90 Degree Jacking Rotary Speed Chain: Knot Analysis and Selection Guide

​I. Core value: Why do we need a 90-degree jacking rotary multiplier chain?​

In automated production lines, material steering and workstation connection are the key to efficiency bottlenecks. Conventional conveyor lines require additional equipment to achieve 90-degree steering, while jacking rotary speed chainIntegrated steering, jacking and conveying functionsIn addition, space compression and beat improvement are achieved through mechanical structure optimisation. For example, a steering mechanism in an automotive assembly line reduces the footprint of the machine by 30%, while avoiding downtime losses due to material collisions.

​II. Structural analysis: how do the core components work together?​

​1. Multiplier chain incremental units​

• ​Roller-roller construction: The ratio of roller diameter (d) to roller diameter (D) determines the effect of speed increase, the formula isv=(1+D/d)v₀(v is the work plate speed and v₀ is the chain speed).
• ​Typical Speed Ratio: 2.5x speed chain (D/d=1.5), 3x speed chain (D/d=2), engineered plastic rollers reduce noise to below 65dB.

​2. 90-degree jacking rotary module​

​ask and answer questions for oneself: How does 90 degree steering ensure accuracy?
Limit section and block rigid contact locking angle, proximity switch real-time detection of the position, failure of the travel switch triggered redundant protection, error control within ± 0.1 °.

​III. Selection guide: key parameters and calculation logic​

​1. Load capacity verification​

• ​Step 1: Calculate the weight of the conveyor per metre​
  ​WA = (W₁ + W₂) / PL​
  (W₁: workpiece weight, W₂: pallet weight, PL: pallet travelling distance)
• ​Step 2: Calibration of chain allowable loads​
  

  Chain type	Allowable load (kgf/m)	Applicable Scenarios
  WCHE3	30	Electronic Light Duty
  WCHE4	55	Appliance Medium Load
  WCHE5	75	Automotive Heavy Duty

​2. Tension and dynamic calculations​

• ​Maximum tension formula::
  ​T = g/1000 × [(Hw+Cw)L₁-fc + Aw-L₂-fa + (Aw+Cw)L₂-fr + 1.1Cw(L₁+L₂)-fc]​
  (g: acceleration due to gravity, fc=0.08, fa=0.1, fr=0.2)
• ​Motor power matching::
  ​P = (T × K₁ × K₂) × v / (60 × η)​
  (K₁: speed coefficient, K₂: load coefficient, η: transmission efficiency ≥0.9)

​ask and answer questions for oneself: How is the velocity coefficient K₁ taken?
If the speed of the chain v = 12m/min (genus 10)

​Fourth, application scenarios: how to match industry needs?​

​1. High-octane electronic assembly​

• ​demand (economics): Micro-component anti-vibration steering
• ​programme: 2.5 times speed chain + nylon roller, jacking height 80mm, steering time ≤2 seconds.

​2. Heavy vehicle component handling​

• ​demand (economics): Engine tray steering skid
• ​programme: WCHE5 steel chain + V-guide groove, tension redundancy design 30%.

​3. Clean environment for food packaging​

• ​demand (economics): Waterproof and corrosion resistant
• ​programme: Stainless steel chain plate + ultra-high polymer polyethylene guide rail, friction coefficient reduced to 0.1.

​V. Selection decision tree: four steps to lock in the best programme​

1. ​constant load→ Calculate the WA and select the chain type against the allowable load table;
2. ​test tension→ Calculate T by substituting the working condition parameters to satisfy T ≤ (allowable tension × K₁ × K₂)/2;
3. ​functionality→ Select the material (engineering plastic/stainless steel) according to the environment and the limit method according to the accuracy;
4. ​cost sth.→ Choose WCHE5 for heavy-duty scenarios to reduce maintenance frequency and WCHE3 for light-duty scenarios to control costs.

The final choice needs to be balancedEfficiency Gaintogether withlife-cycle cost--For example, although the 3x speed chain has a speed increase of 40%, the wear rate of the roller is 15% higher than that of the 2.5x speed chain, and it is recommended to sacrifice part of the speed for durability when starting and stopping the line body frequently.
