    • An impact device includes a housing, a motor supported by the housing, a stationary shaft, and a rotating transmission member supported on the stationary shaft for rotation. The rotating transmission member includes a hub having a first cam surface. The impact device also includes a rotating impact member carried by the transmission member and rotatable relative to the transmission member. The rotating impact member includes a lug protruding from an outer periphery of the rotating impact member and a second cam surface. The impact device further includes a spherical element engaged with the first and second cam surfaces on the hub of the rotating transmission member and the rotating impact member, respectively, an energy-absorbing member exerting a biasing force against the rotating impact member, and a reciprocating impact member oriented substantially normal to the stationary shaft and impacted by the lug of the rotating impact member.
    • 冲击装置包括壳体,由壳体支撑的马达,固定轴和支撑在固定轴上用于旋转的旋转传动构件。 旋转传递构件包括具有第一凸轮表面的轮毂。 冲击装置还包括由传动构件承载并可相对于传动构件旋转的旋转冲击构件。 旋转冲击构件包括从旋转的冲击构件的外周突出的凸耳和第二凸轮表面。 冲击装置还包括与旋转传动构件的轮毂和转动的冲击构件上的第一和第二凸轮表面接合的球形元件,对能够旋转的冲击构件施加偏置力的能量吸收构件, 撞击构件基本上垂直于固定轴定向并且被旋转的冲击构件的凸耳撞击。
