Abstract
A rotationally fixed connection of first and second components (2, 4) of a transmission (1) for torque transfer. The fixed connection is produced by the combination of two different types of connection elements (6, 7, 8, 9), such that the connection elements (6, 8) of a first type ensures the mutual centering of the first and the second components (2, 4) to be connected and torque transfer, while the connection elements (7, 9) of a second type enable the first and the second components (2, 4) to be axially fixed and transfer axial operating forces.

A rotationally fixed connection of first and second components (2, 4) of a transmission (1) for torque transfer, the rotationally fixed connection comprising:
- a combination of two different types of connection elements (6, 7, 8, 9) such that the connection elements (6, 8) of a first type ensure mutual centering of the first and the second components (2, 4) to be connected and torque transfer, while the connection elements (7, 9) of a second type enable axial fixing of the first and the second components (2, 4) and transfer of axial operating forces.
A rotationally fixed joint for transferring torque within a transmission (1), the joint comprising:
- a first component (2) comprising a cylindrically shaped wall and a base with a plurality of each of slots (6) and rivet holes (7), the slots (6) and the rivet holes (7) being alternately, uniformly, radially arranged about a circumference of the base of the first component (2);
- a second component (4) comprising a cylindrically shaped wall and a base with a plurality of each of coupling elements (8) and rivet studs (9), the coupling elements (8) and the rivet studs (9) extending from an exterior face of the base of the second component (4) and being alternately, uniformly, radially arranged about a circumference of the base of the second component (4);
- the base of the first component (2) being coaxially aligned with the base of the second component (4) such that an exterior face of the base of the first component (2) abuts the exterior face of the base of the second component (4) and each of the plurality of the slots (6) receives and engages an associated one of the plurality of the coupling elements (8) and each of the plurality of the rivet holes (7) receives and engages an associated one of the plurality of the rivet studs (9);
- and
- engagement between each of the plurality of the slots (6) and the associated one of the plurality of the coupling elements (8) facilitates coaxially alignment of and torque transfer between the first component (2) and the second component (4), and the engagement between each of the plurality of the rivet holes (7) and the associated one of the plurality of the rivet studs (9) facilitates axial coupling of and transfer of axial forces between the first component (2) and the second component (4).
