There are a variety of different varieties of gears available in the market, manufactured according to material, shafts, sizes and so on, all designed depending on its purpose. There are different criteria used to classify each type of gear, a popular method is usually categorizing them according to the arrangement of shaft or axle. There are for 3 kinds of shaft arrangement, namely parallel shafts, intersecting shafts and non-intersecting or non-parallel axis.

Before launching to further discussion though, let me first define a 'gear'. In layman's expression, a gear is a cylindrically designed toothed wheel that serves as a mechanism to transmit reciprocating or rotational motion from one part of a machine to another. Furthermore when there are two or more gears working with each other the connection between these gears allows power flow from one gear shaft or axle to another.Visit Cardan Shaft India and Universal Joint Manufacturer in India to know more in details about drive shafts which are used in the vehicle.

First, parallel shaft gears are the type of gears that interlock in the same surface level. Illustrations are spur or straight-cut (simplest type of gear), helical (simple helical gear and herringbone or double helical gear). They function as a mechanism to transfer strength of rotational motion between the parallel shafts. The advantages are these gears supply maximum horsepower designed for long-term efficiency. Also, it can carry a high load and does not make much noise when it functions. On the other hand, production of these types of gear is expensive and generates axial thrust. These gears are usually useful for machines with manual transmissions like clock, car steering and more.Get more info about Gears here .

Second, intersecting shaft gears are created to allow smooth exchange of strength and motion between axes that are angled to end up being perpendicular with each other. The following are types of gears that fall into this class: bevel (miter, direct bevel, spiral bevel, and zero bevel or zero), coniflex, angular and crown gear. There purpose is to power machines that require speed and strength since it can handle high load capacity. Compared to parallel shaft, intersecting gears are more inexpensive. These types of gears are used to power hand drills typically, locomotives, marine applications and many more.

Lastly, non-intersecting or non-parallel shaft gears are used on applications that require high-ratio speed reduction that can provide power transmission within a limited area while using gears with non-intersecting axes. Although it is the most inexpensive type of gear, because its production cost can be the lowest, it has a limited load capacity. This setback can be very easily solved by reducing the ratios to increase efficiency. Examples of nonintersecting shaft gears are crossed-helical, worm and hypoid. These are commonly seen on passenger lifts, electric mixer, sprinkler, rear axles of busses and other heavy vehicles among others.

This is only one many systems that categorizes the use of gears. Some categorizes gears relating pitch diameter, materials used to manufacture the gear, manufacturing precision, number of housing and steps design among others. The purpose of these systems is to provide the consumer the information they need to help them purchase the most ideal gear according to their needs. Also, these give them a schedule for criteria.
