    • PROBLEM TO BE SOLVED: To provide technology for efficiently machining a tooth face of a geared member. SOLUTION: A tooth face machining method is used for machining the tooth face formed on a side face of a cylindrical geared member and extending along a center axis line A2 of the geared member. The machining method includes: a first cutting step of moving an end mill 30 in parallel to the center axis line A2 of the geared member while keeping a direction of a center axis line A1 of the end mill 30 constant to cut the tooth face of the geared member by a side face edge of the end mill 30; a rotating step of rotating the geared member around the center axis line A2 by a predetermined angle; and a second cutting step of moving the end mill 30 in parallel to the center axis line A2 of the geared member while keeping the direction of the center axis line A1 of the end mill 30 in the same direction as in the first cutting step to cut the tooth face of the geared member by the side face edge of the end mill 30. The machining method can efficiently machine the tooth face of the geared member by keeping the center axis A1 of the end mill 30 constant. COPYRIGHT: (C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a cutting means for spiral bevel gears which does not cause an error in pitch dimension. SOLUTION: In a single indexing, cutters are circularly disposed on a cutter head so that all cutters can move through a tooth groove to be formed in cutting a spiral bevel gear. Then, a workpiece is rotated by one by one pitch, and the continuously rotating cutter head cuts a next tooth groove. Since all cutters are not formed in intended shapes nor positioned in intended attitudes, different structures are formed in a tooth face which causes a deviation in pitch dimension. To avoid this problem, a face milling cutting method is proposed. In this case, the cutter head takes a posture for the previous tooth groove positioned at the same angle, about its axis, relative to the tooth groove to be formed. As a result, though all the tooth grooves are not generally accurate, the surface structures thereof become the same and an error is less caused in pitch dimension. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种螺旋锥齿轮的切割装置,其不会引起螺距尺寸的误差。 解决方案:在单个分度中,切割器圆形地设置在刀头上,使得所有切割器可以移动通过切割螺旋锥齿轮而形成的齿槽。 然后,工件一个接一个地旋转,连续旋转的切割头切割下一个齿槽。 由于所有的切割器都不是以想要的形状形成,也没有按预定的姿态定位,所以在齿面上形成不同的结构,这导致俯仰尺寸的偏差。 为了避免这个问题,提出了一种面铣切割方法。 在这种情况下,刀头相对于要形成的齿槽以相对于其轴线为相同角度的先前齿槽采取姿势。 结果,虽然所有的齿槽通常不准确,但是其表面结构变得相同,并且在螺距尺寸上引起的误差较小。 版权所有(C)2005,JPO&NCIPI
