Spherical bearing raceway sound generated by the load source lies in the ring after the natural vibration due. Raceway sound is due to rotation of the spherical bearing rolling elements and the raceway scroll inspire a kind of smooth and continuous noise, only when its sound pressure level or tone when aroused great attention.
Since the elastic rings and rolling contact with nonlinear vibration system constituted. When lubrication or machining accuracy is not high flexibility with this feature will be excited about the inherent vibration transmitted into the air then becomes noise. As we all know, even with the highest levels of modern manufacturing technology machining spherical bearing parts, the work surface there will always be varying degrees of tiny geometric errors, so that between the raceway and rolling elements excite vibrations produce tiny fluctuations inherent in the system vibration.
Although the spherical bearing raceway noise is inevitable, however, precision machined parts can be taken to the work surface, the correct selection and precise use of spherical bearings, spherical bearings make noise damping.
