ROTARY COUPLING

Abstract:

The invention relates to a device comprising a first component (11) and a second component (12). The first component (11) comprises a cylindrical outer surface (13), and the second component (12) comprises a cylindrical inner surface (17) which is arranged on the outer surface (13) coaxially with a longitudinal central axis (m). First connection surfaces of the first component interact with second connection surfaces of the second component in order to prevent a relative rotational movement of the components (11, 12). The invention is characterized in that one of the connection surfaces forms a retaining toothing (22), and the other connection surface forms mutually spaced longitudinal protrusions (18) which are distributed over the circumference and the tooth flanks of which extend parallel to the longitudinal central axis (m).
