## How to Calculate Addendum of the pinion?

Addendum of the pinion calculator uses Addendum of the pinion=( Number of teeth on the pinion/2)*((sqrt(1+((Number of teeth on the wheel/ Number of teeth on the pinion)*((Number of teeth on the wheel/ Number of teeth on the pinion)+2)*(sin(Pressure angle))^2)))-1) to calculate the Addendum of the pinion, Addendum of the pinion is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line. Addendum of the pinion and is denoted by Ap symbol.

How to calculate Addendum of the pinion using this online calculator? To use this online calculator for Addendum of the pinion, enter Number of teeth on the wheel (T), Pressure angle (Φ) and Number of teeth on the pinion (t) and hit the calculate button. Here is how the Addendum of the pinion calculation can be explained with given input values -> 2000 = (10/2)*((sqrt(1+((12/10)*((12/10)+2)*(sin(30))^2)))-1).

### FAQ

What is Addendum of the pinion?
Addendum of the pinion is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line and is represented as Ap=(t/2)*((sqrt(1+((T/t)*((T/t)+2)*(sin(Φ))^2)))-1) or Addendum of the pinion=( Number of teeth on the pinion/2)*((sqrt(1+((Number of teeth on the wheel/ Number of teeth on the pinion)*((Number of teeth on the wheel/ Number of teeth on the pinion)+2)*(sin(Pressure angle))^2)))-1). Number of teeth on the wheel is the count of teeths on the wheel, Pressure angle is the angle which the common normal to the base circles and Number of teeth on the pinion is the count of teeth on pinion.
How to calculate Addendum of the pinion?
Addendum of the pinion is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line is calculated using Addendum of the pinion=( Number of teeth on the pinion/2)*((sqrt(1+((Number of teeth on the wheel/ Number of teeth on the pinion)*((Number of teeth on the wheel/ Number of teeth on the pinion)+2)*(sin(Pressure angle))^2)))-1). To calculate Addendum of the pinion, you need Number of teeth on the wheel (T), Pressure angle (Φ) and Number of teeth on the pinion (t). With our tool, you need to enter the respective value for Number of teeth on the wheel, Pressure angle and Number of teeth on the pinion and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
