    摘要： A non-circular sprocket component comprises a rotor (11) having a plurality of teeth (16) arranged around the perimeter of the rotor, each tooth having a crown (9), and each pair of adjacent teeth having a valley (8) therebetween. The crowns of the teeth lie on a curved envelope forming the perimeter of the rotor. The perimeter has a non-circular profile having at least two protruding portions (22, 23) alternating with receding portions (24, 25). The distance between the midpoints (V) of the crowns (9) of each pair of adjacent teeth is substantially the same. The profile of the valley (8) between each pair of adjacent teeth is substantially the same. The distance between the midpoint (V) , of each crown (9) and the axis (A) of the rotor varies around the perimeter to produce the said non-circular profile.

    摘要： The inventive gear drive is 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 form 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.

    摘要： A forged gear and a method of manufacture thereof. The forged gear comprises a bevel gear with a plurality of teeth, each tooth having a tip disposed between two faces and two ends, the two faces extending in a substantially longitudinal direction of the tooth, wherein the tip of each tooth has at least one substantially crowned portion between the two ends along the longitudinal direction. The method of manufacture comprises forging the gear from a blank such that during the forging operation a substantial portion of the length of each forged tooth tip does not contact the die cavity.

    摘要： A gear system which includes a pinion and mating-gear forming a gear pair with predetermined gear ratio (mG), center distance (C), face-width (FW), and limiting stresses. The pinion has a pinion tooth number (N1)nd a first plurality of teeth, each tooth having a first-tooth profile. The mating gear has a mating-gear tooth number (N2) satisfying the expression N2 = mG . N1 and a second plurality of teeth, each tooth having a second-tooth profile. The relative curvature of the first-tooth profile and the second-tooth profile is given by an expression kc . Fc, where Fc is a relative reference curvature function given by the expression Fc= (N1+ N2)2 /(N1. N2 . C), and kc is a relative curvature multiplier which is a function of the gear ratio (mG), the center distance (C), the face-width (FW), and the limiting stresses.
