How would you put 2 fisher price or 2 globe motors into a single gearbox? We are trying to get the fisher price into a very small gearbox (planetary) and need the motors to face the same direction. How have teams done this successfully in the past?
You need to replace the sun (the pinion on the motor placed in the planetary) with another gear. Then drive that gear with a seperate gearbox that links the two motors to a single output. This could be as simple as a single larger gear linked directly to the input of the planetary, driven by both motors.
