Re: [SeattleRobotics] Problems in Timing Belt drive system in 6WD robot
- Alan,I ran into this problem with tensioning arms, even when I had two tension arms (one for each direction). The motor would change direction too fast and the slack that the tensioning arm was taking up created a higher chance for one of the teeth to bind and cascade through as the direction of travel was maintained. Sometimes it would come off, sometimes it would drop back on. When it dropped back on it would click and pop. I think you need to have enough tension so that you don't need a tensioning arm.-XandonOn Jan 25, 2013, at 8:31 PM, KM6VV wrote:
Thanks. I'm still not finding the exact motor,
but I get the idea. 45 oz-in 142 RPM ??
my 10 kgf-cm = 138.873866 oz-in. So maybe I've just got too much
torque? I like my ground speed so far, should be 6-7 MPH with the
1:1.533 gears I have. 1:1 gears would give me about 4.5 MPH.

Drive pulley is 15 tooth and main pulley 30 tooth.
