Brief Introduction To Hydraulic Safety Coupling
Jun 29, 2017

Hydraulic safety coupling is composed of double-layer sleeve, middle injection high-pressure oil after the outer sleeve expansion, depending on friction and hub locking, inner sleeve is compressed in the same shaft, the coupling can be transferred and oil pressure proportional torque. When the torque passed exceeds the predetermined torque value, the coupling slips on the axle (about a few seconds), the shearing tube is cut off, and the oil pressure is relaxed within seconds.

The lubricating oil between the sealing groove and the shaft seal will quickly spread to the shaft and the coupling, as is the sliding bearing. The replacement of the new shear tube and the injection of high-pressure oil will continue to operate.
