转速差在机械设计中应用很广,现举三个实例:一、自驱式机械动力头这种机械动力头与一般机械动力头相比,在结构上比较简单,具有一般动力头的动作循环。它的结构如图1所示。动力由法兰电动机输入。在空心轴Ⅰ上装有电磁离合器②的外摩擦片壳体及齿轮③。当离合器②通电闭合时,动力由空心轴Ⅰ经离合器②直接传给动力头输出轴Ⅳ。该轴转速与电动机转速相同。与此同时,电动
Speed difference in the mechanical design is widely used, give an example of three: First, self-propelled mechanical power head This mechanical power head compared with the general mechanical power head, the structure is relatively simple, with the general power head action cycle . Its structure as shown in Figure 1. Power input from the flange motor. On the hollow shaft I equipped with electromagnetic clutch ② outer friction plate housing and gear ③. When the clutch ② energized closed, the power from the hollow shaft I by the clutch ② directly to the power output shaft Ⅳ. The shaft speed is the same as the motor speed. At the same time, electric
