PROPER SELECTION OF A CONVEYOR PULLEY When selecting a pulley for a belt conveyor application, specifications will be determined by addressing the following steps: STEP 1 The Face Length of the Conveyor Pulley STEP 2 The Anticipated Belt Tension of the Conveyor System STEP 3 The Outer Diameter & Shaft Diameter of the Conveyor Pulley
All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 = For the inclined conveyor, additional tensions are induced due
1) add the weight of all the moving pallets and anything they are carrying together to get a total weight (8,400 kg). 2) multiply this by mu1 (0.075), a suitable value according to the bearings used in the wheels. 3) this gives the drive force that needs to be provided by the belt drive unit (8,400*9.81*0.075 = 6,180 N).
Shell strength of conveyor belt pulleys 345 There is a maximum radial displacement Wmax at the shell centre of the axial section and there are two minimum radial displacements l'Vmin at the ends of the shell of the axial section. The useful life is affected by the changing frequency of stress, the magnitude of the stress amplitude and the location.
Belt Speed Calculator – Enter the diameter of the pulley and the RPM of the pulley system into the calculator to determine the belt speed.. Understanding Conveyor Belt Calculations. Understanding a basic conveyor belt calculation will ensure your conveyor design is accurate and is not putting too many demands on your system.
For example, if Pulley 1 is 6" diameter, and spins at 1000 RPM, and you need to find Pulley 2 size to spin it at 500 RPM, enter Pulley 1 = 6, Pulley 1 RPM = 1000, Pulley 2 RPM = 500, and hit Calculate to find Pulley 2 diameter.
, required at the drive pulley to propel or restrain the loaded conveyor at the design velocity of the belt V, in fpm: (1) To determine the effective tension, T e, it is necessary to identify and evaluate each of the individual forces acting on the conveyor belt and contributing to the tension required to drive the belt at the driving pulley. T e
Hello, I would appreciate if someone could "shed some light" on why CEMA suggests in CEMA B105.1, the use of the ASME B105.1-83 fully reversed bending and steady torsion equation when calculating minimum pulley shaft diameters. In summary my conveyor will cycle (accelerate, run const speed, drift to rest) approximately every 2 minutes for 20 years …
These calculations are mainly for existing installations but you could also put it towards your design if you want to calculate what the length needs to be of the belt, as long as you already know the distance between the two pulleys and the size of the pulleys.

The belt tension at steady state can be calculated as: Tb = 1.37*f*L*g* [2*mi+ (2* + mm)*cos (δ)] + (H*g*mm)…….eqn.1.1. Where, Tb is in Newton. f = Coefficient of friction. L = Conveyor length in meters. Conveyor length is approximately half of the total belt length. g = Acceleration due to gravity = 9.81 m/sec 2.
The diameter of the pulley must be designed such that it does not place undue stress on the belt. The length of a belt conveyor in metres is the length from the centre of pulley parallel to belt line. Belt length is dependent on both the pulley diameters and centre distances. Capacity is the product of speed and belt cross sectional area.
