Harmonic Drive SHG-2A Silk-Hat Strain Wave Precision Component Set
Vendor: Harmonic Drive
Product: SHG-2A （ /Silk-Hat）
Harmonic Drive is the inventor and global leader of strain wave (harmonic) gearing. The SHG-2A silk-hat component set (wave generator, flexspline, circular spline, output flange) is axially shorter than the cup-type CSG, spanning 10 sizes 14-65 with ratios 50-160: rated torque (L10) 7-1,236 N·m, repeated peak 23-3,419 N·m, momentary peak 46-6,175 N·m, backdriving start torque only 2.2-180 N·m, standard accuracy 1 arcmin (1.5 for size 14), zero backlash, torsional stiffness K1 0.47-54 x10^4 N·m/rad at 0.11-7.04 kg - ideal for axially constrained precision joints in humanoid/cobot shoulders, elbows and wrists.
