AI Technical Summary
Existing rotary actuators are difficult to implement fault protection in high transmission ratio applications, and traditional reduction ratios are small, making it difficult to meet the needs of high lift systems.
It adopts an integrated design of torque limiting mechanism and planetary reduction mechanism, including input ball track plate, output ball track plate, friction plate assembly and disc spring structure. The ball-and-socket structure converts torque into axial force to achieve fault protection, and the friction plate assembly brakes to avoid overload.
It achieves a large transmission ratio, strong load-bearing capacity, and fault protection function. It is suitable for high-lift systems in the aviation field, with a compact structure and easy to promote and apply.
