    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： It is an object of the present invention to provide an improved technique for preventing leakage of lubricant from an accommodating space that houses a driving mechanism, while regulating the internal pressure of the accommodating space in a power tool. A representative power tool includes a power tool body, a tool bit, a driving mechanism, a lubricant, an accommodating space, a passage and a lubricant leakage preventing region. The accommodating space is disposed in the body to house the driving mechanism and is hermetically sealed. The passage has an accommodating space side opening and an outside opening. The passage extends, starting from the accommodating space side opening, in a direction away from the outside opening. Then, the passage turns around and extends toward the outside opening. Further, the lubricant leakage preventing region is provided with the passage to prevent the lubricant from leaking from the inside to the outside of the accommodating space.According to the invention, the length of the passage can be made longer and the lubricant must travel a longer distance before leaking out. Therefore, a higher effect of preventing leakage can be obtained.

    摘要翻译： 本发明的目的是提供一种用于防止润滑剂从容纳驱动机构的容纳空间泄漏的改进技术，同时调节电动工具中的容纳空间的内部压力。 代表性的电动工具包括动力工具主体，工具钻头，驱动机构，润滑剂，容纳空间，通道和润滑剂泄漏防止区域。 容纳空间设置在主体中以容纳驱动机构并被密封。 通道具有容纳空间侧开口和外部开口。 通道从容纳空间侧开口开始沿远离外部开口的方向延伸。 然后，通道转向并向外侧开口延伸。 此外，润滑剂泄漏防止区域设置有通道，以防止润滑剂从容纳空间的内部泄漏到外部。 根据本发明，可以使通道的长度更长，并且在泄漏之前润滑剂必须行进更长的距离。 因此，可以获得更高的防止泄漏的效果。

    摘要： A rotary hammer and a power tool. The rotary hammer is operable in an idle mode and a hammer mode and comprises a housing and a barrel positioned in the housing and having a forward portion. A ram is positioned within the barrel and is movable relative to the barrel between hammering positions and an idle position. In some aspects, a ram catcher assembly is positioned along the axis adjacent the forward portion of the barrel to releasably hold the ram in the idle position. The ram catcher assembly includes a friction member frictionally engageable with the ram and a damping member at least partially surrounding the friction member. As the ram moves to the idle position with a force, the damping member absorbs at least a portion of the force and the member applies friction to the ram.
