It’s hard to imagine production machinery without having a set of gears in it. A gear is a basic mechanical element for speed or torque management. This is also a fact that even today, designers and manufacturers are constantly working to improve the gear design and manufacturing process to produce the best set of gears for various applications throughout the airline, marine applications, earth moving equipment, and machine tool industries.
Gear design started way back right from the Renaissance time and it is still going on today. At this point in time, several types of gears and gear arrangements have been used in machine design. The author has also been associated with several such gearbox designs using spur, helical, bevel, and worm gears throughout his professional career over fifty years. The course will reflect some of those experiences to help future designers design helical gears.
The author, during his time, has collaborated with several gear manufacturers such as Philadelphia Gear Corporation, Arrow Gear Corporations, etc. to name a few. The contents of this course are very much guided by the inputs received from these two companies with comments from the author.
This course focuses on helical gear design principles and applications for the machine tool industries and automobile applications. The course contains force analysis, durability analysis, and noise reduction for gear applications.
The principles of gear nomenclature and manufacturing will be covered in brief since designers are not required to know that since gear manufacturers will help the designers to that extent. Simple shortcut formulas for designing gears of various types will be demonstrated in this course. The course will also demonstrate the methods and processes that the author used to design gears and gearboxes for machine tool applications only.
For various applications, durability, and strength horsepower of helical gear sets, noise reduction, etc., are very pertinent requirements that designers have to satisfy. Helical gear design principles will be explained very briefly for a typical torque reducer that the author has applied in the indexing unit of a CNC turning center.
Many of the contributors are very well-known in the gear industry, such as Darle Dudley, Elliott Buckingham, Gene Shipley, Prof. M F Spotts, and many others. The contents should help designers to a great extent in applying the design principles for their design efforts.
Details of gear classifications as per the American Gear Manufacturers Association (AGMA) will be briefly explained. In general, it is important for designers to know the design approach and design process for gears for machine tools and marine and automobile applications where durability, cost, and noise reduction are very important design considerations. Applications, examples and design discussions will be limited to helical gears that are mostly applied in machine tool applications. For applications such as heavy earth moving equipment, ship engines, automobile transmission, etc., helical gears are found to be very suitable and cost-effective.
