What is an indexer / cam gear?
Cam gears convert a continuous rotational movement into an intermittent output movement. This means that the constant rotation of the input shaft is transformed into a step-by-step motion. This technique is used in applications such as assembly machines to precisely index and position products through multiple assembly steps. Consequently, cam gears are often referred to as indexers.
Application for Cam Gears – Advantages
- High indexing frequency, with a performance of up to 2,000 cycles per minute is possible.
- Smooth start and stop thanks to the positively controlled motion sequence of the cam.
- Form-fit positioning without the need for an additional positioning unit.
- Precise positioning allows for the overlapping of motion sequences without any time loss.
- Highest reliability over many years without interruptions.
- Cam gears operate in both rotational directions and can be used in reversing applications.
- Thanks to the backlash-free design of the cam gears, exceptionally high accuracy is achieved.
Typical applications for stepper gears require precise and repeatable step movements, especially in areas such as packaging machines, assembly systems, press automation, and handling equipment.
Here is an example of the positively controlled combination of multiple cam gears and indexers:
A product is sorted and fed into an assembly process. The assembly takes place on the central rotary table, which indexes the products through the assembly process while simultaneously serving as a stable and reliable foundation. The finished assembled products can also be sorted and discharged.
