METHOD FOR DIAGNOSTICS OF ANTIFRICTION BEARING RACES Russian patent published in 1997 - IPC

FIELD: measurement technology. SUBSTANCE: one of lubricated bearing races is rotated at working speed with the second race fixed. Rotating race unbalance is created, and integral parameter of bearing relubrication intervals for every tested raceway of fixed race is measured. When performing every measurement, integral parameter is determined in periods of time when vector if radial load caused by unbalance passes through angular sector from position of center of one and the same raceway section of fixed race relating to given measurement only. Deviations of parameter for every raceway section from the smallest value are used to determine quality of this section surface. Number of raceway sections of race under test is selected multiple from definite condition. This allows determination of fixed race defects during functional diagnostics of bearing in subassembly. EFFECT: higher efficiency. 2 cl, 4 dwg
