Abstract
A connection (4) of a first (2) to a second (3) cylindrical component for the transfer of circumferential and axial forces. The first component (2) has locking elements (9a) arranged on its circumference and at the end, the second component (3) has windows (12) associated with the locking elements (9a), and the first and second components (2, 3) can be plugged one into the other at the ends to form a positive interlock between the locking elements (9a) and the windows (12).

A connection of a first cylindrical component to a second cylindrical component for transfer of circumferential and axial forces, the first component (2) having locking elements (9) around its circumference at a front end, the second component (3) having windows (12) associated with the locking elements (9), and the first and the second cylindrical components (2, 3) are plugged with their ends one into the other to produce an interlocking engagement between the locking elements (9) and the windows (12), the locking elements (9) are in the form of tabs (9a, 9c) that project from the first cylindrical component (2), forming a tooth array (9) and resting at their ends against the windows (12, 12a) such that they transfer axial forces in the compression direction, and in the second component (3), in an overlap zone (ü), bracing tabs (13) distributed around the circumference are cut free, windows (10) associated with the bracing tabs (13) are arranged in the first cylindrical component (2), and the bracing tabs (13) are interlocked with the windows (10) in an axial direction.
A coupling which transfers both rotation and axial forces between a first cylindrical component and a second cylindrical component, the coupling comprising:
- an end portion of the first cylindrical component (2) having a plurality of crown teeth (9a) extending axially therefrom and a plurality of windows (10), the first cylindrical component (2) having an inner radius (D2) and an outer radius (D1);
- the second cylindrical component (3) having a first end section with an inner radius (D1) that is substantially equal to the outer radius (D1) of the first cylindrical component (2), a second end section having an inner radius (D2) that is substantially equal to the inner radius (D2) of the first cylindrical component (2) and a beveled section connecting the first and the second end sections of the second cylindrical component (3);
- the second cylindrical component (3) having a plurality of bracing tabs (13) distributed about a circumference of the first end section and a plurality of windows (12) distributed about a circumference of the second cylindrical component (3) that axially extend from the first end section to the second end section of the second cylindrical component (3) such that one side of each of the plurality of windows (12) is located within the first end section of the second cylindrical component (3) and one opposite side of each of the plurality of windows (12) is located within the second end section of the second cylindrical component (3);
- when coupled, the end portion of the first cylindrical component (2) is located within the first end section of the second cylindrical component (3) and the plurality bracing tabs (13) are axially and radially aligned with the plurality of windows (10) of the first cylindrical component (2) such that remote ends of the plurality bracing tabs (13) are axially engagable with the plurality of windows (10) of the first cylindrical component (2) to transfer axial forces between the first cylindrical component (2) and the second cylindrical component (3);
- and
- when coupled, the plurality of crown teeth (9a) abut axial sides and the opposite sides of the plurality of windows (12), which are located within the beveled and the second end sections of the second cylindrical component (3), to transfer radial and axial forces between the first cylindrical component (2) and the second cylindrical component (3).
