What is the sound of the motor bearing?

How the noise of motor bearing is all normal motor bearing noise has always been a puzzled problem in many technical engineers. Motor bearing noise because can't use language describe, in so many cases distinguish above also have professional and technical personnel to the motor. The load section of the rolling element and cage collision 01 bearing roller run on bearing raceway, when the roller in the load section under the condition of operation, scroll feelings appear and cage in axial or radial collision. This is due to the rolling body itself out from the load area, has a certain angular velocity, also have a certain centripetal force, roller should closely revolve around the pivot, and maintains a collision occurs, resulting in noise. Especially in the area in the load, when the remaining clearance entity, that impact noise especially significant. Rolling element and cage collision 02 cage is used to correct the key role of guiding roller. The rolling element and cage collision is also a derived from noise. That collision include axial, axial, radial and its possible. Look from the motion state, contain inside the load zone, roller rolling body actively promote cage collision cases; In the load section maintains a promote rolling body case of collision. Because centripetal force effect on the shaft up roller and cage collision. Because of oscillation, radial movement and the roller cage collision, etc. Rolling body and grease 03 when bearing inside the filling grease, operation of the rolling element had a mixing of lubricating grease. This kind of mixing will also spread relative noise. Rolling body up and down the rolling friction 04 in the roller into the load of the situation and maintains a certain rolling friction. In access to load the case also is likely to see a certain level of rolling friction. The movement of the motor bearing internal 05 hydraulic seal bearing friction lip, also can produce noise. Overall, not too hard to find, all this in the operation of the rolling bearing in normal circumstances, is difficult to avoid causing some 'noise'. So the answer is: to start problem in view of the rolling bearing, its original 'all normal noise' is unlikely to clear. The above is the content of the author to share today, want to learn more bearing small knowledge, pay attention to the bearing's official website.
