Ship electric servo fin/wing optional-angle-ratio transmission device

Abstract

The invention provides a ship electric servo fin / wing optional-angle-ratio transmission device. When a main fin motor rotates, a cardan shaft handle of a main fin is driven to rotate; when the cardan shaft handle of main fin rotates counterclockwise, a pulling and pushing rod of the main fin drives a main fin swing arm to rotate counterclockwise to allow a main fin shaft to rotate counterclockwise, that is to say, a main fin blade rotates counterclockwise; when the main fin shaft rotates counterclockwise, a wing motor is driven to rotate, that is to say, a wing cardan shaft handle and a wing cardan shaft handle connecting lever rotate to drive a wing pulling and pushing rod, a wing rotating sleeve connecting lever is driven to drive a wing rotating sleeve to rotate, and a wing swing connecting lever is driven to swing and drive a wing slide rod and a wing slide rod dual-hole sleeve to swing. Since a wing shaft penetrates the main fin blade and is fixed to the wing slide rod dual-hole sleeve, the rotating angle of a wing blade is increased or decreased on the basis of an existing wing angle, and the wing blade is allowed to rotate without limit of the main fin blade. By the aid of the ship electric servo fin / wing optional-angle-ratio transmission device, the swing reducing capability of a fin stabilizing system can be improved greatly.

Description

technical field [0001] The invention relates to a ship device, in particular to an attitude control anti-rolling device for the ship device. Background technique [0002] In a certain range and at the same angle, the lift value that the fin stabilizer can achieve will increase with the increase of camber, and the lift-to-drag ratio will also be improved to a certain extent. Taking advantage of this characteristic, flap fins (fins / wing fins) of ships have been designed to improve the hydrodynamic performance of the fins. In a broad sense, the wing fin is equivalent to a wing with variable camber, which can provide greater lift at the same main fin angle before the incoming flow separates, which greatly improves the maneuverability and seakeeping performance of the ship. At the same time, at the zero position, the entire fin presents a symmetrical wing profile, which reduces resistance and ensures the sailing stability of the ship when sailing straight. Therefore, research on...
