Running in the INA motorized spindle bearings lubricated overhaul and maintenance of common sense

Removed INA bearings cleaning, and can be divided into rough washing and fine washing, first put down bearing respectively on the container, first put on the metal mesh at the bottom of the bearing is not direct contact with dirt from the container. Rough washing, if the bearing with dirt, can injure the rolling surface of the motorized spindle bearings, should be protected. Use cleaning brush to wash the oil in the coarse, remove grease, adhesive, after clean, roughly into fine cleaning process. 1, grease lubrication of INA bearings and lubrication is the best in the equipment downtime and implementation of the plan and added on a regular basis, at the same time, the old rid grease or via the drain the old oil out empty. Before adding fresh grease injection nozzle should be wiped clean. If there is no zerk bearing box, should open the bearing box cover or end cover, in order to remove the old grease, clean up after, supplement the same type of fresh oil. 2, lubricating oil, check the oil level of lubricating oil and the oil, in general, a normal oil level equipment oil level Windows or mark a third - Two-thirds of the range. Oil compensating way for oil cup, the display of the oil level represents oil compensating ability, and the bearing box oil level is to meet operation requirements, oil cup CPC a lower than a quarter of its total volume filling oil may be considered. Check and repair method oil, remove a small amount of oil as a sample and fresh oil, has the ability to unit may be considered for oil testing, to ensure the oil qualified. If the sample looks like clouds, so may be mixed with water as a result, people often say that oil emulsification, at this time should replace the lubricating oil. INA bearing inspection and judgment: in order to judge whether the electric main shaft bearing of the removed can continue to use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Separation of INA bearings and bearing, rolling body, the outer ring raceway surface can be respectively.
