A planetary gearbox consists of:
Sun Gear (center gear)
Planet Gears (multiple gears revolving around the sun gear)
Ring Gear (outer internal gear)
Planet Carrier (holds the planet gears)
This design allows the load to be distributed across multiple gears simultaneously, resulting in higher torque capacity, better efficiency, and compact dimensions compared to conventional gearboxes.
Key Features of WANSHSIN Planetary Gearbox
1. High Torque Output
The planetary gear arrangement distributes load among multiple gears, enabling the gearbox to transmit high torque while maintaining a compact size. WANSHSIN's spiral bevel gear designs can deliver significantly higher torque capacity than conventional straight bevel gear designs.
2. Low Backlash
WANSHSIN planetary gearboxes are designed for precision motion control with minimal backlash, making them suitable for servo motor and CNC applications where positioning accuracy is critical.
3. High Rigidity
The integrated planet carrier and output shaft construction provides excellent torsional rigidity, improving positioning accuracy and system stability.
4. High Efficiency
Planetary gearboxes generally achieve efficiencies around 95%, resulting in lower energy losses and improved machine performance.
5. Compact Design
Despite delivering high torque, the planetary gear arrangement allows for a smaller footprint, making it ideal for space-constrained automation systems.
6. Low Noise Operation
Optimized tooth profiles and precision gear manufacturing reduce vibration and operating noise levels.
