抄録

It is considered by experiences that a noise of fitted ball bearing is affected by many factors, especially the radial clearance and the race fitting. The author measured the noise of fitted ball bearing with known radial clearance and at several race fitting conditions under the radial load, analyzed the peak values of the frequency spectrums, and obtained the results as follows : -(1) the frequencies and the total sound pressure level of the noise decrease with the radial clearance. (2) The total sound pressure level of the noise is determined by the summation of some radial contact forces between the races and the balls and the size of the loaded zone. (3) The frequencies of the noise increase with the interference of the outer ring. But, the total sound pressure level increases with the interference of the outer ring in the case of small radial clearance, while it decreases in the case of large radial clearance.
