SU621017A1 - Tape-driving mechanism driving unit - Google Patents

Description

The invention relates to the accumulation of information, namely, to the leading components of the penetration mechanisms.

Izvesgen is a leading uzep pentoprog mechanism containing a leading vag, which is assembled with the possibility of linking with a magnetic penta and fixed in a flywheel, kinematically connected with an epegrotwighepheme. The known driving unit unit converts the rotation of the driving motor into the translational movement of the magnetic pen.

However, this uzep consumes a lot of energy.

The closest in technical technology to the present invention is the drive unit of the tape mechanism, which contains the drive shaft mounted with magnetic penta mating and reinforced with 6 flywheels mated through the spacing element with the narrowed end of the concentrator of oscillations, the spreading end of which is connected with piezoceramic vibrator r2j. This lead is expensive.

There is little energy moving the tape.

The disadvantage of such a master is that the size of the movement of the magnetic tape is very uneven.

The purpose of the invention is to reduce the irregularity of movement of the magnetic pen

For this, in the proposed device, the tapered end of the concentrator of longitudinal vibrations is made in the form of a bent plug with grooves in which an intermediate element is placed, which is made in the form of a s-shaft with a roller.

FIG. Figure 1 shows one of the possible variants of the proposed master unit of the tape-drawing mechanism; | ig.2 intermediate element.

The drive unit contains a drive shaft 1 mounted with the possibility of mating with magnetic Nenta 2 by means of a pressure roller 3. The driving fork is rigidly fixed in the flywheel 4, conjugated through an intermediate element with a narrowed end of the concentrator of 5 swirled oscillations. Tapered end | On the center, a mountain of longitudinal cohesion is formed in the form of an Eagnugi vipka with grooves 6, in which an intermediate edente is placed, embedded in the form of a stepped vap 7 with a roller 3.

The hub 5 is mounted on the lever 9 mounted on the shaft 10 and spring-loaded by means of the spring 11. The extended end of the hub is connected by a lining 12 to a piezoceramic vibrator 13 made in the form of a BI of the piezoceramic disks connected to the alternating voltage source (on the drawing is not shown).

The oscillations of the piezoceramic vibrator 13 are amplified by the concentrator 5 of longitudinal vibrations. In this case, the tapered end of the concentrator 5 oscillates in elliptical trajectories, which is caused to rotate the stepped shaft 7 of the roller 8, which provides rotation of the flywheel 4. The rotation of the flywheel is transmitted to the drive shaft 1, which leads the magnetic tape 2 to the state of progressive mixing.

The use of the invention will reduce the uneven movement of the magnetic tape and provides a small

burial of energy. The invention can most commonly be used in tape-making machines of magnetic recording apparatus.
