Shaft example 2012 Shaft Design - conveyor drive pulley A Problem description A shaft has to be designed to suit a drive pulley of a conveyor belt system. The overall dimensions are shown on the diagram below. From experience the customer requires that the inclination of the shaft at the keyways be no more than 1/1200 (tangent or radians).

pacity or the drive unit capacity, some modification will be necessary. •Shorten the conveyor. In some cases, the layout could be changed so that the conveyor becomes shorter. •Divide the conveyor into two separate conveyors with individual drive units. Calculation example The following example involves an accumulating con-veyor with the ...

Example: Model TA, (a slider bed conveyor) 11' long requires 1/2 Hp motor at 65 Feet per minute for a total load of 320 pounds. You desire your conveyor to operate at 90 Feet Per Minute. Calculate as follows: (1/2 X 90) / 65 = .69 You should select the next highest horsepower or 3/4 Hp.

Jun 19, 2019· A simple conveyor system may look like below: The basics of the Calculations of Conveyor Belt Design Parameters. Belt tension: The belt of the conveyor always experience a tensile load due to the rotation of the electric drive, weight of the conveyed materials, and due to the idlers. The belt tension at steady state can be calculated as:

Total Shaft H.P. Calculation. TSHP = FHP + MHP* *Corrected if below 5 HP. Note: The actual motor horsepower required to drive the loaded conveyor system is dependent on the method used to reduce the speed the motor to the required speed of the conveyor. Drive losses must be taken into consideration when selecting the motor and drive equipment.

• Drive pulley shaft For designing a conveyor belt, some basic information e.g. the material to be conveyed, its lump size, tonnage per hour, distance over which it is to be carried, incline if any, temperature and other environmental conditions is needed. 4. DESIGN CALCULATIONS OF CONVEYOR INPUT DATA Bulk density (ρ) – 1.7 T/m 3

Nov 20, 2013· The calculation is actually quite simple. If the speed reduction of the chain or belt drive is N:1, then the gearmotor output speed should be N times the speed calculated for the conveyor roller and the torque output should be 1/N times the torque calculated for the conveyor roller.

1. Calculate the drive torque. T AN. ACCORDING TO TORQUE 2. Base the coupling rated torque T KN on the drive torque T AN multiplied by the application factor. (see page 17 for shock or load factors S A). T KN ≥ T AN · S A Example: Coupling between an electric motor (P=1000kW and n=980 rpm) and a gearbox driving a screw conveyor (S A = 1.6).

The calculation of chain conveyor systems is basical-ly identical formost cases . Starting from the chain's exit point at the drive gear, any frictionand resistance forces during one revolution of the chain are summed up. Since the layout of a conveyor systems is often quite complex including flat sections, curves, slopes, buffers, etc., and ...

The modulus of elasticity is calculated by dividing the stress by the strain, where . M = modulus of elasticity (ISO 9856) F = force (N) ε elast = elastic elongation at the end of the specified number of cycles (N/mm). In other words: The higher the modulus the lower the elastic elongation per unit stress.

conveyor design is based on Calculations while a theory is based on experiments, which are an exhaustible source of knowledge. A theory and calculations are inseparably bound. Without a verified theory taking all the factors into account one cannot make accurate calculations and so one cannot optimally design a belt conveyor.
