The forces and torques are calculated accordingly.

. Other belts Flexonic Conveyxonic. Typical calculation design of a transmission using a V-belt consists of the following steps. Horsepower HP Pe.

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. Arc of contact correction factor c 1. A belt is a loop of flexible material used to mechanically link two or more rotating shafts.

The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from. N Number of teeth on pulley. Dynamic balancing is strongly recommended in applications running at high speeds.

FIRST APPROACH FOR ELECTRIC ENGINE. All the page number talked about are from Design Data Book. See Table 2 below for typical values.

Belt speed v π D 1 n 1. L Belt Pitch Length. P Pitch of Belt.

Companion pulleys contain integral spokes which run radially on the pulley. Smallest belt wrap angle α. C Center Distance.

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.

Distance between teeth Cb circumference of belt. Effective pull pounds V. Input power can be split among several driven pulleys by using a power ratio factor for each pulley.

Repair Services Also Available. Horsepower HP Tq. Tb Thickness of belt measured from tooth valley to the flat side of the belt.

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. Design process for Classical V-Belts Narrow V-Belts. D Pitch Diameter Small Pulley.

Dpi Inner Diameter of pulley. This approach is only valid for electric engines and Poly V belts. To determine whether dynamic balancing is advisable perform the following calculation.

RPM of small sheave Power HP Pe x V 33000 HP. Ad Shop Motor Control Solutions For Your Pulley and Sheave Needs. 14 Set the mode of loading and operational parameters type of.

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. Standard pulleys are pulleys that have traditional dimensions with one or multiple grooves which mate with classic small-engine and hexagonal-style v-belts.

Pd design power as determined in Section 311 W belt weight per foot of length lb. By an Hutchinson skilled engineer experienced in drive belt systems. V-belts need larger pulleys for their thicker cross-section than flat belts.

Belt speed feet per minute d. Smartphone version on Apple Store and Google Play Store. Belt Speed V d x n 382 V.

Small sheave pitch diameter inches n. V belt speed fpm 12 Driver RPM Driver Pitch Diameter in π. D is Diameter in millimeters F is Face Width in millimeters.

The preferred center distance is larger than the largest pulley diameter but less than three times the sum of both pulleys. Ht Height of the tooth on the belt. V-belts trump flat belts with their small center distances and high reduction ratios.

RPM 15500 DF 12. Convert the value from torque Tq or horse power PS into kW with the formula below. 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.

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. For example if you found 271 you must use 3. D is Diameter in inches F is Face Width in inches.

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 Tq x n 63025 HP. Torque pounds-inches n.

Shaft load F a. D Pitch Diameter Large Pulley. Drive force T 1-T 2 Pv.

Dpo Outer Diameter of pulley. Belts may be used as a source of motion to transmit power efficiently or to track relative movement. Divide the design power with the corrected power rate of the v-belt.

Optimal speed range is 10007000 ftmin 3002130 mmin.
