A typical slewing gearbox consists of:
Gears: Planetary gears, spur gears, or worm gears for torque multiplication.
Housing: Robust cast iron or steel casing to withstand heavy loads and environmental stress.
Input Shaft: Connects to the hydraulic motor.
Output Pinion: Engages with the slewing ring gear.
Bearings: Tapered or roller bearings to reduce friction.
Seals: Prevent lubricant leakage and contamination.
Brake Assembly: Disc or drum brakes for rotation control.
Rotation Control: Enables precise 360° excavator movement.
Load Distribution: Transfers operational loads (e.g., digging forces) to the undercarriage.
Shock Absorption: Mitigates impacts during sudden stops or uneven terrain.
Power Transmission: Efficiently transfers hydraulic/electric power to rotational motion.
