Module 1 - DRIVE SYSTEMS
Now avalaible on CD-ROM
SYNOPSIS
This module considers drive systems in relation to the characteristics of the driving and driven machinery. It examines the available options for torque and speed transformation, that is belts, chains, gears, and electric and hydraulic drives, and evaluates these for both constant and variable ratio drives.
