AI Thread Summary
A user is seeking assistance in creating a CAD model for a type 3 epicyclic gear train, specifically a planetary gearbox with two rings. They express difficulty in the design process due to a lack of experience with physical reducers. The discussion includes a suggestion to ensure that at least two of the shafts are concentric during assembly. Additionally, a resource is mentioned that explains how to create a planetary gearbox using FreeCAD. The user is looking for CAD files, photos, or any relevant resources to aid in their project.

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):

This guy explains how to make a planetary gear box in FreeCAD.

 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
