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. Mechanical Advantage Output ForceInput Force A mechanical advantage of 1 means that the input force is equal to the output force.

V Belts Design Requirements For Power Requirements Angle Between Sheave

For example if you found 271 you must use 3.

. IS0 4183-1989 Belt drives - Classical and narrow V-belts - Grooved pulleys system based on datum width. D S 15 cm 015 m. Belt Speed V d x n 382 V.

Our Application Technology experts offer you free support service regarding the application of our products and also help. This approach is only valid for electric engines and Poly V belts. All the page number talked about are from Design Data Book.

Shaft load F a. L 15 m. Other belts Flexonic Conveyxonic.

To calculate belt length enter size of. The diameters of the pulleys are 15 and 30 cm and you want the distance between them to be 15 meters. Lets say that you own a factory and you need to calculate a v-belt length.

Belt tension load T 2 T 1 T 2 T 1. Accurately design comprehensive V-Belt transmissions with two or three pulleys by relying on this user-friendly and advanced Excel calculator. V belt speed fpm 12 Driver RPM Driver Pitch Diameter in π.

Input the values into the equation. International Organization for Standardization IS0. Small sheave pitch diameter inches n.

Horsepower HP Pe. A mechanical advantage greater than 1 means that we can accomplish the work with lesser force but exerting it for a greater distance. V-BELT DRIVES This technical manual contains all important technical information and methods for the design and calculation of drives with Optibelt V-belts and V-grooved pulleys for industrial applications.

Drive force T 1-T 2 Pv. The forces and torques are calculated accordingly. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from.

Smartphone version on Apple Store and Google Play Store. Drive torque P2πn 1 Nm. FIRST APPROACH FOR ELECTRIC ENGINE.

1993 V-belts - Endless. The formula for mechanical advantage is. Belt drive power transmission.

Belt speed feet per minute d. Vee Belts V Belts Roy Mech L belt pitch length. Design Pulley Speed Ratio.

Optimal speed range is 10007000 ftmin 3002130 mmin. The RPM of the first driven large pulley is transferred to second set small driver pulley and so on. Typical calculation design of a transmission using a V-belt consists of the following steps.

V W N V P 1 60 09 10 3 2 where. Effective friction coefficient μ μsinβ2- Ratio of belt forces T 1 T 2 expμα- Belt tension load T 1 T 1-T 21-T 2 T 1 N. Pd design power as determined in Section 311 W belt weight per foot of length lb.

V-belts need larger pulleys for their thicker cross-section than flat belts. Arc of contact correction factor c 1. Factors caused by the motor and the application.

Effective pull pounds V. RPM of small sheave Power HP Tq x n 63025 HP. 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.

Horsepower HP Tq. Design process for Classical V-Belts Narrow V-Belts. To calculate the total load inertia of the motor shaft conversion value.

See Table 2 below for typical values. Divide the design power with the corrected power rate of the v-belt. 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-Belt Pulley Design Calculation. Enter power parameters of the transmission transferred power speed. Industrial V-belts classical V-belts have been covered in IS 2494 Part 1.

D L 30 cm 03 m. The number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt. RPM of small sheave Power HP Pe x V 33000 HP.

14 Set the mode of loading and operational parameters type of. If youre unsure most are rated at 3600. 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.

To meet all the expectations of the market Hutchinson has expanded its product portfolio with a range of Hutchinson V-belts timing belts and pulleys. The Design Power is calculated based on these considerations thus producing more accurate results to ensure that the drive will function more efficiently. V-belts trump flat belts with their small center distances and high reduction ratios.

Note that the units are not relevant as long as theyre the same for all variables. Hutchinson develops and manufactures complete power transmission system incorporating ribbed belts for HVAC Conveying industrial motors agriculture and energy supply markets. In a belt drive system a ratio is used to determine the speed relation between two v-belt pulleys.

By an Hutchinson skilled engineer experienced in drive belt systems. Belt speed feet per minute Torque Tq Pe x d 2. Input power can be split among several driven pulleys by using a power ratio factor for each pulley.

Smallest belt wrap angle α. Convert the value from torque Tq or horse power PS into kW with the formula below. Belt speed v π D 1 n 1.

The preferred center distance is larger than the largest pulley diameter but less than three times the sum of both pulleys. Torque pounds-inches n.
