Deskripsi
Torque Limiting Hydraulic Coupling
• Series: YOX (constant filling fluid coupling series)
• Model: YOX600
• Brand : Dalian Hydraulic Machinery
Product Overview:
The YOX600 is a constant filling, torque-limiting hydraulic (fluid) coupling used in heavy-duty rotating equipment. It transmits torque through hydrodynamic oil flow, enabling:
- Soft start of motors
- Overload protection for gearboxes and driven machinery
- Shock absorption during startup and load fluctuations
Spare Part List (Typical):
- Pump wheel (impeller)
- Turbine wheel
- Outer casing / housing
- Oil filling plug & drain plug
- Torque-limiting chamber
- Shaft sleeves & keyways
- Bearings & seals
- Gaskets & O-rings
Specifications:
- Impeller Diameter: 600 mm
- Max Speed: 1500 RPM
- Torque Limiting Ratio: 2.0–2.5
- Oil Filling Volume: ~180–200 kg
- Material: Cast steel housing, alloy impellers
- Mounting: Shaft-to-shaft flexible connection
- Lubricant: Mineral oil or fire-resistant fluid
