Abstract
Изобретение относитс к вйброизмерительной технике и может быть использрвано дл диагностики состо ни опор турбомашин в процессе эксплуатации . Целью изобретени вл етс повышение точности при вы влении дефектов , св занных с изменением зазоров в опорах. Указанна цель достигаетс тем, что измер ют величину и скорость изменени амплитуды и фазы роторной гармоники от оборота к обороту При повышенном износе подшипников опор возникает прецесси ротора, котора приводит к изменению амплитуды и фазы роторной гармоники.The invention relates to a vibration measuring technique and can be used to diagnose the state of turbomachine supports during operation. The aim of the invention is to improve the accuracy in detecting defects associated with changes in the gaps in the supports. This goal is achieved by measuring the magnitude and rate of change of the amplitude and phase of the rotary harmonic from revolution to revolution With increased bearing wear on the bearings, a precession of the rotor occurs, which leads to a change in the amplitude and phase of the rotary harmonic.
