Shaft voltage and shaft current erosion damage of bearing

The harm of bearing shaft voltage and shaft current erosion - 2018 11 - 29 in industrial applications, from simple exhaust ventilation equipment to complicated large power machinery and even high-speed engine unit, etc. , are the three phase induction or traction motor. These electric equipment, electric erosion problems often. Electric erosion is a bearing damage caused by the electric current flows through the bearing form, the production of shaft current caused the formation of shaft voltage. Current flows through the bearing, due to the discharge process, both inside and outside the bearing raceway and rolling body surface to form a large number of small holes, only a few microns in diameter friction surface loses luster even melting. Bearing in this case, will soon be failure due to wear and tear, appear this kind of circumstance, in addition to need maintenance, but also undertake the production loss caused by equipment downtime. In the planning stage beforehand to use insulation bearing is the best choice, it reduces the equipment service life and maintenance cost growth and avoid the shutdown losses caused by maintenance. Beijing snow Lin technology co. , LTD is located in the changping district in Beijing, specializing in manufacturing by using high performance coating means of key industrial parts with excellent performance, including insulation bearing is one of the important core products company. Company for the bearing surface of the insulation has a good solution. USES the most advanced plasma spraying technology, within the cylindrical bearing outer ring or circle round the insulation coating quality is prepared, and after coating, the company for the development of the insulation coating special deep hole sealing technology, especially the insulation performance boost!
