Arbitrary rotation angle ratio transmission device for watercraft rudder/wing rudder

Abstract

The invention provides a transmission device for any rotation ratio of shipping rudder / wing rudder. Both a main rudder reducer and a wing rudder reducer are arranged on an upper cushion block; the shaft of a main rudder drive motor and a main rudder shaft are mutually vertical; the shaft of a wing rudder drive motor and a wing shaft are mutually vertical; the main rudder shaft is fixed with the inner rings of a top bearing and an inner bearing; a bearing, the inner bearing and a driven sleeve wheel of the wing rudder are sheathed on the main rudder shaft; the drive gear of the wing rudder is arranged outside the driven sleeve wheel of the wing rudder; the driven gear of the wing rudder is arranged outside the drive gear of the wing rudder; the wing rudder shaft is arranged in the driven gear of the wing rudder; the driven gear of the wing rudder is fixed with the outer rings of the top bearing and the inner bearing; a transmission wheel of the wing shaft is arranged on a pedestal; thewing shaft is arranged in the transmission wheel of the wing shaft; the driven sleeve wheel of the wing rudder is connected with the transmission wheel of the wing shaft and the driven gear of the wing rudder. The transmission device of the invention leads the transmission of the wing rudder to be capable of separating from the limitation of the main rudder, improves the course control performanceof a rudder system, reduces the energy consumption, improves the reliability and improves the seaworthiness of a ship.

Description

(1) Technical field [0001] The invention relates to a propulsion device or a steering device of a ship. Specifically, it is a transmission device for joint control of ship rudder / wing rudder. (2) Background technology [0002] Two wings with the same aspect ratio and the same chord length, under the same angle of attack, the curved wing with camber has a larger lift coefficient than the wing with symmetrical section, because the effect of camber is equivalent to increasing Bigger angle of attack. The rudder / wing rudder is to divide the rudder into two parts, the main rudder and the wing rudder according to a certain ratio. Through the transmission device, an angle is formed between the main rudder and the wing rudder. In fact, it is to change a general streamlined rudder into a certain Cambered rudder. In a broad sense, wing rudders are equivalent to variable camber wings, which can provide greater lift at the same main rudder angle before the incoming flow separates, gre...

Problems solved by technology

However, its transmission mechanism is relatively complicated, and its structure is not very compact, so it cannot fully meet the requirements of improving the seaworthiness of ships.
