The DCDF Series is a compact cup-type harmonic reducer optimized for applications where installation space and motion precision are critical.
Featuring a lightweight structure, stable transmission performance, and optimized rigidity characteristics, the DCDF Series provides accurate positioning and smooth motion control for robotic joints, collaborative robots, and automated mechanisms.
With transmission accuracy reaching 60 arcsec and hysteresis loss controlled to 1 arcmin, the series ensures repeatable operation in precision motion applications requiring compact integration and high reliability.
Optimized internal structure provides high reduction performance within a compact footprint, making it suitable for integrated robotic joints and limited installation spaces.
Low hysteresis loss and accurate harmonic transmission improve positioning repeatability and reduce motion deviation during continuous operation.
Reduced size and optimized mechanical structure support lightweight robot arms, collaborative robots, and compact automation equipment.
The DCDF Series covers sizes 14, 17, 20, 25, and 32, with reduction ratios from 50 to 160.
Specifications include transmission accuracy, hysteresis loss, and torsional stiffness parameters.
