Note: Gear transmission factors are rounded in many cases and may result in
a "drift" in the application, i.e. due to the rounded values, the deviation
between the actual position and the required position increases with
each revolution. This particularly affects rotary table applications which
turn in one direction continuously because their position change con-
tinues to increase all the time. Use exact gear transmission factors in
order to eliminate this drift. The exact gear transmission factor can be
calculated from the number of teeth of the individual gearwheels.
Example: Calculation of gear factors
Example: Three-stage gearbox
(i = 67.7 rounded) at reduction
gearing of 3:1.
Number of teeth:
D1 = 13
D3 = 12
D5 = 11
V1 = 1
D2 = 25
D4 = 27
D6 = 31
V2 = 3

Gear Box: Driving shaft revolutions 1116
= D2 x D4 x D6 x V2
= 25 x 27 x 31 x 3 = 62775
Gear Box: Motor shaft revolutions 1117
= D1 x D3 x D5 x V1
= 13 x 12 x 11 x 1 = 1716
