shows flat belt and V-belt. In the flat belt drive, rim of pulley is slightly crowned which helps to keep the belt running centrally on the pulley rim as shown in\u00a0Figure 15.2(a).\u00a0For the V-belt drive, grooves are made on rim of pulley for wedging action. The belt does not touch the bottom of the groove as shown in\u00a0Figure 15.2(b).\u00a0Owing to wedging action, V-belts need little adjustment and transmit more power, without slip, as compared to flat belts. In multiple V-belt system, more than one belt on the pulleys can be used to increase the power transmission capacity.<\/p>\n\n\n\n

15.2.2  Velocity Ratio<\/h4>\n\n\n\n

Velocity ratio is the ratio of speed of the driven pulley to that of the driving pulley.<\/p>\n\n\n\n

Let   N<\/em>1<\/sub> is rotational speed of the driving pulley<\/p>\n\n\n\n

         N<\/em>2<\/sub> is rotational speed of the driven pulley<\/p>\n\n\n\n

         D<\/em>1<\/sub> is diameter of driving pulley<\/p>\n\n\n\n

         D<\/em>2<\/sub> is diameter of driven pulley<\/p>\n\n\n\n

         t<\/em> is thickness of the belt<\/p>\n\n\n\n

\"Equation\"\/<\/figure>\n\n\n\n

i.e., D<\/em>1<\/sub>N<\/em>1<\/sub> = D<\/em>2<\/sub>D<\/em>2<\/sub>, where t<\/em> is very small in comparison to D<\/em>, therefore it can be negelected.<\/p>\n\n\n\n

\"Equation\"\/<\/figure>\n\n\n\n

Slip<\/h4>\n\n\n\n

The effect of slip is a decrease in the speed of belt on driving shaft and then driven shaft.<\/p>\n\n\n\n

Let \u03c9<\/em>1<\/sub> is angular velocity of driving pulley<\/p>\n\n\n\n

     \u03c9<\/em>2<\/sub> is angular velocity of driven pulley<\/p>\n\n\n\n

     S<\/em>1<\/sub> is percentage slip between driving pulley and belt<\/p>\n\n\n\n

     S<\/em>2<\/sub> is percentage slip between driven pulley and belt<\/p>\n\n\n\n

     S<\/em> is total percentage slip<\/p>\n\n\n\n

<\/a>Peripheral speed of the driving pulley \"equation\"<\/p>\n\n\n\n

Speed of belt on driving pulley \"equation\"<\/p>\n\n\n\n

This is also the speed of belt on driven pulley.<\/p>\n\n\n\n

Now, peripheral speed of driven pulley \"equation\"<\/p>\n\n\n\n

If S<\/em> is total slip percentage, peripheral speed of driven pulley \"equation\"<\/p>\n\n\n\n
