Single row tapered roller bearings installed last clearance adjustment


When a large amount of interference , can be heated oil bath or induction heating device bearing method to install the heating temperature range is 80 ℃ -100 ℃, the maximum can not exceed 120 ℃. Meanwhile , the application of a nut or other appropriate methods tighten the bearing to prevent the bearing cooling after leaving the ring widthwise shrinkage gap between the shaft shoulder .

Single row tapered roller taper roller bearing installed last clearance adjustment should be carried out . Clearance values ??should be based on the use of different conditions and the amount of interference with the size of specifically identified. Necessary, should be tested to determine . Double row tapered roller bearings and water pump bearing has been adjusted at the factory clearance, installation without further adjustment .

Bearing rotation test should be carried out after installation , first hand rotating shaft or bearing housing , without exception, then in power for no-load , low speed , then gradually increase as the functioning of the rotation speed and load , and to detect noise , vibration and temperature , abnormal, should stop and check . Normal operation test before delivery.
