Measuring Instruments for Gear Testing
Measurement of Tooth Span
Measuring tooth span enables indirect determination of the
tooth thickness. Contrary to the specific measuring of tooth
thickness, this procedure is performed totally without any
reference points. Tooth span dimension Wk is measured over a
specific number of teeth. The contact faces of the instrument are
placed one on the lefthand flank and one on the righthand flank
of the gear to be checked in the vicinity of the pitch circle (see
sketch on left). The number of teeth k, the instrument is placed
over, depends on the total number of teeth z and the pressure
angle α. Use formula (see page 8-4) for the determination of the
nominal dimension of tooth span Wk and number of teeth k .
For spur gears with straight teeth there are tables for the
determination of these two dimensions (for pressure angle
αn= 20° see page 8-4).

Formula for Calculating Tooth Span used for calculation of nominal dimensions of tooth span and number of teeth
The following relations are valid:
Wk = mn • cos αn[(k-0,5) • π+z • inv αn]+ 2 • x • mn sin αn
k=z•
αn
180
+ 0,5
x
= profile displacement
mn
= standard module
k
inv αn
= tan αn - αn(α in arch dimension)
z
= number of teeth of gear
αn
= number of teeth between
measuring faces
= standard pressure angle
Table of Tooth Span for gears with straight teeth and without profile displacement
Pressure angle αn = 20° module mn = 1
This table refers to module 1. In case of modules other than 1 the tooth span dimension Wk , which has been calculated, is multiplied
by the module of the gear to be checked. If a profile displacement occurs, value + 2 • x • mn • sin αn is added to tooth span dimension
Wk . In case of negative profile displacement, factor x must be designated as negative.
Explanation of symbols:
z = total number of gear teeth
Wk = nominal dimension
k = number of teeth in between measuring faces of measuring instrument

Measuring Instruments for Gear Testing
Checking of Pitch Circle Diameter
Measuring of the roller dimension MdR or ball dimension MdK of
gears enables indirect determination of tooth thickness. This
procedure is chosen mainly for narrow gears with helical teeth or
gears with large helix angles on which tooth span checks cannot
be performed. A measuring ball or roller is placed in two tooth
spacings which are opposite each other. The diameter of the
measuring ball or roller is such that it contacts the tooth flank in
the vicinity of the pitch circle where the involute error is at its
minimum and hardly influences the measuring results.
