Triple Double Layer Speed Chain: A New Era of Space Folding and Intelligent Conveying

▍核心原理：物理增速与空间复用的协同进化

三倍双层倍速链系统的本质是​​差速效应与垂直循环的深度融合​​。其核心在于通过滚轮（直径D）与滚子（直径d）的直径差异实现工装板增速，遵循公式 ​Vtooling board
= Vsprockets
× (1 + D/d)​。当滚轮直径为滚子的2倍（D=2d）时，工装板速度可达链条速度的3倍。这一设计突破传统单层输送局限：

三倍双层倍速链

  • ​upper chain of production​以3倍速输送载物工装板，速度可达20米/分钟；
  • ​​下层空板回流​Save 58% horizontal space by forming a closed loop between the load shifter and the jacking mechanism;
  • ​Vertical Circulation Module​实现”输送-回流”无缝衔接，避免传统产线工装板离线周转的耗时问题。

​personal viewpoint​：三倍速不仅是速度提升，更是生产时空的拓扑重构。例如在新能源电池模组产线中，该结构使单日产能提升35%，印证了”速度×空间”的协同效应对制造密度的革命性影响。

Dynamic power regulation through torque coupling algorithms:

make a copy of
ΔT = K × (V theoretical - V measured) × D / (9550 × η)  


(K = 1.2-1.5 attenuation factor, D roller diameter, η transmission efficiency)
