    • An over running clutch assembly for an electrical switching apparatus is provided. The over running clutch assembly includes a sprocket and a hub assembly. The hub assembly is rotatably coupled to the sprocket and structured to rotate in a charging direction relative to the sprocket. The sprocket is fixed to a motor shaft. The hub assembly is structured to be disengagably fixed to a cam shaft in the charging assembly. A manual charging handle is also coupled to the cam shaft and is structured to rotate the cam shaft in a charging direction. In this configuration, an operator may charge the closing springs of the electrical switching apparatus using either the handle assembly or the motor. When the handle assembly is used to charge the closing springs, the cam shaft causes the hub assembly to rotate over the sprocket. Thus, the rotation of the cam shaft is not transferred to the motor. When the motor is used, the motor turns both the sprocket and the hub assembly. The hub assembly transfers the rotational force from the motor to the cam shaft.
    • 提供了一种用于电气开关装置的超行驶离合器组件。 过行驶离合器组件包括链轮和轮毂组件。 轮毂组件可旋转地联接到链轮并且被构造成相对于链轮在充电方向上旋转。 链轮固定在电机轴上。 轮毂组件被构造成可分离地固定到充电组件中的凸轮轴上。 手动充电手柄也联接到凸轮轴并且被构造成在充电方向上旋转凸轮轴。 在这种结构中,操作员可以使用手柄组件或电动机对电气开关装置的闭合弹簧进行充电。 当手柄组件用于对闭合弹簧充电时,凸轮轴使轮毂组件在链轮上旋转。 因此,凸轮轴的旋转不会传递到电动机。 当使用电机时,电机会转动链轮和轮毂组件。 轮毂组件将旋转力从电机传递到凸轮轴。
