Abstract (en)
[origin: WO2006094940A1] The invention relates to a torque transmitting device with a driving part (1), particularly provided in the form of a screwdriver whose profile section (2) positively engages in an essentially cylindrical plug-in opening (3) of a driven part (4). The cross-section of the plug-in opening (3) has a number of, in particular, five or six edge sections (5), which are evenly distributed in the peripheral direction, are identical, are concavely rounded, and which, without folds, merge into convexly rounded identical edge sections (6). The convexly rounded edge sections (6) alternate with the concavely rounded edge sections (5) and have a smaller radius of curvature than the latter. The profile section (2) has a number of grooves (7), which each have a rounded bottom, the number of grooves corresponding to the number of the convexly rounded edge sections (5) of the plug-in opening cross-section, and the profile section also has fins (8) extending between the grooves. The apex lines (9) of the fins (8) or the ground lines (10) of the grooves (7) run at an acute angle to the axial direction of the profile section. The invention is characterized in that outwardly pointing sections of the fins (8) extend on a truncated cone lateral surface about the axis (M) of the profile section (2), and these truncated cone lateral surface sections (11) of the fins (8) merge into the rounded bottoms of the grooves (7) while forming a folding line (12).
