    • 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.

    • 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.

    • 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.

    • 要解决的问题:为了解决在将工件的齿数和装饰齿的齿数设定为工件齿面的情况下,不会将修饰齿轮齿面形状明显地转移到工件齿面上的精度降低的问题 在齿轮珩磨方面做了不同的工作; 并且提供即使当工件的齿数和装饰齿轮的齿数不同而被加工时能够精确地工作的工具和工作方法。

      解决方案:为了通常使用连衣裙或其他原因,当工件的齿数和连衣裙的齿数不同时,可以精确地进行加工,而不会降低精度 通过使用具有所需的工件齿面所需的连接齿轮齿面的形状的连衣裙。 版权所有(C)2006,JPO&NCIPI
