Workpiece plate speed chain conveyor line selection Nan: load speed material full analysis

Hey, have you also encountered this situation - want to upgrade the production line to a speed chain conveyor line, the results of a look at the parameter table: load, speed, material, multiplier ratio ... head are big? Don't panic! Today we will use the vernacular, the pile of terms broken up and crumbled to make it clear, to ensure that you can avoid the selection pit after reading!

​First of all, the whole understand: times the chain in the end is how to "times the speed"?​

Simply put, it relies on"The rollers are bigger than the rollers."The design is careful!
Chain rollers with small diameters (call it for exampled), the large diameter of the rollers of the work plate (call it, for example, theD). When the chain is moving at a speedV₁When moving, the rollers generate additional speed due to rotation.V₂ = (D/d) × V₁And guess what? And guess what? The actual speed of the work board spiked right up toV₁ + V₂The maximum speed of the chain can be up to3 times!

​give me a chestnut: The chain climbs 1 metre, and the work plate on the 3x chain can rush out 3 metres - this efficiency, no wonder the assembly line of the electronic factory loves to use it!

​Second, the first step in the selection: load capacity do not blindly!​

Choose light and the chain breaks, choose heavy and it's a waste of money...remember the three axes:

1. ​Figuring out who "weighs the scales" is​
   Not just counting cargo weight!Workpiece weight + maximum material weight + stacking pressureIt all has to be included. For example, if you're transporting car parts, a single plate carries 240kg, but 5 plates stacked together could be over 1000kg - the chain would have to be selected for the stacked load!
   Formula: Total Load (kg) = (weight of single workpiece + weight of pallet) x number of stacks

2. ​Material determines load-bearing ceiling​

   • ​nylon chain: Light load small prince (≤ 500kg), anti-static also cheap, common in electronic factory assembly line.
   • ​Steel ChainHeavy-duty carrier (≤4000kg), high-temperature resistant, engine production line depends on it.
   • ​Stainless steel chain: Specialised for food and medicine, corrosion-resistant and resistant to cleaning, expensive but worry-free!

3. ​Overload warning!​
   Don't believe in "almost OK"! A machine shop to save money with nylon chain to pull heavy parts, the results of the load over 30% after theFailure rate spikes 50%, enough money to fix the equipment to buy two steel chains...

​Third, the speed is not selected correctly, the production line is given in vain!​

​Higher speeds aren't better.--Depends on whether your work is "embroidery" or "bricklaying":

​lesson learnt through blood and tearsA factory is running a 3x speed of 20m/min on an assembly line, and the result is that the precision parts have too much inertia and are shifting wildly...Yield rate plummets 20%! It was later reduced to 12m/min + adding non-slip mats to fix it.

​Fourth, how to choose the chain material? Remember the "three look" principle!​

1. ​look at the environment​

   • High temperature workshop (painting, forging).Hardened alloy steel chain(600°C resistant)
   • Wet/dusty areas.Sealed rollers + dust cover"A food factory has tripled its life expectancy.
   • Clean room.Stainless steel chain + food grade grease​

2. ​Depends on the cost​
   Nylon chain unit price ≈ 60% for steel chain, but doubles the life of steel chain in heavy-duty scenarios-It doesn't hurt in the long run.!

3. ​Watching Maintenance​
   Want to Save? ChooseSelf-lubricating chain(5 years maintenance free), 30% more expensive than regular chain, but the labour saved paid for itself long ago!

​V. Personal view: 3 big pits often stepped on by novices!​

After ten years of automation, I've found that White loves to plant in these three places:

1. ​Blindly chasing high multipliers::
   3x speed sounds awesome, butHigh speed = high precision requirementsThe guideway straightness difference is more than 1mm/m? The guideway straightness difference is more than 1mm/m? Immediately jammed off the chain.
2. ​Neglect of "electrified" needs::
   To power up a tooling board for testing (e.g. circuit board inspection)?Conductive Wheel + Sliding Contact WireMust plan ahead! Post remodelling is laborious.
3. ​I missed the motor power.::
   Don't just count material friction!Chain idle resistanceCan account for 30% loads - a factory forgot to count this and the motor burned two...

​with dry goods: Quick formula for calculating the power of a motor
​Power (W) = [ (load torque + idle torque) × speed] ÷ transmission efficiency​
(Transmission efficiency based on 0.8, safety factor recommended 1.5 times)

​Sixth, the ultimate lazy technique: copying homework according to the case!​

Save time and avoid pitfalls by benchmarking directly against proven programmes:

• ​electronic factory: 2.5x speed nylon chain + anti-static work plate + speed 12m/min (refer to a mobile phone factory, efficiency ↑40%)
• ​Auto Parts Line: 3x speed steel chain + heavy-duty stopper + speed 8m/min (a gearbox line carrying 2 tonnes is as steady as an old dog)
• ​Food packaging: Stainless steel chain + self-cleaning guide + 5 m/min low speed (daily capacity 500,000 bottles without jamming)

​One final word.: Selection of don't light ratio parameters! When looking for a supplierDead Reckoning Test Video, asked for a test run with 1.2x load - after all, drawings can brag, spinning chains don't lie!
