Early in the s, Professor Shigley called Professor Mischke and said, "I've .. J. E.

He said that Shigleys book a precursor to this Handbook had been his primary source of information about worm drives, and a wealth of other machine design information.
As it turned out, the resulting design worked as required.
It not only pleased our Alaskan customer but became a standard on all antenna systems. I did not get a promotion as a result of the success of this new design, nor did I receive a raise. However, I was proud, and, as you can surmise, still am. I credit this successful design evolution to the material on worm drives in Shigleys book. And there is more to this story. The worm drive gearbox we ultimately downloadd contained a plastic drive element.
This allowed the backlash to be greater than what could be tolerated in positioning accuracy and did not provide the necessary strength to break the feed horn loose from a covering of ice. The original manufacturer of the gearbox refused to change this drive element to metal for the units we would be downloading.
If we made the change ourselves, they said, the warranty would be voided. However, after absorbing the wealth of information on worm drives in Shigleys book, I felt confident that we could make this substitution without endangering the reliability of the unit. Also, because of Joseph Shigleys reputation in the mechanical engineering community and the extensive list of references he cited, I never felt the need to consult other sources.
Another aspect of this story is also important to note. In addition to the information on worm drives, I also used Shigleys book to find comprehensive design information on the many other machine elements in the new design: gear train geometry, chain drives, couplings, roller bearings, bolted joints, welds, lubrication, corrosion, and the necessary stress and deformation calculations I needed to make.
Now in its Third Edition, this Handbook includes the information machine design engineers have come to trust.
We hope you will find this information invaluable as you constantly strive to improve your designs, whether by your own initiatives, or for other reasons. Each section focuses on a distinct collection of related material.
For example, Part 3, Gearing, contains chapters on spur gears, helical gears, bevel and hypoid gears, worm gearing, and power screws. However, each chapter stands on its own, providing direct access to a specific area of interest or need. This Handbook is a unique reference, capturing the breadth and depth of what is currently known about each of these design element topics. The nine sections are Part 1.
Machine Elements in Motion Part 2. Gearing Part 4. Power Transmission Part 5. Fastening, Joining, and Connecting Part 7. Load Capability Considerations Part 8.
Performance of Engineering Materials Part 9. Classical Stress and Deformation Analysis While there are many ways the nine sections could have been ordered, the order chosen for this Third Edition provides one sequence of steps to the evolutionary design process.
For example, you might first consider the kinds of motions you need and how they might be accomplished. Part 1 might help you choose a classic mechanism or linkage, a cam, or maybe some arrangement of gears. Possibly your design needs to absorb or store energy, so the chapters included in Part 2 would provide the information you need. Depending on your design, Parts 3 and 4 cover virtually every type of gear set, drive type, coupling, and the common elements related to these devices.
Part 5 covers how rotating elements might be supported, typically with either roller- or journal-type bearings. And if bearings are present, then lubrication and seals must be carefully considered. Part 6 continues the design process to the consideration of how components will be assembled. Are there structural bolts, or just mechanical fasteners, or are parts to be welded?
The coauthor of the chapter on welding is the well-known author of the preeminent book on welding, so this Handbook should provide all the information you need relative to this topic. The last chapter in this section presents the complex procedure necessary to maintain proper fits and tolerances, a full-time job in itself for some engineers.
Everything an engineer needs to know about this area of manufacturing can be found in this Third Edition of the Handbook.
At some point, loads will be determined, both statically and dynamically; therefore, Part 7 contains the information you need to make decisions relative to the reliability of critical parts. Information on vibration, and just as important, its control, is provided in a chapter in this section. The selection of materials is covered in Part 8 and includes chapters on wear and corrosion.
With regard to the problems of corrosion, one of the main components of a system I was responsible for failed due to excessive galvanic corrosion. The information contained in this Handbook helped me not make that mistake again. The last section, Part 9, contains the classic information on stress and deformation calculations every mechanical engineer learns in school, but finds escapes exponentially if not used regularly.
Here, four chapters provide every important calculation practicing engineers should need, and they are introduced in a manner that can be understood and used with confidence. In addition to grouping the chapters into nine sections, almost a dozen of the 50 chapters in the Second Edition, which contained a variety of information ancillary to the machine design process, have been removed.
Therefore, the scope of this edition of the Handbook is focused on the more traditional machine design topics. For those familiar with the previous editions, one chapter that was in the First Edition but not in the Second, Pressure Cylinders, has been included in the Third.
Discovering opportunities to improve or evolve your designs successfully is one of the primary ways we expect you to use this Handbook.
Each chapter has considerable design information and the format used is unique.
What follows is a discussion of just some of the helpful information you will find in each chapter. Part 1: Machine Elements in Motion Chapter 2 in this section is undoubtedly one of the most distinctive chapters you will find anywhere. There is page after page of diagrams of every conceivable mechanism and machine device.
There are snap-action mechanisms, linear actuators, fine adjustment devices, clamping and locating mechanisms, escapements and indexing mechanisms, oscillating mechanisms, ratchets and latches, reciprocating and reversing mechanisms, and couplings see the commercial designs in Chap.
There are devices that stop, pause, and hesitate motion, and devices that transport motion between machine elements. There are two pages of loading and unloading mechanisms, many that are commonly used for construction and earth-moving equipment, as well as bulk-handling railcars.
You will find path generators, function generators, and even mechanical computing mechanisms, still finding a place in this electronic age.
There are speed-changing mechanisms and multidegree mechanisms that form the basis of many robotic-type machines. I hope you enjoy as much as I do just flipping pages in this one-of-a-kind catalog of mechanical devices. If a particular linkage catches your eye in Chap.
Details of the famous slider-crank and fourbar linkages are provided. The material in this chapter might seem intimidating graphically, but without it, the preciseness of the motion you most likely need will be difficult to achieve any other way. If your machine requires a cam to achieve its design requirements, then Chap. From simplified schematics to the complexity of cam trigonometry, everything a designer will need is here in these pages.
There is even a computer program flowchart to help you develop a comprehensive analysis of your design, whether you use a programming code like FORTRAN or a personal computer spreadsheet.
The last chapter in this section, Gear Trains, presents all the relative speed calculations for the two most common arrangements of gears: spur and planetary.
Also, the speed calculations for differential gear trains are presented. Once these calculations are made, then the detailed specifications can be made using the information in Part 3. It contains information on every kind of spring, from the commonly used helical spring, with all its variations, to the unique Belleville spring washer. Elliptical and even torsion bar springs are covered. In fact, basically everything I know about springs is in this chapter, one of the longest in the Handbook.
They act like an accumulator tank in an air compressor system, thus evening out the fluctuations in rotational motion. Careful sizing is necessary to make sure that just the right amount of inertia is provided. Too much can cause the system to be have too long a recovery period or too little inertia, causing the system to loose too much energy between loading cycles. For high-speed flywheels or machine elements like compressor blades, consideration of the inertial stresses developed can be important.
The late John Muir, in his book How to Keep Your Volkswagen Alive, said, Brakes perform a negative function, applying negative acceleration to stop the car, remaining inert when not being used. Brakes may have a negative function; however, their design can be critical to a successful product.
Chapter 8 covers all aspects of brakes and all aspects of what might be the opposite of brakesclutches. Clutches are designed to transfer power evenly and gradually between two shafts rotating at different speeds, even when one shaft is at rest. There has been a great deal of ingenuity in the design of brakes and clutches, accounting for many patents and commercial products. Centrifugal, cone, and disk-type clutches and brakes are two such commercial success stories.
Both brakes and clutches produce significant temperature gradients in service. The design considerations associated with temperature variations are covered in this important chapter, including information on selecting the right clutch or brake materials for your specific application. Most of us as mechanical engineers will never actually be involved in designing and manufacturing gear sets, even the simplest spur gear.
