Gear drives are the base components and the lifeline in many mechanical transmission and processing operations. With today's emphasis on reliability and operating efficiency, the selection of the proper drive has become increasingly important. The right choice can result in a big difference in productivity, operating costs, and energy savings. Selecting the right gear drive ideally brings together the gear manufacturer, the system designer, and the end user. At the outset, a gear manufacturer must know what the drive will be used for, the demands to be placed upon it, and the nature of the equipment it will be driving.
This 5 hr course presents a technical coverage of gear fundamentals. It is intended as a broad overview written in a manner that is easy to follow and to understand by anyone interested in knowing how gear systems function. Since gearing involves specialty components, it is expected that many engineers may not have been exposed to every aspect of this subject. However, it is essential to have a minimum understanding of gear basics and a reference source for details in order to properly select gear components and design gear systems.
This course is applicable to engineers of all disciplines. No specific prerequisite training or experience is required. The course provides a good introduction to gear systems for engineers not familiar with the subject, and serves as an excellent design reference and resource for engineers who have some experience in design and selection of gear systems.
