What is the oil volume of a hydraulic coupling?

[Blakely]

The oil filling volume of a hydraulic coupling is 70%-80%. For standard torque-limiting hydraulic couplings, the filling volume corresponding to the rated power is 80%, not fully filled. The oil filler port should be tilted at a 45-degree angle from the vertical direction, and oil should be added until it just starts to flow out. Typically, the oil filling range for YOX-type couplings is 40%-80%. Depending on their application, hydraulic couplings are classified into standard hydraulic couplings, torque-limiting hydraulic couplings, and speed-regulating hydraulic couplings. Torque-limiting hydraulic couplings are mainly used for motor and gearbox start-up protection, impact protection during operation, position compensation, and energy buffering. Speed-regulating hydraulic couplings are primarily used to adjust the input-output speed ratio, with other functions being essentially the same as torque-limiting hydraulic couplings. Precautions for using hydraulic couplings: Avoid sudden forward and reverse rotation. Sudden forward and reverse rotation can damage the coupling's connecting components due to excessive inertia. Strictly adhere to operational procedures.
