2. Model Breakdown (101-1003-009)

【表格】

Code Segment Meaning Possible Parameters

101 Series Code Base orbital motor series with standard structure/performance

1003 Displacement Identifier Displacement 10.03 in³/rev (164.4 cm³/rev)

009 Configuration Code Port type, shaft design, or seal rating (e.g., SAE flange, keyed shaft)

3. Core Performance Parameters

【表格】

Parameter Value Description

Displacement 10.03 in³/rev (164.4 cm³/rev) Oil volume per revolution, determining torque output

Rated Pressure 3000 psi (207 bar) Continuous operating pressure

Peak Pressure 3500 psi (241 bar) Short-term maximum allowable pressure

Max Speed 500 rpm Speed under no-load/light-load conditions

Continuous Torque ~1200 lb·ft (1627 N·m) @2000 psi Calculated: Torque = Displacement × Pressure × Efficiency / 2π

Mechanical Efficiency ≥85% Energy conversion efficiency

Volumetric Efficiency ≥90% Internal leakage control

Weight ~45 lb (20.4 kg) Including housing, shaft, etc.

4. Structural Features

• Orbital Gear Design: Uses cycloidal gearing for low-speed, high-torque output with minimal vibration.

• Axial Compensation: Built-in axial clearance adjustment to reduce wear and extend lifespan.

• Bearing Configuration: Dual-row tapered roller bearings for radial/axial load support in heavy-duty applications.

• Sealing System: Dual lip seals + dust wiper to prevent leaks and external contamination.

• Modular Design: Supports customizable shaft types (keyed, splined, flange) and port configurations (SAE/BSP threads).

5. Typical Applications

• Construction Machinery: Excavator slewing drives, crane winches, road roller vibration wheels.

• Agricultural Equipment: Combine harvester header drives, tractor hydraulic lift systems.

• Industrial Machinery: Injection molding machine clamping, metal die-casting machine mold closing.

• Marine Propulsion: Outboard motors or deck machinery drives for small vessels.

6. Installation & Maintenance

• Mounting Orientation: Horizontal or vertical installation allowed, but ensure ports face upward to avoid cavitation.

• Fluid Requirements:

• Viscosity: 15–400 cSt (at 40°C)

• Cleanliness: NAS 1638 Class 8 or ISO 4406 19/17

• Recommended Fluids: Mineral oil, synthetic hydraulic fluid (with anti-wear additives)

• Maintenance Schedule:

• Oil change and seal inspection every 1000 hours.

• Gear/bearing inspection every 2000 hours.
