Description

This invention relates to boring, in particular, to mechanisms for moving a vaginal carrier in magnetic recording equipment.

Mechanisms are known for moving a magnetic carrier, made on the basis of differential elements, including solar wheels and a carrier. But when using known mechanisms under the conditions of the occurrence of vibration disturbances, the reliability of their operation is not high enough. In addition, the range of speeds used is also not large enough, and to increase it, the mechanism itself becomes complicated.

The purpose of the invention is to increase the reliability of the device intended for transporting a magnetic carrier under conditions of vibration disturbances, and expanding the range of

speeds of movement of the carrier

To do this, in the proposed device, the lower rigidly fixed pulley of the intermediate shaft is connected via a belt to an output shaft that interacts through the overtaking pulley with the driven pulley, and the upper drive shaft is connected to a carrier of the dual differential, one solar wheel of which is rigidly mounted on the device body and the other is connected to the output shaft through its clutch.

The drawing shows the kinematic scheme of the proposed device for transporting magnetic media.

The electric motor 1 is connected via a belt 2 to an intermittent shaft 3, on which pulleys 4 and 5 are rigidly mounted. Pulley 4 is connected through belt 6 to a pulley 7 freely mounted on the output shaft 8. On the same shaft, a solar wheel 9 is freely mounted and led 10, the elements of the differential mechanism. The second solar wheel And is also included in the differential mechanism, Passik 12 serves to communicate the carrier 10 with the pulley 5 of the shaft 3. On the carrier there are satellites 13 and 14 rigidly interconnected and freely rotating rollers

15, 16, the Sun wheel II satat 13 and the roller 15 are covered by the spigot 17, and the 9g wheel the satellite 14 and the rooshk 16 by the spigot 18 The device has used overhangs 19 and 20, made in this case in the form of helical springs, intended for implementation of the kinematic connection between the pulley 7, the sun wheel 9 and the output shaft 8.

When electric motor I mounted on body 21 of the device is switched on, the drive shaft 22 of the electric motor begins to rotate, thereby transmitting the movement of the passive 2 and through it to the intermediate shaft 3. From the latter, by using Passikov 6 and 12, it is rotated. the moment is transmitted simultaneously to pin 7 and the carrier 10. Finally, with the help of the pulley 7, the output shaft 8 is rotated, and with the help of the carrier 10 due to the running in of the satellite 13 relative to the fixed sun wheel 11 via the satellite 14 rotates relative to the shaft in the opposite direction. As a result, the clutch 20 is rotated, and the wheel 9 is disconnected from the shaft 8, whose rotational speed is determined by the parameters of the kinematic chain consisting of an electric motor, an intermediate shaft, pulleys

When the direction of rotation of the shaft 22 of the electric motor 1 19 is reversed and the pulley 7 is disconnected from the shaft 8, and the rotation is transmitted to the four-differential mechanism, the desired speed can be selected based on the use of one or another diameter of the sun wheels 9 and dl: the smaller the difference in their diameters, the lower the speed of the shaft .8. „„.

Thus, it turns out: it is possible to get the required® speed of rotation of the output aal not by using gears, but only by using solar wheels of the appropriate diameter,
