A torque limiter
The torque limiter addresses the inefficiencies of existing systems by using a coupling shaft with spherical ball grooves and a cage structure to manage peak torques, ensuring quiet operation and easy maintenance, thus preventing damage and reducing costs.

AI Technical Summary
Existing torque limiters in cardan shafts and drivetrains are costly, complex, and ineffective in quickly responding to sudden peak torques, leading to damage, noise, and vibration issues, with difficult maintenance and high replacement costs.
A torque limiter with a coupling shaft, spherical ball grooves, flat portions, and a cage structure that allows balls to move radially and axially, using belleville/disc springs to manage torque, preventing damage by disengaging when peak torque occurs, and reducing noise and vibration through optimized groove geometry.
The torque limiter effectively prevents damage from sudden peak torques, reduces noise and vibration, facilitates easy maintenance, and lowers replacement costs by allowing disassembly and assembly without a monoblock structure.
