Wuhan Fanzhou Harmonic Drive Co., Ltd. focuses on the R&D, production, and sales of harmonic reducers for humanoid robots, committed to providing high-precision, long-life, high-torque core components for the industry. Building on nearly 30 years of precision-machining expertise from its parent company Fanzhou Precision, it has rapidly entered the humanoid robot track. Its harmonic reducers adopt a unique "F-type tooth" non-conjugate tooth profile combined with a special wave generator, reducing tooth-surface pitting area, increasing flexspline rigidity, and enabling higher torque. Precision forming processes replace traditional hot forging, producing uniform flexspline wall thickness with a fatigue life of 15,000 hours, while improving material utilization and lowering cost. Key indicators including precision, life, and torque density reach internationally advanced levels. The products are widely applicable in humanoid robotics, providing reliable power transmission for robot joints.
