What are the common Machine element

Common Machine element are as follows:

Inclined Simple machine: inclined plane, spiral, split.

Lever Simple machine: lever, pulley, axle, gear.

The engagement of rotating components in opposite directions, such as gears, mixing rollers, etc.

The rotating shaft includes connectors, mandrels, chucks, screws, and rods.

Rotating protrusions and holes. Rotating components containing protrusions or cavities are very dangerous, such as fan blades, cams, flywheels, etc.

The intersection between rotating components and tangent moving components, such as power transmission belts and pulleys, chains and sprockets, racks and gears, etc.

Origin:

Since the emergence of machinery, there have been corresponding Machine element. But as a discipline, Machine element are separated from mechanical structure and mechanics. With the development of machinery industry and the emergence of new design theories and methods, new materials and new processes, Machine element have entered a new stage of development.

The theories of finite element method, Fracture mechanics, elastohydrodynamic lubrication, optimal design, reliability design, Computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology have gradually been applied to the research and design of Machine element.

It is an important trend for the development of this discipline to better realize the integration of multiple disciplines, realize the combination of Microcosm–macrocosm analogy, explore new principles and structures, adopt more dynamic design and accurate design, more effectively use electronic computers, and further develop design theories and methods.
