Patent application number | Description | Published |
20080279642 | Tool for improved chip flow - A manner of reducing or eliminating chip packing in gear cutting tools, especially in bevel gear cutting tools wherein the back surfaces of at least some cutting blades are modified by the introduction of a rake angled surface and/or a hook angled surface thereby resulting in an opening-up of the gap 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. | 11-13-2008 |
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 |
20110103911 | MANUFACTURING BEVEL GEARS - A method of manufacturing bevel gears with a tool, such as a tapered milling tool ( | 05-05-2011 |
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 |
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 |
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 |
20120230791 | METHOD AND APPARATUS FOR MANUFACTURING BEVEL GEARS - Method and apparatus wherein the front machining of a gear blank ( | 09-13-2012 |
20120328383 | CONTINUOUS METHOD FOR MANUFACTURING FACE GEARS - 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. | 12-27-2012 |
20130039712 | BEVEL GEAR MANUFACTURE WITH FACE CUTTERS WITHOUT SWING AXIS MOTION - A method of machining bevel gears whereby machining of both flanks of a tooth slot and crowning of the tooth surfaces in the lengthwise direction are realized without an active pivot axis and by a modification of the conventional relationship between the radial and swivel basic settings during gear generating. | 02-14-2013 |
