Function
The drive (2) drives the indexing ring / output flange (1) via the input shaft (3) through the drum cam. The output plane
is offset by 90° to the drive plane. A uniform radial motion is converted on the input side into a clocked or uniformly
reduced output motion. The superstructures are mounted on the indexing ring / output flange (1). The position
indicator (4) shows the respective position of the drum cam. The type plate is attached to the housing (5). If required,
additional superstructures can be fastened to the non-rotating centre section (6).
An additional locking of the indexing ring / output flange is not necessary. It can lead to mechanical
overdetermination and thus in the long term to destruction of the rotary indexer. The power flow is either from a
three-phase motor (with / without brake) via a reduction gear or from a chain wheel or belt wheel to the input shaft
of the rotary indexer. This is permanently connected to the drum cam without any further internal gear stages and
rotates the indexing ring / output flange via drum cams. The indexing ring is mounted rigidly and clearance-free in a
wire bearing assembly (in steel rings not directly in cast iron). Shaft sealing rings corresponding to the respective size
seal the rotary indexer internally and externally.
