What Is The Advantage of Gft Series Planetary Gearbox?
Engineering Design & Performance Advantages
1. Exceptional Torque Density
40% higher torque-to-weight ratio than peers (GFT32T3 achieves 520Nm/kg)
18CrNiMo7-6 carburized steel gears withstand 2,500MPa contact stress
2. Precision Transmission Control
Planetary gear set division error <0.02mm, achieving >95.5% efficiency
Optional dual planetary carrier reduces backlash to <3 arc-min (instrument-grade precision)
3. Extreme Condition Adaptability
Cold-start capability at -40°C (pre-filled with specialty synthetic grease)
IP69K rating withstands 150bar high-pressure washdown
Economic Benefits
