I'm trying to model a sliding safety gate/door that is lifted like a guillotine. One end of the chain is fixed to the top of the machine while the other is to the top of the sliding gate/door. A pneumatic cylinder with a stroke of about 27" moves back and forth and lifts and lowers the gate (as shown in the sketch below)
The chain is ASA 50 and all the spur gears are about 4" dia.
My goal is to have the chain in place and to move the cylinder back and forth and have the door go up and down with it. I followed the tutorial here (SOLIDWORKS 2015 - Chain Component Pattern - YouTube ) for working with movable chains but can't seem to get the movement in both y and z.
I think it has to do with the way I have the sketch anchored but I'm so new to modeling chain movement I cannot tell. Can I get some help here?
