Rotary Motion/Cam Index Drives/

  • Product Details
  • Inquiry

Table cam indexers are precision rotary positioning devices that use a cam and follower mechanism to generate intermittent motion with fixed angular increments. A continuously rotating input shaft drives a profiled cam, which guides followers to index a circular table mounted on the output. Table cam indexers provide precise rotational positioning of a table or platform, often in conjunction with a cam mechanism to ensure smooth and accurate indexing.

Detailed Overview of TallMan Robotics DT Table Cam Indexers

This table cam indexer integrates a cam mechanism with a large diameter output table. The table replaces a separate flange or shaft. A precision crossed roller bearing supports the table directly. The bearing handles high moment and axial loads. A barrel cam or conjugate cam sits inside the housing below the table. Needle roller followers engage the cam groove. The table surface has tapped holes and a pilot bore for tooling alignment. An oil bath lubricates all internal components. The housing mounts from the bottom. A seal ring prevents oil leakage at the table perimeter.

FAQs about Table Cam Indexers

What does a table cam indexer do?

It rotates a large dial plate directly. The table is part of the indexer. You bolt your tooling to the table surface. No separate flange or shaft is needed.

How does the crossed roller bearing help?

The bearing supports heavy tooling without tilting. Standard bearings would tilt under off-center loads. The crossed roller design resists moment loads from large dials.

How do I prevent oil leakage around the table?

The table has a labyrinth seal at the perimeter. Replace the seal ring every 5000 hours. The seal allows table rotation without rubber contact. Do not use compressed air near the seal gap.

How do I measure table flatness?

Place a dial indicator on a fixed stand. Touch the tip to the table surface. Rotate the table through a full index. Maximum flatness deviation is 0.05 mm across the entire table.
