Indexing Units

Indexing Units

Mechanical indexing units or oscillating mechanisms with globoidal or flat cams are used everywhere with repeating motions. Once the motion profile is decided and manufactured it cannot be changed unless the indexing mechanism is exchanged. An exception is the servo-driven indexing unit with a backlash-free, constant velocity globoidal cam mechanism.

The size of the indexing unit is determined by analysing the forces resulting from the load, velocity and the acceleration/deceleration forces. INMARA has many years experience in the selection of the optimum indexer size and can therefore serve its customers in the best possible way. Mechanical indexing units and indexing drives with globoidal cams or flat cams have a high reliability and virtually zero maintenance during a long service life. Depending on the application there may be need for protecting the indexer/oscillator from overload on either the input or the output side of the indexer. Overload clutches are available to protect the indexing drive unit in emergency situations (failure in the power supply, blockage through external influences, interfering motions).

Further INMARA delivers indexing units complete with motor and gear units of any type selected by the customer.

Indexing drives are used in many areas of machine design.
