Overview
The SITO DRIVE HS-32-I reducer is offered in 50, 80, 100, and 120 speed-ratio options for robotic drive applications. At a 2000 r/min input speed, rated torque ranges from 76 to 137 Nm by ratio, while allowable backlash is ≤20 or ≤10 arcsec. Compare the ratio-specific torque limits and backlash values when selecting a configuration for humanoid robots, robotic arms, mobile robots, or other listed systems.
Applications
The listed application scenarios include humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. The available speed-ratio options and ratio-specific torque and backlash values provide selection data for robotic drive mechanisms.
