What is a cam gear? What is an indexer?

HEINZ cam gears transform a uniform rotational movement into an intermittent output movement. Say, the constant rotation of the input shaft is converted into a clocking stepping motion. This finds an application in automatic assembly machines, for example, to clock and precisely position a product through several assembly steps.
This is also the reason why these cam gears are often called step gears / indexers.

The use of a HEINZ cam gear offers you the following advantages:

  • High step frequency, possible are up to 2000 cycles per min.
  • Gentle starting and braking due to positively controlled movement through the cam.
  • Positive positioning, no additional positioning unit required.
  • Constant movement time, the overlapping of movement processes is possible without loss of time.
  • Very high reliability; runs for several years without interference.
  • HEINZ cam gears work in both directions of rotation and can also be used reversing.
  • Due to the backlash-free design of the HEINZ cam gears a very high accuracy will be achieved.

The use of a HEINZ cam gear is particularly important in applications with a high demand for exact and identical repetitive step movements such as, for example, in packaging machines, automatic assembly machines, press automation and handling equipment.
