Device coupling arrangement, has drive unit attached on blocking unit and including rotary unit, and pin rotor that is formed on blocking unit and driven by pin, which is formed on rotary unit, to enable axial movement of blocking unit

摘要

The arrangement has a blocking unit (7) in a receiving space of a ring-shaped part, and a drive unit (5) attached on the unit (7). The unit (5) has a rotary unit (5`), which is fitted on the part and rotatable relative to the part. A pin is formed on the unit (5`) to rotate together with the unit (5`). A pin rotor (73) is formed on the unit (7) and driven by the pin to enable an axial movement of the unit (7) between axial positions.
