<p>The inventive gear drive id formed by toothed wheels (1, 2) provided with teeth (3, 4) or (5, 6) of toothed rims interacting with single- or multi-flow elements. The working profiles of the interacting teeth comprise poleless, convex at a tooth point and concave at a tooth root arc-shaped sections (8, 10) or (7, 9), which are continuously connectable to each other or to involute sections (11, 12). The interacting toothed rims are embodied in such a way that a phase gap of the face tooth intermating at a discrete intermating angle from a point, where the interaction of the tooth face profiles (5, 6) is over to a point, where the interaction of the face profiles of the next tooth pair starts, for example of the teeth (3 4) of the same toothed rims or the teeth (17, 18) of another toothed rim pair (1'', 2''). Said gear drive is embodied in such a way that the face tooth overlap ratio thereof is less than one, for example when the total overlap ratio is less than one including equal to zero.</p> |
