Overview

The SITO DRIVE HS-25-III reducer is offered in 30, 50, 80, 100, and 120 transmission-ratio options for robotic systems, including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. At a 2000 r/min input speed, rated torque varies by selected ratio from 27 to 67 Nm. Select the ratio according to the required torque, allowable load torque, and backlash specification.

Features

  • Five transmission-ratio options: 30, 50, 80, 100, and 120.
  • Maximum allowable input speed of 5600 rpm for every ratio option.
  • Allowable average speed of 3500 rpm for every ratio option.
  • Backlash of ≤20 arcsec for ratios 30 and 50; ≤10 arcsec for ratios 80, 100, and 120.

Applications

  • Humanoid robots and exoskeletons: select a ratio with the appropriate rated and allowable load torque for the joint or actuator requirement.
  • Robotic arms: use the ratio-specific backlash value when positioning precision is a selection consideration.
  • Quadruped robots, AGV vehicles, and ARU robots: select from the available ratio options based on the system's required reduction ratio and torque limits.
