Abstract: A worm gear mechanism (44) comprises a worm (70) and a worm wheel (80) meshed with the worm. In the teeth of a hob (90) used for the gear cutting of the worm wheel, at least the addendum surfaces (91c) are formed into arcuate shapes. The radial centers (93) of the arcs of the addendum surfaces are positioned nearer to a center line (WL′) of the hob than a pitch line (94) of the hob. The worm wheel is cut into a gear by the hob. The worm is formed into the same shape as the hob. The recess meshing length (L) of the worm gear mechanism is designed to be greater than the recess meshing length (Llim) of a conventional worm gear mechanism.

Abstract: A driven gear includes a radially outwardly extending flange. The radially outwardly extending flange extends along an axial distance defined along a center axis of the flange. The flange merges into a generally conical portion which, in turn, extends radially inwardly to a hub. The hub extends to a remote end. A first distance defined between the remote end of the hub and an end of the flange faces the remote end. A second distance is defined between ends of the flange, with gear teeth formed at an outer periphery. A ratio of the first distance to the second distance is between 2.54 and 2.82. An oil pump, a rotating portion for an electrical generator, and a generator are also disclosed.

Abstract: Bevel gear having a main body comprises a heel-side skin surface. The bevel gear has at least one tooth gap, which exits from the main body in the region of the skin surface. The tooth gap has a tooth base, the profile of which is defined by a base cone angle in relation to the workpiece axis of rotation. A concentric circumferential ring structure is provided on the skin surface, which is raised in relation to the skin surface, and which results in a heel-side exit angle between the tooth base and the ring structure, which is in the range between 125° and 160°.
