Pinion shaft and ring gear,
adjusting
Notes:
Careful adjustment of the pinion shaft and ring
gear is essential for the service life and smooth
running of the final drive. For this reason, the
pinion shaft and the ring gear are matched
together during manufacturing and checked to
ensure a good mesh pattern and quiet running
in both directions of rotation. The position of
quietest running is found by moving the pinion
shaft in an axial direction, and at the same time
lifting the ring gear out of the zero-play mesh
position by the amount necessary to maintain
the backlash within the specified tolerance.
The goal of the adjustment is to reproduce the
setting for the quietest possible running, as
obtained on the test machine during production.
The deviation, or tolerance "r" which is based
on the master gauge "R0" is measured for the
final drive sets supplied as replacement parts
and marked on the outer circumference of the
ring gear. The final drive set (pinion shaft and
ring gear) must only be replaced together as a
matched pair.
