I *THINK* if you incline your resolver gear you can use a straight cut gear. IIRC, the sum of helix angles must add up to the shaft angles. In your picture the shaft angles are 90deg so one helix is something like 80deg (the large gear) and the other is 10deg (the small gear). You can do the same w/ a 80deg and 0 deg if you incline your resolver 10deg. Is there a need to mount the resolver exactly vertical?
Makes cutting the gears really easy. The large gear can be cut w/ a form tool on a lathe just like you were cutting any other screw and the little one can be easily bought (or cut using conventional gear cutter and indexer) On Mon, Dec 7, 2015 at 11:17 AM, andy pugh <[email protected]> wrote: > On 7 December 2015 at 15:54, Sarah Armstrong > <[email protected]> wrote: > > how did your cad turn out > > > > https://picasaweb.google.com/lh/photo/jQREjwevQMPSQyyJspt0wtMTjNZETYmyPJy0liipFm0?feat=directlink > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto > > > ------------------------------------------------------------------------------ > Go from Idea to Many App Stores Faster with Intel(R) XDK > Give your users amazing mobile app experiences with Intel(R) XDK. > Use one codebase in this all-in-one HTML5 development environment. > Design, debug & build mobile apps & 2D/3D high-impact games for multiple > OSs. > http://pubads.g.doubleclick.net/gampad/clk?id=254741911&iu=/4140 > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
