7、件2，使铜料下落的是执行构件3，使铝料下落的是执行构件4，四个执行构件的运动协调关系如图所示。下图1中T1为执行构件1的工作周期，T2是执行构件2的工作周期，T3是执行构件3的工作周期，T3是执行构件3的动作周期，T4是执行构件4的动作周期。可以看出，执行构件1做连续圆周运动，执行构件2、执行构件3、执行构件4都做间歇往复移动。4个执行构件的工作周期关系为：T1=T2=T3=T4。工作周期T1执行机构运动情况执行构件1运动执行构件2关闭开启执行构件3关闭开启182哈尔滨工业大学课程设计说明书执行构件4关闭开启T

8、1=T2=T3=T4运动循环图2.2运动功能分析及运动功能系统图为保证系统过载时不至于损坏，在电动机和传动系统之间加一个过载保护环节。过载保护运动功能单元可采用带传动实现，这样，该运动功能单元不仅具有过载保护能力，还具有减速功能，如图3所示。其中带传动的传动比。图3过载保护运动功能单元根据前面的分析可知，驱动执行构件1工作的执行机构应该具有运动功能如图4所示。该运动功能把电机单向转动转
