The invention discloses a gear shifting device and a ship propeller. The gear shifting device comprises a clamping component, a clamp base, a gear clamping frame and a gear shifting piece. The clamp base is used for installing the ship propeller, the clamping component is rotationally connected with the clamp base, the clamping component is used for fixing the ship propeller to a ship, and the clamping component is provided with a plurality of clamping parts. The gear clamping frame is rotationally connected with the clamp base, the gear clamping frame can move to different clamping portions and be clamped with the clamping portions in the rotating process of the clamping component relative to the clamp base, and when the included angle between the gear clamping frame and the clamp base is larger than a first angle, the gear clamping frame can cross any clamping portion. And the gear shifting piece is arranged adjacent to the gear clamping frame, and the gear shifting piece is used for pushing the gear clamping frame to enable the gear clamping frame to rotate relative to the clamp base, so that the included angle between the gear clamping frame and the clamp base is larger than a first angle. In this way, the gear shifting device can achieve cross-gear adjustment through the gear shifting piece.
Description
technical field [0001] The present application relates to the technical field of marine machinery, in particular to a gear shifting device and a marine propeller. Background technique [0002] Marine propulsion is a propulsion device attached to the rear side of the ship, and most of them are suitable for small and medium-sized ships such as speedboats or rubber boats. Marine propulsion mainly includes main engine, control device and power source. According to the power source, marine propulsion can be divided into electric type and fuel type. The main engine includes a gear shifting device and a propeller. When the marine propeller is used, the main engine is fixed on the ship through the gear shifting device, the propeller is located underwater, and the propeller rotates to generate propulsive force, thereby propelling the ship forward. The user changes the magnitude and direction of the thrust of the propeller through the manipulation device, and then steers the boat. ...
