Hammer mechanism i.e. pneumatic hammer mechanism, for e.g. impact hammer, has damping device including damping unit and force transmission unit with force transmission element for transmitting force on damping unit

摘要

The mechanism has a damping device (12a) for damping repulsions and including a damping unit (16a) and a force transmission unit (14a) that transmits force on the damping unit. A holding unit (20c) holds a force transmission element (18a) of the transmission unit in one position in a peripheral direction. The holding unit is radially arranged within the damping unit. A protection unit (24a) is arranged between the damping and force transmission units. The transmission unit includes a stop surface (26a) formed as curved around an axis different from a hammering axis (28a).
