Specific embodiment
Hereinafter, referring to the drawings and embodiment the present invention is described in detail：
As shown in figure 1, a kind of measurement apparatus of the rotating machinery anglec of rotation, including rotating machinery outward flange 1, the outward flange 1
Coaxial with index dial 2 fixed, the side wall of the index dial 2 is continuously evenly equipped with multiple measurement flank of tooth 9 in the same direction, outside the index dial 2
The eddy current sensor 4 towards the measurement flank of tooth 9 is provided with, the eddy current sensor 4 is connected by holding wire 5 with data acquisition unit 6.
The measurement flank of tooth 9 is included perpendicular to No. I cylindrical measuring surface 7 of index dial 2, and connects No. I measuring surface 7, divides
Cylindrical No. II measuring surface 8 of inclination of scale 2.
Multiple pilot holes 3 are formed in the index dial 2, index dial 2, outward flange 1 are fixed by bolt and nut component.
/ 2nd of the diameter of the eddy current sensor 4 less than the two measurement tooth pitches of the flank of tooth 9.
The height of the measurement flank of tooth 9 is 30mm.
A diameter of 3mm of the eddy current sensor 4.
The displacement signal of measurement is converted into voltage signal by the eddy current sensor 4.
The eddy current sensor 4 is s with the real-time range of index dial 1, then
S=U/ ＆ wherein U are sensor output voltage, and ＆ is transducer sensitivity
Stroke or backhaul state may determine that by the slope of the output voltage of potential vortex sensor 4.
A diameter of 3 mm of eddy current sensor 4, sensitivity 1 v/mm, 0.6 ~ 6mm of the range of linearity.
The two measurement angles of the flank of tooth 9 are 5, then the * s/C of machine anglec of rotation a=n*5+5（N is the number of teeth of the rotation of index dial 1,
S is distance of the eddy current sensor 4 to index dial 1, the C index dial flank of tooth slope parameter related to s）.
With the sensitivity ＆=1V/mm of eddy current sensor 4, output voltage range is 0≤U≤5V, machine anglec of rotation a=
The present invention is illustrated as a example by 23, C=5：Index dial 1 is arranged on machine, the distance of adjustment eddy current sensor 4 and index dial 1 makes
Displacement transducer output voltage 0V；When machine rotates, when the random device of index dial 1 on machine turns to 23, vortex
The output voltage U of sensor 4 is：（1、2、3、4、5、1、2、3、4、5、1、2、3、4、5、1、2、3、4、5、1、2、3）；By output voltage
It is converted into being respectively apart from s（1、2、3、4、5、1、2、3、4、5、1、2、3、4、5、1、2、3、4、5、1、2、3）；By observing s's
Changing Pattern may determine that n=4, then the * 3/5=23 of machine anglec of rotation a=4*5+5.
