An A-4 flat belt open drive will transfer 20 kW from a 1600 rpm pulley with 285 mm diameter to a 400 rpm shaft. Shafts are horizontal and 2000 mm apart. A service factor of 1.25 and design factor of 1.1 are required.

Find:

a) necessary belt width

b) proper initial tension

c) catenary dip which is required to obtain the calculated initial tension

Hint: Since there is no information about available belt width options from a specific manufacturer, you can use the Preferred Sizes given in Table A-17.
