TRUNNION DRIVES

The E/ET series of standard index drives are based on a precision barrel cam mechanism design which provides excellent positioning accuracy and refined motion profiles to ensure smooth progress between stations. Standard mechanism designs provide a choice of 2 to 24 stations.

This range of drives is similar in concept to the standard range of indexers with modified housings to facilitate mounting with the output turret horizontal. These systems can be used for rotating horizontal axis applications usually associated with robotic welding and positioning cells. The indexer bearing assembly usually has sufficient load bearing capacity to support one end of the trunnion assembly.

The drive systems adopted for these units is usually the C-flange worm geared motor type which offers the most compact design. Larger units incorporate a worm gear mechanism built into the housing which is belt driven from an externally mounted brake motor. This method offers convenient access to refine index times by changing the belt pulley ratios.

All units have a heavy duty output table supported on a quality bearing matched specially to Expert requirements. A central access hole enables services to be routed conveniently to the table top.

Mechanical or Inductive switch arrangements can be supplied on request fitted to the indexer to give appropriate signals for position and direction.
