INTRODUCTION
Gear inspection different methods are used
for identify good quality gears to be used in any
industry that manufacture gear or use gears in
their fi nal products.
Methods of Gear Inspection :
a. Double Flank Rolling Tester : The
composite test of a gear is a method of
inspection in which the work gear is rolled in
tight double fl ank contact with a master gear.
The composite action test is made on an
inspection instrument that will allow variation in
the center distance during rolling. This variation
in center distance will yield a tooth-to-tooth
(fi ”) and a total composite error (Fi”) indication
that can be read on a simple dial indicator or
recorded graphically.
Composite inspection is a useful shopfriendly
tool to determine the general quality
of a gear including size, run out, tooth-to-tooth
rolling action, and to detect nicks.
