XCMG 17 Travel Motor Assembly - Piston-Type Hydraulic Motor: Detailed Overview
I. Core Product Positioning
The XCMG 17 Travel Motor Assembly is a high-performance hydraulic drive component specifically designed for the travel systems of construction machinery. Utilizingpiston-type hydraulic motor technology, it features high torque output, strong low-speed stability, and high-pressure resistance. It is widely applied in crawler or wheeled travel mechanisms of excavators, loaders, and other equipment.
II. Technical Analysis of Piston-Type Hydraulic Motors
1. Structural Features
• Piston Arrangement: Adopts axial or radial piston configurations (e.g., 8-piston design). Hydraulic energy is converted into mechanical rotational energy through the interaction between pistons and the swashplate (or cam).
• Port Configuration: Labeled as "8:8 ports," this likely refers to the number of inlet and outlet ports or piston bore distribution, ensuring efficient hydraulic oil flow and minimizing pressure loss.
• Sealing & Durability: High-precision sealing technology between pistons and cylinder blocks prevents hydraulic oil leakage, adapting to high-load, high-frequency operating conditions.
2. Performance Advantages
• High Torque Output: Generates substantial torque even at low speeds, meeting demands for climbing and obstacle negotiation.
• Wide Speed Range: Enables stepless speed adjustment via hydraulic oil flow regulation, suitable for diverse applications.
• Strong Contamination Resistance: Piston designs are less sensitive to hydraulic oil cleanliness, thriving in harsh environments.
• High Efficiency: Superior mechanical and volumetric efficiency compared to gear motors, reducing energy consumption.
III. Application Scenarios for XCMG 17 Travel Motor Assembly
• Primary Equipment: Mainly配套 (matches) XCMG 17-ton excavators (e.g., XE17U) and other equivalent construction machinery.
• Work Condition Adaptability:
• Excavation Operations: Provides stable driving force for flexible steering and travel on complex terrains.
• Heavy-Duty Climbing: High-torque performance ensures power retention on muddy, sandy, or low-traction surfaces.
• Precision Control: Integrates with hydraulic systems for micro-movement control, enhancing loading and grading accuracy.
IV. Technical Parameters (Reference for Similar Industry Products)
• Displacement: 50–150 mL/r (varies by model).
• Rated Pressure: 25–35 MPa, compatible with high-pressure hydraulic systems.
• Speed Range: 0–300 rpm (exceptional low-speed stability).
• Output Torque: Peak torque up to 5,000–8,000 N·m (model-dependent).
• Weight: Assembly weight approximately 80–150 kg, facilitating installation and maintenance.
V. Selection & Maintenance Recommendations
1. Key Selection Criteria
• Confirm equipment tonnage and travel system requirements to match motor displacement and pressure ratings.
• Prioritize OEM-certified assemblies (e.g., XCMG-approved models) for compatibility.
• For severe conditions, opt for enhanced sealing or high-temperature-resistant materials.
2. Maintenance Guidelines
• Hydraulic Oil Management: Regularly replace hydraulic oil, maintaining cleanliness (NAS 9 grade or lower).
• Temperature Monitoring: Avoid prolonged high-temperature operation (recommended oil temperature ≤80°C) to prevent seal degradation.
• Periodic Inspections: Check for piston wear, oil seal leaks, and abnormal noises; replace vulnerable components promptly.
