5 Crowned pulleys are used for flat belts. Grooved pulleys or sheaves are used for round or V belts. Toothed wheels or sprockets are used for timing belts.

14 Quarter-twist belt drive
15 Variable-speed belt drives
16 lat and round-belt drives The efficiency of a V-belt drive ranges from about 70 to 96 percent. lat-belt drives produce very little noise and absorb more torsional vibration from the system than either V-belt or gear drives. When an open-belt drive is used, the contact angles are found to be θ θ d D π sin π + sin 1 1 D d C D d C Where D diameter of large pulley d diameter of small pulley C center distance θ angle of contact
17 The Length of the belt L [4C The angle of wrap is the same for both pulleys and is θ π + The belt length for crossed belts is ( D d) D + d sin 1 C ] 1/ + 1/ ( Dθ + 1/ θ L [4C ( D + d) ] + ( D + D d) dθ d )

22 The flat-belt drive
23 Example 17-1 A polyamide A-3 flat belt 150mm wide is used to transmit 11. kw under light shock condition where K s 1.5 and a factor of safety equal to or greater than 1.1 is appropriate. The pulley rotational axes are parallel and in the horizontal plane. The shafts are 440 mm apart. The 150 mm driving pulley rotates at 9.17 r/s in such a way that the loose side is on top. The driven pulley is 450 mm in diameter. See ig The factor of safety is for unquantifiable exigencies. a) Estimate the centrifugal tension c and the torque T b) Estimate the allowable 1, and allowable power H a c) Estimate the factor of safety. Is it satisfactory.

26 The combination ( 1 ) a, and i will transmit the design power of 11.(1.5)(1.1)15.4kW and protect the belt.
