Cylinder Gauges for Measuring Spline and Internal Gears


	For Peacock, measuring unusual places and shapes is never impossible.

Using specified ball diameters on both ends, we custom-manufacture
dial bore gauges for measuring pitch diameter.

For measuring root diameter, we remove the contact point guides
(centering mechanism) so the gauges will not touch either gear tooth
flank.

For measuring the inside diameter, we add contact point guides
(centering mechanism) to support the gauges on top of the gear teeth.

Measuring Pitch Diameter

Please specify pitch diameter and
ball diameter.
(Carbide material will be used for
all balls if not specified. For very
unique requirements, we some-
times ask customers to supply us
their own gauge balls.)

When gauge balls interfere with
tooth surface and invalidate the
measurement, we truncate both
balls.

We provide customized conversion
tables for applications with odd
numbered teeth.
(Individual conversion table is made
just for your application.)

* The diameter of these balls
is a key point.

* Both ball ends are truncated.

Measuring Large Diameter

Please specify large diameter
(ø D), width and height of face.
(We design contact points that do
not touch either gear surface.)

When the number of teeth are odd,
one side of the contact point is
bifurcated to straddle a tooth.

* Dimensioned the size of
contact point

* Contact points straddle a tooth

Measuring Small Diameter

Please specify inside diameter size
and whole depth of tooth.
(We design contact point guides on
both sides of contact point.)

Ball tip is used on contact point
guides.

For shallow spline and internal
gears.

These bore gauges for measuring
spline and internal gears are adopted
from CC series (standard bore gau-
ges). For measuring shallow spline
and internal gears, we adopt CG
series.

* Putting contact point guides against
the top of the teeth is the key.

* Ball tips avoid friction wear
