What is a hydraulic coupling?
What is a hydraulic coupling? A hydraulic coupling is a device that uses hydraulic power to connect two axes and transmit torque. It usually consists of an inner and outer sleeve, a spring, a sealing ring and a liquid. The working principle of the hydraulic coupling is that when the two shafts rotate, the inner and outer sleeves drive the liquid to rotate together. The fluid enters the inlet of the hydraulic coupling and forms a layer of hydraulic pressure in the casing. This hydraulic pressure connects the inner and outer sleeves together so that they achieve the effect of coupling. At the same time, hydraulic couplings provide additional connection and sealing by means of springs and sealing rings. The spring makes the coupling have a certain elasticity, which can absorb and relieve the shock and vibration between the shafts. The sealing ring prevents liquid leakage and ensures stable operation of the hydraulic coupling. Hydraulic couplings...
