Product Description
Yile Machinery is an expert manufacturer of high-torque planetary gearboxes designed for the demanding applications of excavator final drives (travel motors) and swing drives. We produce complete, fully assembled gearbox units that serve as direct OEM replacements or high-quality aftermarket solutions for a wide range of mining and construction excavators.
Our gearboxes are engineered to deliver reliable power and withstand the extreme shock loads and continuous duty cycles found in mining, quarrying, and heavy construction environments.
The final drive and swing drive are the critical components that convert hydraulic power into mechanical motion.
Final Drive / Travel Motor: This planetary gearbox assembly provides the high torque and low speed required to propel the excavator's tracks, enabling powerful and precise movement across rugged terrain.
Swing Drive / Swing Motor: This unit powers the rotation of the excavator's upper structure (the house) on its undercarriage, allowing for efficient digging, loading, and material placement.
Every gearbox we produce is built for maximum durability and performance. We control the entire manufacturing process, from raw material to final testing.
1. Advanced Planetary Gear Design
Our gearboxes utilize a multi-stage planetary gear system, which is the industry standard for its ability to handle immense torque within a compact design.
Gears are precision-cut from high-strength, case-hardened alloy steels (e.g., 20CrMnTi) for exceptional wear resistance and load-bearing capacity.
2. Precision Machining & Assembly
All components, including the main housing, carriers, and shafts, are precision-machined on CNC equipment to ensure perfect alignment and interchangeability.
Gear teeth are finished using gear shaping, hobbing, and grinding processes to achieve a smooth, quiet, and efficient power transmission.
Units are assembled in a clean environment and fitted with high-quality bearings and seals to prevent contamination and ensure a long service life.
3. Rigorous Quality Assurance & Testing
Before shipment, each final drive and swing drive assembly undergoes comprehensive testing to verify performance under simulated load conditions.
We check for proper gear meshing, torque output, and operational smoothness to guarantee the unit is ready for immediate installation and reliable service.
We have the capability to manufacture final drives and swing drives that are compatible with excavators from all major manufacturers. Whether you need a direct replacement part identified by a part number or require a custom-engineered solution, we are your trusted manufacturing partner.
