Spur gears are one of the most common types of gear in gear manufacturing, and offer the familiar shape that most of us recognize as the prototypical “gear.” They’re one of the most ubiquitous gear types, but they aren’t perfect for every application—so what are the biggest advantages and disadvantages of these gears?
The Pros
These are some of the biggest advantages of using a spur gear:
- Transmission efficiency. Compared to other types of gears, spur gears have a high power transmission efficiency, which makes them ideal for preserving the efficiency of a system.
- Straightforward design. Spur gears aren’t complicated in form; this makes them easier to manufacture than other types of gears, and also makes them compact and easy to install.
- Constant velocity ratio. These gears offer a constant velocity ratio, which is ideal for some applications (but not very useful in others).
- Reliability. Spur gears are fairly durable and reliable, with few opportunities for failure.
The Cons
However, there are also some drawbacks:
- Limited center distance. When using spur gears, you need to ensure the gears mesh, in direct contact with each other. This limits the center distance you can have in your machine.
- Noise. At high speeds, spur gears produce significant noise, which can be a problem for some applications.
- Stress. Spur gears take significant stress, so they aren’t ideal for applications that require heavy loads—or else they’ll experience wear and tear that compromises their durability.
