Rotary Indexer for Indexing Motion

Indexing is the process of intermittent motion where machine starts and stops at precise locations in specified intervals. Indexing motion is required in most machines for many applications since the stopping period (dwell period) of indexing allows other units in the machine do their jobs.

In post [ Rotary Indexer For Indexing Motion], we explained the meaning of indexing with the example of displacement and velocity diagram to give an idea how the indexing mechanism works. We also showed the location of input and output shafts of the rotary indexer.

Moment of inertia

The Moment of Inertia or Mass Moment of Inertia is the measure of a body's resistance to change in it's rotational speed. The moment of inertia must be specified with respect to a chosen rotational axis. The moment of inertia depends on the body's mass distribution and the rotational axis chosen.

Differential screw | Ezy Mechanic

A differential screw can be made using standard screw threads with different pitches. It can achieve small and precise movement from the pitch differences. In this video, we use 2 metric coarse thread screws to get motion of 0.25 mm per 1 turn.
