Abstract

The solution describes the construction of a double-acting axial sheath proportional electromagnet, the rectilinear movement of the core of which was taken outside the electromagnet and transformed into a rotary movement. The essence of the solution of this double-acting electromagnet consists in the application of proportional electromagnets, which have a common core, the movement of which is externalized between the electromagnets on the shaft. With this arrangement, a suitable characteristic of the moment on the output shaft was obtained from the angle of rotation of the shaft from. zero position on both sides. The application of a double-acting electromagnet is possible wherever an electromechanical converter is needed to control the angle of the control member of the aggregate.

Description

240512

BACKGROUND OF THE INVENTION The present invention relates to a double-acting jacket electromagnet with an axially movable cylindrical core, the input parameter of which is an electrical signal which is converted by a magnetic circuit into an axial axle which is transformed to change the position angle of the output shaft, wherein the e-electromagnet is Designed for controllers, where the input parameter of the control is to change the angle from zero to one or to the side.

The axial jacket electromagnet is one of the basic electrotechnical elements that is used in practice as an electric-mechanical converter. The single-acting e-electromagnet consists of a coil housing, a fixed pole-face, a movable pole — a core, and a member by which the drive is transferred to another functional member. The design of the various axial sheathed electromagnets is known from the technical literature and these times are similar to those of the electromagnets.

Double acting electromagnets are composed of at least two single acting electromagnets and also have some common features. one of these common features is that they must contain at least two magnetic circuits which, by their effects, act in the opposite sense to each other. The double-acting electromagnet of the stage US 1 498S92, (DT 25 02 714 A1) and US 3 970 981 consists of two separate elements, two fixed poles, one common core and a rod, which transfers the movement of the core outside the magnet body. The core coils to the side of the coil that is electrically retracted or to the side where the value of the electrical signal is greater.

The double acting solenoid of U.S. Pat. No. 4,097,883 has basic portions similar to those of the above-mentioned patents, but differs in design. The motion of the core is led out of the magnet space by the rod.

The aim of the invention is to construct a double-acting and electromagnetic proportional electromagnet, which consists of two mutually opposing co-proportional electromagnets having a common core. between the electro magnets, the rotational movement of the shaft. The transformation of the rectilinear motion into a rotating shaft is effected by means of a pin placed in the core and a lever which is inserted in one end in the pin and a second cone of the shaft. The resulting effect is a change in angle and torque as a function of changing the control electric signal.

The change of angle and torque extends from the zero-clockwise direction to the maximum angle value, limited by the mechanical stop. The course of the twisting moment, depending on the angle change, is either non-declining, invariant, or increasing.

FIG. 1 shows a structural view of a double-acting axial proportional electromagnetic method of the present invention; FIG. 2 illustrates a cross-section through the center of an electromagnet in the locus where the motion effect of the core of the electromagnet is exerted; the shaft is the nature of its possible changes in the constant excitation current I in the solenoid coil.

The properties and effects described in this design can be achieved by constructing the electromagnet of the stage of FIG.

The double acting axial proportional electromagnet consists of two separate jacket electromagnets combined in one unit. The magnetic circuit of one electromagnet is composed of a jacket 3 with which a non-movable pole 2 (2 ‘) is fixed and the movable pole 1 - the core is one piece and is common to the left and right magnetic circuits. Said portions of the magnetically soft conductive material. The movable pole 1 is spaced apart from the face by the thickness of the washer 10 (10 ') of non-magnetic material, the task of which is to reduce the sticky effect between the stationary pole 2 (2') and the movable field 1. the face is a magnetic circuit interrupted by a ring 5 (5 *) of a magnetic non-conductive material. Position 2 (2 ‘), S (5‘), 6 (6 ‘) forms a skeleton for the coil winding 4 (4‘) of the electromagnet, with no ring 6 (6 ‘) being abraded from a magnetically free material.

Since the materials of parts 2 (2 ‘), 5 (5‘), 6 (6 ‘) are electrically conductive, the insulating layer 12 (12‘) is under the winding 4 (4 ‘). The movable pole 1, which is circular in cross section and is shaped at both ends, acts axially. In the middle position, the movable pole 1 is centered by springs 14 (14 ‘). Two mutually oblique holes are guided through the center of the movable pole 1. In one of these, the pin 7 is pivoted into which the end of the pin 8 is slidable. The other end is fixedly connected to the shaft 9, which is supported in bearings 13 (13 ') · Cap 7, pin 8 and hria-def 9 serve to transform the linear movement of the movable pole 1 into a rotational change of the shaft position S. In the case that a stream IB (Ia) is fed into the coil, it causes the movable pole 1 to start to penetrate. to the stationary pole 2 (2 '), the pivot pin 7 is pivoted and together with it the pin 8, which at the same time extends from the pin 7. The tilt of the movable pole 1 by pin 7, pin 8 is transmitted to the shaft 9 begins to rotate in the direction of φΒ, φΑ. If φΒ, φΑ must be a spring
