摘要： The invention relates to a method for machining the tip circle diameter of a tooth system (4) of a gearwheel (6), in which the gearwheel (6) rotates about a workpiece axis of rotation (Rw), and in which at least one tooth (9) of the tooth system (4) is machined, by removing chips, by means of a tool (7, 7′) that rotates about a tool axis of rotation (Rz) oriented at an axial distance (A′, A″) relative to the workpiece axis of rotation (Rw). According to the invention, the tool (7, 7′) is disk-shaped, the disk-shaped tool (7, 7′) machines the tip surface (8) of the tooth (9), by removing chips, with at least one partial segment (10a) of its circumferential edge configured as a defined blade (10), wherein a relative movement between the tool (7, 7′) and the gearwheel (6), oriented in the axial direction of the tooth system (4), is carried out during the chip-removing machining, as a consequence of which movement the tool (7, 7′) sweeps over the tip surface (8), and the tool axis of rotation (Rz) is oriented at an axis intersection angle (Σ″) of 5° to 40° with respect to the workpiece axis of rotation (Rw). In this way, efficient and highly precise machining of the tip circle diameter is made possible. The invention also states a method for producing a gearwheel, in which the tooth system (4) is produced on a gearwheel blank (5) by means of hob peeling before machining of the tip circle diameter according to the invention, as well as a combination tool, in which a hob-peeling wheel for producing the gearwheel and a disk-shaped tool for machining the tip circle diameter according to the invention are combined with each other.

摘要： The present disclosure includes a part hold-down assembly for retaining an oversized part. The part hold-down assembly is aligned along a central force axis and applies a downward force onto the part. The part-hold down assembly includes a top plate, a bottom plate, and a compression assembly extending between the top and bottom plates. The compression assembly includes two, parallel biasing assemblies that extend along compression axes that are parallel to but offset from the central force axis. Each biasing assembly including an upper collar, a lower collar and a resilient biasing member, in one embodiment in the form of a coil spring, retained between the upper and lower collar. The parallel biasing assemblies are positioned on opposite sides from each other about the central force axis, and may be spaced away from the central force axis an equal distance.

摘要： A cutting tool includes a steel gear-shaped cutter which has cutting edges for die-cutting a fiber mat into a predetermined gear shape. The cutting edges include tooth-top, tooth-bottom and tooth-surface cutting edges, and. The cutter has an inclined cylindrical exterior shape so that its thickness gradually increases from the cutting edges toward the base end. V-shaped grooves are formed on the exterior surface and become shallower from the cutting edge toward the base end. The wedge angle (α1) of the tooth-bottom line from the tooth-bottom cutting edge to the base end is greater than the wedge angle (α2) of the tooth-top cutting edge surface from the tooth-top cutting edges to the base end. The thickness (W1) of the tooth-bottom cutting edge is greater than the thickness (W2) of the tooth-top cutting edge on the base-side end.

摘要： A gear includes teeth 3 to be engaged with teeth of a corresponding gear to transmit a rotational motion, in which a form (b) of a tooth root side of each tooth 3 includes: a first curved surface c which smoothly connects with a tooth surface a having an involute curve and has a profile represented by a curve which is convex in a direction opposite to the involute curve of the tooth surface a; and a second curved surface d which smoothly connects with the first curved surface c and has a profile defined by a quadratic function having a curve being convex in the same direction as that of the first curved surface c. Therefore, a stress generated on the tooth root side at the time of engagement with the teeth of the corresponding gear can be reduced, and the strength of the teeth can be increased.
