I worked out the larger pics hot link
Half way through the track links for one side today.
I have also been trying to work out the drive train
printed a motor mount as a prototype to hold the 2 motors at the right angle to the drive shafts. I put the motors on an angle pointing at the axle so I would have to add in another set of gears before it turned 90 degrees. I have a 1:1 mitre gear set to get it to the sprocket.
I am actually surprised how strong this plastic is (ABS) and have changed my mind that I might as well leave it in and see how it goes. This also led me to try the speed of the motors and sprocket as a test. The motors are rated at 24v and run at 41 rpm. aAfter testing them on a 9 v battery ( 16 rpm) I have decide that I will have to somehow get a 2:1 ratio before it get to the sprocket. I am thinking 20 RPM would be an ideal speed - has anyone had any experience in this?
thanks
