Disk coupling unit comprises rotatable body, concentric rotatable component and disk coupling comprising disk connected to rotatable body

摘要

Disk coupling unit has a rotatable body (1), a concentric rotatable component (2) and a disk coupling (3) comprising a disk (4) connected to rotatable body or rotatable component. Friction devices (5) enclose disk on both surfaces (6,7). Friction devices are connected to other of rotatable body and rotatable component and are operable between a clamped state wherein disk surfaces and friction devices are in frictional contact with each other. In this frictional contact state, a slipping or firm hold and a free state are created in which the disk surfaces and the friction devices are freely rotatable relatively to each other.
