地下採掘ローダー用遊星輪駆動ギアボックス

The planetary wheel drive gearbox is a compact, high-efficiency mechanical system integral to underground mining loaders, designed to transmit power from the engine or motor to the wheels with exceptional torque multiplication and speed reduction. Utilizing a planetary gear configuration comprising a central sun gear, orbiting planet gears, and an outer ring gear, this planetary gearbox excels in heavy-duty applications by providing robust load distribution and minimal backlash, ensuring reliable performance in confined, harsh underground environments. In underground mining loaders, such as load-haul-dump (LHD) vehicles, it supports critical functions like propulsion and maneuvering through rugged terrains, often featuring multi-stage planetary arrangements for enhanced durability and power density.
