    Abstract: A transmission gear has a tooth surface formed of a free-form surface instead of an involute surface and a root area formed of a free-form surface instead of a trochoid surface. With such a transmission gear, the fatigue strength against contact pressure can be increased by reducing the Hertzian stress in the area around the meshing point of the tooth surface. The tooth surface is formed of a free-form surface in which the smallest radius of curvature in an area around a mating pitch point is maximized, and the fatigue strength against bending can be increased by reducing the bending stress at a tooth root portion of the bottom land. In addition, the gear noise can be reduced. The bottom land is formed of a free-form surface in which the smallest radius of curvature in an area around a tooth root is maximized.

    Abstract translation: 传动齿轮具有由自由曲面形成的齿面，而不是渐开线面，而是由自由曲面形成的根部区域而不是次摆线面。 通过这样的变速齿轮，可以通过减小齿面的啮合点周围的区域的赫兹应力来提高抵抗接触压力的疲劳强度。 齿表面由自由曲面形成，其中在配合节点周围的区域中的最小曲率半径最大化，并且可以通过减小弯曲的齿根部分处的弯曲应力来增加抗弯曲疲劳强度 底部土地 此外，可以减少齿轮噪音。 底部区域由自由形状的表面形成，其中齿根周围区域中最小的曲率半径最大化。

    Abstract: A method of manufacturing a part with a tooth profile by cold forging includes an initial step of forming a initial tooth profile and a finishing step of forming a completed tooth profile by sizing. Between the initial step and the finishing step, is an intermediate step tooth thickness of the initial tooth profile is either maintained or reduced by 10% or less from the tooth thickness of the initial tooth profile. In the intermediate step an addendum part is expanded beyond the initial tooth profile by cold forging.

    Abstract: An elongated stud has an axial bore down which an inspection probe is rotated and translated on the end of a shaft which is moved through gearing with a pair of motors. Encoders on the motors coordinate the signal from the probe at a single station which manifests the sensed conditions of the stud at positions within the bore.
