993,349. Securing elements on shafts. DAIMLER-BENZ A.G. Dec. 3, 1963 [Dec. 6, 1962], No. 47795/63. Heading F2U. In a circumferentially toothed coupling for securing an element, such as a gear-wheel, on a vehicle drive-shaft the tooth gaps of one of the members are arranged to increase in width in the axial direction, those of the other member being parallel, whereby the twist in the member when under maximum torque brings the tooth flanks of the respective members into continuous engagement. As shown, the diverging tooth gaps 13 are provided on the shaft 10, the flanks being formed by a milling cutter 16 whose direction of feed is inclined at an angleαto the longitudinal axis 11 of the shaft. The angles of inclination of adjacent flanks may be equal or unequal, according to whether or not the torque imposed on the shaft in reverse drive is equal to that in the normal direction of drive, Fig. 3 (not shown). |
