The tooth profiles at the tooth fac

确保齿轮的齿面上的齿廓在与K的值相对应的部分处适当地彼此接触，所述K的值与y的值相关联，外齿轮的齿在内齿轮的齿槽中移动通过y的值。这是基于这样的事实，即在图6的点Q处，在彼此接触的齿面上的齿廓彼此接触。例如，如图11所示，相对于该点Q彼此对称，并且，通过上述在齿面上限定齿廓的过程，柔性外齿轮的齿顶P位于所获得的点上。相对于刚性内齿轮的齿，通过从点B延伸超过点Q的直线BQ两倍，并且两个齿廓的点Q处的切线的倾角相等。<br>当沿着齿迹方向观察时，由包络线从其顶点限定的复合曲线的部分对应于从挠性外齿轮的开口到端部的外侧附近的部分的齿的啮合。另外，合成曲线的其余部分对应于设置在端部外侧附近的幻影齿的连续接触。在隔膜的端部附近设置限制部的情况下，在该位置上不存在实际的齿，因此，齿的啮合是假想的。<br>无花果 图12、13和14示出了当在端部33上选择了限制部分时的齿的齿廓的啮合。图。图12示出了其在开口31处的旋转截面上（在无偏差的截面上）的啮合。图13示出了齿迹旋转中心部分32上的啮合。图14示出了在隔膜的齿迹的端部的部分33上。从这些图中可以看出，在沿着齿迹方向旋转的各个部分中，齿的连续接触的各个部分形成为与包络线和齿的每个运动轨迹的接触程度有关。各个部分。<br>通过将这些附图与相应的附图进行比较可以明显看出。参照图6、7和8，其中沿常规牙齿的齿迹方向在相同位置的各个移动轨迹，在采用本发明的牙齿轮廓的情况下，可以认为是沿齿的所有部分连续接触。建立了沿齿迹方向的旋转，并且没有发生诸如牙齿干涉之类的缺陷

The tooth profiles at the tooth faces of the gears are assured to contact with each other properly at sections corresponding to the values of Kassociated with the values of y through which the teeth of the external gear move in the tooth grooves of the internal gear. This is based on the facts that the tooth profiles at tooth faces contacting with each other at the point Q of FIG. 11, for example, are symmetrical with each other with respect to this point Q, and that, through the above-mentioned process of defining the tooth profiles at the tooth faces, the tooth apex P of the flexible external gear is on the point obtained by extending two times the straight line BQ beyond the point Q from the point B with respect to the teeth of the rigid internal gear, and the inclinations of the tangents at the point Q of the both toot profiles are equal.<br>When viewed along the tooth trace direction, the portion of the composite curve defined by the envelope from the apex thereof corresponds to the meshing of the teeth from the opening of the flexible external gear to the portion in the vicinity of the outside of the end portion of the diaphragm, while the remaining portion of the composite curve corresponds to a continuous contact of the phantom teeth provided in the vicinity of the outside of the end portion. Where the limit section is provided in the vicinity of the end portion of the diaphragm, no actual teeth exist on this position and therefore the meshing of the teeth thereof is an imaginary one.<br>FIGS. 12, 13 and 14 show the meshing of the tooth profiles of teeth when the limit section is selected on the end portion33. FIG. 12 shows the meshing thereof on the section of rotation at the opening 31 (on the section of non deviation), FIG. 13 shows the meshing on the central section 32 of rotation of tooth trace, and FIG. 14 shows that on the section33 of the end portion of tooth trace of the diaphragm. As can be seen from these figures, in the respective sections of rotation along the direction of tooth trace, respective parts of the continuous contact of the teeth are formed in accor dance with a degree of contact of the envelope and each of the moving loci of the respective sections.<br>As is apparent by comparing these figures with corre sponding FIGS. 6, 7 and 8 wherein the respective moving loci of the same positions along the direction of tooth trace of the conventional teeth, where the tooth profiles of the present invention are employed, it can be regarded that a continuous contact along all of the sections of rotation in the direction of tooth trace is established and that no defect such as the tooth interference occurs

确保齿轮齿面处的齿廓在与外齿轮齿在内齿轮齿槽中移动所通过的y值相关联的k值相对应的截面处正确接触。这是基于这样的事实，例如，在图11的点Q处相互接触的齿面处的齿廓相对于该点Q彼此对称，并且通过在齿面处定义齿廓的上述过程，柔性外齿轮的齿尖P位于从B点到刚性内齿轮齿的直线BQ的两倍于Q点的距离得到的点，两个齿廓的Q点切线的倾斜度相等。<br>沿齿迹方向观察时，由包络线从其顶点定义的复合曲线部分对应于从柔性外齿轮开口到隔膜端部外侧附近部分的齿啮合，而复合曲线的其余部分对应于在端部外部附近提供的假牙的连续接触。如果极限部分设置在横膈膜的端部附近，则此位置上不存在实际齿，因此其齿的啮合是假想的。<br>无花果。当在端部33上选择极限截面时，12、13和14显示齿廓的啮合。图12所示为其在开口31处的转动截面上的啮合（在无偏截面上），图13所示为齿迹转动的中心截面32上的啮合，图14所示为隔膜齿迹端部33上的啮合。从这些图中可以看出，在沿齿迹方向旋转的各个部分中，齿的连续接触的各个部分是根据包络线和各个部分的运动轨迹的接触程度而形成的。<br>通过比较这些图和相应的图可以明显看出。6、7和8，其中，在使用本发明的齿廓的情况下，沿着常规齿的齿迹方向的相同位置的相应运动轨迹，可以认为，沿齿迹方向的所有旋转部分都建立了连续接触，并且没有出现齿干涉等缺陷<br>
