Assessment of the lubrication condition of a bearing using spectral analysis of the stator current. ... Bearing lubrication assessment using an statistical analysis of the stator current spectrum.

Lubrication condition – the viscosity ratio,

The higher the κ value, the better the lubrication condition of the bearing and its expected rated life. This must be judged against the possible friction increase because of the higher oil viscosity. Therefore, most bearing applications are designed for a lubrication condition ranging from κ 1 to 4 .

Failure mechanisms of ball bearings under lightly loaded .

Fig. 2 is a schematic of the test setup. Axial and radial loads of 0.39 N and 0.70 N were applied to the ball bearings. The equivalent radial load (1.17 N) under this loading condition was only 0.7% of the static radial load rating (179 N) of the bearing, and was below the fatigue load limit (8.14 N) of the bearing .Thus, the ball bearings were lightly loaded throughout the tests.
