Rotary Motion/Cam Index Drives/

  • Product Details
  • Inquiry

Cam index drives are precision mechanical systems that generate intermittent rotary motion through a cam and follower mechanism. A continuously rotating input shaft drives a profiled cam, which controls the motion of followers to produce fixed angular output increments. This cam index drive is a type of motion control device used to convert continuous rotary motion into precise, intermittent motion

Technical Guide to TallMan Robotics DF Cam Index Drive

DF cam index drive uses a barrel cam to convert continuous input rotation into intermittent output motion. The cam engages a set of needle roller followers mounted on a turret. The cam profile determines the index angle, dwell period, and acceleration curve. A hardened ground cam surface runs against the followers. The output shaft holds the turret.

FAQs about DF Cam Index Drive

What is a cam index drive?

A cam index drive controls step rotation. It uses a cam mechanism. It ensures precise angular positioning.

What does a cam index drive do?

It changes steady motor rotation into a start-stop motion. The output shaft indexes and then pauses. The cam controls the entire motion.

Can I change the index angle after purchase?

No. The cam profile determines the angle. You must order a new cam and turret assembly. The housing remains the same.

How do I adjust follower preload?

Remove the turret from the housing. Add or remove shims behind each follower stud. Target drag torque is 0.5 Nm when turning the turret by hand.

What happens if the cam surface spalls?

The followers will skip. The output will lose position. Stop the drive immediately. Send the cam for regrinding. Replace all followers at the same time.
