Robot arm 5-Axis zero backlash 1:80 ratio gear reducer harmoic drive gearbox CSG series

• ◈ Compact design
• ◈ High torque capacity
• ◈ Zero backlash
• ◈ Excellent positioning accuracy and rotation accuracy
• ◈ Input and output are coaxial

CSG harmonic reducer is used for high torque cases, its torque is 30% higher than CSF reducer’s, and the life time is 43% longer (10,000 hours).

CSG/CSF-2UH series harmonic drive units are available in ten sizes with gear ratios of 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 23 to 3419 Nm. The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support and thus permits simple and space saving designs.

Standard servo motors can be attached in a compact manner. The harmonic drive gearboxes cover a wide torque range and feature long service life, confirmed by many years of successful service. Unit and motor together form a compact and lightweight system capable of quickly withstanding high loads. Due to the Units positioning accuracy, stable machine characteristics with short cycle times are guaranteed.

CSG&CSF combination harmonic gearboxes are mainly structured by component sets. The cross roller bearing inside the harmonic drive is with high precision and high rigidity, it is used for holding (main bearing) external loading.
