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 Unitary Torque Transfer Element (UTTE) is interposed between each shaft wing and housing within each housing receptacle, with a spherical surface on the UTTE received into a recess preferably on the housing. The UTTEs 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 UTTEs preferably float generally radially towards the shaft centerline as angular deflection increases during articulated rotation.
