"Family Head, there's a big problem now. We've solved the power issue, but we can't resolve the transmission system." An old craftsman, somewhat collapsing, said to Lul Jun. The model and reality are still different, and while all other issues have been resolved, the transmission is completely unsolvable, with potential damage skyrocketing.
The gears in the mechanical transmission device pose a significant problem. The meshing performance is a crucial component, and likewise, the bearings are also very important.
The issue is that the former can barely be solved, albeit with great difficulty. As for the latter, can anyone tell me how to make a sufficiently round metal ball, and in large quantities of identical size? It's simply impossible. We didn't consider the transmission in the model before, and now it's turned out to be an indispensable part in real construction.
