Skiving of cylindrical gears

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. ...

Bevel gear flank surface structure shift

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. ... The Gleason Works

Lock spring and cutting tool having a lock spring

A cutter head (4, 6) having a lock spring (30) utilized with an adjustment screw (16) for preventing the adjustment screw from loosening during machining. Once positioned by turning the adjustment screw, a cutting blade (8) will not change position in a mounting slot (10) due to a loosening adjustment screw.. ... The Gleason Works

Heat treatment of steel parts, particularly friction-welded steel parts

A heat treatment process for a non-quench hardened steel article or friction-welded steel article including normalizing and annealing steps whereby uniformity of microstructure and hardness are significantly improved.. . ... The Gleason Works

Compensation device and clamping device for workpieces equipped with a compensation device of this type

The invention relates to a compensation device for the flat-compensated clamping of a workpiece, in particular a toothed workpiece or a workpiece to be toothed, carried out via a clamping device defining a clamping axis, said workpiece having an axis of rotation and abutting a contact surface of the compensation device with a flat side, wherein the workpiece axis of rotation is coaxially centered to the clamping axis when the clamping device is actuated, and any deviations arising therefrom of the abutting flat side from an orthogonality to the workpiece axis of rotation are compensated by a deflection movement carried out at the compensation device, wherein the contact surface has at least three contact areas spaced apart from one another and the deflection movement comprises an axial movement of the contact areas.. . ... The Gleason Works

Cutter build and truing machine

A cutter build and truing machine (22) comprising a mechanism (52, 54) to position cutting blades (98) by moving the blades in either direction in a mounting slot (96) of a cutter head (94). The machine further includes a torque spindle (62) and driver (66) to automatically tighten or loosen clamp bolts (102).. ... The Gleason Works

Axial hob with multi-revolution cutting teeth

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 Gleason Works

Machine spindle with ejecting means

A workholding apparatus (10) wherein a draw bar (22) effects chucking and de-chucking of a workpiece (w) and wherein un-seating of the workholding apparatus is effected by piston-like mechanisms (30) located in a machine spindle (2).. . ... The Gleason Works

Method of grinding gears

A method of grinding the tooth slots of a workpiece with a freshly dressed grinding wheel wherein dual-machining of tooth slots is eliminated. The method comprises grinding the first few slots of a gear at a corrected depth amount which accounts for the rapid wear and other conditions of the freshly dressed grinding wheel wherein for a first number of tooth slots (e.g. ...
