blueberry01 Posted February 3, 2009 Posted February 3, 2009 Hi all, I am trying to cut 3 helical groves (each starting 120deg) apart and rotating around the cylinder for about ~270deg on the outer surface of a cylinder but I have no idea how to do it. The grooves will house a roller ring (geared on the outside to mate with a motor) and the purpose is to induce linear motion into a cylinder from rotary motion of the motor. Many thanks, P.B. Quote
shift1313 Posted February 3, 2009 Posted February 3, 2009 You can draw your cylinder, then draw a helix and use the helix as a path to sweep whatever profile you need to cut. If this idea would actually see combustion ill assume that you would maybe want a "V" groove for a tapered roller setup. I had a similar design a few years back but the approach was a little different. Quote
