PU Parallel Cam Indexers are mechanical Indexing Cam Gears used to convert continuous rotary motion into precise, intermittent motion, commonly used in automation and manufacturing processes. 

The term “parallel” refers to the design of the cam mechanism of Indexing Cam Gears, where the cam profiles are arranged in parallel to achieve smooth and accurate indexing, defining types of PU Parallel Cam Indexing Gears. Parallel Cam Gears are used in automation and manufacturing to convert continuous rotary motion into precise, intermittent motion.

Engineering Perspective on TallMan Robotics PU Parallel Cam Indexers

PU parallel cam indexer uses two face cams mounted on a common input shaft.Cams act on two separate output turrets.Each turret has its own set of needle roller followers.Cams share the same housing.

FAQs about PU Parallel Cam Indexers

What is a PU parallel cam indexer?

A PU parallel cam indexer provides step rotation. It uses a parallel cam mechanism. It ensures precise angular positioning.

How does a parallel cam indexer work?

A motor rotates the input shaft. The cam guides followers. The system creates indexing and dwell phases.

How do PU cam indexers compare to other types?

They use a parallel cam layout. This design improves compactness. It supports efficient integration.

What does a PU parallel cam indexer do?

It drives two output shafts from one input. Both outputs index at the same time or with a fixed angle offset. One housing contains all parts.

How do the two cams stay in sync?

One input shaft passes through both cams. A keyway locks each cam to the shaft. The shaft guarantees zero phase drift between outputs.

Can I adjust the phase between outputs?

Yes. Loosen the cam clamp on one output. Rotate the output turret to the new position. Tighten the clamp to 80 Nm. Recheck with a dial indicator.

What happens if one output jams?

The common input shaft stops completely. Both outputs stop. A shear pin or torque limiter on the input shaft protects both cams. Replace the pin before restarting.

Can I run only one output while the other dwells?

No. Both outputs index together. The input shaft drives both cams simultaneously. You cannot disengage one output without removing the cam.
