As a part of a series of technical handbooks developed for the European manufacturing industry, R+W has released a new handbook for the design and application of safety and overload couplings. Covering the very basics of what torque limiters are, the varieties available, and why they are used, all the way though complex theories and advanced sizing formulas used to determine optimum coupling selection, this handbook includes information for all levels of design engineers with a potential need for torque overload protection. This is the second of a two part series, with the first book handling the design and application of precision couplings and line shafts.
