My knowledge in gears in limited to their types (bevel, spur, etc). I am trying to combine the power/torque of two DC motors using a differential gear.
The problem I am having now is finding the correct differential gear to use (in term of shaft size, etc).
For a PoC I don't mind using Lego or plastic. Eventually these two motors will connect via another differential to two other motors (which have their own differential) for a total of 4 to hopefully turn the drive shaft of this kettcar.
My overarching question is:
- How/where do I choose the correct differential to use?
- How do I scale up/down the motor's output shaft to fit into whichever differential gear I end up using?
As to "why" do this:
That said, if this approach is bat-crap crazy, then please feel free to say so and suggest an alternative.
