322 Three speed transmission.

[dkeith]

Here is a screen shot from AutoCad inventor. This picture shows the motor mount case and the gear configuration. All the case does is let me fit the motors in the robot. The transmission was wide enough that the motors had to be placed parallel to the transmission. The large gear is used to transmitt the motor power to the transmission while keeping the motor clear of the transmission case. The stepped piece is the Attwood gear drawn with no detail to make the design go quicker. The gear shown closest to the camera is the transmission input gear.
Yes, I have prints for everything drawn in Autocad Inventor. This is a very nice program. Inventor allowed me to turn gears and move shifters and see what would happen as well as keep track of weight. I had used Unigraphics before so the transistion to this 3-D package when fairly smooth.
