Abstract
A pneumatic hammer has a conversion mechanism with a rotatable input member coupled to the motor and adapted to convert a rotational movement of the input member into a reciprocating movement of an output member. The input member is formed as a first carrier which supports a first planet gear. A first sun gear is coaxially arranged with the first carrier, and is rotatingly driven by the drive motor. A first ring gear is movable parallel to the first axis of rotation between a first position and a second position. A second gear is rotatable around a second axis of rotation parallel to the first axis of rotation. The second gear meshingly engages with the first ring gear when the first ring gear is in the second position, and is disengaged from the first ring gear when the first ring gear is in the first position.
