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 Distance from Belt pitch line to Pulley tip circle radius?
Distance from Belt pitch line to Pulley tip circle radius calculator uses Belt Pitch Line and Pulley Tip Circle Radius Width = (Pulley Pitch Diameter/2)-(Pulley Outside Diameter/2) to calculate the Belt Pitch Line and Pulley Tip Circle Radius Width, The Distance from Belt pitch line to Pulley tip circle radius formula is defined as the difference between the pulley pitch radius and pulley outside radius. Belt Pitch Line and Pulley Tip Circle Radius Width is denoted by ap symbol.
