Raceway on bearing raceways and its control method is when the bearing operation, rolling it in rolls issued a slippery road surface rolling on a continuous sound, are all typical of cylindrical roller bearings occur. General bearing Raceway acoustic sound that is combined with other sounds.
Control method of the Raceway: Optional low noise bearings bearing corrugated-small, carefully selected using criteria. Rolling road sound often affects the entire mechanical noise, reducing Raceway can reduce the noise of machinery as a whole.
1, cylindrical and oval-shaped Bush backlash, scrape or use hand research bearing pad in turn adjust the post shave method.
2, cylindrical and oval top clearance of the bearing, manual scraping or when circumstances allowed the Institute to pad method of adjusting bearing surface.
3, to much oil wedge fixed bearing, scrape and adjust the clearance between Bush sleeves are not allowed in principle, gaps are not new tiles should be replaced in due time.
4, tilting oil wedge Bush, does not allow tile scraper, gap is not due to pad should be replaced in due course. Adjustable thickness of the tile, blocks can be adjusted through behind the tile and stainless steel under mat, or decrease thin thickness of block method to adjust the amount of Watts. Note to much oil wedge tilting bushing, tile thickness tolerance among the same group should be less than 0.01mm
Impact sound and its control method of rolling ball bearings or cylindrical roller bearings of the larger models in under purely radial load at low speed operation, due to less centrifugal force of rolling, rolling shock is in the area of non-load roll cage or road noise. But as the speed increases, this noise will disappear. Rolling control method for impact sound: appropriate reduction of radial clearance, reasonable structure and material compliance of cage bearings.
