Overview

The SITO DRIVE CD-20 reducer is offered in transmission ratios of 30, 50, 80, 100, and 120 for listed robotic applications, including humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. Ratio selection changes rated torque, allowable torque limits, and backlash; compare the table values under the stated input-speed conditions.

Features

Five selectable transmission ratios: 30, 50, 80, 100, and 120.
Maximum allowable input speed of 6500 rpm for every listed ratio.
Allowable average speed of 3500 rpm for every listed ratio.
Moment of inertia of 0.09 × 10⁻⁴ kg·m² for every listed ratio.

Applications

The CD-20 is listed for robotic motion applications where the selected transmission ratio and corresponding torque limits can be assessed for the design requirement:

Humanoid robots
Robotic arms
Exoskeletons
Quadruped robots
AGV vehicles
ARU robots
