FBS-U-Ⅰ Type

FBS-U-Ⅰ Type

The FBS-U-Ⅰ Type represents a leap forward in harmonic drive technology, featuring the advanced FB Series Double Circular Spline design. Engineered for compact precision, this series utilizes a revolutionary multi-segment continuous curvature tooth profile.

This geometric optimization ensures superior meshing accuracy and significantly reduces relative sliding friction, making it an ideal choice for applications requiring longevity and stability in a compact footprint.

Key advantages of the FSS unit include:

  • Advanced Tooth Profile: Transforms traditional two-segment arcs into a multi-segment continuous curvature curve, ensuring optimal gear meshing and reducing friction.

  • Extended Durability: The optimized contact mechanics reduce the gear fatigue pitting area by over 30%, extending the continuous running-in service life to exceed 15,000 hours.

  • Thermal Efficiency: The low-friction design effectively mitigates heat generation, reducing operating temperature rise by 8-10℃, protecting lubricant integrity even in confined spaces.
