Cylindrical Gears Overview
What Are Cylindrical Gears
You use cylindrical gears to transmit power between parallel shafts. These gears have straight or angled teeth cut on the surface of a cylinder. The pitch surface forms a perfect cylinder, which allows for smooth and efficient motion. Cylindrical gears stand out because they offer high transmission speed, excellent power transfer, and easy maintenance. You can modify the tooth design to improve how the gears mesh and perform.
Here is a quick look at the main characteristics of cylindrical gears:
| Characteristic | Description |
|---|---|
| Normal module (m) | Measures the size of the gear teeth and affects how gears mesh together. |
| Helix angle at reference diameter (b) | In spur gears, this angle is 0º. In helical gears, it varies and affects smoothness. |
