Power Correction for Angle of Wrap
Using AS2784 Table A12 define the Power Correction for Angle of Wrap for your
selected belt and pulley system.
Then fill in the blanks for your chosen belt system.
The small pulley diameter is
mm, the large pulley diameter
is
mm, my selected centre distance is
mm, and therefore the Power Correction for Arc of Contact is
ANSWER
Small diameter =125 mm
Large diameter = 400 mm
C = 978.2mm
(D-d)/c=0.28
Power correction for arc contact 0.965
