Step 2. Select the chain specifications

2-1. Chain specification selection

Refer to Table 1 to select the appropriate top plate material based on the material of the transported item.

Note)

  • 1. "A": Highly recommended, "B": Recommended, "C": Recommended among acceptable, "D": Acceptable, "×": Inappropriate.
  • 2. If antibacterial and antifungal performance is required on food and beverage conveying lines, select the antibacterial and antifungal (MWS) specification.
  • 3. This includes beer cans, soft drink cans, and cans with metal lids and bottoms and fiber sides.
  • 4. Includes plastic, plastic-coated and paper containers for dairy products such as milk, cheese and ice cream, confectionery, etc., as well as paper board or paper-bottom products such as soap and cereals.
  • 5. Includes glass bottles and glass containers used for alcohol, food, pharmaceuticals, cosmetics, etc.
  • 6. Includes machine parts, molds, castings, forgings, metal, bearings, bolts, nuts, etc.

2-2. Selecting the top plate width

Generally, the width of the top plate is selected to be slightly larger than the width of the transported item.

If the width of the conveyed item is large and there is no top plate width that is sufficient, multiple strand of chains of the same width are used. Although multiple strand strands of chains of different widths can be used, this is not recommended as the tension acting on the chain will be uneven.

You can also use Plastic modular chain.

・Top plate end face shape of cut product

The top of the cut end face is chamfered to approximately C0.5 to 0.8, and the four corners are chamfered to approximately C2.

  • 3. Special end face shapes can also be processed upon consultation.
  • 4. If the top plate width is small, the chamfering may differ.
  • 5. Because the top plate width is machined, the main chain stamping and format will differ.

Note)

  • 1. Lubrication is recommended for curved conveyors where the chain and wearstrip slide against each other. Particularly for curved conveyors with a sideways angle of more than 90°, the chain or wearstrip may wear unevenly in a relatively short period of time, which may cause the chain to lift up. If lubrication is not possible, consider using corner discs to prevent sideways bending.
  • 2. The heat resistance and high speed (KV) specifications are for normal temperatures. At high temperatures (over 50°C), please apply the values for steel or stainless steel without lubrication or with water lubrication.
  • 3. Applicable to: Standard Series, Chemical resistant (Y), Conductive (E), Impact resistant (DIY), Metal detectable (MPW), UV resistant (UVR), and Plastic Crescent Chain.
  • 4. Applicable: Low Friction / Anti-Wear (LFW, LFG, LFB) specifications, low friction (NLF, WR) specifications, Low Friction / Anti-Wear (HG) specifications, antibacterial and anti-fungal (MWS) specifications.

Step 5. Calculate chain tension and power requirements

5-1. Calculation of F for straight running

Calculation of F for straight running

Note: SI units and gravity units
The formula is written in both SI units and gravity units. When calculating tension F in gravity units, weight in gravity units (kgf) is the same value as mass in SI units (kg).

Explanation of symbols

  • F = tension acting on the chain kN{kgf}
  • m1 = Approximate chain mass (kg/m)
  • L = length of conveying section (m)
  • m2 = mass of material conveyed through the conveying section (kg/m)
  • L' = Length of the accumulation section (m)
  • m3 = Mass of material conveyed in the accumulator (kg/m)
  • μ1 = Coefficient of dynamic friction between the chain and wearstrip (see Table 3)
  • μ2 = Dynamic friction coefficient between the chain and the conveyed object in the accumulation section (see Table 3)
  • μ3 = Coefficient of rolling friction between Plastic Roller and the conveyed object (see Table 4)
  • αL = angle factor when using wearstrip (see Table 5)
  • αC = angle factor when using corner discs (see Table 6)
  • αS = length factor (see Table 5)
  • θ = tilt angle (degrees)
  • r = radius of lateral bending (m)
  • P = required power (kW)
  • V = Chain speed (m/min)
  • ηNote) = Mechanical transmission efficiency of the drive unit

Note: Please check the drive unit used to determine transmission mechanical efficiency.

SI units (kN)

Tension acting on the chain

F = 9.80665 × 10-3 { (2.1m1 + m2) L・μ1 + (2.1m1 + m3) L'・μ1 + m3・L'・μ2 }

Required power

P = F・V 60η

Gravity unit (kgf)

Tension acting on the chain

F = (2.1m1 + m2) L・μ1 + (2.1m1 + m3) L'・μ1 + m3・L'・μ2

Required power

P = F・V 6120η

Note: When using an accumulation chain (TTPDH-LBP type, etc.), μ2 of μ3 Please change it to and calculate.

5-2. Calculation of F for curved conveyance (one curved section)

Basically, it is the same as for straight running. The tension acting on the corners is corrected by the angle coefficient.

An example calculation is shown for the conveying route in the diagram below. Lubrication is recommended for curved conveyance where the chain and wearstrip slide. In particular, when the lateral bending angle exceeds 90°, the chain or wearstrip may wear unevenly in a relatively short period of time, and the chain may lift off. If lubrication is not possible, consider using corner discs to prevent lateral bending.

Note

  • 1. When using a curved accumulation chain (such as TPUS-LBP type), μ2 of μ3 Please change it to and calculate.
  • 2. When using a corner disc in the corner section, use the corner disc angle coefficient αC instead of the angle coefficient αL.

5-3. Calculation of F for curved conveyance (two curved sections)

When sliding wearstrip or other device on a curved section, limit the number of 90-degree curves to two, as this may cause chain pulsation.

If you want to install more curved sections, consider dividing the conveyor or using a corner disc.

Note

  • 1. When using a curved accumulation chain (such as TPUS-LBP type), μ2 of μ3 Please change it to and calculate.
  • 2. When using a corner disc in the corner section, use the corner disc angle coefficient αC instead of the angle coefficient αL.

5-4. Calculation of F for curved conveyance (horizontal drive)

Applicable chain TPUH-BO type (for horizontal transport),
Plastic Crescent Chain (TORP type, TOSP type),
Stainless steel Top chain (TO type, TU type)

Basically, it is the same as for straight running. The tension acting on the corners is corrected by the angle coefficient.

A calculation example is shown for the transport route shown below.

Transport route

F = 9.80665 × 10-3  ・FC (kN)

5-5. Calculation of F for TTUP(T)-M type and TTUPM838H type curved conveyance (one curved section)

The coefficients in Table 7 are based on our internal experimental data. Differences may occur depending on the conditions of use, the shape and material (specifications) of the transported items.

Use each coefficient for tension calculations.

5-6. Calculation of F for inclined conveyance

It is difficult to accurately determine the angle of the tilt limit due to the influence of speed, transported object, center of gravity, mass, conditions, etc.

Table 8 shows a guideline, but testing is required.

Back to Top

Step 6. Determine the chain format

Select Top chain with Maximum allowable load greater than the tension (F) acting on the chain.

Calculate Maximum allowable load by referring to Allowable load graph and taking into account the conveyor speed and ambient temperature.

Please refer to each product page for Allowable load graph.

F ≦ Maximum allowable load (taking into account speed and temperature)

If Maximum allowable load is insufficient, you can narrow the top plate width and increase the number of chains, or connect a shorter conveyor.

Alternatively, choose a chain with a higher Maximum allowable load.

Please also consider the environment in which the conveyor will be used when deciding on the chain type.

  • Note 2: ULF series had discontinued since October 2018.
■ Protection of transported items
This is our original material developed by blending a silicone-based lubricant for the purpose of dry conveyance.While maintaining the same friction coefficient as the previous ULF specification, it significantly reduces the amount of Wear debris generated under unlubricated conditions.
■ Smooth branching and collection of transported items
■ Reduction in power requirements
■ Comparison of wear with the old ULF specification
65%down
  • *The graph above shows the results of our internal testing. The wear volume of the old ULF specification is set as 100 (standard).
