Maintenance of the deck crane bearing

Remove deck crane bearing overhaul, the first records bearing appearance, confirm the remaining amount of lubricant, after sampling inspection by the lubricant, cleaning bearings. As a cleaning agent, general use gasoline, kerosene.
Removed bearing cleaning, cleaning rough and fine washing, respectively in the container, metal mesh on the bottom first, make the bearing does not directly contact the container dirt. Rough cleaning, if you rotate the bearings with dirt, can damage the bearing rolling surface, should pay attention to. In the crude oil washing, use the brush to remove grease, adhesive material, generally after a clean, to wash.
Sperm washing, cleaning of oil bearing is in while rotating, while carefully cleaned. In addition, cleaning oil should be kept clean.
Dismantled in order to determine the bearing can then use, should check the slewing ring bearings cleaned, carefully check the raceway surface, rolling surface, with the surface state, maintain and increase shelf wear, bearing clearance and non dimensional accuracy on the decline in injury, abnormal. Non separation of small ball bearings, inner ring with one hand supporting level, to confirm whether the smooth rotating ring.
Bearing separation type bearings, can check on the raceway surface rolling body, the outer ring, because large bearing cannot rotate with the hand, pay attention to check the rolling, raceway, cage, retaining boundary surface appearance, Crossed Roller Slewing Bearing shall carefully check the higher importance.
Large machinery can not be manually rotated, so the no-load starting immediately after power cut, mechanical idling, check whether the vibration, noise, rotating parts are in contact and so on, confirmed no abnormal, into the dynamic operation.
Power operation, from the no-load speed, slowly increased to the rated operating condition. Test run of issues, whether there is abnormal sound, bearing temperature, lubricant leakage or discoloration etc.. If abnormal, should immediately suspend the operation, inspection machine, necessary to remove the bearing inspection.
