Abstract

This paper deals with failure diagnostic problems of vertical axis rotating machine driven by ten cycloidal gear reducers with high coupling ratio. The cycloidal gear drive is not back drivable device and in case of only one cycloidal drive failure from ten simultaneously running  it may cause serious failure  of expensive driven involute gear tooth. The main task of ten simultaneously running cycloidal gear reducers research - identification of vibration sources and determenation parameters in attempt to eveluate technical condition of  each cycloidal drive, especially technical condition of crankshafts eccentric antifriction bearings. Authors suggested effective cycloidal gear speed reducer main bearings high frequency vibration monitoring  procedure, based on long term research data provided in industry.
