Hello,
My team is looking into using a super shifter this year for our robot. This will be a new endeavor for our team and i had some questions. First, how does the gear shifting work/ are there more than 2 gears on the shaft than just high and low? Second, how many pistons per gearbox are needed? Third, is there anything less expensive than andymark?
Thanks for your help!
Take a look at the dewalt whitepaper: http://www.chiefdelphi.com/media/papers/1592
Andymark has the CAD assemblies and pictures online if you want to take a look at them. Basically, the gearbox shifts by pushing a dog gear into grooves on either a large gear or a small gear. This makes the engaged gear the one that transmits the torque and the other spins freely. You only need one piston for each the gearbox. Unless you make a custom shifter, i don’t know of any other place teams have gotten shifters other than the Dewalts (I don’t knowhow these compare with respect to cost or functionality).
Thanks so much!
