Abstract
An offset shaft bearing assembly includes a drive shaft extending through an outer housing. The drive shaft centerline is at an angle to the centerline of the outer housing. The shaft is coupled to the outer housing by radiused conical bearings which act as thrust and radial bearings. At least one of the radiused conical bearings is offset from the centerline of the outer housing. The radiused conical bearings may include a curved bearing surface, allowing the radiused conical bearings to operate despite angular misalignment.
