Last Updated: 8th January, 2020

**gear**, you can find the

**gear ratio**relativelysimply.Divide the driven

**gear**teeth by the drive

**gear**teeth.Depending on your assignment, you may write your answer asadecimal, a fraction, or in

**ratio**form (i.e., x:y).

Moreover, how do you calculate first gear ratio?

**First**, divide the number of teeth of thedriven**gear** (n=30) by the number of teeth of the driver**gear**(n=7). This will result in a **ratio** of 4.285or4.3:1.

how do you calculate sprocket ratio? **Calculating** the **SprocketRatio** The **sprocket ratio** is simply the number ofteethon the driving **sprocket** (T_{1}) divided bythenumber of teeth on the driven **sprocket** (T_{2}).Ifthe front **sprocket** on a bicycle has 20 teeth and therear**sprocket** has 80, the **sprocket ratio** is 20/80 =1/4 =1:4 or simply 4.

Also to know, what is the transmission ratio?

The **transmission ratio** is defined asthe**ratio** of the angular velocities or frequencies ofrotationof the components. The **transmission ratio** of geardrivesconnected in series is equal to the product of the**transmissionratios** of these drives.

What are the 4 types of gears?

**There are three major categories of gears in accordancewiththe orientation of their axes**

- Parallel Axes / Spur Gear, Helical Gear, Gear Rack,InternalGear.
- Intersecting Axes / Miter Gear, Straight Bevel Gear,SpiralBevel Gear.
- Nonparallel, Nonintersecting Axes / Screw Gear, Worm, WormGear(Worm Wheel)
