Embodiment
Hereinafter, the utility model is described in detail with embodiment referring to the drawings：
As shown in figure 1, a kind of measurement apparatus of the rotating machinery anglec of rotation, including rotating machinery outward flange 1, the outer method
Orchid 1 is coaxially fixed with index dial 2, and the side wall of index dial 2 is continuously evenly equipped with multiple measurement flank of tooth 9 in the same direction, the index dial 2
The outer eddy current sensor 4 being provided with towards the measurement flank of tooth 9, the eddy current sensor 4 pass through signal wire 5 and the phase of data acquisition unit 6
Even.
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.
The diameter of eddy current sensor 4 is less than the half of 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 real-time range of the eddy current sensor 4 and index dial 1 is s, then
S=U/＆
Wherein U is 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.
4 a diameter of 3mm of eddy current sensor, sensitivity 1v/mm, 0.6~6mm of the range of linearity.
The two measurement angles of the flank of tooth 9 are 5 °, then machine anglec of rotation a=n*5+5*s/C (number of teeth that n rotates for index dial 1, s
The distance of index dial 1, the C positions index dial flank of tooth slope parameter related to s are arrived for eddy current sensor 4).
With the Ling Mindu ＆=1V/mm of eddy current sensor 4, output voltage range is 0≤U≤5V, machine anglec of rotation a=
23 °, the present invention is illustrated exemplified by C=5：Index dial 1 is arranged on machine, the distance of adjustment eddy current sensor 4 and index dial 1,
Make displacement transducer output voltage 0V；When machine rotates, when the random device of index dial 1 on machine turns to 23 °, whirlpool
The output voltage U of flow 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)；Will output electricity
