Schaeffler has successfully validated a new manufacturing process for formed strain wave gearboxes, which significantly reduces production costs and time. This innovation is crucial for humanoid robotics, where actuators can account for up to half of a robot's total manufacturing cost. With mass production planned for 2027, Schaeffler aims to solidify its position as a leading Tier 1 supplier in the humanoid robotics market.
The formed strain wave gearboxes offer advantages over traditional planetary gears, including zero backlash and high precision in a compact design, essential for robotic joints. The new manufacturing method utilizes high pressing forces to shape components quickly, cutting costs by over 25% and reducing material use by more than 75%. This advancement addresses a significant supply chain challenge as humanoid companies scale production from hundreds to thousands of units.
Looking ahead, Schaeffler's formed strain wave gearboxes complement its existing planetary gear actuator solutions, enabling the company to provide a comprehensive range of actuation products for OEM robot manufacturers. No further timeline was disclosed at the time of publication.
