Specific embodiment
Referring to Fig. 1~Fig. 8, angle measurement that should be based on Archimedian screw disk and instruction device by handwheel 1, helical disk 2,
Mechanical 6 composition of indicating hand component 3, bearing 4, transmission shaft 5, angle.During installation, the groove 9 on handwheel 1 and the flange on helical disk 2
12 is close chimeric, therefore the rotation of handwheel 1 can drive helical disk 2 to rotate；2 disk of helical disk is equipped with archimedean spiral groove 13,
Helical disk 2 is meshed with transmission shaft 5 by internal spline 11 and external splines 14, therefore helical disk 2 can pass the rotary motion of handwheel 1
Transmission shaft 5 is handed to, and then output device is driven to move by transmission shaft 5, wherein output device can be cable wire flexible transmission system
The rudder face or trimmer that the rigid transmission system of rudder face or trimmer, pull rod rocking arm of drive drives；Indicating hand component 3 is by driven hole
15th, rotation hole 16, rotational pin 17, follower pin 18 and pointer 19 form, and wherein one end of rotational pin 17 is matched with 16 interference of rotation hole
It closes, the other end and 23 clearance fit of bushing in bearing 4, and one end of follower pin 18 is also interference fit with driven hole 15,
The other end of follower pin 18 is then placed in the archimedean spiral groove 13 in helical disk 2, when handwheel 1 drives helical disk 2 to rotate,
Follower pin 18 is rotated under the action of helical disk 2 around the fixed point of rotational pin 17 with fixed radius, so drive pointer 19 around
The fixed point of rotational pin 17 is moved along the top trace of bearing 4, and angle index plate 25 indicates the inclined of transmission shaft output device
Angle value.
Retouching for fit system is installed by the above-mentioned angle measurement for this based on Archimedian screw disk and instruction device
It states, and with reference to attached drawing 9, when the structure determination of indicating hand component 3, distance r of the rotational pin 17 away from follower pin 18, rotational pin 17 are away from finger
Angle theta three between the distance R of 19 terminal of needle and r and R is constant value, when handwheel 1 drives 1 circle of rotation of helical disk 2, follower pin
18 be r along radius circumference be moved forward or rearward the displacement that chord length is a pitch P, and then pointer 19 is along the circle that radius is R
Forwards, backwards or move backward n scale in week.Because the rotary motion of handwheel 1 can be transferred to transmission shaft 5 by helical disk 2, and is driven
There are the correspondences of a specific gearing factor i, therefore, output between the turnning circle of axis 5 and the drift angle of its output device
The deflection angle of device is able to linear accurately measurement by the conversion of Archimedian screw disk 2 between handwheel 1 and indicating hand component 3
And it intuitively shows.
If handwheel rotates m circles forward or backward, the deflection angle of the output device reach β ° of limes superiors or limit inferior-
β °, then output device deflection angle x and the arc length y of the scale plate 25 of display drift angle value should meet following relationship：
Such as attached drawing 3,8, lightening hole is equipped on handwheel 1 and bearing 4, part weight can be reduced in the case of proof strength
Amount is conducive to the loss of weight of total device.
Such as attached drawing 8, bearing 4 is fixed on by location hole 24 on mounting surface, and the sustainable biography of the bearing 21 in bearing hole 20
Moving axis 5, and the rotary motion of transmission shaft 5 is isolated with bearing 4, make 4 remains stationary state of bearing；Mechanical 6 both ends of angle are equipped with
Rib 26, can prevent pointer 19 outranges deflection.
