The slewing ring operates as a large-scale anti-friction bearing:
Rotation Mechanism: The excavator’s hydraulic motor drives a pinion gear that meshes with the slewing ring’s gear teeth, enabling rotation.
Load Distribution: Combines axial (vertical), radial (side), and moment (tilting) loads from digging forces.
Lubrication: Grease reduces friction between rolling elements and raceways, preventing metal-to-metal contact.
Key Physics:
Static load capacity: Up to 5,000 kN (for mining excavators).
Rotational speed: Typically 0–10 RPM.
