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:
Disclosed is a gear pair set comprising low shaft angle and offset bevel gears and a method for their manufacture including determination of the appropriate gear and pinion blanks and the basic machine settings for their manufacture. The pair of bevel gears comprises a first member and a second member wherein the members of the pair have a shaft angle in the range of greater than 0° to 30°, preferably greater than 0° to 20°, and have an offset in the range of greater than zero to the sum of half the mean pitch diameters of the two members of the bevel gear pair.
Abstract:
A method of determining axial and/or radial runout due to workholding equipment and compensating for such runout during machining of a gear wherein axial and/or radial runout compensations are executed during the machining of each individual tooth slot.
Abstract:
A continuous method of manufacturing a face gear utilizing a tool, representing a plane which can be oriented to a face gear workpiece under an angle equal to the pressure angle of the mating pinion member of the gear set (e.g. the face gear set), and, which can be rotated around a virtual pinion axis to generate a tooth flank on the workpiece. The tool is a face cutter which performs a continuous indexing motion with equal hand of rotation of cutter and workpiece (e.g. face gear) thereby describing a hypocycloid path of motion and an indexing ratio of two cutter rotations during one workpiece gear rotation which will produce straight lines along the face width of the face gear.
Abstract:
Method and apparatus wherein the front machining of a gear blank (40) are carried out on a CNC bevel gear generating machine (44) utilizing the motions available in such machines with minimal modifications to the existing machine tool.
Abstract:
A method of manufacturing bevel gears with a tool, such as a tapered milling tool (16), wherein the tool is located at a position offset (R w ) from the center position of a conventional face milling cutter and the tool follows a path, such as a circular arc path, during machining.
Abstract:
A manner of reducing or eliminating chip packing in gear cutting tools, especially in bevel gear cutting tools wherein the back surfaces (D1) of at least some cutting blades are modified by the introduction of a rake angled surface (D2) and/or a hook angled surface (D3) thereby resulting in an opening-up of the gap (86) between successive cutting blades in a direction radially or axially away from the cutting tool. Such an opening-up facilitates the removal of chips from between the cutting blades as the cutting tool rotates during cutting.
Abstract:
Die Erfindung betrifft ein hochübersetzendes Kegelradgetriebe nach dem Einzelteilverfahren hergestellt, mit Ritzelzähnezahlen zwischen (1) und (4) welches einen Achsversatz zwischen den Drehachsen von Ritzel und Tellerrad besitzt und dessen Ritzel als eine kegelige Schnecke ausgeführt ist, die im wälzenden Verfahren hergestellt wurde während das Tellerrad formverzahnt ist. Erfindungsgemäß ist vorgesehen, dass der Seelendurchmesser des Ritzels an der Ferse mindestens der doppelten Zahnhöhe an der Ferse entspricht und ein Einstich die Ritzelzähne und ihre Anbindung am Lagerschulterabsatz beziehungsweise dem Ritzelschaft trennt.
Abstract:
A method and cutting tool for producing spiral toothed face couplings whereby a two-part cutter and a two-part machine tool spindle are not needed. The process includes a set-over between the cutting of convex (41) and concave (43) tooth surfaces and the tool (59) comprises inside and outside cutting blades positioned in a single cutter head blade slot (57) and separated from one another by a blade spacing angle (51).
Abstract:
An axial hob (14) with cutting teeth (16) which are arranged around a cylinder (19) in a helical pattern. The cutting front (18) is perpendicular to the helix. The re-grindable blade thickness is oriented in the direction of the helix lead direction. While the tool rotates, the active cutting front changes from one blade to the next which, depending on the hand of rotation, is an advanced or retracted position. However, the rotation will not give the individual blades a chip removing motion but only position the following blade in an advanced or retracted location, such as in a gear slot to be machined.
