Mechanical engineers test, develop, design, analyze, and build various tools and machines. They use power plants and engines to convert energy into mechanical work.
Due to mechanical engineers’ hard work, you’re able to use common household items such as toys, dishwashers, etc. But you might wonder the inner workings of these different devices.
The good news is that the answer is straight ahead. Read this guide and discover what spur gears are and how these mechanical tools work today!
What Are Spur Gears?
They’re the most common type of gear. A spur gear is a disk with a series of uniform teeth along the outer edge.
You’ll find them in everything from washing machines to wind-up toys. They translate the speed of the motor into the rotational force or torque. This is what makes the device work.
The rotational device of the mechanical power is written as a ratio. To have gear reduction, you need two gears to work together.
A spur gear has to be on a shaft that’s parallel to the shaft of the other spur gear for them to mesh. There are different types of gears, including bevel and helical.
The designs of spur gears change according to the thickness and shape of the gear hub. They change without any difference in the face of the gear.
The Different Types of Spear Gears
Depending on gears specifications it’s determined by the material, construction, and design. A large part of it is how they’re fabricated.
The pitch diameter is the outer diameter of a gear. It determines the distance between mating gears.
The diametral pitch is the gear’s pitch circle and is equal to the number of teeth per inch. The pitch circle is the distance from the face of one tooth to the next. The module is the measurement of the tooth size, normally in millimeters.
Spur gear types for mechanical applications include:
- Internal spur gear
- External spur gear
- Pin hub spur gear
- Type a spur gear
- Spline spur gear
- Keyway spur gear
- Spur gear rack and pinion
- Set screw spur gear
- Plastic spur gears with metal core
Gear trains have multiple gears. They can increase or reduce the speed of the drive.
What Spur Gears Do
Spur gears can be found in robotics, automation, automotive, agriculture, food processing, and other industries. If you see rotation, there’s likely a spur gear involved.
They’re used to decrease or increase the speed of a rotation. They can also keep a synchronized rotation or reverse the direction of it.
Mechanical Tools: Better Understanding What Spur Gears Are
After exploring this guide on the mechanical tools, spur gears, you should better understand what they are. If you work with spur gears, take your time deciding which option is best for your next project!
