Problems solved by technology

[0003] The fin angle transmission mechanism of the existing fin stabilizer device takes up a large space in the cabin and has many kinematic pairs, and it is easy to get stuck during use. Due to the fixed length of the rocker and connecting rod, the transmission angle can only be ±24° at most. It cannot adapt to the large angle (±60°) of the retractable full-speed fin stabilizer

Abstract

The invention relates to a large-angle fin angle conveying mechanism which converts linear displacement into angular displacement. The fixing mechanism of the fin angle conveying mechanism is articulated with the conveying mechanism of the fin angle conveying mechanism through a pin shaft. The conveying mechanism of the fin angle conveying mechanism is connected with the fin angle transmitter through a guide rod, and the fixing mechanism of the fin angle conveying mechanism is connected with the piston rod of the rotating fin cylinder through a connecting rod. A piston rod of a rotating fin cylinder drives a fixing mechanism of a fin angle conveying mechanism to move up and down through a connecting rod, so as to drive the guide sleeve cylinder block of the conveying mechanism of the fin angle conveying mechanism to rotate, the guide rod in the guide sleeve cylinder block is rigidly connected with the potentiometer of the fin angle transmitter, and the fin angle of the fin angle transmitter is changed through the guide rod along the movement length of the guide sleeve cylinder block, and the linear displacement of the fin angle transmitter cylinder is converted into the angular displacement. A ball guide sleeve is introduced to convert the linear displacement of the rotary fin oil cylinder into an angular position, and the transmission angle is determined by the length of the ball guide sleeve and the guide rod, so that the linear displacement of the rotary fin oil cylinder of the actuator is converted into an angular displacement.

Description

technical field [0001] The invention relates to a fin angle transmission mechanism of a ship, in particular to a large-angle fin angle transmission mechanism used for angle feedback of a retractable full-speed fin stabilizer device. Background technique [0002] The existing fin stabilizer device is equipped with a fin angle feedback mechanism on the oil cylinder, and the linear displacement of the rotating fin oil cylinder is converted into an angular displacement by using a rotary potentiometer. The connecting shaft of the feedback mechanism is installed in the screw hole at the upper end of the piston rod of the fin oil cylinder, and is integrated with the piston rod. The linear motion of the piston rod is transmitted to the rocker assembly through the connecting rod. The rocker assembly drives the cam on the fin angle transmitter to rotate, and then rotates the shaft of the rotary potentiometer to reproduce the angle information of the fin shaft, and the potentiometer f...
