Raceway as Timken bearings rotation rolling body Raceway when scrolling and inspire in a smooth and continuous noise only when the sound pressure level or tone only when great attention. Raceway sound when excited by sound energy is limited, as in the normal case, quality 6,203 raceways for 25~27dB. This noise to radial load of single row deep groove ball bearings are the most typical, it has the following characteristics:
1, axle bearing maintenance: in good condition for as long as possible in order to maintain original performance of the bearing, maintenance, overhaul, in order to prevent accidents, it is imperative for to ensure operational reliability, increase production, economy.
Maintains the best machinery operating conditions operating standards, carried out on a regular basis. Contents include monitoring the operating status, to supplement or replace lubricants, periodic removal of checks. Operation maintenance matters, INA bearings in rotating tones, vibration, temperature, lubricant, and so on.
2, bearing maintenance: cleaning of bearing: when removing bearings under overhaul, first recorded appearance of the bearing, confirm that the residual amount of lubricant, after checking the lubricant used for sampling, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Removed bearing wash, heavy wash and light cleaning, placed in a container, placed on the bottom of the metal mesh, bearings do not directly contact the dirt container. Coarse cleaning, if you rotate the bearing with dirt, can damage the bearings of rolling surface, should be noted. In crude oil cleaning, use the brush to clear grease, adhesive compounds, after largely clean, sperm washing.
Sperm washing, is in cleaning oil side the bearing rotation and careful cleaning. In addition, the cleansing oil to keep clean.
3, bearing maintenance and judgment: in order to determine whether removing NSK bearings can be used to check after the bearings clean. Check the Raceway surface, scroll bars, status of the mating surfaces, wear of the cage, the increase in bearing clearance and has nothing to do with dimensional accuracy to decrease injury exceptions. Non-separation of small ball bearings, the inner level of support with one hand, rotate the outer ring to confirm fluency.
