PARALLEL SHAFT INDEX DRIVES

Conjugate Cam or parallel shaft index drives are the most suitable systems for ultra high speed indexing. Up to 1000 indexes per minute are feasible. The inherent design of these mechanisms eliminate reversal of roller follower direction, present in other designs during the indexing sequence, thus removing any tendency for overheating and subsequent unwanted wear of cam surfaces.

Parallel shaft units are not suitable for high numbers of stations. One-station units are feasible with a maximum of eight. Six and eight station units incorporate a type two-mechanism design which provides two indexes and two dwells for each input shaft rotation. Hence for a given index rate the input shaft of type two units should be driven at half speed.

Various standard cam designs are available offering different ratios of motion to dwell for one complete input shaft rotation. Specials and Oscillating Mechanisms can be engineered to suit specific requirements.

All units in this range can be supplied fitted with a geared motor assembly suitable for index on demand applications or continuous running. Optional motor specifications to suit customers' requirements can be specified.

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