III. Structural Components
TheXZ-36000consists of the following core parts:
1. High-Speed Hydraulic Motor
• Utilizes radial piston or ball-piston design (e.g., A2FE80/90 series) for efficient hydraulic energy conversion.
2. Planetary Gearbox
• Multi-stage planetary gear transmission achieves high reduction ratios and torque output.
3. Brake System
• Hydraulically controlled braking ensures rapid response and stability on slopes or during stops.
4. Valve Assembly
• Integrated pressure compensation valves and relief valves optimize system pressure control to prevent overloading.
5. Housing and Drive Design
• Directly connects to crawler drive wheels or vehicle wheels, minimizing transmission losses and improving efficiency.
IV. Technical Advantages
1. High Load-Bearing Capacity
• Tapered roller bearings withstand axial and radial forces during excavator operation, extending service life.
2. Patented Technology
• National patent-awarded design ensures structural optimization and stable performance, replacing imported alternatives.
3. Versatility
• Compatible with drilling rigs, trenchless rigs, rotary drilling rigs, and tunneling machines for diverse industrial needs.
4. Energy Efficiency
• Low-speed, high-torque output reduces energy waste and enhances overall equipment efficiency.
V. Application Scenarios
1. Drilling Rigs
• Serves as the crawler travel drive for horizontal directional drilling rigs (e.g., XCMG XZ3600), providing stable thrust (max. 6,600 kN) and rotational torque (120,000 N·m).
2. Excavators
• Replaces traditional mechanical transmissions in medium-sized excavators (e.g., Hitachi ZX360H-5G), improving mobility and gradeability (70% slope capacity).
3. Engineering Vehicles
• Used in rail vehicles or heavy-duty transport equipment for low-speed, high-torque locomotion.
VI. Selection and Installation Guidelines
1. Parameter Matching
• Choose models (e.g., XZ-30000 or XZ-36000) based on equipment weight, travel speed, and load requirements.
2. Installation Requirements
• Ensure a flat mounting surface to avoid misalignment; align crawler drive wheels precisely to minimize vibration.
3. Maintenance
• Regularly inspect hydraulic oil cleanliness and replace filters; verify brake performance to prevent failure.
