摘要： A vibration reduction apparatus for use with a hammer tool having a hammer piston is disclosed. The hammer piston is caused to reciprocate in the cylinder by rotation of a gear wheel and crank drive. A cam is mounted around the gear wheel, a counterweight surrounds the piston cylinder, and a cam follower is provided on the counterweight. The cam follower on the counterweight is urged into contact with the cam by a biasing element. The external profile of the cam is such that rotation of the gear wheel causes oscillation of the counterweight in antiphase to motion of the hammer piston to counteract vibrations produced by operation of the hammer action of the tool. A mechanism is provided to deactivate the vibration reduction apparatus when the hammer action of the tool is deactivated.

摘要： The invention relates to a hand-held power tool for predominantly percussively driven tool attachments, in particular hammer drills and/or a chisel-action hammers. The power tool has a percussion axis and an intermediate shaft that is parallel to the percussion axis and which has a first stroke generating device having a first stroke element for a percussion drive. Additionally, at least one additional second stroke generating device having at least one second stroke element is provided for driving a counter oscillator that is arranged on or about the intermediate shaft and can be driven by the intermediate shaft. A phase displacement that is different from zero and that is unequal to 180° takes place between a movement of the first stroke element and a movement of at least one second stroke element.

摘要： A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.
