SU26831A1 - Switchboard to torsiometer with readout of its indications by electric signals - Google Patents

Description

It is proposed in the switch to the torus: an iometer, with readings on electrical signals, to use two different plates of the plate with contacts for 1 to break the electrical circuit with the electric signals of the adjustable and fixed on the contact bar.

To absorb oscillation of the plates (it is necessary to use lead prods.

In FIG. 1 depicts a sketch of a hummer with two plates and the mutual position of the contacts during operation: with the device; FIG. 2 is a diagram of the installation of devices and electrical circuits for the tested ales with the indication of the device for axially, along the shaft, the movement of the brushes of the switch and the position of the fixing elements on the contact shaft.

The device is intended to measure and the crossing angles of rotating ales of mechanical installations. The proposed switch device has the effect of making possible a more rapid (instantaneous) closure of the electrical signal circuit. It consists of: a hard metal bracket A (FIG. 1) associated with one of the rear ejectors extending from the current source; The second conductor is a plastine spring C. A circuit closure protrudes through the intermediate laminated frame B, which at its beginning

the free end is in contact with the bracket. Both springs and brackets are mounted on an insulation block J, on which both terminals d and d are also located.

The pin E screwed into the shaft, honed into a wedge, touches the C spring tooth as the shaft rotates and forces it to rise and come into contact with the spring B, drying the circuit for an extremely short time; but at the same instant it lifts the spring S and removes it from contact with the bracket, whereby the circuit is again not closed. Thus, with complete reliability of the circuit closure, the duration of this circuit can be brought to almost infinite brevity, therefore, the accuracy of establishing the position of the contact, so difficult to achieve in this most important place of electrical circuits, can be brought to very high limits.

After the pin has passed, the springs must return to the place without secondary circuit closure, which is achieved by giving the spring B greater inertia and less rigidity compared to (-, the gift of which, on the way back, it is somewhat lagging behind the latter. the danger of re-closure is achieved by using a limiter fitted with lead gaskets (shown in the drawing).

 In the extreme sections of the measuring base of the shaft, two such brushes are installed, one of which is made movable around the circumference with a micrometric measurement of this movement (Fig. 2) and is connected to a common circuit with the telephone to or with a galvanometer (Fig. 2).

In order to obtain moment diagrams for the complete rotation of the shaft, a series of pin-type pins E (Fig. 2 and 1) are screwed into the shaft in its different sections along a helix at both ends of the base. Both contact brushes can be installed 1Y against each pin by axially, along the shaft, moving them with the help of BINT t (Fig. 2).

The subject matter of the invention.
