A marine propulsion direction control device

Abstract

This utility model relates to the field of propeller direction control technology, specifically a marine propeller direction control device, including a protective cover, a mounting plate, a rudder stock, and a rudder blade. The marine propeller direction control device has a cylindrical body, and the mounting plate and protective cover are installed inside the cylindrical body. A servo motor is mounted on the top of the mounting plate via a mounting base, and the output shaft of the servo motor is fitted with a driving helical gear. The rudder stock is fitted on one end of the mounting plate via a bearing, and the top of the rudder stock is fitted with a driven helical gear. A positioning bushing is installed at the bottom of the cylindrical body, fitted around the rudder stock, and connected to a flared opening welded to the bottom of the positioning bushing. An inner ring is provided on the top periphery of the sealed chassis, and the inner ring is located inside the flared opening and fits tightly. The marine propeller direction control device automatically controls the rudder blade to change direction, thereby controlling the ship's course, effectively limiting the rudder stock, making it rotate stably, and reducing sway.
