摘要： The invention overcomes undesirable backlash effects in gear generators which cut gears by climb milling (i.e., with cutter blades rotating in the same direction as the work), these undesirable backlash effects being initiated by the intermittent cutting torques that tend to move the work momentarily ahead of the generating drive train as each blade is in the cut. Instead of a conventional spindle brake to oppose the cutting torques, an auxiliary motor in proximity to the work spindle end of the generating train applies torque to the train in the same direction as it is being driven by the main drive motor, and in the same direction as the cutting torques, thereby maintaining tightness in that portion of generating train which controls work spindle rotation by keeping the train gears with their "coasting" sides in contact rather than trying to keep their "driving" sides in contact.

摘要： A power skiving method wherein three-dimensional cutter rotations relative to gear workpiece tooth flank surfaces are carried out so as to reposition the cutter relative to a gear workpiece so as to achieve a decrease and/or an increase in the pressure angle of the tooth flank surfaces. The method can be applied independently to left and right flank surfaces of a tooth slot or the rotations may be superimposed on one another to realize pressure angle corrections on both tooth flanks of a tooth slot.

摘要： A method of producing a tooth flank surface on gear teeth by controlled removal of stock material from a work gear with a tool with the work gear and the tool being movable with respect to one another along and/or about a plurality of axes. The tool and work gear are engaged with one another and then moved relative to one another in a generating motion along and/or about the plurality of axes. Stock material is removed from the work gear to produce the tooth surface on the work gear. The generating motion along and/or about the plurality of axes comprises motion along and/or about at least one of the axes with the motion being defined by a function having a first level component and a second level component. The first level component defining a maximum flank form deviation amplitude for each tooth of the work gear, and the second level component defining a modification of the tooth surface of each tooth of the work gear.

摘要： Pericyclic transmission having at least one input shaft (58) rotatable about an axis of rotation and at least one inclined bearing seat (55, 56) secured to the input shaft with the inclined bearing seat being oriented at an inclination angle with respect to the axis of rotation of the input shaft. An input gear (52, 54) is attached to each inclined bearing seat with the input gear being oriented at the inclination angle and having an axis of rotation inclined to the axis of rotation of the input shaft by the inclination angle whereby upon rotation of the input shaft, the input gear performs at least a nutating motion. The transmission also includes an intermediate gear (51, 53) in mesh with the input gear with the intermediate gear having an axis of rotation coincident with the axis of rotation of the input shaft. The intermediate gear communicates with a transmission output.

摘要： A toothed workpiece chamfering device having a chamfering head (2) which includes a first axis of rotation (B) for rotation of a first chamfering tool (6) and a second axis of rotation (T) for rotation of a second chamfering tool (8) wherein the first and second chamfering tools are of different types and their respective material removal methods are also different from one another. Preferably, the first and second axes of rotation are not coincident with one another and in a more preferred arrangement, the first tool axis and the second tool axis are arranged perpendicularly to one another.

摘要： A process for improving the excitation behavior of a ground bevel gear set by altering the surface structure of a gear set member from tooth slot to tooth slot (Teeth 1-3). The method comprises shifting the roll-positions in a way that not every facet or flat (F) is positioned the same way on each flank (2) and/or changing the distances of the roll angle along a tooth slot (delta RPj) whereby flats are spaced unequally (i.e. varying widths) along the tooth. One or more additional processes for altering the surface structure may be included.

摘要： A skiving tool comprising a cutter head (2) having a plurality of cutter blade mounting and positioning slots (8) arranged spaced, preferably equidistant, about the periphery (7) of the cutter head with the blade slots, and hence the cutting blades (4), preferably oriented perpendicular to the axis of rotation (A) of the cutter head. Alternatively, the blade slots may be inclined from the perpendicular orientation by less than 50 degrees, preferably less than 20 degrees, thereby forming a conical shaped cutter. Additionally, the blade slots may be positioned to extend radially from the cutter head axis whereby the longitudinal axis of a cutter blade will intersect the cutter head axis, or the blade slots may be radially offset from the cutter head axis. The blade slots may have any cross-sectional shape such as square, rectangular or those types having generally V-shaped seating surfaces (10) comprising a pair of angled mounting surfaces (12, 14) each less than 90 degrees. In contrast to known cutting blade configurations, the cutting blade (4) of the present invention has its cutting face (16) formed in a surface of the cutting blade that is located opposite to the seating surface or V-shaped seating surfaces (13, 15) of the cutting blade.
