Coaxial shaft

thingiverse

Coaxial shaft assembly is not independent model it is part of future robot design but is stored independently on Thingiverse. Purpose of this design is to integrate two coaxial independently powered shafts in one mechanism. For example: One drive wheel second drive fliper. This is first prototype. ###BOM COTS: JGA25-371 - 25 mm diameter motor with gearbox and encoder 10x15x4 6700 bearing 20x27x4 6704 bearing key printed parts M1 16z 30deg bevel gear M1 40z 60deg bevel gear ### STL export resolution: **1 um** Resolution setup in FreeCAD: 1.
