Planetary gear sets
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 extremely 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.
Program description
Find a planetary gearset: input of frame values
A mouseklick on “search“ shows all suitable solutions.
After double-clicking on one solution you see the most important geometry data.
( The user interface is customizable. )
Now it’s possible to calculate the founded
solution directly with Stplus.
Ngs
- create a STplus input file,
- save it in the STplus file system,
- prepare the STplus config file and
- start STplus for the calculation.
STplus
- calculate the gearset and
- write the output files.
Ngs
- read the output files and
- show the results under the „STplus results“.
The results read from the Stplus output files.
Optimisation: Currently to find optimal values for
- normal module
- addendum modification factor
- pressure angle
After the optimization run, Ngs shows the results as CSV text.
Unfortunately, currently no result evaluation is implemented. But it’s possible to present the output results very clearly in a spreadsheet.
