Description

 

The application creates planetary gears for various set of parameters and automatically groups operations on timeline for sun, planet(s) and ring.

 

At this moment you can set:

  • module,
  • pressure angle (14.5, 17.5, 20, 22.5, 25 degrees),
  • clearance factor (0.188 or 0.25),
  • teeth shape (straight, helical, herringbone),
  • sun teeth number,
  • sun backlash (as arc length),
  • sun profile shift coefficient factor,
  • sun teeth direction (option in case of helical and herringbone),
  • planet teeth number,
  • planet backlash (as arc length),
  • planet profile shift coefficient factor,
  • planets count (also possible numbers),
  • ring teeth number,
  • ring backlash (as arc length),
  • ring profile shift coefficient factor,
  • adding chamfers (option),
  • width factor of chamfer (fraction of module),
  • height factor of chamfer (fraction of module),
  • showing progress (option).

 

All backlashes are as length of arc in mm. At this moment there's no checking of interferences (involute, trochoid, trimming).

 

Execution of plugin takes about half minute for small (ex. z10/z30) shafts on i7/8GB RAM/512GB SSD computer. If the option "Show progress?" is off and you don't see any effects for a minute, don't be a worry. There's also a standard Fusion progress bar in the lower right corner of the application and you can see if the plugin works.

 

Disclaimer:

Please make sure that the load analysis is done on gears designed by this plugin in real machines before releasing to production. An additional check is needed especially in case of undercuts:

  • section analysis,
  • interference analysis,
  • load analysis,
  • joints and motion simulation.

 

If you want to manufacture and use gears designed by this plugin in real machines, remember that they can break during load and cause damages, severe injuries or death of people without tests.

A propos de cette version

Version 1.0.6, 27/09/2019
**Version 1.0.6 (2019-09-12):** Fixes: * geometry errors in case of merging bodies for big gears **Version 1.0.5 (2019-09-08)** Fixes: * plugin hasn't stopped after clicking "Stop" in AddIn window **Version 1.0.4 (2019-09-05):** Fixes: * numerical instability, * better parameters validation. **Version 1.0.3 (2019-09-05):** Changes: * Added tooltips Fixes: * bug with calculating profiles **Version 1.0.2 (2019-09-03):** Fixes: * text about odd placement of planets **Version 1.0.1 (2019-09-03):** Available settings: * module, * pressure angle (14.5, 17.5, 20, 22.5, 25 degrees), * clearance factor (0.188 or 0.25), * thickness of gears, * the shape of teeth (straight, spiral - left/right hand, herringbone - left/right hand), * OPTION: helix angle (for helical and herringbone), * number of sun teeth, * sun backlash, * coefficient factor of profile shift for sun tooth, * OPTION: hand direction (left (L) or right (R) for helical teeth) * number of planet teeth, * planet backlash, * coefficient factor of profile shift for planet tooth, * Number of planets, * number of ring teeth, * ring backlash, * coefficient factor of profile shift for ring tooth, * ring backlash, * OPTION: adding chamfer for tampering inner and outer teeth edges, * OPTION: chamfer width factor * OPTION: chamfer height factor * OPTION: show progress mode for tracing execution. All backlashes are radial. Their values mean length of arc per tooth's side. Planned features: * the proper shape of gear when teeth are helical, * auto-setting profile coefficients, * improving performance, * graphics, * tooltips.
