Help!!! We have a project going on in which the customer has been using Martin stock gears and worms, the gear is a 20T W1220, 12DP, 14.5 deg. P.A.. The matching stock worm is 1.166 O.D. with a 1.000 pitch diameter. The angle is 4 deg. 46 min. However, the customer is using a worm that measures 1.422 O.D.but he is using it with the 20T stock Martin gear. All my calculations show the angle changing to 3 deg. 48 min. How can I get the bigger O.D. and still match the angle of the smaller worm?
Thanks for any help...
