The
helical gear pairs are widely used in different mechanical constructs. The main
advantage is the good efficiency and the low noise during the connection.

We have
worked out a computer software with which the designing process of the helical
gears could be eased. Based on the calculated gear parameters the CAD models of
the elements could be prepared. Knowing of the geometries the assembly could be
created based on the fixed freedom degrees and the elementary centre distance.

We have
designed five types of gear pairs. The differences are only the different tooth
traces. All of other parameters have not been modified.

We have
done TCA which is meant we have analyzed the effect of the modified parameter
for the normal stress, normal deformation and the normal elastic strain on the
contact zone. Based on the results we have prepared diagrams for the analysis
of the correlations between the changing parameters.
