METHOD FOR VIBRATORY DIAGNOSTICS OF LOW-SPEED LARGE-DIMENSION ROLL BEARINGS

摘要

A method for vibratory diagnostics of low-speed large-dimension roll bearings includes rotation of bearing with following determination of its defects and degree of development of those by peaks of spectrum of signal from detector. The bearing is placed at test bench in assembly with cushions and working shaft, the journals of that are fixed in fixation equipment of the test bench. Determination of defects and the degree of development of those is additionally carried out by root-mean-square value of vibration velocity, by value of high-frequency detection of envelope curve and the value of vibratory acceleration in peak.
