The invention relates to a multistage shaping method comprising a main shaping stage in which the applied pressing power is greater than in the other shaping stages. In order to be able to perform the main shaping stage eccentrically from the pressing carriage and nevertheless produce shaped pieces with parallel faces, the main shaping stage is performed using a lateral extrusion process.
The invention relates to a shaft coupling for non-rotatably coupling two coaxially arranged shaft elements and to a transmission comprising at least one shaft coupling. In order to simplify manufacture, one shaft element is provided with an external toothing containing tooth spaces into which rollers are inserted. Said rollers are radially impinged by a clamping cone when the clamping cone is displaced axially to the external toothing, said clamping cone radially extending over the external toothing and having cone profiles which are complementary to the tapered rollers. Shaft couplings of the above type allow a smaller axial construction space as compared to synchronized claw couplings.
