I am building a robot for a design class. Part of the design includes a wheel base to drive the robot forward. To accomplish this I was going to attach a spur gear system to a wheel axel and drive the input gear with an electric motor. The gears themselves will be made out of acrylic and cut out via a laser cam so I have a lot of options as far as how I make it. My question relates more to the design of the spur gears. I would like to know if the number of teeth that the output gear has, will in anyway impact on the speed/torque of the axel. Also while I know a greater diameter will allow for greater torque on the output gear it will also require the input gear to have a greater diameter which means more "back torque" on the input gear. Is there a way to figure out the ratio of diameters that will give me the greatest amount of torque? My goal is to get this to go as fast as possible with the given motors that I have.
