Description

The invention relates to electrical engineering and can be used in. technological devices, machine tools and tools.

The aim of the invention is to reduce vibrations.

FIG. 1 shows an electromagnetic actuator of reciprocating motion, a slit; in fig. 2 and 3 - drive box, embodiments.

Electromagnetic actuator reciprocating motion (Fig. 1) contains a cylindrical inductor consisting of a magnetic core 1 and a winding 2, as well as measles, made of two identical parts 3 and 4. Each part of the core contains a ferromagnetic element 5 and is fixed on its end face, - inside the inductor, the electrically conductive element 6. The distances from the geometric centers 7 and 8 of the ferromagnetic elements 3 and 5 to the transverse plane of symmetry are the same. The return spring 9 is placed in the axial channel 10 box. For simplicity, FIG. 1 does not show a sliding bearing in which the movement of parts 3 and 5 of the box occurs. It is a thin non-magnetic non-magnetic sleeve placed between the core and the inductor and rigidly attached to it.

The anchor (Fig. 2) contains two parts 3 and 4, each of which contains a ferromagnetic element 5 and an electrically conductive element 6. The axial channel 10 is formed by non-through grooves in parts 3 and 4 of the core, i-well also spring 9.

In the second design of the core (Fig. 3), parts 3 and 4 have a more complex shape.

Electromagnetic actuator reciprocating motion works as follows.

When a voltage pulse is applied to the winding 2 of the drive (Fig. 1), the pulsed magnetic flux (F), the passage through the magnetic conductor of the inductor 1 and the ferromagnetic elements 5 core, is closed through the working air gaps. Electrically conductive elements 6 located at the ends of ferromagnetic elements 5 prevent dispersion

magnetic flux and concentrate it in the working gap. The forces resulting from the presence of magnetic flux in the working gaps are equal in. magnitude and opposite in direction. Under the action of these efforts, accelerated movement of parts 3 and 4 of the core begins in different directions. Thus, during the working stroke of the core, when synchronous engagement of its parts 3 and 4 into the inductor occurs, the latter remains unloaded from mechanical effects. During the working stroke of the core, the external force (load of the drive) and the force developed by the return spring 9, compressed during the working stroke, are overcome by the electromagnetic force. After the end of the current pulse, parts 3 and 4 of the core return to their initial position under the action of the spring 9, and the inductor 1 of the engine is also unloaded from the mechanical action.
