From MISUMI USA

The tutorial explanations to this point have been centered around usage points on mechanisms and machine element components. From this point forward, mechanism designs on 1. LCA that can operate at higher speeds, and 2. LCA that can repetitively operate programmed movements over long time durations will be explained.

Linear Actuators
Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly. The actuator's load is attached to the end of a screw or rod and is often unsupported.

Three fundamental elements of LCA, the Mechanism, the Actuator, and the Controller are explained in this section. Firstly, definitions of the three elements are discussed.

An LCA element "Mechanical cam/link mechanism" appeared as schemes to repeatedly produce mass quantities of goods (Ford-ism) developed. This was an advancement from the first generation LCA elements...

Let us take a look at the aspect of LCA designs in regard to "Wide Variety Small Volume" production lines.

Sensor usages for motion mechanism designs will be explained based on an application example diagram.
