一种力矩限制机构及飞行器
The high integration of the torque limiting mechanism is achieved through the double-stage ball-and-socket structure on the ball track, which solves the problem of low integration without return function and achieves the effect of reducing parts and compact layout.

AI Technical Summary
Technical Problem
Existing torque limiting mechanisms, when adding a non-return function, have low integration, complex structure, many types and numbers of parts, and large weight and volume.
Method used
It adopts a two-stage ball-and-socket structure on the fairway disc, and integrates functions such as no return and torque limitation by using different ball-and-socket lift angles, thereby reducing the types and number of parts and improving the integration.
Benefits of technology
Within limited space and weight requirements, a high degree of integration between torque limiting and non-return functions was achieved, reducing the types and number of parts and resulting in a more compact layout.
