Product Description
CSD 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.
CSD 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. CSD series combination harmonic gearbox can meet the request of high function, high speed, high load capacity, high density, subtle and accelerate the demand of technical innovation, realize the rich product lineup, making customers able to choose the best model according to their own situation.
Technical Characteristics
Our technical team realized the tooth shape optimization design through the big data theory modeling simulation optimization and performance verification, breaking the constraint of experience accumulation and correction in the transmission design. We are constantly seeking improvement and innovation in the technical performance, product structure, processing technology, materials and features of our harmonic drive.
Through long-term technical accumulation, the key technologies of our harmonic drive have reached the international level of similar products in product accuracy, longevity, stability, noise control, and the technical indicators are in the forefront.
Harmonic Reducer Performance
Widely used in industrial robots, medical equipment, precision instruments:
- High efficiency: Model 30-120, speed 100~3000 rpm, efficiency 75~90% when ratio 30~120; efficiency 70~85% when ratio 160.
- Low noise: At rated speed and load, the noise is less than 50dB.
- Long life: The life of the harmonic reducer is 10,000 hours.
- High precision: Less than 20 arc seconds.
- High transmission ratio: The transmission ratio of level 1 can reach i = 50 ~ 160.
Key Advantages:
