SKF Bearings noise is a deep groove ball bearing itself, that is, bearing the inherent noise; the other is the noise generated by the bearing capacity before, and bearing their own noise. We introduce how to scroll through the SKF Bearing sound check and deal with the problem.
a) the inherent noise: raceway sound with a variety of deep groove ball bearings and rolling friction sound SKF bearings inherent sound, the raceways sound generated by the elastic properties of the rolling element and raceway contact, deep groove ball bearing swivel , the rolling body raceway rolling issued in a continuous and smooth sound; normal rolling friction sound may issue a "creak, creak like an uncomfortable metal friction unusual sound, not to issue such a well-oiled sound is not a problem under normal circumstances, only after the increase of the noise must be noted.
b) with SKF bearings manufacturing-related noise: including keeping the aircraft noise and vibrato, cage noise occurs mainly in the ball bearings and deep groove ball bearings, impact due to cage vibrations and keep the frame and rolling element bearing swivel will sound the sound has a periodic vibrato (all kinds of bearings) is a certain frequency of sound, is due to the raceway surface of the larger waviness caused by vibration generated by this phenomenon is the most common problems in future we need a lot of attention to before.
c) use of improper noise: there are a variety of SKF bearing raceway surface or rolling surface by the bumps, the pressure pit, corrosion, it will produce a certain period of noise and vibration when the deep groove ball bearings dust intrusion dirt, noise is generated when in operation. This noise is non-cyclical, also accompanied by vibration, the sound is not fixed in size, from time to time.
For some industries, the deep groove ball bearings, played a crucial role. When SKF bearings under the following conditions, please do not continue to use the new bearings should be replaced immediately.
Deep groove ball bearings are precision parts of machinery and equipment, deep groove ball bearings for mechanical services, preventive maintenance means, condition monitoring and maintenance decision support system to optimize plant asset efficiency and maintenance work. Avoid not necessary to the accident:
(1) SKF bearing inner ring inner diameter of the surface or the outer ring outer diameter surface, the apparent creep; (2) the bearing inner ring, outer ring, rolling body cage any cracks or gaps; (3) bearing raceway ribs, rolling on the card hurt; (4) The apparent discoloration caused by heat; (5) on the raceway, rolling element bearing, rust, and injuries; (6) serious indentation and hit marks on the bearing raceway, rolling element; (7) bearing cage wear significantly, or rivets significant relaxation;
