The components of a Roots blower
Any machine is made up of a combination of many components. For example, a single-cylinder combustion engine is composed of a cylinder, piston, connecting rod, crankshaft, bearing and other components. There is a definite relative motion between the moving entities. It can realize the conversion of energy, replace or alleviate human labor, and complete useful mechanical work. For example: generators can convert mechanical energy into electrical energy; Transport machines can change the position of objects in space; Metal cutting machine tools can change the size and shape of the workpiece; Computers can transform information and so on.
According to the above analysis, a clear conception of the machine can be obtained: the machine is a combination of human entities (components), its parts have a definite relative movement between them, and can replace or alleviate human manual labor, complete useful mechanical work or achieve energy conversion. According to its use, the machine can be divided into engine (prime mover) and work machine. An engine is a machine that converts non-mechanical energy into mechanical energy. For example, an electric motor is a machine that converts electrical energy into mechanical energy, and an internal combustion engine is a machine that converts thermal energy into mechanical energy.
A work machine is a machine used to change the position, shape, performance, size and condition of the material being processed. The working machine is a machine that uses mechanical energy to do useful work, such as lathes, milling machines and other metal cutting machine tools are all working machines. Mechanisms are systems of components used to transmit motion and forces. One of the components in the component system is the rack, and the component system is connected with a motion pair. Compared with machines, mechanisms are also a combination of human entities (components), and there is also a definite relative movement between the moving entities, but they cannot do mechanical work or achieve energy conversion.
The difference between the machine and the mechanism is that the main function of the machine is to use mechanical energy to do work or realize the conversion of energy; The main function of the institution is to transmit or transform the form of the movement. For example, aero engines, machine tools, rolling mills, textile machines and tractors are all machines, while clocks, meters, jacks, variable speed devices or indexing devices in machine tools are all mechanisms. Usually a machine must contain one or more mechanisms. If you do not consider doing work or achieving energy conversion, there is no difference between machine and mechanism only from the point of view of structure and motion, and they are collectively referred to as machinery, that is, machinery is the general term for machine and mechanism.
