the only way we have figured to draw it in SW is to draw concentric circles for the minor and major diameter of the splines, do a circular pattern for each peak and valley, then connect them with an arc to create the curved face of each spline. we have all the dimensions as required by the machinist handbook for creating splines, but it does not translate to our solidworks knowledge. this allegedly will save us a lot of weight because the hubs are pretty heavy to start with and we have to leave a fair amount of material around the splines so they dont shatter after they are pressed into the spool.Īll that being said, we are having trouble drawing the splines so we can give a. this year we are trying a new approach machining a spool out of 4340 and then having the splines cut with an EDM. in the past we have just turned down a set of hubs that are already splined then pressed them into the spool housing and tigged them in. So, our Baja SAE team is running a spool that accepts polaris rear CV shafts.
