FS Series
FS cup type features a flexspline with external gear teeth in the shape of a cup. Available options include: standard, high-torque, ultra-flat, lightweight.
About FS Tooth Profile
We have made several upgrades to the traditional theoretical double-arc profile. The original two-curve continuous arc profile has been optimised into a multi-segment continuous arc with varying curvatures.
This ensures proper gear meshing in the reducer while reducing relative sliding friction, thereby mitiga ting the risk of grease failure caused by grease displacement.
Based on the 5-tooth design, the load capacity is increased by 15%, the temperature rise is reduced by 8–10°C, and the gear contact area affected by fatigue pitting is reduced by more than 30%. The continuous operating life now exceeds 15,000 hours, significantly improving the overall performance of the strain wave gearbox.
FS Series – Compact, Lightweight & High-Torque Harmonic Drive Solutions
The FS Series Harmonic Drives are engineered to deliver high precision, compact size, and exceptional reliability across a wide range of applications. Designed with an advanced cup-type unit-type and high-performance variants, the FS lineup offers solutions for environments with strict space and weight constraints, while also meeting demands for high torque, long service life, and easy installation.
Whether prioritising lightweight design, enhanced torque capacity, or high-rigidity performance, the FS Series provides flexible options tailored to modern robotics, automation, and motion control industries. This makes it an ideal choice for achieving efficient, durable, and space-saving gear solutions.
Laifual Tooth Engagement – Step-by-Step Improvement
- Torque capacity increases 15%-30%
- The temperature rise decreased by 8-10℃
- Minimise the tooth surface contact area prone to fatigue pitting
- Service life exceeds 15,000 hours
During development, the formation of the flex spline tooth profile can be defined by the radial displacement of the Wave generator. Different reduction ratios can be achieved by matching various tooth profiles, and the meshing backlash can be conveniently adjusted according to actual conditions, ensuring that the reducer operates in an optimal working state.
