|---|
| 20120099939 | METHOD AND TOOL FOR MANUFACTURING FACE GEARS - 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. | 04-26-2012 |
| 20120098214 | DEVICE FOR SECURING A TOOL TO A SPINDLE - A tool securing device capable of clamping a tool to a machine spindle as well as assisting in the removal of a tool from a machine spindle, all in a tool-less manner. The tool securing device includes distal means to be releasably gripped by a machine draw bar as well as means to releasably engage a tool. | 04-26-2012 |
| 20120061926 | WORKHOLDING APPARATUS FOR WORKPIECE TRANSFER - A workholding apparatus comprising a chuck body, first jaw members and second jaw members wherein the second jaw members are shaped to grip a workpiece of a particular geometry. The first and second jaw members are constructed to enable easy, quick and manual replacement of the second jaw members with other second jaw members having different grip shapes so as to enable gripping of workpieces with different geometries. | 03-15-2012 |
| 20110301742 | ADAPTIVE CONTROL OF A MACHINING PROCESS - A method of determining a desired power level (P) as a function of relative tool to workpiece position, thereby enabling adaptive control advantages that were previously inaccessible for machining, such as bevel gear grinding, from solid applications. Preferably, set point power is expressed as a function of specific power (P′, P″) and roll position (Q) for a generated gear or as a function of specific power and plunge position for a non-generated (i.e. Formate) gear. Specific power is defined and preferably remains as defined during machining even as process conditions vary during machining. | 12-08-2011 |
| 20110272872 | CRADLE FOR MACHINING OF LARGE PINIONS - A cradle device for large pinion gears or blanks wherein a pinion may be supported and rotated for machining. The cradle device comprises one or more adjustable prismatic units each including a plurality of angular plates that are movable toward and/or away from one another along the width of the cradle device in order to raise and lower, and/or laterally shift, a pinion placed thereon so as to position the pinion for machining. | 11-10-2011 |
| 20110209573 | HYPOID GEARS WITH LOW SHAFT ANGLES - 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. | 09-01-2011 |
| 20110103911 | MANUFACTURING BEVEL GEARS - A method of manufacturing bevel gears with a tool, such as a tapered milling tool ( | 05-05-2011 |
| 20100290851 | RUNOUT COMPENSATION ON MACHINE TOOLS - 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. | 11-18-2010 |
| 20100273400 | METHOD AND DEVICE FOR REMOVING A SECONDARY BURR ON AN END-CUT WORK PIECE WHEEL - A method and a device for removing secondary burrs raised on the tooth flanks of a work piece wheel by a chamfering of the end tooth edges of said work piece wheel provides a tool wheel that rotationally meshes with the work piece wheel. Said tool wheel has cutting edges on its tooth flanks ( | 10-28-2010 |
| 20100272535 | ARRANGEMENT TO CONNECT A TOOL WHEEL AND A TOOL HOLDING FIXTURE - An arrangement for the non-rotational connection between a toothed tool wheel for the machining of end peripheral areas of tooth flanks, having an axis of rotation, and a tool holding fixture that can be rotationally driven around an axis of rotation. Said arrangement has an elastic means with a restoring force against which the direction of the axis of rotation of the tool wheel can be displaced relative to the direction of the axis of rotation of the tool holding fixture. | 10-28-2010 |
