WEAウォームギア旋回ドライブ WEAウォームギア旋回ドライブ
    The WEA Series represents the pinnacle of our heavy-duty engineering capabilities. Unlike conventional drives that rely on a single worm wheel engagement, the WEA utilizes a unique dual-worm gear configuration . This design features two precision-ground worms engaging a single globoid wheel from opposite sides (or in a synchronized tandem arrangement). The result is a mechanical marvel: torque capacity is effectively doubled , shock loads are distributed across two contact zones, and the system gains inherent symmetry that cancels out radial forces, drastically extending bearing life. Housed within a robust, fully enclosed ductile iron casing rated up to IP68 , the WEA Series is built to survive where others fail. As a specialized Chinese manufacturer of heavy-motion systems , we have deployed these drives in some of the world's harshest environments—from the gale-force winds of offshore wind farms to the abrasive dust of open-pit mines—proving that when the stakes are high, the WEA Series is the only choice.

Product Series Overview: Built for the Extremes

The WEA Series Dual Worm Gear Drive is not an off-the-shelf component; it is a custom-engineered solution for applications where failure is not an option.
  • Twin-Worm Architecture: The defining feature. Two high-hardness alloy steel worms mesh simultaneously with the central wheel, sharing the load 50/50. This eliminates the "weak link" scenario and provides a massive safety margin.
  • Heavy-Duty Enclosed Housing: Cast from high-grade ductile iron (QT500-7 or higher), the housing acts as a structural shield. It features reinforced ribs to absorb vibration and prevent deformation under extreme torque.
  • Multi-Stage Sealing System: Equipped with labyrinth seals, high-performance lip seals, and optional magnetic plugs, the WEA Series achieves IP66/IP67/IP68 ratings. It keeps contaminants out and lubricant in, even under submersion or high-pressure washdowns.
  • Symmetrical Load Distribution: The dual-input design balances radial forces on the output shaft, reducing stress on the internal bearings and allowing for higher overhung loads.
  • Modular Input Options: Designed to accept dual hydraulic motors, dual electric motors, or a combination thereof, offering flexibility in power source and redundancy.


Key Features: Why the WEA Series Dominates Heavy Applications

Why specify a heavy type enclosed housing dual worm gear slewing drive for your critical project? The operational advantages are transformative:
  1. Double the Torque, Same Footprint: By utilizing two worms, the WEA Series delivers approximately 2x the holding and driving torque of a comparable single-worm unit without significantly increasing the overall size. This allows for downsizing the overall system while increasing payload capacity.
  2. Unmatched Shock Load Resistance: In applications like crane lifting or wind-swept solar tracking, sudden impacts are common. The dual-gear engagement acts as a natural shock absorber, distributing impact energy across two gear meshes and preventing tooth fracture.
  3. Redundancy and Safety: If one input source (e.g., a hydraulic motor) fails, the second worm can often maintain position or allow for controlled emergency movement, depending on the configuration. This adds a critical layer of operational safety.
  4. Extended Service Life in Harsh Conditions: The fully enclosed, sealed design protects the precision gears from abrasive dust, salt spray, and moisture. Combined with our synthetic long-life lubricants, the WEA Series offers maintenance intervals far exceeding industry standards.
  5. Superior Stability & Precision: The symmetrical force application minimizes deflection and backlash, ensuring smooth, precise rotation even under maximum load. This is crucial for applications requiring accurate positioning, such as radar antennas or large telescopes.


Applications: Powering the World's Heaviest Machinery

The WEA Series dual worm gear drive is the preferred solution for industries demanding ultimate reliability:
  • Utility-Scale Solar Trackers: Specifically for large dual-axis trackers in windy regions. The dual-worm design handles high wind loads effortlessly, ensuring panels stay locked in position during storms.
  • Heavy-Duty Cranes & Hoists: Ideal for the slewing mechanism of mobile harbor cranes, floating cranes, and heavy-lift construction equipment where load safety is paramount.
  • Offshore & Marine Equipment: Perfect for winches, deck cranes, and ROV launch systems. The IP68 rating and corrosion-resistant coatings withstand the brutal marine environment.
  • Mining & Excavation: Used in large excavators, draglines, and mining shovels where dust ingress and shock loads are constant challenges.
  • Radar & Satellite Communication: Provides the stable, vibration-free platform needed for large military and civilian radar dishes and satellite ground stations.
  • Wind Turbine Yaw Systems: While typically planetary, specific heavy-duty yaw applications benefit from the self-locking and high-torque density of the WEA dual-worm design.


Why Partner with Us? Your Source for Heavy-Duty Innovation

Sourcing heavy-duty dual worm gear drives from China requires a partner with deep metallurgical knowledge and advanced machining capabilities. Here is why global OEMs trust our facility for the WEA Series:
  • Specialized Twin-Worm Manufacturing: Producing synchronized dual-worm sets requires exceptional precision. Our factory utilizes advanced 5-axis CNC grinding centers to ensure both worms match the globoid wheel profile perfectly, guaranteeing equal load sharing.
  • Robust Quality Assurance: Every WEA unit undergoes rigorous full-load testing, including dynamic shock simulations, seal integrity pressure tests, and endurance runs under extreme temperatures. We provide full traceability and material certifications (MTRs).
  • Custom Engineering for Extreme Environments: We don't just sell standard boxes. Our engineers work with you to customize housing materials (e.g., stainless steel cladding), sealing grades, and gear ratios to suit specific environmental challenges like Arctic cold or tropical humidity.
  • Vertical Integration: From casting our own housings to heat-treating gears and assembling final units, we control every step of the process. This ensures consistent quality and faster lead times compared to assembled-only suppliers.
  • Cost-Effective Heavy Duty Solutions: We deliver European-level performance and durability at a competitive price point, helping you reduce CAPEX on large-scale projects without compromising on safety or longevity.
