Outline
Torque limiter is a physical protection device that ensures mechanical equipment operates under safe load conditions. Conventional engineering design typically employs static design and verification methods, with optimization and iteration carried out through physical prototypes, resulting in long development cycles and high costs. The design simulation and combination parameter optimization of a miniaturized torque limiter for a specific model are focused on. Firstly, based on the principle and elements of the steel ball's inclined surface disengagement, some mathematical formulas are established and a three-dimensional structure is designed, identifying the key parameters affecting the performance of the torque limiter. Secondly, the torque transmission characteristics and structural strength of the torque limiter are simulated, and the accuracy of some strength simulation results is verified by using Hertz contact theory. Thirdly, the main structural parameters are optimized and evaluated by using the orthogonal experiment method, obtaining the best parameter combination. Finally, two principle prototypes are produced based on the models before and after optimization, and static disengagement experiments are conducted to verify the accuracy of the disengagement torque under static load.
