Диски 6 и стаканы скреплены стяжным элементом 3 с гайкой 4 и шайбой 5.The core 2 and the base 1 are made in the form of glasses of different diameters. A 7 _g magnetic tape is placed between the walls of the cups and piezoceramic elements 6 are installed between the bottom parts. A central hole and radial trapezoidal windows are made in the bottom parts of the cups 8. The disks 6 and the cups are fastened with a clamping element 3 with a nut 4 and a washer 5.

Держатель работает следующим образом.The holder works as follows.

При подаче напряжения на дисковые пьезокерамическне элементы 6 в последних возникают механические колебания, которые в виде изгибно-продольных колебаний передаются основанию 1 и сердечнику 2. Колебания основания 1 и сердечника 2 способствуют уменьшению межвиткового трения в рулоне магнитной ленты 7. Оптимальный режим колебаний обеспечивается выполнением и конфигурацией окон 8.When voltage is applied to the piezoelectric disk elements 6, mechanical vibrations occur in the latter, which are transmitted in the form of longitudinal-bending vibrations to the base 1 and core 2. The oscillations of the base 1 and core 2 reduce the inter-turn friction in the roll of magnetic tape 7. The optimal vibration mode is ensured by windows configuration 8.

Изобретение позволяет уменьшить потери энергии на трение и упростить устройство.EFFECT: invention reduces friction energy losses and simplifies the device.
