摘要

The drive (1), for underground mining equipment, has a gear assembly (2) with oil lubrication, and an overload clutch (3) which is switched by hydraulic pressure on an overload through a hydraulic line (5) and connection (4). The hydraulic fluid to switch the clutch is the gear lubricating oil. A common oil sump (8) provides oil for the gear lubrication circuit (9) and the hydraulic overload clutch circuit (10).
