利用啮合原理和计算机仿真技术，通过齿高参数的优化，齿顶结构的改善，提出了一种新型高齿圆弧齿同步带． 理论分析和仿真结果验证了结构参数的正确性，从而实现了以直观的、更接近实际情况的手段对同步带进行加工前效果分析和参数优选，为同步带的研究提供了一种新思路． By using the principle of meshing and computer simulation, a new type of high tooth arc tooth timing belt is proposed through the optimization of tooth height parameters and the improvement of addendum structure. The theoretical analysis and simulation results verify the correctness of the structural parameters, so as to realize the preprocessing effect analysis and parameter optimization of the timing belt by means of an intuitive and more realistic approach, thus providing a new idea for the study of the timing belt.
