Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
