‘Tha shaft required for this application was s stusdy, nos -bucbring de
‘ign made from S-in FB asd machined end plates (Figire 5). Since the
typical anticipated application weulé requize tention strassas rather
‘then compression forces, we set out to design & pump shaft which could
‘ve constructed inexpeusively using off-the-shelf components. the pri-
mmery design criverio were: (0) ability to withstand tension stresses
din excess of 500 Ibs, (2)! ability to adept simply to crankshaft beerines
on top, and polish rod on pump below, (¢) ineosyoration of a sxivelTing
capebility to accomodate the wind rotor! yaw response to changing
wind Sixections, and (2) ability to accomodate a stuple pump rod guide
