How to Calculate Length of Path of Approach?
Length of Path of Approach calculator uses Path of Approach = sqrt(Radius of addendum circle of wheel^2-Radius of Pitch Circle of Wheel^2*(cos(Pressure Angle of Gear))^2)-Radius of Pitch Circle of Wheel*sin(Pressure Angle of Gear) to calculate the Path of Approach, The length of path of approach is the portion of the path of contact from the beginning of contact to the pitch point. Path of Approach is denoted by P1 symbol.
How to calculate Length of Path of Approach using this online calculator? To use this online calculator for Length of Path of Approach, enter Radius of addendum circle of wheel (RA), Radius of Pitch Circle of Wheel (Rwheel) & Pressure Angle of Gear (Φgear) and hit the calculate button. Here is how the Length of Path of Approach calculation can be explained with given input values -> 12753.03 = sqrt(0.022^2-0.0124^2*(cos(0.55850536063808))^2)-0.0124*sin(0.55850536063808).
