An open flat belt is to transmit 8 kW. The small pulley has a diameter of 175 mm and rotates at 810 r/min, whilst the large pulley runs at approximately 250 r/min. Both pulleys have a width of 110 mm. The centre distance between the pulleys is 800 mm. Assume a factor of safety of eight (8) and an ultimate tensile stress for the flat belt material of 20 MPa. Assume μ = 0.35. 2.1 Specify a belt; i.e. the width, thickness, length and grade 2.2 Calculate a suitable initial tension. An open flat belt is to transmit 8 kW.
