The paper proposes a comprehensive model to predict the
skew movement of a roller in tapered roller bearings. Numerical
solutions are given on a LM48548/LM48510 bearing. The effect
of the shaft speed, ring misalignment, and lubricant temperature
on the roller skew angle is presented and compared to the experimental
data available in the literature. The results indicate that
the skew angle depends first on the misalignment angle between
the cup and the cone. The roller skew is also greatly influenced
by the traction at the roller-flange contact, the skew angle increasing
with the traction at this contact, and by the geometry of
the roller end.
