Crane Ring Gear
The ring gear is a large-diameter gear ring typically used in slewing and hoisting mechanisms of cranes. It is an essential part of the slew drive system, allowing the crane to rotate under load.
Features:
- Made from hardened alloy steel or forged steel
- Internal or external teeth options available
- Precision machined for smooth rotational movement
- Ideal for heavy-duty load-bearing applications
Applications:
- Tower cranes, mobile cranes, slewing cranes
- Wind turbine systems
- Construction and port equipment
Crane Part: Planetary Gearbox
The planetary gearbox is a compact, high-torque transmission system used in crane hoisting, trolley, and slewing drives. It offers higher efficiency and load distribution compared to conventional gear systems.
Key Benefits:
- High torque-to-weight ratio
- Compact design with multiple gear stages
- Low backlash and high load capacity
- Enhanced operational efficiency and long service life
Common Uses:
- Hoist mechanisms
- Boom rotation
- Winch drives in gantry and crawler cranes
Sun Gear (Crane Part)
The sun gear is the central gear in a planetary gearbox. It transmits motion to planetary gears and plays a crucial role in distributing load evenly across the system.
Highlights:
- Manufactured from heat-treated alloy steel
- Precision-ground teeth for optimal meshing
- High resistance to wear, torque, and stress
- Ensures smooth and synchronized gear operation
Function:
- Works with ring and planetary gears in compact gearboxes
- Maintains balance and even torque distribution in cranes
