Description
The plugin creates planetary gears set with straight, helical, double helical (*) and herringbone (*) teeth. Models are created in a new document.
Available features:
- Module (m) <0.25, 20> [mm],
- Tooth view type: normal, axial,
- Pressure angle (α) <14.5, 25> [°],
- Clearance factor (cf) <0.1, 0.25>,
- Gears thickness (t) <1m, 50m> [mm],
- Teeth shape: straight, helical (right/left), double helical, herringbone,
- Helix angle (β) <10, 40> [°],
- Groove width (gw) <1m, t-2m> [mm],
- Groove depth (gd) <0, rf> [mm],
- Sun teeth number (zs) <8, 100>,
- Sun backlash (bs) <-0.2, 0.2> [mm],
- Sun profile shift factor (xs) <-1, 1>,
- Sun teeth direction: right, left,
- Planet teeth number (zp) <8, 100>,
- Planet backlash (bp) <-0.2, 0.2> [mm],
- Planet profile shift factor (xp) <-1, 1>,
- Number of planets (N) <1, limited by number of sun, ring teeth and free space between them),
- Ring teeth number (zr) <24, 300>,
- Ring backlash (br) <-0.2, 0.2> [mm],
- Ring profile shift factor (xr) <-1, 1>,
- Chamfers: none, both sides,
- Width factor of chamfer (fw) <0, 0.25>,
- Height factor of chamfer (fh) <0, 0.25>
- showing preview (none, 3D, 3D with descriptions (1)),
- showing estimated time (rounded up to first 10 seconds),
- showing progress with ability to cancel,
- save, load, autoload, reset parameters,
- creating shafts in a new document,
- adding joints (2),
- adding axes,
- info icon redirecting to the product's data (3),
- information about files used by the plugin ("Information" tab),
- link to the privacy policy
Execution of the plugin for small (ex. z12-18-48) takes about a half minute on i7/8GB RAM/512GB SSD computer. For a larger number of teeth, helical teeth shape, options with chamfers it can take a few minutes. During the operation a progress bar with the current step is visible. The process can be canceled.
Disclaimer:
The program doesn't check interferences automatically and doesn't perform any analysis of prepared components. Please make sure that the necessary check is done before releasing this onto production. Samples on how to perform interference, sections and motion analysis is presented on my YouTube channel.
(*) Non-separable sets can be manufactured by 3D printers (toys, proof of concepts).
(1) Additional parameters will be visible (they are also saved in the components properties):
Sun:
pitch diameter (d),
working pitch diameter (dw),
working pressure angle sun-planet (αw),
root diameter (df),
outside diameter (da),
center distance sun-planet (asp)
Planet:
pitch diameter (d),
working pitch diameter sun-planet (dwsp),
working pitch diameter planet-ring (dwpr),
working pressure angle sun-planet (αw),
root diameter (df),
outside diameter (da),
number of planets (N)
Ring:
pitch diameter (d),
working pitch diameter (dw),
working pressure angle sun-planet (αw),
root diameter (df),
outside diameter (da),
great diameter (includes thickness of ring) (dg),
center distance planet-ring (apr)
Land parameters: (properties of tooth’s head per gear, accessible only from component’s properties):
pressure angle at outside diameter (αa),
half of the top land angle at outside diameter (θ),
top land thickness (crest width) (sa)
(2) Formulas for defining motion link and performing motion analysis are available in the description of component - see the first video about the update,
(3) When you don't have permissions to the plugin directory this icon won't be shown but you'll read on the "Information" tab where the plugin directory is and what permissions you need to add.

Very well made, and comprehensive addon
Well worth the cost
This saved me a ton of time on a recent project. Thank you!
