Discussion Overview

The discussion revolves around the design of a type 3 epicyclic gear train, specifically focusing on the creation of a corresponding CAD model. Participants are sharing resources and insights related to the design process, including requests for CAD files and visual references.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant expresses the need for resources such as CAD files or photos of similar reducers to aid in their design process.
  • Another participant inquires whether the project is for schoolwork, indicating a potential educational context.
  • A suggestion is made regarding the necessity of ensuring at least two shafts are concentric in the design, with a reference to a video for assembly guidance.
  • A later reply reiterates the initial request for resources and mentions a specific tutorial on creating a planetary gearbox in FreeCAD.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are providing various suggestions and resources without a clear agreement on the best approach or solution.

Contextual Notes

The discussion may be limited by the participants' varying levels of experience with CAD modeling and physical reducers, as well as the absence of specific details about the design requirements.

Hello everyone,


As part of a project, I have designed a type 3 (with two rings ) epicyclic gear train. I now need to create a corresponding CAD model. However, since I have never seen an actual physical reducer, it makes the design process more challenging.

If anyone can help me with a CAD file, a photo of a similar reducer, or any other resource, I would be very grateful.

Thank you in advance for your assistance!

Is this project for schoolwork?
 
You must set at least 2 of the shaft concentric (one going through the other). It doesn't matter which one is inside the other. If they all go on the same side, all 3 must be concentric as in this next video (you can see how it is assembled at 0:24):
