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