I am sure you have used the one speed transmission supplied in the kit of parts. The kit of parts uses 4 CIM motors. The windshield motor, I am guessing you are talking about the window motor. the window motor has a gear attached to it. It also has 3 holes which are tapped so you would be able to mount it. Gears and sprockets can be found and ordered on www.mcmaster.com ... I don't know how well this might work but I would machine a shaft that would fit onto that gear. I couldn't think of the word. But like Matt said, "Its like a planetary with the sun gear meshing perfectly in to the gear on the window motor." |
The best think I've ever done with a window motor...
We needed to mount a sprocket to the window with general ease. I felt it would take too long to make a part to fit onto the wierd 9 tooth gear, and it would be too big. Soo... I take the gear off, stick it on a lathe, and cut the teeth off using carbide tooling. And what did I have left, after a little millwork? A half inch shaft with a notch in it, perfect for a sprocket and set screw.
By the way, this motor was used on team 115 MVRT's 2004 season swivel drive. Any machining questions on how to do this, pm me! Its easy, any metal lathe can do it, as long as you have a carbide insert facing tool. Heck, if your team is close to me I'll lend you one if you need it.
