A V-belt drive design needs to be determined. An electrical motor runs 55HP at 1170 rpm to drive the input sheave of the belt drive. The input sheave transmit the power to the output sheave to run an industrial blower at 680 rpm. The industrial blower to be used 10hr/day. Because of space requirements, the V-belt drive needs to fit an area of 40.5\" times 21.5\" as shown in Figure 1 below. Design a V-belt to satisfy design requirements. (Note that any parameters/values taken from Table(s) and Figure(s) need to be referenced.)

Solution

among flexiable machine elements perhaps v-belt drives have idest industrial application. these belts have trapezoidal cross section and do not have any joints. therefore ,these belts are manufactured only for certain standard lengths. to accommodate these belts the pulleys have v shaped grovss which makes them relatively costiler. multiple groove pulleys are available to accommodate number of belts, when large power transmission is required. v-belt drives are most recommended for shoter center distance. in comoarison to flat belt drives, 1:1 and belt slip is very small. as the belts are endled type, v-belt drives do not suffer from any joint failure and are quit in operation v-belts constitute fabric and cords of cotton, nylon etc and imoregnated with rubber
