Features
• Ultra-High Torque & Load Capacity
Symmetrical dual worm drive design doubles the torque output, with a maximum output torque of up to 8000N·m and a rated overturning moment of 500kN·m, capable of bearing ultra-heavy axial/radial forces in large-scale equipment.
• Zero-Backlash Precision Positioning
The dual worms are precision meshed with the worm wheel and the clearance is adjustable, achieving ±0.01° rotation accuracy and eliminating transmission backlash, meeting the high-precision positioning needs of aerospace and defense equipment.
• Redundant Safety Design
In case of a single worm drive failure, the other worm can independently maintain basic rotation operation, preventing sudden equipment downtime and ensuring operational safety in critical working conditions.
• Multi-Level Sealing Protection
Combined skeleton oil seal + labyrinth seal + grease seal structure achieves IP67/IP68 protection rating, effectively preventing the intrusion of seawater, dust, and corrosive media, adapting to marine, mining and other harsh environments.
• Low Heat Generation & Stable Operation
Optimized worm gear tooth profile and high-precision machining reduce meshing friction; the dual worm load-sharing design lowers heat generation by 40% compared with single worm drives, ensuring long-term continuous operation without overheating.
• Modular Maintenance
The dual worm units adopt a modular design, which can be disassembled and maintained separately without removing the entire slewing drive, reducing maintenance time and costs by 50%.
Comprehensive Competitive Advantage
• ISO9001 & CE Certified: Complies with international quality management standards and EU machinery safety directives, ensuring product reliability and global market access.
