AI Technical Summary
Traditional pulleys have a larger weight at the same tension and a smaller tension at the same weight, resulting in reduced performance and inability to fully play their role.
By setting a boss on the pulley limit plate and digging internal threads on its inner wall, and connecting with stainless steel screws, the volume of the stainless steel parts is reduced, thereby ensuring the tension value while reducing weight.
The effect of fully ensuring the tension value while reducing weight is achieved, and the performance of the pulley is improved.
