摘要： The invention relates to a spur gear differential (1), in particular for motor vehicles, comprising a planet carrier (2) for circulating about a differential axis (X), a first output spur gear (3), which is arranged coaxially to the differential axis (X), a second output spur gear (4), which is likewise arranged coaxially to the differential axis (X), and at least one pair (5) of planet gears (6, 7) that mesh with one another, said pair being rotatably arranged in the planet carrier (2), each planet gear (6, 7) meshing with one output spur gear (3, 4). At least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is conically toothed in such a way that, when the planet gears (6, 7) rotate relative to one another, the at least one of the output spur gears (3, 4) and/or of the planet gears (6, 7) is moved into a position in which a blocking effect is brought about. The invention further relates to a corresponding method for producing a spur gear differential (1) of this type.

摘要： A method for producing a gearwheel having an axis of rotation and a tooth system. The teeth have an axial undercut on the tooth flank sides thereof. A blank is provided having a tooth system, wherein the teeth of the tooth system are provided so as to be tilted relative to the axis of rotation such that a forming tool can advance substantially fully into the tooth flank sides of the teeth through an axial linear motion along the axis of rotation. A preliminary form of the at least one axial undercut can be provided on the tooth flank sides. A first axial forming operation is performed in the form of a first axial forging blow via which a preliminary form of the at least one axial undercut is introduced on the tooth flank sides or an already existing preliminary form of an axial undercut is sized for accuracy.

摘要： A coupling arrangement having a rotational axis, about which the coupling arrangement can rotate, having: a first coupling element with an axially-extending flat-side spur toothing system having radially extending first teeth, a second coupling element with an axially-extending flat-side corresponding toothing system which engages axially into the spur toothing system and has radially-extending second teeth, and at least one means for bracing the first coupling element axially with the second coupling element, which coupling elements are fixedly connected fixedly to one another to rotate together about the rotational axis via the toothing systems to transmit torque. The teeth of at least one of the toothing systems have tooth tip lines that are curved convexly in the axial direction away from a tooth root.
