摘要： A method of manufacturing a gear drive for a seat adjuster assembly may include applying a cutting process to a worm gear blank to cut gear teeth into the worm gear blank and form a single-enveloping worm gear; forming a worm with a helical thread that includes a pitch surface that is configured to mesh with the gear teeth of the single-enveloping worm gear. A longitudinal crown is created on the pitch surface of the helical thread of the worm such that the pitch surface has an arcuate profile moving from a proximal end of the worm to a distal end of the worm. In addition, a crowned tooth profile is created on the helical thread of the worm that extends in an angular direction between a top land and a bottom land of the helical thread. The crowned tooth profile bows outwardly along a convex curve.

摘要： A rotating cutting tool to cut asymmetrical teeth in a gearwheel in which each tooth (21) has an active flank (A) with a convex profile meshing with the profile of a tooth of an opposing gearwheel meshing with the gearwheel and a secondary concave flank (S), provided with teeth (11) on a generally helical path which extends from one side to the other with respect to a median cross-section (M-M) of the tool which is intended to be intersected by the radius Rp of the gearwheel which is at right angles to the axis of rotation of the tool working on the gearwheel to cut its teeth. The helical teeth have a first flank (CA) which is intended to cut the said active flank (A) of the gearwheel teeth and a second flank (CS) intended to cut the secondary flank (S), the pitch (P1) between the first flank (CA) of the helical teeth being constant and the pitch (P2) of the second flank of the teeth being smaller than the pitch (P1).

摘要： The inventive device includes a work supporting portion for supporting a work rotatably about a first axis, a cutter supporting portion for supporting a cutter rotatably about a second axis different from the first axis and a moving portion for moving the cutter along a reference line extending through the first axis. The second axis is slanted relative to a reference plane oriented perpendicular to the first axis and a blade edge of the cutter is caused to come into contact with the work at an offset position offset from the reference line. The work and the cutter are driven in synchronism and the cutter is moved along the reference line.

摘要： A method wherein a cutting or grinding chamfering tool (25) is guided along the face width of a gear (12, 23, 52) through one tooth slot (8) (e.g. from heel to toe) while it contacts the topland corners (10, 1 1) of the respective concave and convex tooth flanks of adjacent teeth (2, 4). The tool moves to an index position, the gear is indexed to the next tooth slot position and the tool moves through the tooth slot (e.g. from the toe to the heel). The cycle is repeated until all topland corners are chamfered.

摘要： A bevel gear set and a method of manufacturing the same are provided. The bevel gear set may include a first bevel gear and a second bevel gear. The first and second bevel gears may be spiral bevel gears or hypoid spiral bevel gears. The first and second bevel gears may each have a gear tooth surface having a plurality of teeth formed thereon, such that the teeth of the first bevel gear and the teeth of the second bevel gear are configured to engage in a meshing engagement. The teeth are machined onto the respective gear tooth surface via a face milling process. Each tooth includes a tooth top, a plurality of meshing surfaces, and at least one chamfer. The chamfer may be formed at an abutment edge disposed between the tooth top and a respective meshing surface via a brushing process directly following the machining of the teeth.
