Abstract:
The long-term operation of ball bearing leads to
the deterioration of lubrication condition, resulting in
starved lubrication, which intensifies the wear of
rolling body(RB). Accurately identifying this fault
has a significant impact on bearing condition
monitoring. In this paper, the wear of RB was
quantified by diameter difference, and the friction
between components was considered, the fault
dynamic model of RB wear under the condition of
starved lubrication was established. Simulation and
experimental results indicated that an increase in
starved lubrication could suppress the sliding effect,
but the increased friction would exacerbate the wear
of the RB; The fractional multiple of the rotation
frequency of the cage in the frequency domain could
be used as a basis for monitoring the degree and
number of RB wear. In addition, changes in the
degree of starved lubrication would directly affect the
rotation frequency of the cage. However, the
fractional multiple of the rotation frequency of the
cage could still be used to identify RB wear fault. The
proposal and validation of the model provide
valuable references for achieving precise monitoring
and qualitative diagnosis of bearings in actual
working conditions.
