1.Product Description
The excavator wheel axle shaft assembly is a core component of construction machinery drive systems, designed to transmit power to the drive wheels, supporting heavy-load operations, slope climbing, steering, and multi-condition adaptability in complex terrains such as mines and construction sites. Its high-strength torsion-resistant structure, impact resistance, and dynamic sealing technology ensure stable power transmission and long-term durability in muddy, rocky, and high-vibration environments, making it a critical component for excavator mobility and operational efficiency.
2. Product Features
(1) Heavy-Duty Torsion-Resistant Design
Manufactured from high-strength alloy steel via integral forging, surface hardening, and precision grinding, achieving surface hardness of HRC 55-60 and tensile strength ≥1,200 MPa, suitable for extreme load conditions of 20–50-ton excavators.
(2) All-Condition Sealing Protection
Multi-layer sealing system (dust cover + fluororubber lip seals) with IP68/IP69K protection, effectively resisting mud, sand, and high-pressure water washout. High-temperature grease (operating range: -45°C to 120°C) ensures extended maintenance intervals.
(3) Lightweight & Compact Structure
Optimized with high-strength alloy materials, reducing weight by 20% while maintaining torque capacity, suitable for flexible steering and chassis layout in confined spaces.
3. Product Specifications
| Category | Parameters |
| Applicable Models | 5–50-ton wheeled hydraulic excavators (standard, mining-enhanced) |
| Rated Torque | 8,000–29,500 N·m |
| Safety Factor | ≥4.5 |
| Maximum Speed | 1,500 rpm |
| Maximum Angle | 45° |
| Design Lifespan | ≥12,000 hours (standard conditions) |
| Protection Rating | IP68/IP69K (mudproof, high-pressure jet resistant) |
| Operating Temperature | -45°C to +120°C |
| Certifications | ISO 9001, CE, GB/T 9139 (Construction Machinery Strength Standard), ISO 3457 (Sealing Performance Certification) |
4. Application Scenarios
(1) Mining Operations: Withstands impacts and vibrations from high-intensity rock excavation and heavy-load transport.
(2) Municipal Engineering: Adapts to frequent start-stop, narrow-space steering, and complex motion requirements in urban construction sites.
(3) Farmland & Water Conservancy: Resists corrosion in humid, muddy environments, ensuring reliability in long-term paddy field operations.
(4) Post-Disaster Rescue: High-mobility design supports rugged terrain and rapid movement needs.
(5) Polar Construction: Ultra-low-temperature grease version ensures stable operation in -50°C extreme cold.
5. Customization: OEM customization supported.
6. Product Advantages:
(1) Extreme Condition Adaptability: Reinforced bearing housing and flange design withstands mining overloads and continuous impacts.
(2) Quick Maintenance Design: Modular split structure enables replacement within ≤40 minutes.
(3) Environmental Compatibility: Optional acid-resistant plating (for chemical waste scenarios) or anti-rust coatings (for coastal salt spray environments).
(4) Energy Efficiency: ≥98% transmission efficiency reduces energy loss, improving fuel economy (for combustion models) or battery life (for electric models).
