High-speed Free-position Indexing

Benefits	High-speed, precise positioning.
Model	RollerDrive
Description	The zero-backlash RollerDrive is driven by a servomotor for high-speed operation with accurate positioning performance. It has no play, which gives it excellent dynamic characteristics for smooth, undisturbed motion. Short settling times.

Oscillating and Rotating Arm

Benefits	Precise motion, improved settling time.
Model	RollerDrive
Description	The zero-backlash, or play-free, RollerDrive drives robot arms and other masses with precise motion characteristics. Zero-backlash means there is no play in the mechanism. This ensures smooth and undisturbed motions under repeated forward/reverse changes or changes in the direction of loading, such as the line of gravity.

Large-size Substrate Turning

Benefits	Improved settling time, easy to integrate.
Model	RollerDrive
Description	The zero-backlash RollerDrive has no play so it can turn large substrates smoothly without motion disturbances. This allows for shorter positioning times. It is also designed to bear heavy thrust loads, so you can mount fixtures directly.

Supply and Discharge Welding Materials

Benefits	Easy to integrate, high-speed operation.
Model	Indexing Drive
Description	This application uses simple ON/OFF control of the general-purpose motor to position heavy, over-sized objects quickly and accurately. It holds position without clamping, requiring no hydraulic equipment, or extra tooling. It also offers shorter positioning time. The all-in-one α Series comes with an integrated drive unit.

Synchronized Pick & Place and Dial

Benefits	Mechanically synchronized for reliable, high-speed operation.
Model	Indexing Drive Oscillating Handler
Description	An indexing drive is used to index this dial. The Oscillating Handler used to feed parts in this example is mechanically synchronized with the input shaft of the indexing drive. All motions are mechanically linked to ensure reliable operation at high speed.

2.5-stop Indexing Dial

Benefits	Tight integration of work stations with separately located loading and unloading stations.
Model	Indexing Drive Oscillating Handler
Description	This special order 2.5-stop indexing drive indexes the dial every 144°. This allows the work stations to be arranged in the following order: loading, station 4, 2, unloading, 3. This configuration allows the loading and unloading stations to be located separately.

Synchronized Operation off Single Driveshaft

Benefits	Easy to integrate, high-speed operation.
Model	Indexing Drive
Description	In this application, multiple Indexing Drives are mechanically driven off a single jackshaft. Mechanical synchronization eliminates the need for sensor-based sequential motion control, and allows for a simpler design.

Workpiece Inversion

Benefits	Inline inversion of workpieces on a conveyor.
Model	Indexing Drive
Description	In this example, the conveyor is mounted between the two dials on the output of the Indexing Drive. The conveyor leads the workpiece into the notches in the dials, and the indexer turns the dials to invert the workpiece. The inversion is accomplished inline with the conveyor.

Large-scale Fixture Turning

Benefits	Adds support for multiple product models.
Model	Indexing Drive
Description	The indexing motion of the Indexing Drive turns a multi-sided fixture via a set of gears. Each surface can have a different fixture to allow work on multiple product models.

Coil Winding

Benefits	Winds coils evenly at high speed.
Model	Oscillating Drive
Description	An Oscillating Drive is used to move the wire dispensing nozzle back and forth along a spinning mandrel, which winds the wire into a coil. The smooth motion of the Oscillating Drive produces an evenly wound coil.

Glass Edge Polishing

Benefits	Precise positioning, unaffected by work loads.
Model	RollerDrive
Description	This application indexes the glass substrate for edge polishing. The zero-backlash mechanism has no play, which keeps the output rigid, even under work loads. The right-angle input and output shafts minimize the footprint into a low-profile unit.

Motor Core Staggering and Lamination

Benefits	Staggers at any angle for precision laminations.
Model	RollerDrive
Description	The RollerDrive can be indexed to any position for staggering and laminating motor cores. The cores can be laminated to any preset angle, depending on the produt.

Center Column Indexing Drive

Benefits	Simplifies the design of rotary assembly machines.
Model	Indexing Drive Oscillating Handler Parts Handler
Description	The DA Series has three coaxial output shafts for intermittent, stationary, and continuous motions. It serves as the chassis for rotary process machinery. All outputs are synchronized to the input shaft. The Parts Handlers on the upper dial are driven by the continuous output shaft for synchronized operation with the rest of the process.

Central-mounted Work Units

Benefits	Integrates rotary dial and working units into a small footprint.
Model	Indexing Drive Parts Handler
Description	The zero-backlash, or play-free, RollerDrive drives robot arms and other masses with precise motion characteristics. The absence of play ensures smooth and undisturbed motions under repeated forward/reverse changes, and changes in the direction of loading, such as the line of gravity.

Work Unit Mounted using Hollow Center Shaft

Benefits	Provides space for mounting work units.
Model	Indexing Drive
Description	A pillar can be mounted inside the hollow center of the output shaft for mounting overhead work units.

Broach Drive in a Turning Center

Benefits	Thin-profile, powerful continuous rotation.
Model	RollerDrive
Description	The continuous rotation of the RollerDrive is used to drive the broaching tool. The right-angle input and output shafts form a low-profile unit with a small footprint.
