间歇渐开线机构是应用较早的步进机构之一。其主动轮(不完全齿轮)连续转动,带动从动轮(普通齿轮)断续转动,从而将连续转动转变为间歇运动。与其它步进机构相比(如槽轮机构)它具有易于制造、构造简单、运动时间与静止(停歇)时间的比值不受机构结构的限制,工位数可任意配置等一系列优点。因此,尽管这种步进机构运转时有。起始啮合冲击现象,以及在机构参数选择不当时会产生齿顶干涉现象,但仍在许多轻工机械以及变速机构、记数机构中获得应用。
The intermittent involute mechanism is one of the earlier stepper mechanisms. The driving wheel (incomplete gear) continuous rotation, driven by driven wheel (ordinary gear) intermittent rotation, which will be continuous rotation into intermittent movement. Compared with other stepping mechanism (such as sheave mechanism) it has a series of advantages of easy to manufacture, simple structure, exercise time and rest (rest) time ratio is not limited by the structure of the organization, the number of stations can be arbitrarily configured. So while this type of stepping mechanism is in operation. Initial meshing impact phenomenon, as well as in the choice of mechanism parameters will produce interference phenomenon addendum, but still in many light-duty machinery and variable speed mechanism, the number of institutions obtained.
