DUAL STATION ROTARY CABLE STEERING SYSTEM

摘要

Disclosed herein is a steering system comprising a marine propulsion device including a rotatable member connected to a steerable part and effective to cause steering movement of the steerable part upon rotation of the member, a helm housing including a rotatable steering shaft, a first flexible cable including an outer sheath and a rotatable inner core, a first gear box connected to the outer sheath and to the marine propulsion device and including a rotatably mounted gear coupled to the rotatable member for common rotation therewith and a rotatably mounted pinion coupled to the inner core for common rotation therewith and in mesh with the gear, and a second gear box connected to the outer sheath and to the helm housing and including a rotatably mounted gear coupled to the steering shaft for common rotation therewith, and a rotatably mounted pinion coupled to the inner core for common rotation therewith and in mesh with the gear in said second gear box. Also disclosed herein is a gear box comprising a first housing member including a cup portion, and a transverse wall portion including a central aperture, and an exterior part of non circular cross section, a bearing located axially inwardly of the first housing member from the aperture, a second housing member including a cup portion telescopically engaged with the cup portion of the first housing member and a transverse wall portion spaced from the transverse wall portion of the first housing member and including a central aperture coaxial with the central aperture of the first housing member, and an exterior part of non circular cross section, a bearing located axially inwardly of the second housing member from the aperture of the second housing member, a gear rotatably supported by one of said bearings and including a central opening of non circular cross section, a rotatably mounted pinion in mesh with the gear, and means preventing relative rotation between the first and second housing members. Also disclosed herein is a coupling including a first member rotatably supported in a housing and including first and second coupling elements, a second member rotatably supported in the housing and including a third coupling element, and means connecting the first and second members for common rotation.
