Sankyo的Do系列环形分度器具有大型固定中心孔的铸铁外壳。中心和外圈可以支持刻度盘上方或下方的固定刻度盘。由于内圈和外圈都是相同的外壳,刚性得以维持。薄的外壳使一个小的占地面积,并设计为一个旋转装配机的基础。带有其他外围设备的机器人很容易安装到这个多功能单元上。弧面凸轮旋转三共制成针轴承式凸轮从动件。优化凸轮从动件直径本质上最大限度地扭矩传递和延长寿命小时,由于更少的旋转与增加的表面接触。分度增量停止范围从16到60,以支持从2250到7200毫米(7.3到23.5英尺)的大直径表盘。这为每个组件之间的检查站提供了足够的空间。多个指数周期提供连续或按需占空比,在停留期间,指数环锁定在20至30弧秒内。 These versatile units index in both directions or oscillate. The Ro Series can perform non-patterned motions with a continuous lead cam using servo driven motor or provide incremental stops less than 16. Most units are driven with geared motors that are within the height of the index unit housing or Sankyo's R series worm reducer as shown. Timing cam packages are available with inexpensive photo beam sensors or proximity switches for wash down (IP67/NEMA-6/6P) applications.
