<p>On one coupling half, axially-directed carriers (12) engage matching recesses (16) on the other coupling half (10). Circumferentially-acting carrier contours, are formed by straight side flanks (36 ,37). Opposite side flanks of a carrier are mutually-inclined. Sighted along the coupling longitudinal axis (11), the carriers appear trapezoidal. A common adjuster displaces the carriers radially. Carrier (12) flanks and recesses (16) lie in planes parallel to the coupling longitudinal axis (11). They are alternatively inclined to the axis, permitting carrier flanks to grip behind the recess flanks. The common adjuster is incorporated in the first coupling half. A radially-displaced clamping jaw (13) assembly has a common adjuster in the first coupling half. The clamping section (18) of the adjuster slides axially over wedge surfaces, to cause radial movement of the clamping section and clamping jaws. The wedge faces form guidance grooves running along and inclined with respect to the coupling longitudinal axis. Inner ends of the jaws have profiles gripping at the rear, to exert outward pressure, or draw in radially. The clamping section (18) is basically cylindrical, guided in a matching cylindrical guidance recess (17) of the first coupling half. It has a longitudinal threaded spindle (23) drive. The clamping jaws have opposite guide strips (30). These slide in, and are guided by matching radial guide grooves (31) of the first coupling half, which have a cross-shaped section.</p> |
