    • In the front head (11) of a machine hammer (10), transversely disposed wedges (18) are adapted to lock the working tool (12) so that the working tool (12) is axially movable by form-restricted cooperation with recesses (16) on the working tool (12). Each wedge (18) is locked in the front head (11) by a key (20), which extends across the wedge (18) into engagement with a transverse bore (21) therein. The key (20) has a releasable locking device including a locking element affixed in the front head (11) and formed by a polyurethane block (24). The block (24) is provided with a through bore (27) and has elastically form-recovering material properties. When, for purposes of locking the key (20), the key (20) is pressed through the bore of the block (24), the block (24) is caused to expand resiliently into an annular groove (22) on the key (20), thereby locking the key (20) in the front head (11) and providing its wedge (18) locking function. In use of two wedges (18), one single key (20) is set to lock both wedges (18) and is locked by one single block (24).

    • In a combination tool bit and tool bit holder or chuck, rotary entrainment members (6, 7) extending over different circular arcs are formed in the tool bit holder for transmitting torque to the tool bit shank (8). Corresponding rotary entrainment grooves (9, 10), also extending over different circular arcs, are formed in the tool bit shank (8). Locking members (4) axially retain the tool bit in the holder. The locking members (4) can be displaced radially into or out of the recesses (11, 12) in the tool bit shank (8). The recesses (11, 12) are laterally closed. Due to the different configurations of the rotary entrainment members (6, 7) and the corresponding grooves (9, 10) it is possible to transmit higher torques while avoiding detrimental cross-sectional weakening of the tool bit shank (8).
    • 在组合工具钻头和工具钻头夹持器或卡盘中,在工具钻头夹持器中形成在不同圆弧上延伸的旋转夹带构件(6,7),用于将扭矩传递到工具钻头柄(8)。 相应的旋转夹带槽(9,10)也在不同的圆弧上延伸,形成在工具钻头柄(8)中。 锁定构件(4)将工具刀具轴向保持在保持器中。 锁定构件(4)可以径向地移入或移出工具钻头柄(8)中的凹部(11,12)。 凹部(11,12)是横向关闭的。 由于旋转夹带构件(6,7)和相应的凹槽(9,10)的不同构造,可以传递更高的扭矩,同时避免工具钻头柄(8)的有害的横截面削弱。

    • A percussion tool usable as part of a single tool impact device or a multi-tool impact device. In each case, the tool is rotatably driven by a high-torque rotary actuator with the tool being longitudinally splined and received within a correspondingly longitudinally splined hollow drive shaft of the actuator. The tool extends fully through the drive shaft to a rearward end thereof at which is positioned a percussion hammer to provide reciprocating endwise impact to the tool. The tool is held within the drive shaft by a splined lock member which can be rotated between a release position with its splines aligned with the drive shaft splines, and a locked position with its splines misaligned with the drive shaft splines. The device is mountable on a mobile vehicle having an articulated arm. The multi-tool impact devices utilizes six such units in side-by-side relation with the drive shafts of each having a gear which drivable interconnects the shafts to maintain them synchronized and couple them together for the transmission of drive force therebetween.
    • 可用作单个工具冲击装置或多工具冲击装置的一部分的打击乐器。 在每种情况下,工具由高扭矩旋转致动器旋转驱动,其中工具纵向花键并容纳在致动器的相应纵向花键的中空驱动轴内。 该工具完全穿过驱动轴延伸到其后端,在该后端定位有冲击锤,以向工具提供往复式的直接冲击。 工具通过花键锁定构件保持在驱动轴内,花键锁定构件可以在具有与驱动轴花键对准的花键的释放位置之间旋转,以及其花键与驱动轴花键不对准的锁定位置。 该装置可安装在具有铰接臂的移动车辆上。 多工具冲击装置使用六个这样的单元并联关系,每个驱动轴具有可驱动的轴互连的齿轮,以使它们保持同步并将它们联接在一起,以便传递其间的驱动力。
