Large Displacement Orbital Hydraulic Motors

Large Displacement Orbital Hydraulic Motors are high-displacement cycloidal hydraulic motors primarily used in low-speed, high-torque hydraulic drive systems. Through a cycloidal gear meshing structure, hydraulic energy is converted into mechanical rotational power, enabling direct drive of heavy-duty equipment.

In many heavy-duty equipment systems, traditional drive systems often require additional reduction gears. Yushan Intelligent Large Displacement Orbital Hydraulic Motors, however, can directly output high torque at low speeds, reducing transmission links, improving overall system efficiency, and simplifying equipment structure.

Core Product Features:

1. Low-Speed, High-Torque Output Structure

The large-displacement cycloidal structure allows Large Displacement Orbital Hydraulic Motors to output stable torque even at low speeds, suitable for heavy-load starts and continuous operation.

Key Features:

Displacement Range: 315–800 cm³/rev

Continuous Torque: Up to approximately 1400 N·m

Peak Torque: Exceeding 1600 N·m

Enables direct drive for heavy-duty equipment

This design reduces the use of transmission components such as gearboxes, simplifying the equipment structure.

2. Stable Energy Consumption Control

In equipment operating for extended periods, hydraulic system efficiency directly impacts operating costs.

Large Displacement Orbital Hydraulic Motors demonstrated stable efficiency metrics in testing:

Volumetric efficiency ≥ 93%

Mechanical efficiency ≥ 90%

This efficiency level reduces hydraulic system energy consumption under continuous operating conditions, thereby reducing long-term operating costs.

3. Pressure Capability for Heavy-Duty Operations

Heavy-duty equipment typically faces operating environments with significant pressure fluctuations; therefore, hydraulic motors need to possess high pressure tolerance.

Key specifications of this hydraulic motor model:

Continuous working pressure: 16 MPa

Peak pressure: 20 MPa

Mean time between failures (MTBF): 8000+ hours

The internal sealing structure has been optimized, enabling stable operation in complex environments such as dust and oil contamination.
