What is the oil volume of a hydraulic coupling?

[Josie]

The oil filling volume for a hydraulic coupling is 70%-80%; for ordinary torque-limiting hydraulic couplings, the filling volume is 80% of the rated power. Typically, the oil filling range for YOX-type couplings is 40%~80%. Precautions for using hydraulic couplings: 1. Avoid rapid and frequent forward and reverse rotations. 2. The rotation direction of the coupling's output shaft should match that of the motor shaft. During the initial test run, check if the motor rotation direction meets the requirements. 3. When the motor reaches the rated speed, the driven machine must start operating. If the driven machine does not move, immediately shut down and check if the load is too heavy, causing a braking effect. 4. During continuous operation, the coupling's working temperature must not exceed 90°C. 5. Regularly (every 3000 hours) check the oil quality. If the oil quality deteriorates, replace it immediately. 6. Periodically inspect the positional accuracy between the motor shaft and the working machine shaft and correct it as needed. 7. Regularly check the installation foundation of the motor and working machine to avoid early damage caused by poor foundation rigidity, which can lead to vibration and coupling issues. 8. Regularly inspect the wear of the elastic blocks or discs in the flexible coupling and replace them periodically. 9. Do not disassemble the coupling housing arbitrarily to avoid compromising sealing, assembly precision, and balance accuracy, which could lead to accidents. 10. Do not replace the coupling oil medium with water. 11. Do not fill the coupling arbitrarily, and never fill it completely. Strictly follow the filling instructions in the manual.
