| 20080213054 | METHOD AND SYSTEM TO MANUFACTURE ORIENTED INTERNAL AND EXTERNAL GEAR TEETH - A system and method for forming a feature on an inner surface of a gear includes a sensor for sensing the position of a feature on the gear, a cutting station having a cutting tool for forming the feature on the inner surface of the gear, and a controller. The controller is operable to determine an amount of rotation necessary to rotate either the gear or the cutting tool such that the feature on the inner surface of the gear is formed at a desired orientation relative to the feature on the outer surface of the gear. | 09-04-2008 |
| 20100221079 | MACHINE TOOL AND PROCESS FOR MACHINING A WORKPIECE - The present invention relates to a machine tool and a corresponding process for machining a workpiece by means of one or more tools controlled by means of control data, the machine tool comprising at least 5 simultaneously controllable axes. A control device being suited to control the tool supported in a support means by means of the control data along a tool path to remove material from the workpiece clamped in a clamping means. The machine tool being suited to machine a first workpiece to provide the first workpiece with a first gearing, the first workpiece being a counter piece to a second workpiece having a second gearing. The machine tool also comprising a test system suited to determine after and/or during the machining of the first workpiece on the machine tool whether a current geometry, in particular a current tooth flank geometry and/or current tooth gap geometry, of the first gearing of the first workpiece differs from a target gearing geometry, in particular from a target tooth flank geometry and/or target tooth gap geometry, of the first gearing of the first workpiece. | 09-02-2010 |

| 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 |
| 20130156521 | GEAR MACHINING APPARATUS AND GEAR MACHINING CONDITION SETTING DEVICE - A gear machining condition setting device receives a feeding amount determining parameter and a cutting speed determining parameter. A storage unit stores a cutting-in amount calculation formula representing a relation between a cutting-in amount and a characteristic value determined based on a feeding amount and the feeding amount determining parameter. The feeding amount of the hob, corresponding to the cutting-in amount, is computed using the cutting-in amount calculation formula. Further, the storage unit stores data of a constant temperature curve representing a relation between the cutting-in amount and the cutting speed where a cutting edge of the hob is set at a predetermined temperature. Using the data, the cutting speed is computed based on the cutting-in amount and the cutting speed determining parameter with reference to the constant temperature curve. | 06-20-2013 |
| 20130202377 | METHOD FOR OPERATING A MACHINE TOOL AND MACHINE TOOL - The present disclosure relates to a method for operating a machine tool, in particular a gear cutting machine, with at least two machine tables, with at least one common counter-support and with at least two counter-bracket arms, wherein the clamping forces are controlled and/or regulated at the respective position in dependence on the current process and in dependence on the process forces necessary according to the current process. Furthermore, the present disclosure relates to a machine tool, in particular a gear cutting machine. | 08-08-2013 |
| 20130216321 | OPTIMIZED CROWNING IN BEVEL GEAR WHEELS OF A BEVEL GEAR TRANSMISSION - The invention relates to a method for producing a bevel gear wheel, in particular for rudder propellers, the teeth of which have a macro geometry specific to the gear wheels, the teeth of which can be described by flank and profile lines, the flanks of which have a tooth flank micro topography and the bearing surface of which represents the contact region of the inter-meshing teeth. The crown of a tooth flank corresponds to the elevation of the tooth flank center with respect to the tooth flank edge, wherein the course of the height and width crowns of the flank surface is substantially shaped like a circular arc. By means of precise material removal, the micro topography of the tooth flank and thus the bearing surface is optimized firstly in that the material removal is carried out such that the end relief on the tooth flank surface is reduced toward the tooth heel side and the tooth toe side, an area having a greater length and width comes into engagement on the flank and thus an enlarged bearing surface is present, and secondly in that the course of the crown the crown of a tooth flank follows an approximately logarithmic, elliptical and/or an exponential curve shape, which runs through the point of contact, when the ease-off is viewed with no load, in a longitudinal section in the flank sectional surface and/or in a profile section in the profile sectional surface. | 08-22-2013 |
| 20130336739 | Method Of Generating Gear Teeth, And A Gear-Cutting Machine That Is Operable According To Said Method - The invention concerns a method of generating gear teeth, wherein a workpiece which is to receive a toothed profile and a cutting tool are advanced toward each other in a rolling feed motion until each tooth flank of the gear profile has been generated after several passes of the tool, wherein in each pass a cut surface containing at least one flank cut is generated on the workpiece, wherein an auxiliary motion is superimposed on the rolling motion, which has the effect that the flank cuts generated in at least two immediately consecutive passes will be connected to each other. In addition, the invention also concerns a gear-cutting machine with the requisite control features to perform the method. | 12-19-2013 |
| 20140079498 | METHOD FOR HOB PEELING AND CORRESPONDING DEVICE HAVING A HOB PEELING TOOL - A method and an apparatus for skiving a work piece that has a rotationally-symmetric, periodic structure, by applying a skiving tool. The skiving tool has a tapering collision structure. During skiving, a coupled relative movement of the skiving tool in relation to the work piece is performed. The skiving tool is rotated about a first rotation axis and the work piece is rotated about a second rotation axis. A negative tilt angle is set during skiving, and the first rotation axis runs skew with respect to the second rotation axis. | 03-20-2014 |
