Overview

The SITO DRIVE HS-14-III reducer is offered in 30:1, 50:1, 80:1, and 100:1 transmission-ratio options for robotic motion systems. At a 2000 r/min input, rated torque ranges from 4 to 7.8 Nm by ratio, while permitted start/stop peak torque ranges from 9 to 28 Nm. Compare the selected ratio with the torque, backlash, and speed limits below for the intended motion axis.

Features

Four selectable transmission ratios: 30:1, 50:1, 80:1, and 100:1.
Maximum allowable input speed of 8500 rpm and allowable average speed of 3500 rpm for every listed ratio.
Backlash of ≤20 arcsec for 30:1 and 50:1 options, and ≤10 arcsec for 80:1 and 100:1 options.

Applications

Humanoid robots and robotic arms: select a ratio and its corresponding rated, average-load, and start/stop torque limits for a motion axis.
Exoskeletons and quadruped robots: use the listed ratio-specific backlash and speed limits when assessing motion-transmission requirements.
AGV vehicles and ARU robots: compare the selected ratio with the allowable input and average speed ratings for the intended drive system.
