    摘要： A method for producing a toothing on an in particular round workpiece, wherein the teeth are produced by a shaping method using a tool which moves along a path which is controlled by a lifting cam and in the case of which an exchange movement that runs substantially in the radial direction of the workpiece follows a downward movement which runs in the axial direction of the workpiece and serves to produce the tooth flanks, wherein the exchange movement is superimposed with a downward movement such that a curved path is produced during the exchange, is characterized in that the relative rake angle γ
    rel of the tool (200) does not fall below a minimum rake angle γ
    min which corresponds to the rake angle γ of the tool (200), said rake angle γ being reduced by the angle δ between the longitudinal axis of the workpiece and the direction vector of the tool movement.

    摘要： A power screwdriver overload prevention means (100), which is arranged between an input drive part (110) and an output drive part (102, 121) and which interrupts the transmission of torque between the input drive part (110) and the output drive part (102, 121) when a threshold torque is exceeded, is characterized in that the input drive part (110) has at least one ring of balls (130) that is arranged in a rotationally fixed manner in the input drive part, in that the output drive part (102, 121) has at least one ring of balls (140; 141, 142) that is arranged in a rotationally fixed manner in the output drive part (102, 121), and in that the ring of balls (130) that is arranged in the input drive part (110) is spring-preloaded via the ring of balls (140; 141, 142) arranged in the output drive part (102, 121) such that the balls (130) of the input drive part (110) are located in each case between two balls (140; 141, 142) of the output drive part (102, 121) and thus transmit a torque, and such that, when the threshold torque is exceeded, the balls (130) of the input drive part (110) roll over the balls (140; 141, 142) of the output drive part (102, 121) and thus interrupt the transmission of torque.
