Belt Conveyor Technical Datasheet

Vention's belt conveyor series, powered by Dorner Mfg. Corp. allows users to choose from a wide veriety of general purpose conveyors. Models are available in 4 different widths and 15 lengths from 585mm to 3240mm for a total of 60 different size options. Conveyors widths 152mm and 305mm come as a single, pre-assembled part. Conveyors widths 457mm and 610mm come as multiple parts and will require some assembly. The conveyors are compatible with all of Vention's NEMA 34 powertrain components allowing for even more customization.

Overview

Use this technical document to guide your selection of belt conveyor size, power transmission options, to ensure that you buy the correct combination of components for your application. This document will outline how to calculate the required forces to transfer your goods as well as the corresponding powertrain combinations to meet those requirements.


Applications

Applications for belt conveyors are diverse, but at their core a belt conveyor is always used to move an object from position A to position B. Applications vary from simple conveying systems to complex pick and place systems with indexing and part accumulation. Check out our design library for inspiration.

Displacement Ratio (mm/turn) 69.12 69.12

* Note: the rated load of the conveyor is not the same in both directions because of the end drive configuration. The belt can move a larger payload when it is moving the payload towards the motor (pulling) compared to when the payload is moving away from the motor (pushing).

Above ratings for maximum payload are calculated at equilibrium and assume a horizontal conveyor. The limiting factor is slip between the belt and conveyor pulley. To determine the correct powertrain for more complex applications that include accelerations and inclines see Calculating Required Driving Force

Suggested Mounting

Optimal conveyor mounting depends on the payload as well as the width and length of the conveyor. The following table can be used as a conservative guide. The mounting points should be spaced as evenly as possible. The number in the light blue section corresponding to the length and width of your conveyor indicates the suggested number of brackets to be used.

Length (mm) Width (mm)
From To 152 305 457 610
585 1305 4 4 4 4
1530 2070 4 4 4 6
2295 2655 6 6 6 8
2835 3240 6 6 8 8

Calculation Required Driving Force

To calculate the required linear force to drive your payload a few things must be considered. Main considerations are the desired acceleration of the belt when starting, the force required to deform the belt over the rollers, if the belt is on an incline or not, and what the friction generated by the payload is. The sum of these four forces will give the required linear force of the belt conveyor.


dorner conveyor equations


The deformation force for each conveyor width is provided in the table below. This value represents the torque and equivalent force required to deform the belt over the conveyor rollers. The value also includes other small parasitic losses in the system.

Belt Width (mm) Deformation Force (N)
152 56.5
305 98.9
457 120
610 141

After the required driving force has been calculated, compare it to the force vs speed graph below. We also recommend using a safety factor of 1.2 in your calculation to ensure that there is no risk of overloading the motor.

As an example, a conveyor needs to move a load of 30 kg at 1.5m/s up a 20 degree incline. The conveyor must occasionally be able to accelerate the mass at 0.5m/s^2. The width of the belt conveyor is 457mm.

In this case our variables are 30kg for mass, 0.5m/s^2 for acceleration, 20 degrees for angle theta, and 120N for deformation force. These variables lead to a required driving force of 326.9N. Applying a safety factor of 1.2 the new required force is 392.3N at 1.5m/s. Looking at the Force vs speed graph below it can be seen that the MO-SM-001-0001 motor will be required to meet these requirements.

Once the motor type has been selected based on required force and speed you can add the appropriate part to your design.

Assembly Instructions

  1. Assemble the vention extrusion frame
  2. If a 457mm or 610mm wide conveyor was ordered, follow the assembly instructions included in the package from Dorner.
  3. Install the Vention Belt Conveyor Mounting Brackets to the T-slot on the Dorner Conveyor using the included T-bar and M6 fasteners. Tighten finger tight only.

  4. Mount the conveyor onto the extrusion frame and connect the brackets to the extrusions using the included M8 fasteners. Once the conveyor is mounted in place, tighten the brackets which connect to the conveyor.

  5. Install your Vention NEMA 34 motor to the input shaft of the belt conveyor motor mount.

  6. Install the Vention compatible motor mount to the Dorner conveyor input shaft. The below images show the installation process provided by Dorner. Motor and mounting features will vary from the images below as the motor mount provided by Vention is a specialized model.
    1. The following image shows the contents of the motor mount kit.

      2. Driven pulley with 12mm bore
      3. Timing Belt
      4. Key for the driven pulley
      5. M6 fasteners used for mounting the motor mount
      6. M6 fasteners used to install a Vention motor to the motor mount

    2. Attach the motor mount (1) to the conveyor by removing the two countersunk M6 screws in the conveyor end plate, placing the motor mount over the plate, and re-installing the motor mount with the supplied longer M6 fasteners (5).

    3. The motor mount and conveyor should look like this once the new fasteners are installed:


    4. Install the key into the keyway of the conveyor shaft, then slide the driven pulley onto the shaft and tighten the set screws to fix it in place. Ensure that the pulley is in-line with the idler and driving pulley so that the belt will track straight.


    5. Using the idler, apply tension to the belt so that the belt is tight enough so that 4.5N of force will cause the long section of the belt to deflect 3mm. Note the tensioner position should be driven by the main direction of travel of the conveyor. The idler should be on the side of the belt with higer tension.

    6. Install the sheetmetal cover using the 4x M4 fasteners.
