Discussion Overview

The discussion revolves around the design and modeling of worm gears for an automated plant trimming device. Participants explore resources and information related to worm drive design, focusing on technical specifications and modeling techniques in Autodesk Inventor.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant describes their project involving automated snips and expresses uncertainty about accurately modeling a worm gear in Autodesk Inventor.
  • Another participant requests additional information to facilitate responses, indicating a lack of engagement in the thread.
  • A third participant provides a link to a technical document that covers various aspects of worm gear design, including geometry, calculations, and tooth proportions.
  • A final participant expresses gratitude for the assistance received in the thread.

Areas of Agreement / Disagreement

The discussion does not appear to have reached a consensus, as participants are still exploring resources and clarifying needs without definitive answers or solutions.

Contextual Notes

The initial participant's request for help indicates potential limitations in their understanding of worm gear design, and the responses suggest varying levels of engagement and expertise among participants.

Who May Find This Useful

Individuals interested in mechanical design, particularly those working with worm gears or using CAD software like Autodesk Inventor, may find this discussion relevant.

Hey guys!
I am currently creating some automated snips for trimming plants.
I am using auto desk inventor to design it all.
The design and concept is solid and modeled/animated to show proof of operation.
However now i want to try prototype - i can sort out everything aside from the gear.
I know my gear ratio, the diameter of both gears and the teeth number (so modulus).
Now i need to try see if i can actually accurately model the gear in inventor (currently just used a 1:40 worm gear that i fiddled to my required dimensions). However the issue is that i have no idea where to start learning!
Google hasn't been overly helpful in this scenario (or i just missed something good).

Any help or advice is greatly appreciated!

thanks a lot for taking time to read!
