Backlash and Tooth Contact between Spiral Bevel Gear and
Spiral Bevel Pinion Shaft
1. Set the dial indicator (lever type) with its finger on the tooth
surface.
2. Measure the backlash by fixing the spiral bevel pinion shaft (3)
and moving the spiral bevel gear (4) by hand.
3. When the backlash is too large, decrease the number of shims
(5) in the side of the spiral bevel gear, and insert the shims (6)
of the same thickness as the removed ones to the opposite side.
When the backlash is too small, do the opposite way of exceed
backlash.
4. Adjust the backlash properly by repeating the above procedure.
5. Apply red lead lightly over several teeth at three positions
equally spaced on the spiral bevel gear.
6. Turn the spiral bevel pinion shaft, while pressing a wooden
piece against the periphery on the spiral bevel gear.
7. Check the tooth contact. If not proper, adjust according to the
instructions next page.
