Patent number: 10988224Abstract: An electric actuator comprises a housing and an output shaft reciprocatingly received by the housing. There is a screw assembly disposed within the housing and coupled to the output shaft. The screw assembly includes a plurality of annular rollers and a central screw received by the annular rollers. The annular rollers are rotatable about the central screw. There is a motor which includes a stator and a rotor. The rotor has an inner bore which engages the annular rollers. Rotation of the rotor causes the central screw to translate axially relative to the rotor and the output shaft to reciprocate relative to the housing.Type: GrantFiled: October 8, 2019Date of Patent: April 27, 2021Assignee: Marine Canada Acquisition Inc.Inventors: Noam Dean Davidson, Ray Tat Lung Wong, Mark Isaac Dyck

Patent number: 10766590Abstract: An outboard motor includes a steering arm that turns around a centerline of a steering shaft together with the steering shaft, a steering actuator including a movable body that moves in a right-left direction, and a motion converter that converts a movement of the movable body in the right-left direction into a turning motion of the steering arm around the centerline of the steering shaft. The motion converter includes a bushing holder into which the steering arm is inserted in a front-rear direction and a bushing interposed between the steering arm and the bushing holder and including an outer surface provided with a pair of first sliding portions each including a convex arc-shaped vertical section that is perpendicular or substantially perpendicular to the right-left direction.Type: GrantFiled: May 13, 2019Date of Patent: September 8, 2020Assignees: YAMAHA HATSUDOKI KABUSHIKI KAISHA, MARINE CANADA ACQUISITION INC.Inventors: Morihiko Nanjo, Noam Dean Davidson, Richard Tyler Redfern, Mark Isaac Dyck, Eric B.

Patent number: 10696368Abstract: An inner circumferential surface of a clamp bracket is open at an inner side surface of the clamp bracket. At least a portion of a movable body is surrounded by the inner circumferential surface in a side view. The movable body is movable to a plurality of positions including a position above a swivel bracket and a position inside a space surrounded by the inner circumferential surface of the clamp bracket. A steering shaft rotates around a steering axis along with movement of the movable body.Type: GrantFiled: May 13, 2019Date of Patent: June 30, 2020Assignees: YAMAHA HATSUDOKI KABUSHIKI KAISHA, MARINE CANADA ACQUISITION INC.Inventors: Makoto Mizutani, Morihiko Nanjo, Noam Dean Davidson, Ray Tat Lung Wong

Patent number: 10647399Abstract: An electric actuator for imparting steering movement to a propulsion unit of a marine vessel includes a housing and an output shaft reciprocatingly received by the housing. There is a motor disposed within the housing. The motor has a rotor assembly and a stator. Rotation of the rotor assembly causes the output shaft to translate axially relative to the rotor assembly and causes the output shaft to reciprocate relative to the housing. There is a coupling assembly mounted to the housing. The coupling assembly coupling the electric actuator to the propulsion unit of the marine vessel. There is a steering control unit mounted to the housing. The steering control unit drives the motor to cause the rotor assembly to rotate and the output shaft to reciprocate relative to the housing.Type: GrantFiled: May 14, 2018Date of Patent: May 12, 2020Assignee: Marine Canada Acquisition Inc.Inventors: Noam Dean Davidson, Richard Tyler Redfern, Edmond Adeeb Elia Astafanus, Eric B.
