Abstract :
The basic parameters of the universal gear drives, except the axis height,
are not defined by the standard, so the manufacturers of universal gear
reducers can define them in their way. Most of the manufacturers followed
the parameter values of universal gear reducers of leading world producers
in order to ensure their interchangeability and the better positioning of
their gear units at the market. This paper deals with the analysis of the
influence of the gear pair teeth number on the size of the module, as well
as on the load carrying capacity of single-stage universal gear units. For
defined gear ratio values, different combinations of teeth number of pinion
and driven gear were selected. Further, it was made calculation of the basic
geometric dimensions of the gear pair, as well as the load capacity
