# How do you find the gear ratio between two gears?

## How do you find the gear ratio between two gears?

2. Count the number of teeth on the drive gear. One simple way to find the gear ratio between two interlocking gears is to compare the number of teeth (the little peg-like protrusions at the edge of the wheel) that they both have. Start by determining how many teeth are on the drive gear.

### How is gear ratio related to pinion teeth ratio?

During operation, the pinion makes three complete revolutions for every single revolution of the larger gear. This relationship in which the gear turns at one-third of the pinion speed is a result of the number of teeth on the pinion and the larger gear. This relationship is called the gear teeth – pinion teeth ratio or the gear ratio.

#### How to calculate the gear ratio in hbreducer?

2. Plug your information into the formula S1 × T1 = S2 × T2. In this formula, S1 refers to the rotational speed of the drive gear, T1 refers to the teeth in the drive gear, and S2 and T2 to the speed and teeth of the driven gear. Fill in the variables until you have only one left undefined.

**When to use gear ratio in drilling machine?**

Gear ratios can be used to determine the speed of rotation of a gear set if the input or output speed of the gear set is known. That’s it. If you find this article helpful share with your friends. Have any doubt or questions about “gear ratio” leave a comment I’ll respond. Shaper machine, Drilling machine, Planner machine and more.

**How do you calculate a simple gear ratio?**

The gear ratio formula turns out to be fairly simple. You basically count the number of teeth on the driven wheel and divide that by the number of teeth on the driver wheel, which is the one attached to the motor. It’s a straightforward calculation, even when the gear system consists of several intermediate wheels called idlers.

## What is gear ratio equation?

The gear ratio is necessary for calculating the speed a given gear chain will produce. When you have that information, you have half of the information needed to calculate the speed. The equation is Speed(Gear 1) * Teeth (Gear 1) = Speed (Gear X) * Teeth (Gear X).

### What is the formula for gear rotation?

Making Ratio/Speed Calculations Find the rotational speed of your drive gear. Using the idea of gear ratios, it’s easy to figure out how quickly a driven gear is rotating based on the “input” speed of the drive gear. Plug your information into the formula S1 × T1 = S2 × T2.

#### How do you calculate gear train?

To calculate the gear ratio of a gear train you can multiply the sub gear ratios. In this example we can take the first driven and driver gear ratio and multiply times the second driven and driver ratio.
