SU375664A1 - CORNER CONVERTER - CODE - Google Patents

Description

The device relates to systems that convert an analog variation of a non-electric quantity into a code.

Angle-to-code converters are known that contain a code drum mounted on an axis with coding tracks of bits made in the form of alternating teeth and grooves, and reading elements mounted against each coding track and made on a U-shaped magnetic core with windings.

The proposed device is distinguished by the fact that in each bit, except the youngest, the teeth of the coding tracks and the magnetic cores of the reading elements are located at an angle to the axis of the code drum.

This embodiment can improve the reliability of the device.

The drawing shows schematically the Converter angle - code.

It contains an axis / coded drum 2 with low-order coding tracks 3, high-order bits 4, and reading elements 5-8.

The teeth and oases of the coding tracks of the high-order bits, except for the lower-order track, are located at a certain angle C with respect to the axis of the code drum. The magnetic cores of the 6, 7, and 8 high-level reading elements are swung at the same angle, except for the reading element 5 of the younger-coding track. I code the Hj .ee device shown in the drawing in gre code.

Such an arrangement of the reading elements of the older bits and the teeth of the corresponding coding paths removes

reducing the size of the transducer by reducing the widening of the tracks of the higher bits or by maintaining the width of the tracks of the higher bits, and hence the size of the reading elements of the high bits

bits, an increase in the signal-to-noise ratio due to the greater distance between the poles of the U-shaped magnetic cores of the reading elements (for example, the reading element 6 as compared to the element 5). Also not

By changing the dimensions of the reading element 6, it is possible to increase the length of the zero points of the magnetic core of the reading element (for example, the reading element 8 as compared to the reading element 6). This may increase the output power.

As the code drum rotates, the magnetic conductivity between it and the reading of them changes, resulting in the necessary code.

Subject invention

Angle converter is a code containing a code drum fixed on an axis with coding tracks of bits made in the form of alternating teeth and grooves, and reading elements mounted against each coding track and made on a U-shaped magnetic circuit with windings, characterized in that in order to improve the reliability of the device, in it, in each bit, except the youngest, the teeth of the coding tracks - and the magnetic cores of the reading elements are located at an angle to the axis of the CODE drum.
