METHOD OF DIAGNOSING BEARING ROLLING ELEMENT AND DEVICE FOR ITS EMBODIMENT Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: one of bearing races is rotated, bearing is loaded with radial load constant in value, and direction of radial load action is changed. In this case, value of integral parameter of relubrication intervals of every rolling element is measured, while aligning the direction of radial load action with center of rolling element being diagnosed. Quality of rolling element surface is estimated by deviation of integral parameter value measured for it. Device for embodiment above-mentioned method has electric voltage source which one pole is connected to bearing assembly shaft through pulse former and current collector, and other pole is connected to bearing outer race. Device also has counter connected to time selector output, reference-frequency generator, loading facility manufactured for kinematic coupling with bearing assembly shaft, as well as separator turn angle pickup, and univibrator. Loading control unit is introduced into device additionally. EFFECT: enhanced accuracy of diagnostics. 2 cl, 6 dwg
