Bearing high temperature should use gasoline or kerosene to clean before installing clean, dried, and ensure good lubrication, TIMKEN high temperature bearing grease lubrication, or oil-lubricated. Grease lubrication, the selection should be free of impurities and anti-oxidation, Rust prevention, extreme pressure grease for superior performance. Grease fill for heat-resistant bearings and TIMKEN high temperature bearings 30% per cent of the tank capacity, should not be too much. TIMKEN with sealing structure of high temperature resistant lubricating grease for bearings have filled up, the user can directly use, can no longer be cleaned.
TIMKEN bearing high temperature installation, you must exert equal pressure on the circumference of the ferrule end face, press the ring into, 构词成分。 the first percussion tools direct high temperature bearings must not be used face, so as not to damage heat-resistant bearings. In the case of less interference, at room temperature, using the sleeve pressure TIMKEN high temperature bearing ring face, using hammer tapping sleeves, sleeve rings through balanced press. If installed in large quantities, to be used in hydraulic machines. When pressed, should ensure that the outer ring side face and shell shoulder end surface, end face of the inner ring and shaft shoulder end surface clamping, gaps are not allowed.
When the interference is large, to be used in induction heating for oil-bath heating or TIMKEN bearing high temperature method to install, heating temperature range of 80 ° c-100 ° c, the maximum must not exceed 120 ° c. At the same time, nut or other suitable method of fastening TIMKEN high temperature bearings, bearing cooling after the high temperature resistance in order to prevent shrinkage and width clearance between the ring and shaft shoulder.
TIMKEN bearing high temperature rotating test shall be performed after installation, first used for the axis or high temperature bearing boxes, without exception, will-power without load and low velocity operation, functioning and then gradually increase the rotation speed and load, and detect noise, vibration and temperature, abnormal findings should be stopped and checked. Running test after normal delivery.
TIMKEN bearing high temperature installation final clearance adjustment should be carried out. Clearance values shall be based on use condition and the coordination of the different size and specify the amount of interference. If necessary, the test should be carried out. Double row tapered roller bearings and pump bearings have adjust the clearance at the factory, installation without adjustment.
