Multi-gear drive tail vane

Abstract

The invention discloses a multi-gear drive tail vane which comprises a main blade, a driven blade and a tail blade. Transmission gears are arranged on the main blade and the driven blade, a connecting shaft gear on each blade is connected and fixed to a shaft, the shaft on each blade is fixed to a front blade and is non-rotatable, a driving gear on the main blade produces a torsion through rotation, drives the main blade to rotate and meanwhile transfers the torsion to the driven blade and the tail blade through the transmission gear, the transmission gears fixed to the driven blade and the tail blade and a tail moving gear utilize the torsion transmitted by the transmission gears through rotation to act on the shaft and the previous fixed connecting shaft gear so as to drive the driven blade and the tail blade to rotate, the specification differences of the gears form angle differences during rotation of each blade, and a curved vane blade is formed through the angle differences of the blades on the vane blade. The curved vane blade is higher than an existing linear vane blade in efficiency and makes ship control more stable, and a more scientific choice is provided for the ship tail vane.

Description

technical field [0001] The invention relates to a ship stern rudder technology, in particular to a multi-plate gear driven stern rudder. Background technique [0002] In the navigation of the ship, the course control is very important. The course control is mainly realized by the stern rudder. The reaction force generated by the contact between the stern rudder blade and the water controls the direction of the ship. The efficiency of the force between the rudder blade and the water body And the way directly affects the control of the ship. Factors such as the angle between the rudder blade and the water in the rudder blade directly affect the overall performance of the ship. The existing rudder blades are all single-piece structures. The rudder shaft is driven by the steering gear, and the rudder shaft controls the rudder blade.

Problems solved by technology

[0002] In the navigation of the ship, the course control is very important. The course control is mainly realized by the stern rudder. The reaction force generated by the contact between the stern rudder blade and the water controls the direction of the ship. The efficiency of the force between the rudder blade and the water body And the way directly affects the control of the ship. Factors such as the angle between the rudder blade and the water in the rudder blade directly affect the overall performance of the ship. The existing rudder blades are all single-piece structures. The rudder shaft is driven by the steering gear, and the rudder shaft controls the rudder blade. (single-piece rudder), because of the need for control, a single rudder can only be made into a straight line, and cannot realize the transformed curve control. The efficiency of curve control in water is more scientific than that of straight line control

Because the existing rudder blades are all single-piece, the effect of curve control in the water body cannot be realized. The main problem of the straight line control of the water body is that the efficiency of the rudder system is not high, which has a great impact on the water body, and the control stability at high speed is poor.

[0003] The current single-piece rudder has a non-streamlined effect on the ship through the water body, and the control is relatively rigid. Because the rudder itself is straight, it cannot achieve streamlined control. The efficiency of straight-line control and streamline control is different, and the stability is also limited. However, if streamlined control can be achieved, the efficiency of the rudder system and the stability of control can be improved
