Rotary indexer / for heavy loads - 61.7 - 1 960 Nm, max. 200 rpm | DT/RT series
Sankyo's DT/RT series features a low profile design cast iron housing with a ground pilot flange for mounting dial plates, hub less gears, or weldment fixtures. Above the indexing dial, a second dial mounting surface is stationary and hollow to allow air lines, wiring or bearings for a shaft to be routed through the tolerance bore. 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. Our DT series offers multiple index periods to run continuous mode or 'on demand' duty cycles with the indexing flange locking in position within 30 arc seconds during each dwell period. 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 or oscillate by reversing the motor using a VFD (variable frequency drive) controller.
