Overview
The SITO DRIVE HD-17 Pro Reducer is offered in 50 and 100 transmission-ratio options for robotic systems, including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. The ratio selected changes the rated, peak, average-load, and instantaneous torque values, as well as backlash. Both options support up to 7000 rpm input speed and 3500 rpm allowable average speed.
Features
- HD-17 Pro reducer with selectable 50 or 100 transmission ratio.
- Maximum allowable input speed of 7000 rpm for both ratio options.
- Allowable average speed of 3500 rpm and moment of inertia of 0.09 × 10-4 kg·m² for both ratio options.
