DEVICE FOR DIAGNOSTICS OF ROLLING BEARINGS Russian patent published in 1998 - IPC

FIELD: measurement technology, mechanical engineering. SUBSTANCE: device is intended for test and prediction of state of rolling bearings under conditions of known type of wear-out. It has driving shaft, two current collectors, registering equipment and source of electric voltage which one pole is coupled via first current collector to driving shaft and which second current collector can be connected to outer race of bearing. Device is also fitted with integrator and degree converter which one input is connected to second pole of source of voltage, which second input is connected to second current collector and output is coupled to input of integrator. Registering equipment is connected to its output. Values of index of conversion function can be adjusted in degree converter which increases accuracy of diagnosis. EFFECT: increased accuracy of diagnosis. 1 cl, 1 dwg
