Abstract

The invention relates to an angular displacement sensor, belonging to a sensor for measuring rotating angle. The angular displacement sensor solves the problem that the existing rotary potentiometer is hard to install when in angle measurement, and comprises a fixed component and a rotating component, wherein the fixed component includes an insulating base body and a conductive carbon film layer, and the circular-arc-shaped conductive carbon film layer provided with a nick is adhered to the surface of the ring-shaped insulating base body; the two circular-arc-shaped ends of the conductive carbon film layer are respectively provided with a positive electrode and a negative electrode; a signal output pole is arranged at the position corresponding to the circular-arc-shaped nick of the conductive carbon film layer on the insulating base body, and is welded with a V-shaped copper probe; the rotating component includes an insulating ring, a copper ring and an electric brush, wherein the copper ring is embedded and sheathed at the outer circumference of the insulating ring, and provided with the electric brush. The angular displacement sensor has simple and compact structure, can be directly sheathed on a rotating shaft, does not need an extra special sensor mounting box, can work in high pressure hydraulic oil, and is especially suitable for joint rotation angle measurement of an underwater robot, an underwater engineering machine and other underwater equipment.

Description

technical field [0001] The invention belongs to a sensor for measuring rotation angles, and is particularly suitable for measuring joint rotation angles of underwater robots, underwater engineering machinery and other underwater equipment. Background technique [0002] In the existing rotary potentiometer used for angle measurement, the resistance body has two fixed ends. By manually adjusting the rotating shaft and changing the position of the moving contact on the resistance body, the distance between the moving contact and any fixed end is changed. The resistance value changes the magnitude of the voltage and current, and the output-to-input voltage ratio has a linear relationship with the rotation angle. The measurement of the joint rotation angle of the underwater manipulator is necessary for the servo control of the manipulator. When the existing rotary potentiometer is used to measure the rotation angle of the joint of the underwater manipulator in real time, its stru...
