How Do I Calculate Conveyor Belt Tension? (with pictures)
To calculate the conveyor belt tension accurately, start by collecting all the information that you need and enter it in a form You need to calculate the maximum amount of tension that you can put on the belt system, which you can figure out by using several specific formulasGenerally, depending on the load, an elongation at fitting in the range of approx 01 – 1% is adequate; a tension takeup range x of 1% of the belt length is therefore sufficient When assessing shaft loads please take into account the differing belt pulls in stationary and operational modes Guidelines for Calculation methods – conveyor beltsMeasure the span length P 2 At center of the span length apply a force F (using a belt tension gauge) perpendicular to the belt span, large enough to deflect the belt 1/64” for each 1“ of belt span, q So, for a 32” span, the deflection amount would be 32/64” or 1/2”proper belt tensioning BestorqL = Conveyor length in meters Conveyor length is approximately half of the total belt length g = Acceleration due to gravity = 981 m/sec2 mi = Load due to the idlers in Kg/mConveyor Belt Calculations Bright Hub EngineeringA photo of a similar but larger drive pulley assembly is shown at the end of this report 2 E Vector sum of force on bearings and keys We have two loads on the shaft due to the belt tensions Note that the power that can be transmitted to the belt is a function of the tension on the low side of the belt, the coefficient of friction and the wrap angle It is typical of conveyor system to have a Shaft Design conveyor drive pulley

Pulley width recommendations: The length of the conveyor belt The most reliable way to determine the length is to place markings on the side of the conveyor belt Measure the length at regular intervals until you return to the first mark Torque input to shaft by each drive assembly (equal with torque generated by belt tension) = (BT1 – BT2)/2 x Pulley Diameter /2 = 52,341 Nm; Pulley mass = 5,286 Kg; Reaction force at Bearing ASteps to Calculate Minimum Pulley Shaft DiameterThe modulus of elasticity can be used to calculate the tension force it exerts under a specific extension, where T = tension force λ = modulus of elasticity A = crosssectional area x = extension l = length (m) TENSION FORCE The minimum belt tensions for transmitting the pulley peripheral forces are calculated as follows, where Fu = minimum peripheral force C = coefficient C f Conveyor Belt EquationsJust remember that idlers do not change the output of the drive system They are used to provide tension or to route the belt Below is the basic formula, an example, and a Pulley Speed Calculator for your use Please remember that there are more factors in a good drive setup than just if the pulleys fit Ratio: RPM 1: D 1: RPM 2: D 2: RPM 1 = RPM of Driver RPM 2 = RPM of Driven D 1 Pulley and RPM Calculator Engineering Information To calculate the minimum number of drive sprockets for a conveyor system 1) Divide the drive tension (Td) by the maximum load per sprocket (see table) 2) Divide the belt width (B) in inches, by 6 and add 1 The larger of the two numbers is the minimum number of sprockets neededFLAT WIRE CONVEYOR BELT TECHNICAL MANUAL

Depending on the complexity and length of the belt conveyor, there will be at least two pulleys – one at either end of the belt (head and tail pulleys) Most belt conveyors will have additional pulleys for tensioning the belt in some form, and, depending on the mechanism and design of the tensioning system, there could be multiple pulleys A pulley is essentially a drum with a shaft that is A photo of a similar but larger drive pulley assembly is shown at the end of this report 2 E Vector sum of force on bearings and keys We have two loads on the shaft due to the belt tensions Note that the power that can be transmitted to the belt is a function of the tension on the low side of the belt, the coefficient of friction and the wrap angle It is typical of conveyor system to have a Shaft Design conveyor drive pulley89 Belt Tension Calculations W b =weight of belt in pounds per foot of belt length When the exact weight of the belt is not known, use average estimated belt weight (see Table 61) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t , K x , and K y , are used in calculations of three of the components of the effective belt tension, TBelt Conveyors for Bulk Materials Fifth Edition Chapter 6The tail pulley is located at the tail end of the conveyor and it turns freely Now a "belt" can be put around the pulleys The Drive Pulley turns and moves the belt around and around and around BUT it is dangerous to have the belt hang down under the conveyor bed So small rollers are put into the Conveyor Bed to hold up the belt These turn freely and just idle Basic Belt ConveyorsMeasure the span length P 2 At center of the span length apply a force F (using a belt tension gauge) perpendicular to the belt span, large enough to deflect the belt 1/64” for each 1“ of belt span, q So, for a 32” span, the deflection amount would be 32/64” or 1/2”proper belt tensioning Bestorq
