Globoidal cam indexer - max. 200 c/min | AD series
Design Features
Sankyo's AD/Alpha 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.
Why Sankyo
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 30 arc seconds during the dwell period.

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.
Rotary indexer / cam - 3 430 - 8 330 Nm, max. 200 rpm | DTR series
The large dial index DTR series has the same internal components as the DT series but includes an innovative integrated reducer that allows the motor to be mounted on the right, left or with 2 motors (as shown). The internal reducer is a low backlash worm type compatible with high torque motors. Dual flange motors can mount directly to the index housing to increase the horsepower but still keep a...
Rotary indexer / cam - 3 430 - 8 330 Nm, max. 200 rpm | DTR series
The large dial index DTR series has the same internal components as the DT series but includes an innovative integrated reducer that allows the motor to be mounted on the right, left or with 2 motors (as shown). The internal reducer is a low backlash worm type compatible with high torque motors. Dual flange motors can mount directly to the index housing to increase the horsepower but still keep a small footprint. The input shaft is free to drive other peripheral equipment to stay synchronized with the indexing dial. The input can also drive our patented cam balancer (shown left) to offset the output load torque causing the motor torque requirement to be much less. Horsepower that was used to rotate the output load can be partially redirected to increasing the acceleration or decrease the deceleration. Fast index times can be achieved with small motor torque requirements. Large loads can be rotated with a less expensive smaller housing size to minimize the footprint.
An inherent problem of rotating large indexing dials is waiting for the dial to settle or become motionless. The overall machine throughput will increase because the work done on the dial can be started sooner. Since the cam balancer torque compensation is adjusted with air pressure, fluctuating output loads can be accommodated with a turn of the air regulator. Air consumption is minimal, its equivalent of filling an air cylinder reservoir but not cycling it, its only uses air if the regulator is adjusted. Output backlash is minimized to reduce vibration which enhances the life and accuracy of the unit. Based on the advantages of the cam balancer, justifying this option is simple.

These versatile units index in both directions or oscillate by reversing the motor. Most units are driven with geared motors that are within the height of the index unit housing. There is no need for spacers or burning a hole in the mounting plate to accommodate for drive height interference. An optional TF series torque limiter safety clutch mounts between the index and indexing dial plate or a TC series acts a coupler for shaft to shaft applications. Torque thresholds are easily adjusted without any disassembly and a proximity sensor detects overloads.
