Abstract

In this paper, the issues that need to be taken into account when analyzing the vibration state of rolling bearings with the defect "wear of the inner bearing cage" are touched upon. A design diagram of rolling bearings and a diagram of the forces acting on the bearings during their operation in a screw compressor are presented. Studies of the vibration state of rolling bearings on an operating screw compressor at a real industrial facility have been carried out. Vibration measurements were carried out when the compressor was operating with new bearings and with workers on whom there was obvious wear of the inner cage. The effect of wear of the inner bearing cage on the vibration state of the screw compressor is shown. It is established that for this type of bearing defect, in relation to the object un-der study, when analyzing the vibration state, the use of direct autospectral parameters is ineffective. For the case under consideration, the most effec-tive are the parameters of amplitude and frequency modulation.
