Abstract:
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.
Abstract:
A cutter disk having cutting blades oriented on its circumference with the cutting edges of the blades oriented perpendicular to the axis of rotation of the cutter disk thereby representing a plane which can be oriented to a work piece (e.g. face gear) under an angle equal to the pressure angle of the mating face gear set's pinion, and, which can be rotated around a virtual pinion axis to generate a tooth flank on the work piece.
Abstract:
It is described a curvic coupling (400) for rotational coupling, the curvic coupling comprising: plural teeth (402, 403) arranged in a circle and protruding from a circle plane extending in a radial direction (407) and a circumferential direction (409), wherein a side surface (411) of a tooth (403) of the plural teeth is opposite to a side surface (413) of another tooth (402) of the plural teeth, wherein the tooth (403) is adjacent to the other tooth (402) and separated from the other tooth by a separating surface (404), wherein the separating surface comprises a flat surface (405) lying in the circle plane, wherein the separating surface (404) comprises a central protrusion (423) between the side surface (411) of the tooth (403) and the side surface (413) of the other tooth (402), wherein the protrusion (423) protrudes from the circle plane.
Abstract:
The present invention is directed to a unique gear set (10) including a conical involute pinion (14) and a mating face gear (12). The mating face gear has an axis (GA) whose location and orientation is usually configured as intersecting with or slightly offset from the pinion axis (PA). The pinion teeth (16) are formed as involute helicoids generated from a base cylinder. The mating face gear teeth are defined by the shape of the mating conical pinion teeth surface at the time when the two mating gears are specifically positioned so as to perform synchronous rotations about their respective axes of rotation. This arrangement allows the gears to mesh and transmit high torque at high speeds through an angle as required in helicopter transmissions and the like.
Abstract:
In a face gear transmission with a cylindrical pinion and a face gear meshing therewith the toothing of the face gear is derived from a theoretical profile (22) of a pinion with an infinitely small thickness by moving the centre of this pinion along an imaginary axis which then coincides with the axis of rotation of the cylindrical pinion. The teeth of the face gear are crowned so as to achieve the required tooth clearance. The shape of the teeth of the face gear is such that upon the movement of the theoretical pinion profile (22) in the direction of the imaginary axis of rotation, starting from a defined diameter between the maximum and the minimum diameter of the toothing of the face gear, the centre of the theoretical pinion profile undergoes a displacement (p1, p2) at the same time at right angles to the imaginary axis of rotation in the direction towards the toothing of the face gear.

Die Erfindung betrifft eine Vorrichtung zur Verzahnung von Werkstücken (1, 1', 1'', 1''') mit einer Werkzeugspindel und einer Werkstückspindel, die in einem festen Drehzahlverhältnis zueinander drehangetrieben sind und deren Achsen (2, 4) einen Achsabstand (R) haben, wobei die Werkzeugspindel mindestens einen ein Schneidwerkzeug (5) aufweisenden Messerkopf (3) trägt, der auf das Werkstück (1, 1', 1'', 1''') zustellbar ist und während des spanabhebenden Bearbeitens des Werkstückes (1, 1', 1'', 1''') in einer Vorschubrichtung (V) kontinuierlich verlagerbar ist, wobei die Vorschubrichtung (V) eine in der Achsabstandsrichtung (R) verlaufende Radialkomponente aufweist. Zur Erzeugung von Stirnverzahnungen ist vorgesehen, dass die Werkzeugspindelachse (4) derart um eine im Wesentlichen parallel zur Werkstückspindelachse (2) verlaufende Neigungsachse (12) schwenkbar ist, dass sich ihr Neigungswinkel (φ) um diese Achse (12) einhergehend mit der Änderung des Achsabstandes (R) ändert.
Abstract:
Methods and apparatus are provided for producing a curved tooth. Apparatus are adapted to perform a method that includes the steps of providing a workpiece, providing a tool, and providing relative movement between the tool and the workpiece such that the tool moves along a first curved path relative to the workpiece to define a first curved surface of a tooth in the workpiece. The relative movement can be accomplished by substantially simultaneous translation of at least one of the tool and the workpiece along a first linear axis and a second linear axis that is perpendicular to the first linear axis. Methods are also disclosed for compensating for deviations in a tool path.
