Applications in Robotics
Planetary roller screws play a pivotal role in humanoid robotics technology, serving as a key component for achieving high-precision, high-efficiency motion. Compared to traditional lead screws, planetary roller screws offer superior transmission accuracy, higher load-bearing capacity, and a longer service life, making them indispensable to humanoid robotics.
The unique structure of planetary roller screws enables smoother and more precise motion control. Power transmission occurs via a planetary motion mechanism between the internal rollers and the screw shaft; this design ensures excellent stability and accuracy even under heavy loads and high-speed operation. Furthermore, their low coefficient of friction and high transmission efficiency minimize energy loss and heat generation, thereby enhancing the operational efficiency and durability of humanoid robots.
