By an Hutchinson skilled engineer experienced in drive belt systems. Mechanics and machine design equations and calculators design. A belt is a loop of flexible material used to mechanically link two or more rotating shafts.

Belt Speed V d x n 382 V. Input power can be split among several driven pulleys by using a power ratio factor for each pulley. If youre unsure most are rated at 3600.

As with other engineering design problems product designers must first know about their timing belt-pulley application requirements such as the output torque required to do the. L 15 m. The preferred center distance is larger than the largest pulley diameter but less than three times the sum of both pulleys.

Effective pull pounds V. 10Maximum power transmitted. V-belts need larger pulleys for their thicker cross-section than flat belts.

Shaft load F a. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from. Determine the torque requirement.

V-belts trump flat belts with their small center distances and high reduction ratios. The value of transmission power used in designing is the power requirement of the driven machine if obtained or the power of driving unit engine or motor. Standard pulleys are pulleys that have traditional dimensions with one or multiple grooves which mate with classic small-engine and hexagonal-style v-belts.

Vee Belts V Belts Roy Mech L belt pitch length. The diameters of the pulleys are 15 and 30 cm and you want the distance between them to be 15 meters. The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt.

D S 15 cm 015 m. Companion pulleys contain integral spokes which run radially on the pulley. The RPM of the first driven large pulley is transferred to second set small driver pulley and so on.

To calculate the total load inertia of the motor shaft conversion value. Ad Shop A Wide Selection Of Food Processing Products Order Now. The arc of contact correction factor corrects the power rating of the V-belt for pulleys where the arc of the contact differs from 180 degrees.

V W N V P 1 60 09 10 3 2 where. Enter power parameters of the transmission transferred power speed. Typical calculation design of a transmission using a V-belt consists of the following steps.

Multiply the correction factors that you found in step 11 with the power rate to find the corrected power rate of the selected standard v-belt. To calculate multiple pulley sets where the first driven large pulley shaft drives the second driver small pulley and so on enter Initial Small Pulley RPM Number of Sets and Small Diameter Large Diameter and Centers of each Set below. Torque pounds-inches n.

Note that the units are not relevant as long as theyre the same for all variables. Drive force T 1-T 2 Pv. Mechanics machines Two Pulley Connecting Belt Design and Calculations.

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. D L 30 cm 03 m. Convert the value from torque Tq or horse power PS into kW with the formula below.
