    • An induction hardening apparatus for inductively heating and quench hardening a crankshaft includes an arrangement of two workstations similarly configured and a robotic device indexing the crankshaft from a first workstation to a second workstation. The induction hardening apparatus is designed with a single induction coil located at the first workstation for the sequential induction heating and quench hardening of the pins of the crankshaft. At the second workstation, a single induction coil is used for the bearing surfaces of the crankshaft. One feature of the present invention is that the induction coils do not contact the surfaces of the crankshaft which are being inductively heated and quench hardened. Crankshaft dimensions and geometry are programmed into servodrive systems which move the corresponding coil in X and Y directions accurately tracing the orbit or path of each pin and each bearing surface. Another feature of the present invention is the use of an offset 180 degree coil which provides improved heating patterns in less time than traditional 90 degree coils.
    • 用于感应加热和淬火淬火曲轴的感应淬火设备包括类似配置的两个工作站的布置以及将曲轴从第一工作站分配到第二工作站的机器人装置。 感应淬火装置设计有位于第一工位的单个感应线圈,用于曲轴的销的顺序感应加热和淬火硬化。 在第二工作站,单个感应线圈用于曲轴的轴承表面。 本发明的一个特征是感应线圈不接触正被感应加热和淬火硬化的曲轴的表面。 曲轴尺寸和几何形状被编程到伺服驱动系统中,其在X和Y方向上移动相应的线圈,精确地跟踪每个销和每个支承表面的轨道或路径。 本发明的另一个特征是使用偏移180度线圈,其在比传统的90度线圈更短的时间内提供改进的加热模式。

    • An induction-hardening machine for the contour hardening of cross-axis, intersecting-axis and nonintersecting-axis gears such as hypoid gears includes a programmable logic control unit, a source of quench liquid and a high-frequency induction generator which are operably connected to a high-frequency induction coil which is disposed at an inclined angle above the horizontally disposed workpiece (hypoid gear). Fluid connections are made between the source of quench liquid and the induction coil for the rapid delivery of quench liquid. The support platform for the hypoid gear is connected to a rotary drive motor and with the hypoid gear rotating at approximately 900 to 1800 RPM the induction coil is energized with four low energy pulses of relativley short duration. The final heating step is a high energy pulse followed immediately by the quenching step. The induction coil is also offset from the geometric center of the gear and it is this offset and the inclined angle of the induction coil which address the heel to toe tooth differences and the spiral configuration of a hypoid gear.
