Abstract

A fin-angle feedback device comprises a fin stabilizer, a feedback main body and a coupler, wherein the feedback main body comprises a housing, a potentiometer, a pointer and a transmission rod, wherein a notch is formed in the side wall of an upper end shaft sleeve of the coupler; the upper end shaft sleeve of the coupler penetrates a mounting opening in a baseplate to extend into an accommodating cavity of the housing; a shift lever of the transmission rod is clamped into the notch; the feedback main body is fixed to the fin stabilizer through a flange plate; a lower end shaft sleeve of the coupler is fixed to a fin shaft of the fin stabilizer in a sleeving manner. The fin-angle feedback device is simple in structure; all components of the feedback main body can be mounted on the housing of the feedback main body, so that the feedback main body can be assembled into an independent whole; the fin-angle feedback device is convenient to assemble and suitable for batch production. A mounting method of the fin-angle feedback device comprises the steps of assembling components into an integral feedback main body and then the feedback main body is directly mounted on the fin shaft through the coupler. The assembly process is simple, and the assembly time is helped to be shortened during batch production of the fin-angle feedback device.

Description

technical field [0001] The invention belongs to the field of fin stabilizer equipment, in particular to a fin angle feedback device. Background technique [0002] The stabilizer fins are installed in the bilge of the two sides of the ship, and the section is wing-shaped, also known as side rudder. The fin stabilizer is rotated by the operating mechanism, so that the water flow exerts force on it, thereby forming an anti-rolling moment and reducing the sway, so as to reduce the roll of the hull. The fin stabilizer is composed of three parts: actuator, hydraulic system and control system. Among them, the control system generally adopts the fin angle feedback control method. [0003] The traditional fin angle feedback device includes a fin stabilizer, a feedback body and a coupling; the shell of the feedback body is installed on the fin stabilizer, and the feedback body includes a shell, a dial, a pointer, a potentiometer, a proximity switch, etc. Among them, many parts of t...
