Gear Rack Ratio Calculator

Formula

The formula to calculate the Gear Rack Ratio (R) is:

\[ \text{R} = \frac{T}{2 \pi r} \]

Where:

Gear Rack Ratio (R): A measure of the relationship between the number of teeth on a pinion gear and the linear distance traveled by the gear rack. This ratio is crucial in determining the mechanical advantage and efficiency of gear systems, especially in applications involving linear motion such as steering mechanisms, CNC machines, and other industrial machinery. The gear rack ratio helps in translating rotational motion into linear motion, allowing for precise control and movement.

Let's say the number of teeth on the pinion gear (T) is 30 and the radius of the pinion gear (r) is 2 units. Using the formula:

\[ \text{R} = \frac{30}{2 \pi \times 2} = \frac{30}{12.5664} \approx 2.3873 \]

So, the gear rack ratio (R) is approximately 2.3873.
