摘要： A hand-held machine tool includes a tool accept for mounting a chiseling tool on an operating axis. A pneumatic hammer mechanism includes a hammer mobile on an operating axis, an exciter, and a pneumatic chamber sealed by an exciter and the hammer, which couples the movement of the exciter to the hammer. The exciter is driven by a motor and moves back and forth between a frontal dead point distant from the tool and a dead point near the tool. A damper device includes a supercharger and a controlled outlet valve. The controlled outlet valve allows air to flow from the supercharger into the pneumatic chamber when the exciter is in the proximity of the dead point distant from the tool.

摘要： A power tool includes a housing, an electric motor, a speed change mechanism, and a protrusion member. The housing defines therein a mechanism chamber. A lubricant is inserted in an interior of the mechanical chamber. The electric motor is accommodated in the housing. The speed change mechanism is disposed in the mechanism chamber and connected to the motor for shift-transmitting rotation of the motor. The protrusion member protrudes to the mechanism chamber from the housing in a protrusion direction. The protrusion member provides a communication passage that has one opening open at a leading end side of the protrusion member in the protrusion direction and another opening open to an exterior of the mechanical chamber. At least a part of the protrusion member provides the communication passage and is made from a resilient material.

摘要： A driving mechanism for a powered hammer having a motor and a tool holder includes a ram mounted for reciprocation in a guide tube section. The ram has a radially outwardly projecting sealing portion and an outer circumferential surface that defines a helically shaped vent channel running from a front end portion of the circumferential surface to a rear end portion of the circumferential surface and being interrupted by the sealing portion. A piston is driven in reciprocating motion of the motor such that an air cushion is generated in a space between the ram and the piston to cause an impact on the tool bit by movement of the ram towards the tool bit. The space between the ram and the piston is temporarily connected with ambient air through the helical vent channel and a recess in the wall of the guide tube section after causing the impact on the tool bit.

摘要： A vibration reduction apparatus (501) for use with a hammer tool having a hammer piston (520) is shown. The hammer piston (520) is cansed to reciprocate in cylinder (530) by rotation of a gear wheel (523) about axis (524), the hammer piston (520) being mounted to the gear wheel (523) via piston arm (531) and pivot pin (522). Reciprocating motion of the hammer piston causes a flying mass (569) to be driven along cylinder (530) to impart a hammer action to a bit of the tool. The gear wheel (523) is caused to rotate about axis (524) by meshing of gear (514) on drive shaft (511) with gear teeth (532) on the periphery of gear wheel (524), the drive shaft (511) being caused to rotate by a motor (not shown) of the tool. a cam (533) is rigidly mounted around gear wheel (523), a counterweight 5219 surrounds piston cylinder (530), and a cam follower (534) is provided on counterweight 521. The cam follower 534 on counterweight 521 is urged into contact with cam (533) by means of a compression spring (535). The external profile of the cam (533) is such that rotation of gear wheel (534) to cause reciprocating motion of hammer piston (520) causes oscillation of counterweight (521) relative to piston cylinder (530) in antiphase to motion of the hammer piston (520) to counteract vibrations produced by operation of the hammer action of the tool

摘要： A hand machine tool is equipped with a hammer mechanism, which has a hammer (1) that moves axially back and forth in a guide tube (2); a spring mechanism (4) is provided, which exerts a force on the hammer (1) and can set the hammer (1) into a movement toward a tool (3) that can be inserted into the hand machine tool. The hammer mechanism produces a very high individual hammering energy at a relatively low hammering frequency by virtue of the fact that after each impact, the hammer (1) is set into a motion counter to the force of the spring mechanism (4) in order to stress this spring mechanism and after the stressing of the spring mechanism (4), the hammer (1) is abruptly released again so that it flies toward the tool (3).
