Product Overview
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.
CSG & CSF series combination harmonic gearbox can meet the request of high function, high speed, high load capacity, high density, subtle and accelerate the demand of the technical innovation, realize the rich product lineup, make the customer can according to their own situation to choose the best model.
Difference between CSG series and CSF series is that CSF series harmonic gearbox is with standard torque, while CSG series harmonic gearbox is with more higher torque and longer service time.
