The DHSG-H Series represents a high-performance harmonic reducer platform designed for precision robotic joints and industrial automation systems. Its optimized transmission structure combines accurate positioning, low hysteresis loss, and strong torsional stiffness to support demanding motion requirements. With transmission accuracy reaching 30 arcsec for reduction ratios above 50 and hysteresis loss as low as 1 arcmin, the series provides stable and repeatable motion performance for advanced robotic applications.
Optimized harmonic transmission structure improves positioning accuracy and achieves transmission accuracy down to 30 arcsec.
Reduced elastic deformation minimizes motion deviation and achieves hysteresis loss as low as 1 arcmin.
Enhanced structural stiffness provides T1/T2 rigidity performance for stable robotic motion control.
The DHSG-H Series covers sizes 14, 17, 20, 25, 32, 40, and 45, with reduction ratios from 50 to 160. The following specifications are based on available technical data.
