Formulas given in this chapter are only for reference and description of the adopted algorithms. Basic kinematic scheme of the planetary transmission is shown in figure .
Figure: Kinematic scheme of the planetary transmission
Numbered components in figure are:
There are several transmission ratios for different mounting and
variants which is shown in table where
Table: Transmission ratio as function of drive combination
The most common variant is Sun - Ring - Carrier. Other
connections are also used. Number of teeth is tested with the
following equation
where must be whole number.
