SU96262A1 - Reversible asynchronous slip clutch - Google Patents

Description

Reversible asynchronous couplings based on the use of two oppositely rotating DC electromagnets acting on the measles of the coupling are known.

A feature of the described slip clutch is that the windings of the electromagnets are included in the opposite shoulders of the electronic bridge circuit.

With this switching scheme, both electromagnets are constantly excited and it is possible to adjust the speed of the output shaft and change its direction of rotation as a function of the magnitude and polarity of the voltage applied to the grids of the electron tubes.

The anchor of the coupling is made in the interior of the aluminum cylinder, as a result of which the moment of inertia of the core decreases sharply and the speed of the coupling increases.

FIG. 1 shows an asynchronous coupling device; in fig. 2 is a schematic diagram of a lamp bridge for controlling an asynchronous coupling.

The reverse asynchronous one is made as follows: two electromagnet rotating in opposite directions; 1 mt / armor type (Fig. 1) are located inside the fixed case 2. The rotation of the electromagnets is fixed around the horizontal axis by means of bearings. 3 and rollers 4 and o, representing one purpose. With the corresponding P1, by them magnetomaterial electromagnets.

The current is supplied to the electromagnet coils 6 by means of slip rings 7 and brushes 6.

Electromagnets are driven to Brap1 by an electric motor 9. A JO motor is connected by a coupling // to a shaft of a left electromagnet, on whose magnetic circuit a conical gear 12 is mounted, coupled with intermediate bevel gears 75 rotating around axes 14. gears 3 rotation is transmitted to the bevel gear 75, mounted on the magnetic circuit

right electromagnet, the direction of rotation of which turns out to be opposite to the direction of rotation., enp "left electromagnet.

To the air gap of both itcnjemaOTCH aluminum electromagnet: niy FLOOR qi, 1 Cylinder 16, which is the coupling core. By means of a disk / 7, which is integral with the cylinder Ifi, the rotation is transmitted to the output shaft 18, which is reinforced in the bearings 19. When the electromagnets are turned into a cylindrical one; cortex, eddy currents arise, which, when borrowing;) with rotary | imup1, imis electromagnetic fields, create a total rotational moment equal to the difference between the rotating moments arising from the individual effects on the cylinder from the left and right electromagnet.

With the same excitation current of both electromagnets, the total torque is zero and the cylinder remains in a non-moving state. If the excitation current of one of the electromagnets is greater than the excitation current of the other electromagnet, then the cylindrical measles will rotate in the same direction in which it rotates
