This book briefly introduces the basic design and calculation methods of the four major categories of mechanical parts commonly used in engineering - connecting parts, transmission parts, shafting parts and elastic elements. Specifically, it includes: connecting parts - threaded connectors, screw drives, keys, pins; transmission parts - belts (including V-belts, synchronous belts and flat belts), chains, gears, worm gears; shafting components - shafts, rolling bearings, sliding bearings, couplings, clutches, brakes; elastic elements - cylindrical spiral compression springs, cylindrical spiral tension springs, disc springs, air springs and leaf springs. The content is basic and the examples are representative, so it has strong practicality.
