Description

Basically auth. St. jYo 834/3 described inductive sensor with ribbed cortex and ribbed pole detectors i and electromag. com.

The specified sensor does not decontaminate but the force drinker: scales measuring the arc movements of the Siach:: Telio11 width.

In the proposed construction of the sensor, the elimination of the marked lack of improvement of the core as a part of a helical gear with internal marking is achieved. which allows him, when the nerve; e; tsi1ii along the axis of the new CTO.ia, to change the magnitude | H1U of the gap. and thereby determine the small angles of nepc AieiJieiiHii in the planted areas 1-2.

As a nonius of exact angular displacements, a bridge circuit with two inductive sensors is used, which .- o Keiit, i on the cores with external superstructures, dia: 1 wave 1 G; s,: 11 in the three teeth.

Between the teeth of the pole extensions and the teeth of the core nNieeTcsi there is an air gap of 1.

FIG. I shows G1riptsppial 1a datapka scheme: on fng-. 2 is a diagram of its installation on a machine, and FIG. 3rd electric circuit.

The anchor / sensor is made in the form of exactly 1 bar of the gear wheel and communicates with the object (Paprime), with a rotary stand 2 metal-1 machine, the arc displacement of which is required to be measured. The anchor has 180 or 360 teeth, due to the fact that its anchor will fit the turn of the table 2 –1 or 2 degrees.

The gearbox 1 is associated with a corrective wheel 3, which corrects the gears on the helical gear helical gear box. The counting of degrees is carried out on a scale, using a pan-despp device on table 2. Nonius scale: the tadus is alternated by the arm of the sprung wheel 3.

Cores with on; 1 axle extensions are equipped with windings LI and bi (Fig. 2.)

The windings L, b2 of capacitance Ci and C (Fig. 3) form an alternating current bridge with solid conductors B, amounting to ui-1, they are phase sensitizers; When the core passes through the equilibrium position of the bridge, the indicator U, attached to the output diagonal of the bridge, fixes the phase change.

The zero reading of the device corresponds to the required position of the turning system.

To set the fractions of a degree (miiout and seconds), the pole extensions 4 and 5 are not moved along the table's axis with a short micrometer screw 6. Since measles / vypolie in the form of a helical gear, then when moving pole sets 4 and 5 along the axis of the table, the balance is equal to 1 . and the measles - polestating system of the padstazz is changing. A gigb / three one aiara cor corrected1) is indicated by a ruler (not shown in the drawing), linked to the vernier of the sensor.

Claims (2)

1. Inductive sensor with ribbed shell and ribbed and molded extensions of electromagnets according to ed. St. No. 83473, which is also distinguished by the fact that, in order to obtain a continuous, significant width of measurements of arc displacements, the sensor measles is made in the form of a helical gear and an inductive sensor with pole extensions, performed} F in the form of an internal helical gear. 2. The form of polypropylene according to claim 1, that is, that the sensor with pole extensions alternates the perpendicular of the plane of the turntable by means of a micrometer screw, which makes it possible to fix the exact coordinate of the rotating system.
