Sankyo's DF Series features a low profile design cast iron housing with a ground pilot flange for mounting dial plates, hub less gears, or weldment fixtures. A globoidal cam rotates Sankyo made needle bearing type cam followers. Optimizing the cam follower diameter inherently maximizes torque transfer and extends the life hours due to fewer rotations with increased surface contact. Multiple index periods offer continuous or on demand duty cycles with the indexing flange locking in position within 60 to 20 arc seconds during the dwell period (depending on the housing size). The output flange turret is mounted with top and bottom tapered bearings which supports large bending moments, maintain rigidity and reliability.
These versatile units index in both directions, oscillate or perform non-patterned motions with a continuous lead cam using servo driven motors. Most units are driven with geared motors that are within the height of the index unit housing or Sankyo's R series low backlash worm drive reducer. The output can be customized with dual output flanges to mount dial plates on both sides of the index or hollow to transfer air. Timing cam packages are offered with inexpensive photo beam sensors or proximity switches for wash down (IP67/NEMA-6/6P) applications.
