在自动和半自动的机器中,常遇见这种情况:必须周期地把某动作完全停止。然后将运动传给机构的从动构件,这就得使用从动构件具有间歇运动的机构,为改善工作条件,提高机械效率,人们常希望间歇机构静止时间与运动时间有不同比例。本文介绍一种具有上述功能的新型组台槽轮机构。一、结构及原理为解释和计算的方便,采用带两个滚销的主动盘和四槽槽轮组成的槽轮机构(见图1),这种机构静止时间和运动时间相等。图2即组合槽轮,它是将两个图1所示的槽轮机
In automatic and semi-automatic machines, it is often the case that an action must be stopped completely and periodically. The movement is then passed to the driven member of the mechanism, which requires the use of a mechanism with intermittent movement of the driven member. In order to improve working conditions and improve mechanical efficiency, it is often desirable to have a different ratio of the resting time to the exercise time of the intermittent mechanism. This article describes a new group of Taiwan sheave mechanism with the above functions. First, the structure and principle To explain and calculate the convenience, the use of two-pin with the active disk and four-slot sheave pulley mechanism (see Figure 1), this mechanism is still the same time and exercise time. Figure 2 is a combination sheave, which is two will be shown in Figure 1 sheave machine
