Summary
[edit]DescriptionYauza 209-1 (disassembly) - takeup spool 04 - friction pads.jpg |
English: Parts of the takeup spool of the Soviet Yauza 209-1 reel-to-reel tape recorder. . Here is one of the disks with three friction pads. Pretty worn but it works.
The spool of a simple tape recorder is a complex affair. This one has two friction clutches. They (a) prevent jolts of tape tension at the end of the reel (b) stabilize tape tension during playback and recording, which would otherwise vary from the beginning to the end of the reel. This is a so-called weight-sensitive clutch: it adjust tension depending on the weight of the reel of tape.
Русский: Составные части приёмного подкассетника магнитофона Яуза-209-1. В нём живут два фрикционных сцепления. Их задача - гасить рывки ленты в конце перемотки, и стабилизировать натяжение ленты при воспроизведении и записи. Это так называемый весочувствительный подкассетник - сила сцепления завист от веса катушки, т.е. от количества ленты на ней. |
