Harmonic Drive CSF-14 is a three-component set (component set) of the CSF-2A strain wave gear series by Harmonic Drive LLC, size 14 (cup type). The set includes: wave generator (WG), flexspline (FS, cup), and circular spline (CS). The cup type is the most classical geometry with a thin-walled cup-shaped flexspline featuring external teeth at the open end.
Available ratios: 50:1, 80:1, 100:1, 120:1, 160:1. Peak torque: 16 Nm (at 100:1), continuous 5.4 Nm. Angular backlash: <=1 arc-min. Max input speed: 8500 rpm (ratio 100). Total set weight approx. 0.12 kg. Operating temperature: -10 to +70 degrees C.
CSF is the most widely used Harmonic Drive series in educational robotics, cobot arms, haptic systems, and research equipment. Low flexspline moment of inertia ensures fast dynamic response. Available in 2A version (standard) with full designer documentation.
Harmonic Drive · serves as: Gear Reduction, Torque Transmission, Precision Joint Motion, Joint Actuation.
Which group Harmonic Drive CSF-14 belongs to and how it is built
This subcategory covers components responsible for highly accurate torque transmission and speed reduction in robots, manipulators, and joint modules.
Harmonic Drive is a specialized strain wave gear valued in robotics for its high precision, very low backlash, and large gear reduction ratio in a compact form factor. It is widely used in the joints of industrial and humanoid robots, as well as manipulators with demanding accuracy requirements. Its compact construction enables the design of rigid, precise motion axes.
