The DHD-R Series is a compact harmonic reducer designed for robotic joints and precision automation systems requiring efficient integration and reliable motion performance. Its optimized structure balances lightweight design with transmission accuracy, low hysteresis loss, and stable torsional stiffness. With transmission accuracy reaching 60 arcsec and hysteresis loss as low as 1 arcmin, the series supports applications including collaborative robots, compact robotic mechanisms, and automated equipment requiring precise positioning.
Optimized mechanical structure reduces installation space while maintaining stable transmission performance for robotic applications.
Precision harmonic gear engagement minimizes positioning deviation and improves repeatability in dynamic motion systems.
Reinforced reducer structure provides T1/T2 stiffness for accurate load control and robotic movement stability.
The DHD-R Series includes sizes 14, 17, 20, 25, and 32, with reduction ratios from 50 to 160. The specifications cover transmission accuracy, hysteresis loss, and torsional stiffness parameters.
