Learn MoreV-belt tensioning For the initial installation of optibelt RED POWER 3 V-belts, the same methods are used as for standard Optibelt V-belts. The tension values are to be calculated on the same basis or to be taken from the table on page 147. Once correctly tensioned optibelt RED POWER 3 V-belts need no re-tensioning. Application areas

Learn Moreapplication of the timing belt drive is as rigid as possible. That will guarantee high work repeatability. Drive calculation guidelines Angular drives Elatech belts can be used in angular drives as a "Twisted" drive. In such an application, it is recommended to keep a span length "lt" > 20 † b (belt width) for 90° twist. Omega drive

Learn MoreThe number of belts required for an application is obtained by dividing the design horsepower by the corrected horsepower rating for one belt. The corrected horsepower rating of one belt is obtained by multiplying the horsepower rating from Tables 9 through 12 by the arc of contact correction factor and by the length correction factor.

Learn More25/04/ · 9. Problem 1 Problem Statement: A centrifugal pump running at 340 rpm is to be driven by a 100 kW motor running at 1440 rpm. The drive is to work for atleast 20 hours a day. The centre distance between motor and pump shaft is 1200 mm. Sugest a suitable v-belt drive. Given Data: Power = 100 kW Driver speed (n) = 1440 rpm Driven speed (N) = 340

Learn MoreStep 12: Find the corrected power rate and number of v-belts required; We found the power rate. of the v-belt in step 6. 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. Divide the design power with the corrected power rate of the v-belt.

Learn MoreThe V-belt was developed in 1917 by John Gates of the Gates Rubber Company. It's called a V-belt because of its V shaped cross-section. V-belts (also known as Vee belt or wedge rope) are an early solution that solved the slippage and alignment problem. V-belt is the rubber belt that drives things such as the alternator, air conditioning
