## What is pitch of a gear?

The pitch of a gear is defined as the distance between two identical points on two adjacent gear teeth.

## What is normal pitch in helical gear?

The normal pitch of a helical gear is the pitch of the tool used to cut the teeth. It is measured in a plane perpendicular to the direction of the teeth.

## How to Calculate Circular pitch?

Circular pitch calculator uses Circular pitch=(pi*Diameter of the pitch circle)/Number of teeth on the wheel to calculate the Circular pitch, Circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth. Circular pitch and is denoted by Pc symbol.

### FAQ

What is Circular pitch?
Circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth and is represented as Pc=(pi*d)/T or Circular pitch=(pi*Diameter of the pitch circle)/Number of teeth on the wheel. Diameter of the pitch circle is the diameter of the circle on which the hinge centers of the chain lie, when the chain is wrapped round a sprocket and Number of teeth on the wheel is the count of teeths on the wheel.
How to calculate Circular pitch?
Circular pitch is the distance along the pitch circle or pitch line between corresponding profiles of adjacent teeth is calculated using Circular pitch=(pi*Diameter of the pitch circle)/Number of teeth on the wheel. To calculate Circular pitch, you need Diameter of the pitch circle (d) and Number of teeth on the wheel (T). With our tool, you need to enter the respective value for Diameter of the pitch circle and Number of teeth on the wheel and hit the calculate button.
