Couplings and Joints Design, Selection & Application 2nd Edition

The first edition of Couplings and Joints Design, Selection & Application 2nd Edition was published in 1986 and it took me 5 years to put it together. When I started work on this edition, I thought the task would be a lot simpler, but its preparation has taken me almost as long.

The flexible coupling method of connecting rotating equipment is a vital and necessary technique. Large shafts in loosely mounted bearings, bolted together by flanged rigid couplings, do not provide for efficient and reliable mechanical power transmission. This is especially true in today’s industrial environment, where equipment system designers are demanding higher speeds, higher torques, greater flexibility, additional misalignment, and lighter weights for flexible couplings. The need for flexible couplings is becoming more acute as is the need for technological improvements in them.

The basic function of a coupling is to transmit torque from the driver to the driven piece of rotating equipment. Clutches (which constitute another subject for a book and are not covered here) are couplings designed to cease transmitting torque at a certain load or speed. Flexible couplings expand upon the basic function by also accommodating misalignment and end movement. During the initial assembly and installation of rotating equipment, precise alignment of the equipment shaft axes is not only difficult to achieve, but in most cases it is economically prohibitive.
