Introduction to mechanical parts
Machine element is also called machine part
The basic elements of machinery are indivisible single systems that make up machinery and machines
Machine element is also called machine element
Part) is the basic element of machinery, which is inseparable from machinery
Mechanical parts are a subject of studying and designing mechanical basic parts in various equipment
Section is also a general term for parts and assemblies.
Research and design of mechanical basic parts in various equipment is also a subject of parts
And components. The specific contents of mechanical parts as a discipline include: 1. Zero
Connection of components. Such as threaded connection, wedge connection, pin connection, key connection and spline connection
Connection, interference fit connection, elastic ring connection, riveting, welding and bonding, etc.
2. Belt drives, friction wheel drives, key drives, harmonics that transmit motion and energy
Transmission, gear transmission, rope transmission, screw transmission and other mechanical transmission, as well as transmission
Shaft, coupling, clutch, brake and other corresponding shafting components.
3. The supporting parts (components), such as bearings, boxes and bases.
4. Lubrication system and seal for lubrication.
5. Other parts (components) such as springs. As a discipline, mechanical parts are developed from
Design as a whole, comprehensively use the achievements of various disciplines, and study various foundations
Principle, structure, characteristics, application, failure form, bearing capacity and design process of components
Sequence; Research the theory, method and criterion of design basic parts, and establish the discipline
The theoretical system based on the combination of practice has become an important basis for the research and design of machinery.
