At Shenzhen Shan Chuan Harmonic Drive Technology Co., Ltd., we pride ourselves on our robotic joints, which are meticulously designed to deliver high torque at low speeds through a precision misalignment movement. Our harmonic drive gear reducers are the epitome of engineering excellence, consisting of a wave generator, a flexspline, and a circular spline. These reducers are categorized based on the number of mechanical waves they generate, with single-wave, double-wave, and triple-wave transmissions available. The double-wave transmission is the most prevalent, featuring a two-tooth difference between the flexspline and the circular spline. This design ensures that for every full turn of the wave generator, the flexspline moves back two teeth in the opposite direction of rotation, providing smooth and efficient motion.
Our harmonic drive reducers are recognized for their compact design, lightweight construction, large transmission ratios, high load capacity, precise transmission, and remarkable efficiency. These attributes make them indispensable in a variety of sectors, including robotics, CNC machinery, photovoltaic systems, medical equipment, semiconductor machinery, and aerospace. In the realm of robotics, they are particularly crucial, serving to reduce output speed and increase output torque in joint drive systems. This enhancement in performance significantly boosts the robots' gripping precision and load-bearing capabilities.
The durability of our harmonic drive reducers is paramount, with failures often stemming from fatigue fractures in the flexspline or damage to the flexible bearing, both of which undergo elastic deformation during operation. A detailed analysis of the components reveals the following:
- Flexspline: The material purity is critical for fatigue performance, with 40Cr alloy steel being the standard. Ensuring material quality often requires reliance on imports. The gear tooth profile significantly impacts transmission performance, with careful design necessary to prevent premature failure. Heat treatment processes must be tailored to the specific material, and precision machining relies on high-end, often imported, equipment.
- Flexible Bearing: Fine-tuning the micro-alloy element ratios and heat treatment processes can enhance the bearing's impact resistance and extend its service life.
Harmonic reducers play a pivotal role in industrial robots, with labor shortages and increasing labor costs driving demand. The positive outlook for downstream industries is expected to fuel continuous growth in the industrial robot sector.
Tesla's foray into the humanoid robot market has accelerated the industrialization process, with the potential to unlock a new market worth billions. As Tesla Optimus and other leaders push the boundaries, and with supportive policies in place, 2024 is poised to be a milestone year for the mass production of humanoid robots. The global market for harmonic gear drive reducers in humanoid robots is projected to grow exponentially, from 20 million in 2024 to an estimated 26.74 billion by 2030.
While there may be minor differences in product parameters such as torque, backlash, and hysteresis loss, Shenzhen Shan Chuan's harmonic reducers offer a higher cost-performance ratio and significant cost advantages. With ongoing investments in high-end product capacities, we are well-positioned to increase our domestic market share and break foreign monopolies in the future.
