Polygon universal joint

摘要

A universal joint adapted to interconnect a pair of rotating shafts at an angle relative to one another including a first member and a second member wherein the first member has a first longitudinal axis and includes an elongated semi-spherical head having a plurality of circumferentially spaced and radially outward facing facets which are curved along the first longitudinal axis and the second member has a second longitudinal axis and includes a pocket adapted to receive the elongated head. The pocket further includes a plurality of circumferentially spaced and radially inward facing facets which correspond to the plurality of radially outward facing facets on the elongated head and are tapered relative to the second longitudinal axis.
