In the large electromechanical bearing application process, cleaning and maintenance to ensure the electromechanical proper functioning of the key. How to clean and check the bearing, so small you sum up the three steps.

1, bearing the cleaning and inspection

Large motor bearings are individually boxed shipped out of the box after the first screw rings on the tile under the tile were removed well marked with kerosene cleaning with a dry cloth and check all gutters are clean, with or without casting residue sand the tungsten layer watt binding bad to draw the channel, the crack presence of trachoma and other dopants). If you can not fix, you will have to re-hang the tungsten gold.ball bearing companies

2, cleaning and checking of the bearing

The bearing seat installed cited should be carried out to thoroughly cleanse the examination. Bearing housing cavity with a scraper dirt scrape off, wipe them off with a cloth dipped in gasoline or solvents, watch cracks and trachoma, in order to prevent oil leakage in the operation. Bearing cap and bearing joint s, bearing seat and bearing the oil deflector binding surface scrape with feeler, shall not be greater than 0.03 mm gap. The place chock floor surface should clean up, there should be no bumps, rust and burrs. Fastening screw bearing and seat board thread to his fine check and try to tighten the screws the check too tight or bald buckle.ball thrust bearing

3, bearing insulation structure

Between the bearing and the bottom plate to cushion the insulating pad or metal gasket, the metal gasket is used to adjust the seat horizontal position. To adjust the motor and coupled to another motor or mechanical relative position. The metal gasket is made of from 0.08 to 3 mm of sheet metal. The insulating pad is made of a cloth laminate or glass filaments laminate. Place the insulation pad main purpose is to prevent harm to the current axis. The insulating pad should be higher than the bearing h ousing on each side width of 5 to 10 mm and a thickness of 3 to 10 mm. In addition to the insulation pad is placed between the bearing and the bottom plate, while the screw and stable nail should also be insulated. Insulating gasket with a thickness of 2 to 5 mm glass cloth plate, its outer diameter is larger than the outer diameter of the iron washer 4 to 5 mm. In contact with the bearing seat Tubing disk insulating pad available a thickness of 1 to 2 mm made of a rubber plate. After the installation of the insulation of the bearing should check the insulation resistance to ground, with 500 volt megger measuring its resistance should be not less than 1 megohm.ball screw bearing
