Belparts excavator parts hyundai R210LC-7 31N6-10180 Swing Reduction Motor Assy

The slewing gearbox (also called the swing drive or rotary gearbox) is a critical component in excavators, enabling 360-degree rotation of the upper structure (house) relative to the undercarriage. It ensures precise movement, load-bearing capacity, and torque transmission during excavation, lifting, or material handling operations.

Working Principle

The slewing gearbox operates based on a planetary or spur gear system driven by a hydraulic motor or electric motor. Key principles include:

• Torque Conversion: The hydraulic motor’s high-speed, low-torque output is converted into low-speed, high-torque rotation.

• Slewing Bearing Integration: The gearbox meshes with the slewing ring’s internal/external gears to facilitate smooth rotation.

• Braking Mechanism: Often includes mechanical or hydraulic brakes to stabilize the excavator during stops.
