The Difference Between Different Kinds of Gears and Everything You Need to Know About Them

Numerous companies, no matter what industry they are in, work a lot with gears, and it is helpful for these companies to understand the difference between different kinds of gears and how they work. Gears, as everyone should know, have been in use since ancient times, dating back before Archimedes’ time. On the other hand, Kore Industries have been producing plastic gears since 2008 and is one of the leading producers of this product. Mass production of different kinds of gears is done using advanced processes that are safe and effective. And the end results are always precise and of the highest quality

But what is a gear, exactly?

It is described as a rotating machine part with teeth that meshes with another toothed part to transmit rotational motion or power. Almost all kind of machinery or device has a type of gear in them, from watches to automobiles and big machines. The classification of gears will help know which type is in what device.

Types of Gears and their Uses

Different machines call for different kinds of gears. Based on material, they can be metal or plastic. Plastic types, that Kore Industries are known for, are produced using plastic injection moulding.

Other kinds can be classified depending on their shapes, the position of the shaft and the teeth and more. When based on the shaft position, there are four types of gears, which are parallel shaft gears, intersecting shaft gears, non-parallel shaft gears and non-intersecting shaft gears.

However, here, we will be describing the different types of gears in general.

  1. Spur Gears. Also called straight-cut gears, it is the simplest type of gear. It is a cylinder with teeth projecting radially. The edge of each tooth is straight and is parallel to the axis of rotation. This is the most produced type of gear at Kore Industries since it is widely used and can achieve high accuracy. Household appliances like washing machines and blenders, as well as construction equipment make use of spur gears.
  2. Helical Gears. These are cylindrical gears with winding tooth lines. Like the spur gear, it is also used with parallel shafts. Helical gears have better teeth meshing and are able to transmit higher loads. They are commonly used in high speed, noiseless applications such as in automotive, printing, textile and food industries.
  3. Gear Rack. A straight rod with same shape and sized teeth at equal distances is called a gear rack. It transfers rotational movement into linear movement. One example of its use is in the steering system of cars.
  4. Bevel Gear. Conical in shape with the teeth cut along the cone, the bevel gear is used to transmit power between two shafts intersecting at one point. It is the main mechanism for a hand drill and is also used in many car differentials.
  5. Miter Gear. These are bevel gears with a speed ratio of 1. This means they are used to change the direction of power transmission without changing the speed. They are suitable for use in office machines.
  6. Worm Gear. Composed of a shaft with a screw shape cut, called the worm, and the mating gear, which is the worm wheel, they form the worm gear when they are together on non-intersecting shafts. They are commonly used in heavy equipment and industrial applications.

Being able to tell the types of gears apart will help companies know how to utilize them effectively. Moreover, they will be able to maximize the uses of different types of gears.

The subject of gears is extensive and you can easily get confused with the different types.
