Introduction to mechanical parts

A discipline that studies and designs the mechanical basic components in various devices, and also refers to parts and components in general terms. The specific content of mechanical parts as a discipline includes: 1. Connection of parts (components). Such as threaded connection, wedge connection, pin connection, key connection, spline connection, interference fit connection, elastic ring connection, riveting, welding, and bonding. 2. Mechanical transmissions that transmit motion and energy, such as belt transmission, friction wheel transmission, key transmission, harmonic transmission, gear transmission, rope transmission, and screw transmission, as well as corresponding shafting parts (components) such as transmission shafts, couplings, clutches, and brakes. 3. Parts (components) that serve as supports, such as bearings, housings, and machine bases. 4. Lubrication systems and seals that serve a lubricating function. 5. Other parts (components) such as springs. As a discipline, mechanical parts starts from the overall perspective of mechanical design, comprehensively utilizes the achievements of various related disciplines, studies the principles, structures, characteristics, applications, failure modes, load-bearing capacities, and design procedures of various basic components; studies the theories, methods, and criteria for designing basic components, and thereby establishes a practical theoretical system for this discipline, becoming an important foundation for researching and designing machinery.
