What is the significance of Pulley pitch circle/diameter ?
The tooth profile of synchronous belts is of trapezoidal shape with sides being straight lines which generate an involute, similar to that of a spur gear tooth. As a result, the profile of the pulley teeth is involute. Unlike the spur gear, however, the outside diameter of a timing pulley is smaller than its pitch diameter, thus creating an imaginary pitch diameter (pulley pitch diameter) which is larger than the pulley itself. Pulley pitch circle coincides with the belt pitch line over the meshed teeth part.
How to Calculate Pulley outside Diameter given Distance between Belt Pitch line and Pulley tip circle radius?
Pulley outside Diameter given Distance between Belt Pitch line and Pulley tip circle radius calculator uses Pulley Outside Diameter = Pulley Pitch Diameter-(2*Belt Pitch Line and Pulley Tip Circle Radius Width) to calculate the Pulley Outside Diameter, The Pulley outside Diameter given Distance between Belt Pitch line and Pulley tip circle radius formula is defined as subtraction of the distance between the belt pitch line & pulley tip circle radius from the pulley pitch diameter. Pulley Outside Diameter is denoted by do symbol.
