Hangzhou Ring Multiplier Chain Customisation: A Smart Engine for Closed Loop Speed Increase

在杭州制造业智能化转型的浪潮中，​​环形倍速链系统​is quietly reconfiguring the spatial logic of the factory. This seemingly simple design of a closed-loop track through theTriple physical speed increasetogether withthree-dimensional reflow structure​，不仅解决了传统流水线30%的空载回程痛点，更成为电子、家电等产业效率跃迁的隐形推手。杭州企业正借此在”多品种、小批量”的竞争格局中，实现效率与弹性的双重突围。

​​​I. Core technology: the physical code of differential motion​​​

of a circular multiplier chainClosed-loop uninterrupted conveyingIt is the core of its difference from the traditional assembly line. The essence of its speed increase stems from the diameter ratio of the roller (D) to the roller (d), following the physical formula:

​Material velocity V = (1 + D/d) × chain speed v₀​
When using a triple speed chain (D/d=3), the actual speed of the work plate can be up to 4 times the speed of the chain.

然而，杭州企业的实践表明：​Theoretical growth rates need to be compromised for engineering effectiveness. Example:

  • ​Compromise of reloading scenarios: The automotive parts production line needs to reduce the speed increase ratio (D/d ≤ 2) and use steel reinforced rollers (single point load 3.92kN), sacrificing speed for structural strength;
  • ​Correction for hot and humid environments​：杭州年均湿度75%，滚轮摩擦系数增加，实际增速仅为理论值的82%~85%。
