A mechanical tool for exact indexing movement realization is the Swing Roller Gear Index Table. Its main parts are basic ones including a swing mechanism, roller gears and indexing table. The fine meshing between the roller gears and the indexing table allows the table to revolve precisely depending on a specified angle of indexing; the oscillation mechanism causes the roller gears to oscillate back and forth through a designated driving technique. This unusual structural architecture distinguishes it in many industrial environments needing exact positioning and indexing.

An clever mix of oscillating motion and gear transmission forms the basis of the operating concept. The oscillating mechanism forces the roller gears to oscillate regularly when an outside power source drives it. The roller gear interacts with the tooth grooves on the indexing table throughout the swinging operation; each swing pushes the indexing table ahead by a defined angle, therefore accomplishing the indexing function. Higher stability and precision this approach offers than other indexing techniques.

The basis of its construction is the unique design that achieves the oscillating motion. Usually it comprises of a cam and a swinging output mechanism; the profile curve of which is especially intended to push the output portion to conduct reciprocating motion. This design lets the output swing back and forth inside a specified angle instead of just turning.

Indexer of cylindrical cam: The major gearbox element is cylindrical cam; the curved grooves on the cam surface interact with the roller follower. Usually cylindrical in form, the cylindrical cam is realised by the follower along the curved groove in the circumferential direction of the cam, therefore realising the indexing motion structurally. The general framework is small and appropriate for high-speed, high-precision indexing situations.

Mostly positioned on the turntable, flat plate cam indexer consists of flat plates cam and roller. The plane curve of the flat cam distributes the curve profile; the roller drives the turntable to execute intermittent indexing motion using the plane curve of the cam. Its construction is really straightforward and understandable; installation and maintenance are also uncomplicated.

This form of motion is appropriate for the working scenes that demand periodic swing action, like some material dumping and swing gearbox; the output end does reciprocating swing in a particular angle range. For the filling process in the food packaging sector, it is utilised, for instance, to swing the material from one point to another.

Realised is a rotational indexing motion in constant speed. Driven by the follower according to a specified angle of intermittent indexing rotation, the movement process is rather smooth, high indexing accuracy, applicable to the need for high-precision rotary positioning circumstances, such multi-position machining equipment in the positioning of the turntable.

It likewise realises rotational motion and intermittent indexing, however unlike the cylindrical cam indexer, its motion path is carried out in the plane. Its motion fits some of the more limited space requirements, and the demand for in-plane indexing-often employed in the paper conveyor positioning-occurs extensively.
