method, so use the shaft to prevent the gap generated between the inner ring and the bearing shoulder block.
In this case generally depends on the bearing is caused due to a foreign body, indentation, scars, dysfunctional, install adverse mount processing adverse uneven rotation torque, the clearance is too small, installation errors, seal friction caused by the torque is too large and so on.
Large machinery can not manually rotate in this case, so no-load power is turned off immediately after the start coasting. Check for vibration, sound, rotating parts contact. After confirming that no abnormal into the power running.
