Periodic Noise in Bearings 690756

In general, noise within an antifriction bearing can be classified as coming from random and periodic sources. The most annoying and preventable come from periodic causes, for example, a nick on a bearing raceway due to handling damage during assembly.As an aid in detecting such periodic sources in a tapered roller bearing, formulas are provided which determine the rate of contact for a specific point on one of the raceway surfaces, that is, cup, cone, or roller. Some experimental evidence demonstrating the worth of such an approach is included.
