液力偶合器的工作原理（The working principle of hydraulic coupling）

液力偶合器的工作原理（The working principle of hydraulic coupling） The working principle of hydraulic coupling A kind of non rigid coupling with liquid as working medium, also called hydraulic coupling. The hydraulic coupling pump wheel and turbine form a closed working chamber that can circulate the liquid, the pump wheel is mounted on the input shaft, and the turbine is mounted on the output shaft. When a power machine (an internal-combustion engine, an electric motor, etc) drives the input shaft to rotate, the liquid is thrown out by the centrifugal pump wheel. The high speed liquid enters the turbine, which pushes the turbine to rotate and transfers the energy from the pump wheel to the output shaft. Finally, the liquid returns to the pump wheel to form a cycle of fluid. A hydraulic coupler transmits torque by varying the angular momentum of the fluid with the impeller of the pump and turbine blades. Its output torque is equal to the input torque minus the friction torque, so its output torque is always less than the input torque. Hydraulic coupler between the input shaft and the output shaft by the liquid connection, there is no rigid connection between the work components. The characteristics of hydraulic coupler is to eliminate shock and vibration; the output speed is lower than the input speed, two speed difference increases with the increase of load; overload protection performance and good starting performance, while the load is too large to stop when the input shaft can rotate, not to damage the machine; when the load is reduced, the output shaft speed increase until close to the speed of the input shaft, the transmission torque tends to zero. The transmission efficiency of hydraulic coupler is equal to the ratio of the output shaft speed to the input shaft speed. The general hydraulic coupler can achieve higher efficiency when the speed ratio of the normal working condition is more than 0.95. The characteristics of the hydraulic coupler vary with the shape of the p
