    • Disclosed is a machine tool having a spindle driven by a drive device, the spindle having a receiving device on its free end for a tool or a tool holder, an input part being provided in the drive train of the drive device, the input part transferring a torque having a defined play in the direction of rotation via drivers to an output part which is joined in a rotationally fixed manner to the spindle, while a torque acting from the spindle in the direction of the drive device and exceeding a torque on the input side is supported on the housing of the machine tool via clamping surfaces on the periphery of the output part, via clamping elements and via a locking ring having a hollow cylindrical surface. The output part is a driving profile having two or more axially parallel planes, of which a first part acts as clamping surfaces and a second part acts as driving surfaces which cooperate with the drivers of the input part.
    • 公开了一种具有由驱动装置驱动的主轴的机床,所述主轴在其自由端具有用于工具或工具夹具的接收装置,输入部件设置在驱动装置的传动系中,输入部件传送 具有通过驱动器的旋转方向上的定义的转矩到以旋转固定的方式连接到主轴的输出部,同时从主轴沿驱动装置的方向作用并且超过输入的扭矩的扭矩 侧通过夹紧元件和经由具有中空圆柱形表面的锁定环通过输出部分的周边上的夹紧表面支撑在机床的壳体上。 输出部分是具有两个或更多个轴向平行平面的驱动轮廓,第一部分用作夹紧表面,第二部分用作与输入部件的驱动器配合的驱动表面。

    • A hand-held power tool having hammer-drilling, drilling and screwing modes, including a mode-setting device having an actuating element, a setting element, and a gear unit for driving an output shaft, in which the actuating and setting elements are interconnected in a rotatably fixed manner, and, in an operating mode(s), the setting element is coupled to a transmission element supported at a coupling housing assigned to the gear unit and axially displaceable at the coupling housing in a screwing position associated with the screwing mode and is axially fixed in position at the coupling housing in hammer-drilling and drilling positions of the corresponding modes; the transmission element is connected to the coupling housing in a rotatably fixed manner, a predefined operating mode being settable by rotating the setting element; the setting and transmission elements being rotatable relative to one another, the setting element embracing at least sections of the transmission element.
    • 一种具有锤钻,钻孔和旋拧模式的手持式电动工具,包括具有致动元件的模式设定装置,设定元件和用于驱动输出轴的齿轮单元,其中致动和设定元件相互连接 以可旋转地固定的方式,并且在操作模式中,设定元件联接到支撑在分配给齿轮单元的联轴器壳体处的传动元件,并且在耦合壳体处可以在与螺钉相关联的螺纹位置中轴向移动 在相应模式的锤钻和钻孔位置轴向固定在联轴器壳体的位置; 传动元件以可旋转地固定的方式连接到联接器壳体,通过旋转设定元件可设定预定义的操作模式; 所述设置和传输元件可相对于彼此旋转,所述设置元件至少包含所述传动元件的一部分。
