The DHSG-S Series is a slim harmonic reducer designed for applications where compact dimensions and precise motion performance are critical. Its optimized structural design reduces installation space while maintaining high transmission accuracy, low hysteresis loss, and reliable torsional stiffness. With transmission accuracy reaching 30 arcsec and hysteresis loss controlled to 1 arcmin, the series supports lightweight robot joints, compact automation mechanisms, and precision motion systems requiring efficient integration.
Optimized reducer dimensions reduce installation space while supporting lightweight robotic and automation system designs.
Advanced harmonic gear structure delivers accurate positioning with transmission accuracy reaching 30 arcsec.
Reinforced mechanical structure provides stable T1/T2 torsional stiffness for precise dynamic motion control.
The DHSG-S Series covers sizes 14, 17, 20, 25, 32, 40, and 45, with reduction ratios from 50 to 160. Specifications include transmission accuracy, hysteresis loss, and torsional stiffness performance.
