In the beginning it was an idea:
To find easy and fast planetary gear sets.

Much more has become of it:
A very useful tool, which make the
finding of gear sets extremly easy
and made the calculation and
optimisation possible with STplus.

And we don’t want to keep this to ourselves:
we offer you to customise this tool
for exactly your tasks.

With the specification of the ratio
the software find all planetary gear sets
that are possible for this.

Methods of searching are currently

  • K* acc. Niemann / Winter
  • given center distance
  • what do you need?

For the operations of searching

  • requirements are
  • min and max teeth number for sun
  • min number of teeth for the planets
  • number of planets
  • torque of sun
  • speed of sun
  • b/d factor acc Niemann / Winter

For the found planetary gear sets are

  • Teeth number of the planets
  • Tooth widths
  • Pressure angle
  • Helix Angle
  • Normal module

currently changeable.

In addition, each wheel set with

  • normal module
  • profile shift factor
  • pressure angle

as variables optimisable.
