Motor Pinion Gear for Power Wheels Gearbox by hwswfun

Last crawled date: 3 years, 5 months ago

I used the gearboxes from PowerWheels kid ride toys for a robot. I wanted to swap out the stock motor with a hobby RC Car motor so I could easily control it with a speed control. This gear fits the hobby motor and has the same size/count of teeth as the original motor pinion gear.
The OpenScad file .scad creates the gear teeth and dimensions. Then I used Sketchup to modify it to have the flat part for the motor shaft.
The motor and speed controller I used were:
Hobbywing QUICRUN Series 860 Dual 60A Waterproof Brushed Electronic Speed Controller ESC
Goolsky AUSTAR 540 55T Brushed Motor.
While driving our robot outdoors for an extended time, The motor shaft eventually tore out the inside of the gear so you may want to consider ways to make the shaft bore stronger such as more shell layers. As for me, I just reprinted it:).
I am using this for our initial Snow Removal Robot
