    摘要： A percussion device that includes: —an input side; —an output side; —at least one drive transmitter; —a drive transmitter pathway; —a percussion impactor; and —a percussion anvil; where: the drive transmitter pathway is a circumferential pathway around a longitudinal axis of the percussion device; —the drive transmitter pathway includes at least one tooth section including a lift section and a lead section; —the at least one tooth section is essentially one wavelength of a sawtooth wave; —the lift section is inclined away from a base of the drive transmitter pathway; —the lead section is a section of the tooth section which abruptly returns to the base of the drive transmitter pathway; —the input side is rotationally isolated from the percussion impactor; —the percussion anvil is attached to, or forms part of, the output side; —the percussion impactor includes an impact end and a force input end which are longitudinally opposite terminal ends of the percussion impactor; and —the impact end faces the percussion anvil; such that: when in use, and the output section is free to rotate, the at least one drive transmitter and the drive transmitter pathway are configured to act co¬ operatively to transfer the rotational motion of the input side to the output side; and —when in use and limited or no rotation of the output side is possible, the at least one drive transmitter and the drive transmitter pathway are configured to act co-operatively to increase, maintain or decrease the distance between the percussion impactor and the percussion anvil; wherein the at least one drive transmitter and the drive transmitter pathway are configured to act co-operatively to accept rotational motion from the input side and transmit a percussive and/or rotational motion to the output side.

    摘要： An electropneumatic hammer of the type in which a driving piston is caused to undergo a reciprocating movement of translation under the action of an electric motor and a striking piston is driven by the driving piston, with the striking piston and the driving piston being mounted in a sleeve, the striking piston being disposed in such a manner as to impart a strike to a tool mounted in a tool-holder spindle, the driving piston being adapted to transmit, in the course of its reciprocating movements of translation, an alternating movement of rotation to the sleeve, the sleeve being connected to rotate with the tool through unidirectional connecting means, and means for imparting to the driving piston, in the course of its reciprocating movements of translation, an alternating movement of rotation about an axis parallel to its direction of translation.
