Motor Shaft Load Due to Belt Loading Equations and Calculator

V-belts are friction devices and depend on tension in the belts to prevent slipping. The following equation may be used to calculate the shaft load due to belt pull. Should the load exceed the values shown in Figure 1 (see bottom of webpage) the load should be reduced by reducing the belt tension, which may cause belt slippage, or by increasing the sheave diameter.

Motor Sizing Basics Part 1: Load Torque

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...

Belt Drive - MathWorks

Description. The Belt Drive block represents a pair of pulleys connected with a flexible ideal, flat, or V-shaped belt. The ideal belt does not slip relative to the pulley surfaces. The model accounts for friction between the flexible belt and the pulley periphery. If the friction force is not sufficient to drive the load, the model allows slip.

Conveyor Belt Equations

The required take-up length is calculated as follows, where . S Sp = take-up length (m) L = conveyor length (m) ε = belt elongation, elastic and permanent (%) As a rough guideline, use 1,5 % elongation for textile belts. and 0,2 % for steel cord belts. Note: For long-distance conveyors, dynamic start-up …

Motor Sizing Basics Part 4 - Radial Load and Axial Load

Also make sure the calculated value is under the value in the chart (see above). When pulleys, belts, gears, sprockets, chains, etc. are used as the transmission mechanism, the dynamic radial load is calculated with the following equation. W = T / y. With a belt conveyor, the motor torque provides the driving force that generates work.

Calculated Idler Load (lbs) = CIL = ((WB + (WM x K1)) x SI) + IML Where: WB = Belt weight (lbs/ft) use actual or estimate from Table 5-5 WM = Material weight (lbs/ft) = (Q x 2000) / (60 x Vee) Q = Quantity of material conveyed (tons per hour) Vee = Design belt speed (fpm) SI = Spacing of idlers (ft)

Bearing Load Calculation

For belt drives, an initial tension is applied to give sufficient constant operating tension on the belt and pulley. Taking this tension into account, the radial loads acting on the pulley are expressed by formula (4.9). For chain drives, the same formula can also be used if vibrations and shock loads are taken into consideration. K r=f b・K ...

Conveyor Belt Calculating Chart

10-04-2017· For example: To find the correct number of plies for a conveyor belt 36 in. wide and 300 ft. long, with 20 ft. difference in elevation; handling sand and gravel. Follow the line from the 36-in. width downward until it intersects the 500 length factor line; then follow to the right until the sand and gravel line is intersected; then down to the ply scale, where the ply will be found to be 7.
