Overview
The SITO DRIVE CS-17-I reducer is offered in 30, 50, 80, and 100 transmission ratios for listed robotic applications including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. Ratio selection changes the published torque and backlash values, while all options list a 7,300 rpm maximum allowable input speed, 3,500 rpm allowable average speed, and 0.079 (×10⁻⁴ kg·m²) moment of inertia.
Features
- Four selectable transmission ratios: 30, 50, 80, and 100.
- Published rated torque at 2,000 rpm input ranges from 8.8 to 24 Nm, depending on ratio.
- Published backlash is ≤20 arcsec for ratios 30 and 50, and ≤10 arcsec for ratios 80 and 100.
