Background
When an input end transmission shaft drives an output device (such as a control surface, an adjustment sheet and the like) to deflect through a certain transmission mode (such as a steel cable soft transmission system, a pull rod rocker arm hard transmission system and the like), the following method is generally adopted for measuring the deflection angle of the output device:
1. sensor measurement

Detailed Description
Referring to fig. 1 to 8, the angle measuring and indicating device based on the archimedes spiral disc is composed of a hand wheel 1, a spiral disc 2, a pointer assembly 3, a support 4, a transmission shaft 5 and an angle engraving plate 6. When the hand wheel is installed, the groove 9 on the hand wheel 1 is tightly embedded with the flange 12 on the spiral disc 2, so that the hand wheel 1 rotates to drive the spiral disc 2 to rotate; an Archimedes spiral groove 13 is arranged on the disc surface of the spiral disc 2, the spiral disc 2 is meshed with the transmission shaft 5 through an internal spline 11 and an external spline 14, so that the spiral disc 2 can transmit the rotary motion of the hand wheel 1 to the transmission shaft 5, and further the transmission shaft 5 drives an output device to move, wherein the output device can be a control surface or an adjustment sheet driven by a steel cable soft transmission system and a control surface or an adjustment sheet driven by a pull rod rocker hard transmission system; the pointer component 3 is composed of a driven hole 15, a rotating hole 16, a rotating pin 17, a driven pin 18 and a pointer 19, wherein one end of the rotating pin 17 is in interference fit with the rotating hole 16, the other end of the rotating pin is in clearance fit with a bush 23 in the support 4, one end of the driven pin 18 is also in interference fit with the driven hole 15, the other end of the driven pin 18 is arranged in an Archimedes spiral groove 13 in the spiral disc 2, when the hand wheel 1 drives the spiral disc 2 to rotate, the driven pin 18 rotates around a fixed point of the rotating pin 17 at a fixed radius under the action of the spiral disc 2, the pointer 19 is further driven to move around the fixed point of the rotating pin 17 along the upper track of the support 4, and the angle scale plate 25 indicates the deflection value of the transmission shaft output device.
Through the above description of the installation and matching manner of the angle measuring and indicating device based on the archimedes spiral disc, and with reference to fig. 9, when the structure of the pointer assembly 3 is determined, the distance R between the rotating pin 17 and the driven pin 18, the distance R between the rotating pin 17 and the terminal of the pointer 19, and the included angle θ between R and R are all constant values, and when the hand wheel 1 drives the spiral disc 2 to rotate for 1 turn, the driven pin 18 moves forward or backward along the circumference with the radius R to move the chord length to be the displacement of one pitch P, and then the pointer 19 moves forward or backward along the circumference with the radius R by n scales. Because the spiral disc 2 can transmit the rotation motion of the hand wheel 1 to the transmission shaft 5, and a specific transmission coefficient i corresponding relation exists between the rotation turns of the transmission shaft 5 and the deflection angle of the output device, the deflection angle of the output device can be linearly and accurately measured and visually displayed through the conversion of the Archimedes spiral disc 2 between the hand wheel 1 and the pointer assembly 3.
If the deflection angle of the output device reaches the upper limit β ° or the lower limit- β ° when the hand wheel is rotated forward or backward m turns, the deflection angle x of the output device and the arc length y of the scale 25 displaying the deflection value should satisfy the following relationship:
as shown in the attached figures 3 and 8, the hand wheel 1 and the support 4 are provided with lightening holes, so that the weight of parts can be reduced under the condition of ensuring the strength, and the lightening of the whole structure device is facilitated.
Referring to fig. 8, the support 4 is fixed on the mounting surface through the positioning hole 24, and the bearing 21 in the bearing hole 20 can support the transmission shaft 5 and isolate the rotation motion of the transmission shaft 5 from the support 4, so that the support 4 is kept in a static state; the two ends of the angle cutting plate 6 are provided with flanges 26 which can prevent the over-range deflection of the pointer 19.
