Calculation of vibroacoustic characteristics of a four-point ball bearing. Part 2

The paper presents the results of the calculation of noisiness of a four-point bearing depending on the accuracy of producing as a part of the product in which it works. The calculation was performed according to the methods and programs developed by the authors. The noisiness of the separator and the balls that exists when the bearing is placed in any kind of an elastic system is calculated. Natural frequencies of bearing elements are defined with a given load on it as applied to the vibration set. It is shown that the errors of bearing production result in parametric excitation of elastic systems and excite oscillations with natural frequencies in them which produce the greater part of noisiness both of the systems and the bearings.
