        The main parameters and the correct selection of belt drive

        Release time:2016-03-28
        1 data should be known before the design is:
        Transfer power P, speed n1, N2 (or transmission ratio I),
        Transmission position requirements and working conditions.
        2 design to determine the main parameters:
        Belt type, length Ld, root number Z, wheel diameter dd1, DD2, center distance a and so on.
        3 general steps in design:
        Model of the fixed band, DD2,, Ld, a, dd1, Z
        Main parameters and steps of 4.V belt drive
        1) determine the calculation power Pc
        Pc=KAP
        3) determine the diameter of the belt wheel reference D1, D2
        5) determine the center distance a and the band's reference length Ld
        Primary A0
        Initial calculation with length Ld0
        After selecting the reference length Ld, the actual center distance is calculated a
        0.7 (dd1+dd2) A0 2 (dd1+dd2)
        2) select V band model
        4) check with speed v
        (KA is the coefficient of the work situation)
        V=5 ~ 25m/s
        6) checking small wheel angle alpha 1
        7) determine the number of roots Z
        8) to determine the initial tension F0
        F0 acting on the belt wheel axle load
        Alpha 1 = 120
        5 belt wheel material
        Cast iron, cast steel, steel stamping aluminum or plastics
        9) with wheel structure design
        Determine the structure type, material, structure size, drawing with wheel working drawings.
