I. Product Overview
A hydraulic orbit motor is a type of hydraulic motor that employs an orbit gear (Geroler) design. It features a compact structure, high efficiency, and stable pressure. It is widely used in construction machinery, agricultural machinery, industrial vehicles, environmental protection equipment, and other fields, providing high torque and stable rotational power to meet the needs of various hydraulic systems.
II. Structural Features
1. Orbit Gear Design:
• Utilizes advanced orbit gear (Geroler) design, characterized by low starting pressure, smooth and reliable operation, and high efficiency.
• The gap between the gear and the housing is maintained stable through precision machining and special design, reducing internal leakage and enhancing volumetric efficiency.
2. Output Shaft and Bearings:
• The output shaft adopts tapered roller bearings capable of withstanding high axial and radial forces, suitable for high-pressure and high-torque applications.
• The bearing design is optimized to extend the motor's service life and reduce maintenance requirements.
3. Disc-Type Porting Design:
• Employs advanced disc-type porting design, automatically compensating for gap variations during operation to maintain high volumetric efficiency and longevity.
• The precise fit between the porting disc and the gear reduces pressure fluctuations and noise, enhancing operational smoothness.
4. Modular Design:
• The hydraulic orbit motor typically features a modular design, facilitating easy repair and replacement of parts, and minimizing downtime.
• Multiple mounting forms and oil port connection options are available for easy matching with different equipment.
III. Performance Advantages
