摘要： PROBLEM TO BE SOLVED: To provide a gear processing method and a tool shaping method capable of eliminating waving in tooth form, and reducing gear noise. SOLUTION: In this processing method, a gear is manufactured in a gear generating method using a worm tool 21, with the phases of the worm tool 21 and a workpiece 22 shifted during processing, while simultaneously the worm tool 21 is moved in the workpiece axis direction. By moving the worm tool 21 in the tool axis direction, its phase to the workpiece can be shifted. For the worm tool 21, a tool trued in a processing machine, a tool trued outside the processing machine, an electrodeposition worm tool, or a cemented carbide hob or other hob can be used. For phase deflection quantity between the worm tool 21 and the workpiece 22, a 5-90 deg. range is preferable as rotation angle shift quantity of the worm tool 21 per rotation of the workpiece 22.

摘要： PROBLEM TO BE SOLVED: To eliminate such problems that a tool must be formed in a complicated shape or the number of processes must be increased in the generation of complicated tooth face such as bias tooth face in the production process for mass-produced gears and accordingly a cost is increased and an efficiency is decreased and such problems that, since the gear face is generated basically by the copying of the tooth face in a shaving process and a honing process for generating complicated gear faces such as bias gear face, the accuracy of the tools thereof and a difference of lots affect a gear face accuracy and accordingly a quality is not stabilized. SOLUTION: A complicated gear face such as bias gear face is generated by a worm-shaped tool, a corrective action to shift from a synchronous state is applied to at least one of a worm-shaped tool rotating shaft, a work rotating shaft, and a worm-shaped tool feed shaft operated in synchronous with each other during the generation of gear face by the worm-shaped tool, or at least a part of the gear face is generated in a complicated tooth face such as bias tooth face by the rotation or movement of either of a tool swing shaft and a tool shift shaft, the movement of a tool cut-in shaft used in combination with the rotation or movement, or the combination thereof.

摘要： PROBLEM TO BE SOLVED: To check a synchronous condition of a screw-shaped tool and a work, and accurately correct it by a proper correction quantity by electrically connecting a rotation detecting pulse coder of the screw-shaped tool and a rotation detecting sensor of the work to a synchronous correction control device. SOLUTION: A synchronous correction control device 14 performs a comparison operation on respective pulses inputted from a rotation detecting pulse coder 7 of a hob 1 and a rotation detecting sensor 12 of a work 8 and the necessary pulse number from a theoretical value of the previously inputted rotation ratio of the work 8 to the hob 1, and its calculating value is inputted to a main control device 13 as a corrective pulse signal, and the main control device 13 interruptedly controls rotation of a motor 10 for a work on the basis of this input signal. Therefore, even if there is slight turbulence of a synchronous condition of the hob 1 and the work 8, it is immediately corrected, and a synchronous difference between the hob 1 and the work 8, that is, a generating gear can be delicately corrected.

A hobbing head 8 is installed on the front side of the hobbing saddle 4 to vary the angle through an angle varying mechanism 7, a cutter arbor 10 driven in rotation by a hob driving mechanism 9 is supported at both ends on the hobbing head 8, and a grinding wheel 11 is installed thereon. The cutter arbor 10 is rotated within a range of 4,000-20,000 rpm, and the peripheral speed of the grinding wheel 11 is set within a range of 20-100 m/sec.

摘要： PROBLEM TO BE SOLVED: To provide a method for gear-wheel honing in which tooth doubling is carried out so that a working allowance becomes equal by simple formation, and by synchronously spinning a grinding stone gear-wheel and a worked gear-wheel with high accuracy, by a synchronous rotation by which a highly accurate gear-wheel is manufactured with efficiency and at a low cost.
SOLUTION: In this gear-wheel working method, a driving spinning phase is fixed by performing the engagement spinning of both spindles by synchronous control by driving the worked gear-wheel 2 and the grinding stone gear-wheel 1 together, by performing the mounting of the worked gear-wheel to the supporting shaft of the worked gear-wheel, by clamping the worked gear-wheel to the above supporting shaft of the worked gear-wheel, by measuring a spinning phase difference between the worked gear-wheel and the supporting shaft of the worked gear-wheel with a device for positioning the worked gear-wheel, by synchronizing the worked gear-wheel and the grinding stone gear-wheel by the controlling of each control motor and by doubling and spinning a spinning phase so as to cancel the spinning phase difference, in a condition in which the driving torque of the worked gear-wheel or the grinding stone gear-wheel is lowered to a degree not to receive cutting due to the grinding stone gear-wheel, by approaching the worked gear-wheel and the grinding stone gear-wheel up to the vicinity of a backlash zero position, by reading the spinning phase difference between the worked gear-wheel and the grinding stone gear-wheel at the vicinity of the backlash zero position and by making adjustment so as to cancel the spinning phase difference of each control motor between the worked gear-wheel and the grinding stone gear-wheel.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a dress gear tooth flank shape is not clearly transferred onto a workpiece tooth flank and accuracy is lowered when the number of teeth of a workpiece and the number of teeth of a dress gear are made different to be worked in gear wheel honing; and to provide a tool and a working method capable of accurately working even when the number of teeth of the workpiece and the number of teeth of the dress gear are made different to be worked.
SOLUTION: When the number of teeth of the workpiece and the number of teeth of the dress gear are made different to be worked in order to commonly use the dress gear or for other reasons, working can be accurately performed without lowering the accuracy by using the dress gear having the shape with the dress gear tooth flank required for the workpiece tooth flank desired.

摘要： PROBLEM TO BE SOLVED: To provide a precise and low-priced gear wheel working method and working machine.
SOLUTION: In a gear wheel honing work, a transmission error and an elastic effect between a gear wheel 2 to be worked/a grindstone gear wheel 1 and a motor are made very small by directly coupling the driving of the gear wheel 2 to be worked and the grindstone gear wheel 1 with the shaft of the motor, and the cumulative error of the gear wheel 2 to be worked is improved and rectified by the working. A structure is simple and a machine is low-priced. In addition, a meshing position where a working allowance is unified is easily detected by adjusting the driving torque of the axle motor of the gear wheel to be worked and/or that of the grindstone gear wheel while performing meshing rotation of the two gear wheels, thus meshing at the time of working is simplified and ensured. Further, since meshing is enabled while the grindstone gear wheel is continuously rotated, a working cycle time is shortened. In addition, a slip velocity is high, sharpness is improved, and working is precisely performed by setting a crossed axes angle at 15° or more.

摘要： PROBLEM TO BE SOLVED: To provide a gear honing processing method capable of reducing time required to manufacture a gear and ensuring surface roughness of its tooth flank. SOLUTION: In the processing method wherein a heat-treated work gear is processed by an internal gear type honing stick without sharpening a tooth by means of a worm type grinding tool, after a plunge cut is carried out such that the work gear is moved only in a radial direction of the work gear with respect to the honing stick (area C), a conventional cut is applied such that the work gear is moved in a direction with respect to an axis of the work gear and in the radial direction with respect to the honing stick alternately or at the same time (area D).
