TIMKEN bearing Raceway sound source is due to ring the inherent vibration after the load. Raceway as the TIMKEN bearings rolling body Raceway when rotating scrolling and fires in a smooth and continuous noise only when its sound pressure level or tone only when great attention.
Due to the rings and rolling elements of nonlinear vibration of elastic contact form system. When lubricating or when machining accuracy is not high stimulation and the inherent vibration of elastic features, passing into the air becomes noise. As we all know, even using the most skilled manufacturing technology and processing components of TIMKEN bearing, its surface will always exist with varying degrees of tiny geometric errors, so that between the raceways and rolling elements produce micro-wave excited vibration inherent vibration.
Although the TIMKEN roller bearing of the road noise is inevitable, however you can take high-precision machining parts surface, correct choice TIMKEN bearings and precise use of bearing making noise damping.
