Re: Gearing a Rotating Arm
careful with the versa planetaries. if you look at the published load specifications it says that a CIM on a 100:1 is well outside of the load limits for those gear boxes. Also your speed seems high. My team is doing a similar thing to you however our arm mass and length is larger. We plan on using two mini CIM's we will have a total of a 150:1 gear ratio. 50 of that will come from a 3 stage gem planetary then another 3:1 reduction by chain and sprockets. also be carefull with what you use as the axle. we are using a 1 inch aluminum pipe.
