Re: Cam trigger
We are doing some preliminary calculations on the torque required to turn this cam. We picked out some springs (Lee Spring part # 177P 03 S), and did a feasibility calculation. We ended up with 32.17 N*m required to turn the cam a final increment as the spring is at nearly full extension. (80 lbs of force). See attached work. We assumed that the spring would be attached directly to the point where the Cam contacts the kicker arm, and that there is no friction.
Is this 32.17 N*m answer reasonable??? (lifting a bit more than half a robot) Thanks |
