摘要： The invention relates to an electric machine, in particular a starter device (10) for an internal combustion engine. It comprises a noise-optimized toothing system (232, 234) of two gearwheels (22, 25) which can be brought into engagement with one another. The noise-optimized toothing system (232, 234) is configured as an extra-deep toothing system on at least one of the gearwheels (22, 25), which extra-deep toothing system has an asymmetrical toothing profile (214).

摘要： In the toothing system (1) of a gearwheel having a multiplicity of teeth (2, 3; 19), the tooth flanks (4, 5, 6; 22) of which are of involute configuration above a tooth root region (7, 8, 9; 23) of the tooth flanks (4, 5, 6; 22), the tooth root region (7, 8, 9; 23), as viewed in a normal section and which extends between a root use point (15, 16, 17; 23) and a root point (F), of the tooth flanks (4, 5, 6; 22) is of elliptical configuration, adjoins the involute region of the tooth flank (4, 5, 6; 22) tangentially at the root use point (15, 16, 17; 24) and bears tangentially against the tooth root circle (FKS) at the root point (F). In its tooth root region (7, 8, 9; 23), the tooth flank (4, 5, 6; 22), as viewed in a normal section, follows substantially a part section (B) of an ellipse (10, 11, 12; E) having semiaxes (a, b) of different length, wherein one semiaxis (a, b) of the ellipse (10, 11, 12; E) is inclined at an ellipse tilting angle alpha which is greater than 0° and less than 90° to a radial (R) through the root point (F). Furthermore, the tooth flanks (4, 5, 6; 22) of the teeth (2, 3; 19) of the toothing system are configured symmetrically with respect to one another, in relation to a plane of symmetry (A) which divides the respective tooth (2, 3; 19) in the axial direction.

摘要： Disclosed is a method for producing an at least partly surface-compressed metallic gear element that comprises a compressed sintered material in order to improve a strength curve. A blank of the gear element is produced with a locally selective oversize (701) relative to a final size of the gear element and is rolled by means of at least one rolling tool so as to obtain the final size. The gear element is compressed in a locally varied manner at least in the area of at least one flank (705; 706) and/or one root (704) of a tooth of the gear element in order to create a compressed surface layer.

摘要： A method of determining an optimized face cone element for spiral bevel and hypoid gears. The form of the root fillet of one member of a gear pair is determined and that from is transferred to the tip of the other member of the gear pair. With the inventive method, tooth root-tip clearance is optimized and the contact ratio is maximized while avoiding root-tip interference between mating gear members.
