SU400373A1 - ELECTROMAGNETIC VIBRATOR - Google Patents

Description

one

The invention relates to devices for oscillation and can be used in the building materials industry, as well as in other branches of the national economy in the production of various products using vibration.

Electromagnetic vibrators are known, comprising a housing in which the core of an alternating current electromagnet, measles on the spring springs and a device for adjusting the gap between the core and the core are mounted.

The purpose of the invention is to increase the durability of the vibrator during vibro-impact mode, co. swan.

The goal is achieved by the fact that the body of the vibrator is made of two parts interconnected by a device for adjusting the gap between the core and the core, made in the form of a ring with thread, interacting from one side with the right thread, cut to one of the body parts, and the other side - with left-hand thread, made on another part of the body.

The drawing schematically shows the proposed vibrator.

The housing of the electromagnetic vibrator is made of two parts 1 and 2, interconnected by a ring 3 with a thread. In one of the parts of the case the core is fixedly mounted - with

coil i), and in the other - movably on spring springs 6 measles 7, made, for example, with a rod 8 attached to a vibrating element 9. In this case, one of the body parts is made with a right thread that interacts with a ring thread, and a friend with a left a thread that interacts with the thread of the ring (the threads are not shown in the drawing).

Vibrator works as follows. A coil 5 supplies an alternating current voltage to the winding (not shown). At the same time, under the influence of an alternating magnetic field arising in the core, the measles 7 begin to oscillate, collectively, through the rod 8 to the vibrating element 9. Rotate the ring 3 to change the gap between the core 4 and the core 7, which allows you to adjust the vibrator to different modes fluctuations. When tuned to the vibro-impact mode of oscillations, the threaded connection of the ring 3 with parts Y and 2 of the body is significantly relieved by the reactive forces arising from the collisions of the core 4 and the core 7, which increases the durability of the device in strand.

Subject invention

Electromagnetic vibrator, comprising a housing in which an alternating current electromagnet core is installed, measles mounted on spring springs and a device

for regulating 1po K 1 of the gap between the core and the core, which is different, in order to increase the durability of the vibrator under the vibro-impact mode of oscillation, the corius of the latter is made of two parts interconnected by a device for adjusting the gap

between the core and the core, made in the form of a threaded ring, interacting on one side with a right-hand thread, made on one of the parts of the body, and on the other hand - with a left-hand thread, made on the other part of the body.
