Bearing ring natural vibration reason and processing

Bearing ring natural vibration causes and treatment: the natural vibration in the bearing ring and ball and the channel surface shape error, the inherent vibration of ring is the basic vibration of rolling bearings, can be divided into three categories: ( 1) Outer ring of inertia moment of related angular vibration mode; ( 2) The quality of outer ring axial vibration mode, 3) Bearing ring bending vibration mode. Even by modern processing technology made precision bearing, also is unable to avoid this kind of vibration. This kind of vibration is important, because it is similar to the noise of the bearing directly, especially related to the quality of outer ring axial vibration mode for bearing the resonant sound similar. Especially waviness are similar, it makes the bearing irregular fluctuations during operation, such a ring and ball contact elastic deformation occurs, the trace of changes to ring and the forced vibration of the vibration. To control the vibration, as long as the choose and buy low vibration bearings or indicators to the requirement of bearing waviness is put forward, to choose suitable lubricant, can help to reduce the vibration. Refers to the relative sliding friction between the surface abrasion failure lead to constant wear and tear of the working surface of the metal and the failure. Continuous wear will cause bearing parts damaged gradually, and ultimately lead to SKF bearing size accuracy loss and other related problems. Wear may affect the shape change, the increase of fit clearance and working surface morphology change, may affect the lubricant or make its pollution to a certain degree of lubrication function is lost, so that loss of bearing rotating accuracy and will not operate properly. Wear failure is one of the common failure modes of all kinds of bearings, according to the wear and tear is usually divided into one of the most common form of abrasive wear and adhesive wear.
