Description

one

The invention relates to instrumentation, automation and computer technology and can be used in recording equipment and in devices for input and output of information on tape media.

Device for reeling tape carrier is known, which contains a cone connected to the drive mechanism and freely mounted on the shaft, inside which it is mounted for movement (along the shaft by means of a stop screw, an additional cone, with the cavity between the cones filled; viscous liquid,

  In the proposed device for;

On shigi, I izoborzhen scheme 1

the proposed device; on figAZ - view along arrow A on I.

Inside the housing I there is a driven shaft, 2, on which a driving cone 5 is freely located connected with the c-drive mechanism 3 and mounted in the support arms 4. Inside the cone on the shaft 2 is installed with the possibility of movement along the axis

shaft additional cone 6, the shaft and the cone 6 are connected by a key 7. The cavity 8 between the cones 5 and 6 is filled with liquid. A cone is mounted on cone 5;

in the form of balls 9, membranes 10 with the Zebra center and screw II with gear-12. A spring 15 is installed between the shaft 2 and the cone b. The device also contains a gear

a sector 1 pivotally mounted to a post 15 and coupled to a spring 16 and a shaft 17 of the electromagnet 18, the shaft 2 is connected to the cassette 19.

The device works as follows.

) By the way.

The drive mechanism 3 transmits the rotation to the cone 5 and, due to the liquid friction, the driven shaft 2 rotates along with it. To increase the torque during operation of the device on the driven shaft 2, an electromagnet 18 is turned on, which pulls in the shaft 17 and thus turns the sector 14, which in turn, leads to the rotation. the gear 12 of the screw II, as a result of which the screw is screwed in j.

the thread in the bearing C - and thereby raises the ball 9, the membrane 10 and the cone 6, bringing it closer to the cone 5, thereby reducing the working gap between them.

As a result, the torque on the shaft 2 increases, to reduce the torque: the electromagnet 8 is turned off on the shaft, as a result of which the spring 16 returns the sector 14 and the bore 17 to its original position, while the gear JI2 of the screw II lowers the balls 9, the diaphragm 10 and with them a cone 6, thereby increasing the working gap b between the cones,

SUBJECT OF INVENTION

. A device for winding the tape carrier, containing a cone connected to the drive mechanism and freely located on the shaft, inside of which is mounted for movement along the shaft with the help of a stop screw

A 5 conical cone, wherein the cavity between the cones is filled with a viscous fluid, characterized in that with; the purpose of increasing the torque on the shaft, there is a top stern on the screw that interacts with the spring-loaded toothed sector; associated with the electromagnet crust.
