25/04/  · 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

application 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

Step 12: Find the corrected power rate and number of v-beltsrequired; We found the power rate. of the v-beltin 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.

Measure the distance between the two pencil marks to determine the circumference of the V belt. Measuring Belt Length without an Existing V Belt Wrap 1/4 inch nylon rope around both pulleys. Overlap 4 inches of the nylon rope. Draw a line across the nylon rope with a black permanent marker.

V-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 146. Once correctly tensioned optibelt rED POWEr 3 V-belts need no r e-tensioning. application areas
