Common Types of Gears You Will Come Across

Gears are used in almost all types of modern machinery, from simple ones such as bikes to highly complex gearboxes found in automobiles. If you are looking for a gear manufacturer to custom-make gears for your purpose, there are certain things that you should know about the types of gears there are out there. You should first know which one is going to fit your purpose. Some shops specialize in certain types of gears such as bevel gears. In Wisconsin, there are a range of gear manufacturers for you to choose from. Here is a brief overview of the many different types of gears:

1. Spur Gears

Gears are generally either cylindrical or cone-shaped. Spur gears are cylindrical, and they have teeth running parallel to the shaft of the gear. They are among the most common types of gears used. This is because they are relatively easy to make, and they are fit for a range of purposes. There are two spinning cylinders, with the large one being termed the gear and the smaller one the pinion. They rotate counter-clockwise and vice versa to achieve increased speed or force. They are used in common household appliances that do not need to generate very high speeds or thrust.

2. Helical Gears

These also have parallel shafts and are cylindrical. They resemble spur gears as well. However, the main difference between the two types is that the helical gear has teeth that are at a slight angle. This allows them to be more powerful, which is why they are used in machines that reach high speeds or operate at high loading. They are often used in cars due to their ability for smoother transitions and less noise during operation.

3. Gear Racks

These can be very long. They are composed of a straight rod or line with teeth cut into them. They have a pinion or smaller gear running along with them. Their length allows them to transfer rotational motion to linear motion. They can also be helical to generate more loading force. They are commonly used in systems that require linear motion from left to right or vice versa. They can be found in steering mechanisms such as steering wheels and household scales that require tilting. 

4. Bevel Gears

These types of gears have cone-shaped pitch surfaces rather than cylindrical pitch surfaces like the previous ones. They have intersecting shafts, which means that they cross at a certain point. They are good for transmitting power between shafts. They are commonly found in car transmissions as well. The hand drill is another common mechanism that uses this gear. There can be many different types of bevel gears, starting from angular or helical bevel gears to miter or hypoid ones.

Knowing the differences between the various types of gears is really important when you are designing a machine. Choosing the wrong gear can mean that your machine will perform inefficiently or stop working from wearing out. The good news is that there are many different types to choose from, as long as you have a trusted manufacturer.
