摘要： A hollow rotor shaft for an electric machine rotor rotating about a longitudinal axis includes: a cylinder shell surrounding a shaft cavity; and end flanges on both shell ends transitioning into respective shaft journals. One end flange has an inlet for leading a cooling medium into the cavity and onto the shell inner surface. Inside the cavity, guides distribute cooling medium entering via the inlet over the inner surface, the shell having at least one cooling-medium outlet opening. The shaft is formed in one piece from a tubular initial body. The guides are raised contours formed from the inner surface and protruding into the cavity. The shaft is flow formed by pressing the raised contour out of the inner surface. The end flanges with respective shaft journals are formed by pressing the two initial body ends. The at least one cooling-medium outlet opening is formed in the raised contour.

摘要： An apparatus for transfer of a torque from an internal combustion engine to an auxiliary unit has an auxiliary unit shaft and a pulley rotatably disposed on the auxiliary unit housing. The pulley and the auxiliary unit shaft are connected with one another by an overload protection device configured to interrupt the connection between the pulley and the auxiliary unit shaft if a predetermined torque is exceeded. The overload protection device has a spring washer having multiple spring arms connected, on the end side, with connection elements of a disk-shaped driver until the predetermined torque is reached. Each connection element is configured as a pocket-shaped mounting in the driver, wherein the respective spring arm end lies against a contact surface of the pocket-shaped mounting under spring tension, with force fit. The respective pocket-shaped mounting is configured as a hook-shaped crosspiece cut out of the driver in certain regions.

摘要： The invention relates to a device for transmitting a torque from an internal combustion engine to an auxiliary unit, in particular to a compressor of an air conditioning system of a motor vehicle, comprising an auxiliary unit shaft and a belt pulley that is arranged on the auxiliary unit housing in such a way that the belt pulley can rotate, wherein the belt pulley and the auxiliary unit shaft are connected to each other by means of an overload safety mechanism, wherein the overload safety mechanism is designed in such a way that the connection between the belt pulley and the auxiliary unit shaft is interrupted when a specified torque is exceeded, wherein the overload safety mechanism has a spring disk having a plurality of spring arms, which are connected at ends thereof to connecting elements of a disk-shaped driver for conjoint rotation until the specified torque is reached. The problem addressed by the invention is the improvement of said device in such a way that the construction of said device is significantly simplified, the design of the response behavior of the overload safety mechanism is improved, and loads in the direction of the axis of rotation are avoided. This problem is solved in that each connecting element of the driver (7) is designed as a pocket-shaped receptacle (11) in the driver (7), wherein the end (10a) of the particular spring arm (10) lies against a contact surface (12) of the pocket-shaped receptacle (11) in a force-locked manner under spring stress, wherein each pocket-shaped receptacle (11) is designed as a hook-shaped web (13) that is cut out from the driver (7) in some regions.

摘要： The intention is to substantially simplify and improve a method for producing a rotary vibration damper (10) having a hub part (6), which can be connected in a rotationally fixed manner to a shaft, and a flywheel rim part (8), which is connected to the hub part (6) by means of an elastomer layer (12), wherein the elastomer layer (12) is arranged in a gap between the flywheel rim part (8) and a region (5) of the hub part (6) that is coaxial to the flywheel rim part (8), the hub part (6) and the flywheel rim part (8) are initially produced in the form of a single-piece workpiece and then the hub part (6) and the flywheel rim part (8) are mechanically separated from each other. This is achieved in that, to form the single-piece workpiece (2), first a blank plate (1) is formed into a well shape in such a manner that the single-piece workpiece (2) has adjacent to the well bottom (3) the coaxial region (5) of the hub part (6), adjacent thereto a radially extended annular or conical web region (7) and adjacent thereto the flywheel rim part (8), wherein the single-piece workpiece (2) is then divided into the hub part (6) and the flywheel part (8) by separation of the annular web region (7) in the axial direction.

摘要： Ein rotationssymmetrisches Bauteil (2) aus einer scheibenförmigen Vorform (1), welches über seiner radialen Erstreckung wenigstens drei Umfangsbereiche mit unterschiedlichen Wanddicken aufweist, wobei die Umfangsbereiche aus der scheibenförmigen Vorform (1) durch ein Umformwerkzeug, vorzugsweise wenigstens eine Drückrolle (6), hergestellt sind, soll so verbessert werden, dass es durch spanlose Umformung auf einfache Weise an unterschiedliche mechanische Anforderungen angepasst werden kann.
Dies wird dadurch erreicht, dass es Umfangsbereiche mit gegenüber der Ausgangswanddicke (t) der Vorform (1) größerer (t 1 ,t 4 ,t 5 ,t 7 ,t 9 ,t 11 ,t 13 ,t 14 ) und kleinerer (t 3 ,t 6 ,t 8 ,t 10 ,t 12 ,t 15 ) Wanddicke aufweist, wobei die Wanddicken der Umfangsbereiche an die mechanischen Beanspruchungen des Bauteils in den jeweiligen Umfangsbereichen angepasst sind.
