The hydraulic safety coupling is composed of a double-layer sleeve. After injecting high-pressure oil in the middle, the outer sleeve expands and locks with the wheel hub by friction, while the inner sleeve compresses inward and holds coaxially. The coupling can transmit torque proportional to the oil pressure. When the transmitted torque exceeds the predetermined torque value, the coupling slips on the shaft (about a few hundredths of a second), the shear tube is cut off, and the oil pressure will relax within a few thousandths of a second. The lubricating oil sealed between the inner groove and the shaft seal will quickly spread between the shaft and the coupling, just like a sliding bearing. Replace the cutting tube with a new one
Compact structure, small mass, small radial size, small moment of inertia, easy to connect with other transmission components. Not affected by metal fatigue, it can ensure a longer period of time to limit the predetermined torque of the transmission. It can play a sensitive role in overload safety protection. By controlling the pressure of the injected pressure oil, the transmitted torque can be adjusted over a large range. Transmission balance, capable of buffering and vibration reduction, suitable for forward and reverse working conditions. Replacing vulnerable parts (shear tubes) is more convenient and reduces auxiliary work hours. Easy maintenance and low cost.
