Dalian Ring Doubling Chain: Time Folders for Smart Factories

​A subtle microcosm of industrial civilisationThe laws of physics and the wisdom of manufacturing conspire for efficiency in the Dalian factory's circular speed multiplier chain as the workpiece slides across the track at 2.5 times the speed of the chain.

​I. Physical innovation of differential chain: the mechanical code of ring speed increase​

At the heart of the Dalian Ring Speed Chain lies theDesign of roller to roller diameter ratio--While the chain is running at base speed, the workpiece can speed up to 2.5 times. This phenomenon followsVelocity jump equation::

• ​V_{tooling board}
  = V_sprockets
  × (1 + D/d): Theoretical 2.5 times speed is achieved when the roller diameter (D) is 1.5 times the roller diameter (d);
• ​Friction Compensation TechnologyHigh-precision engineering plastic rollers with graphene-coated guide rails press the actual sliding rate to ≤5%, offsetting friction loss;
• ​Ring closure structure: Side plate pin connection for seamless closed loop and 30% traction increase, solving the problem of traditional chain shaking.

​Second, the Dalian industrial adaptation programme: three major scenarios of the attack on the actual record​

Pain point attack:
  - Engine block transport jitter > 0.1mm (precision assembly failure)
  - Conventional steel chain noise >85dB (risk of hearing damage in workshop)
Customised solution:

  - A gearbox production line in Dalian, the failure and downtime rate decreased by 60%, saving 900,000 yuan in annual maintenance costs.  
​2. Appliance assembly - time-folding techniques for flexible manufacturing​

​spatial reconstruction::

The height of the 12-metre circular line body is compressed to 1.8 metres (40% lower than the double-deck structure), suitable for dense plants in Dalian;
The spacing of workstations is 1.2 metres in golden section, and the 5-metre straight section accommodates 4 operating positions.
