TRANSMISSION ERRORS IN PRECISION WORM GEAR DRIVES

ABSTRACT
Transmission error is a measure of the positioning accuracy of a gear system. This
has been widely documented in gearing for many years as the source of problems in
noise and vibration. It is a result of errors in the contact conditions which affect the
driven gear with respect to the rotation of the driver gear. This research aims to
present a better understanding of the basic kinematics of worm gear systems by
identifying the significant influences which determine the contact conditions.
