1.Product Overview:
The grader double universal joint drive shaft is a heavy-duty power transmission component specifically designed for road leveling, land grading, and similar engineering applications. It operates reliably under high-load, dusty, high-vibration, and large-angle deflection conditions. Featuring a double Cardan joint structure combined with dynamic compensation and fatigue-resistant design, it efficiently transmits power to core components such as the grader blade lifting system and rotor drive unit. It precisely adapts to terrain variations and operational angle changes, ensuring stable and continuous power transmission while minimizing equipment vibration and mechanical wear.
2. Product Features:
(1) High Load Capacity: Nominal torque range: 5,000–8,000 N·m; transient impact torque capacity up to 200% of nominal value, suitable for heavy-duty blade cutting and rotor crushing operations.
(2) Wide-Angle Compensation: Dual universal joint linkage supports multi-directional deflection for blade lifting, chassis tilting, and complex terrain adaptability.
(3) Dust & Contamination Resistance: Fully enclosed sealing design prevents sand and dust ingress into bearing chambers, extending service life.
(4) Lightweight & Efficient: Structural optimization and lightweight alloy materials reduce weight by 20–25% compared to traditional designs, enhancing grader maneuverability.
(5) Smart Lubrication Management: Pre-filled with long-lasting, high-temperature-resistant grease (-45°C to +120°C), featuring external grease fittings for rapid maintenance and reduced downtime.
3. Product Advantages:
(1) Precision Power Transmission: Optimized phase angle design achieves ≥97% transmission efficiency, minimizing energy loss and heat generation.
(2) Exceptional Durability: Passes 300,000 fatigue cycles and 100-hour salt spray testing, offering 40% longer lifespan than conventional products.
(3) Rapid Maintenance Design: Modular structure enables individual replacement of bearings and seals, lowering repair costs.
(4) Certification Compliance: Meets ISO 9001, CE standards, and construction machinery industry norms (e.g., GB/T 14781).
