20120148360 | DEVICE AND METHOD FOR HOB PEELING INTERNALLY GEARED WHEELS AND RELATED PEELING WHEEL - The invention relates to a device for generating teeth of workpieces ( | 06-14-2012 |
20140050546 | Apparatus And Method For Cutting Teeth In Workpieces And Associated Tool Set - A method for cutting teeth in workpieces, wherein, in a roughing operation, a substantially uncut blank receives rough teeth using a cutting tool having cutting teeth. Operation teeth are produced, the tooth width of which is defined by the spacing between the flanks of the teeth and is greater than the target dimension. In a subsequent deburring operation, a chamfer is incorporated into the end face edge of the tooth flanks, accompanied by the removal of an end face burr. Lastly, in a smoothing operation, the tooth width of the teeth is brought to the target dimension by machining the tooth flanks. | 02-20-2014 |
20150314382 | METHOD FOR DETERMINING THE FLANK FACE CONTOUR OF A GEAR SKIVING TOOL, GEAR SKIVING TOOL AND USE THEREOF - A clearance angle, of a blade-like tool or tool tooth of a tool for hob peeling workpieces is determined by defining the rake face contour of the tool and calculating the progression of path movement of the rake face during chip-breaking hob peeling, taking into account a pre-determinable transmission ratio between the tool and the workpiece determined by the respective number of teeth, and the desired tooth cross-section contour of the tool, and determining a tangential speed for points of the cutting edge of the tool during chip-breaking, wherein hob peeling is determined in the form of vectors that are displayed graphically as bundles for each point on the cutting-edge and a closed envelope surface is determined, which plus a desired clearance angle is selected as the shape for the flank face contour of the tool or of the flank face of the tool tooth. A tool is also provided. | 11-05-2015 |
