MILL 133 - Power Transmission Systems


3 Credits
This course will provide an overview of mechanical power transmission systems and identifies the industries that use them. It also explains several safety issues associated with working on, repairing, and maintaining mechanical power transmission systems. The course will define types of shafts and how there components are attached using keys and keyways. Friction and anti-friction bearings their components, characteristics, and applications are explained, as are the factors that affect bearing life. It also includes step-by-step instructions for how to safely remove, inspect, and install bearings and bushings. Various types of coupling, sprockets, chains, belts and pulleys will be discussed along with removal, installation, alignment and methods used to calculate and adjust system speeds. Gear and gearbox terminology is discussed as well as gear parts, dimensions, tests used to evaluate, inspect and rebuild gearboxes. Participants learn the installation, maintenance, removal, and lubrication requirements of all the components of mechanical power transmission systems.
