Abstract
A ball-CV style transmission suitable for use in a Positive Displacement Motor (PDM). A shaft provides shaft wings received into housing receptacles on a housing. A ball and a Torque Transfer Element (TTE) is interposed between each shaft wing and housing within each housing receptacle, with the ball received into opposing recesses preferably on the shaft wing and the TTE. The TTEs float within their corresponding housing receptacles so as to maintain torque transfer contact between all thrust surfaces during articulated rotation of the shaft with respect to the housing. The TTEs preferably float generally radially towards the shaft centerline as angular deflection increases during articulated rotation.
