Power transmission
The term power transmission describes a technical possibility of transmitting a force or torque within an assembly , a technical system or a machine between different components . One differentiates:
Static power transmission
The aim of static power transmission is to create a balanced state in an assembly or in a technical system in terms of statics (physics) . The movement of an assembly is prevented by the sum of all forces being "zero". An externally applied force or moment is therefore absorbed by a component and, with the help of the component connections, passed on to the bearings for compensation .
Dynamic power transmission
The dynamic power transmission will power transmission called. With a force transmission in the sense of dynamics (physics) a distance is overcome and if necessary the direction and the amount of the physical quantities force or moment are changed. Furthermore, there is often the possibility of regulation or control. It is present in every drive in technology . An assembly that transmits power within a larger technical system such as a vehicle and converts torque and speed is called a transmission . One differentiates:
- Mechanical power transmission: Only mechanical parts such as wheels ( toothed , chain , friction wheels , belt pulleys or cranks ), eccentrics and shafts are used. Examples of this are: manual transmission in vehicles , transmission (mechanical engineering) , diesel-mechanical drive and others.
- Electric power transmission: Electricity is generated in order to recover mechanical energy. Examples: see diesel-electric drive .
- Hydraulic power transmission: A liquid is used as a fluid in the sense of hydraulics . One distinguishes
- hydrostatic power transmission with piston engines and
- hydrodynamic power transmission with flow machines . (For example the fluid transmission of a diesel-hydraulic drive .)
- Pneumatic power transmission: This corresponds to hydraulic power transmission, but compressed air is used as the fluid. Pneumatic transmissions are not known. However, for example, workplaces in industry that are equipped with impact wrenches or other pneumatic tools driven by compressed air can be understood to mean that there is a pneumatic power transmission from the compressor via compressed air lines to drive the machine.
