COURSE NO: M04-031
Principles and Use of Gears, Shafts and Bearings
Course Highlights

This online engineering PDH course takes the student through the various steps needed to gain valuable insight into the subject matter. The steps include design, types, material/manufacture, load and stress analysis, sample problems, and sketches of actual industrial applications with expert analysis. It is written in an easily understood manner with many illustrative images. The information provided will encourage individuals to make innovative improvements within their field of expertise.


Gears, shafts and bearings are the backbone of equipment used in the field of Mechanical Power Transmission. They are the primary components in such things as transmissions, drive trains, and gear boxes. Transmissions and drive trains deliver power from the engine to a variety of vehicles ranging from automobiles to earth moving equipment. Gear boxes of a variety of sizes and shapes power the many machines and equipment found in our factories and in our homes.


This 4 PDH online course is intended for mechanical engineers, automotive engineers, plant engineers, industrial engineers, and any other discipline with an interest in Mechanical Power Transmission.
