Gears are circular machine parts with teeth that mesh with another compatible toothed part to transmit torque and speed.
Gears are usually made from steel, cast iron, plastic, nylon, or fibre.
The American Gear Manufacturers Association (AGMA) and the American National Standards Institute (ANSI) have established the standard US nomenclature used in the description of mechanical gear construction and function.
This includes terms such as addendum, apex to back, back angle, back cone, backlash, base circle, base cylinder, base diameter, bull gear, center distance, central plane, and worm gearing.

This page lists the standard US nomenclature used in the description of mechanical gear construction and function, together with definitions of the terms. It includes terms such as addendum, apex to back, back angle, back cone, backlash, base circle, base cylinder, base diameter, bull gear, center distance, central plane, and worm gearing. The terminology was established by the American Gear Manufacturers Association (AGMA) and was accredited by the American National Standards Institute (ANSI).

Difference Between Gears & Sprockets: Gears and sprockets both use teeth to transfer torque. While at the outset, they both are similar-looking components, there are some marked differences that can help us identify them with ease. 1. Gears are the preferred solution for short-distance transmissions. Using a sprocket and a chainhelps to transmit the power over a considerably longer dis...
Different Types of Gears and Their Uses: There are many types of gears and each one offers some trade-offs. It comes down to what expectations a designer has from a gear train. The factors that may be considered are as follows: 1. Torque/duty cycle needs 2. Rotation speed/gear ratio 3. Service environment 4. Space availability/restrictions 5. Budget Based on these factors, the selection i...
Gear Parameters: Now that we have a general idea of the different types of gears, we are in a better position to get a bit technical and understand the meaning of various terms that one may come across while learning about gears.
Tooth Profile: Tooth profile refers to the shape of a gear tooth. There are many different options we can choose from. We could make them rectangular, triangular, in the shape of a circular arc, or move on to more complex shapes such as a parabola or an involute. Simple shapes such as rectangles and triangles, however, create high vibration, noise, and would be v...
Gear Materials and Surface Treatment: Gears are produced using a variety of material and this selection will also affect the surface treatment method that may be chosen to improve performance. Gears may be produced from different types of metalsas well as non-metals such as steel, cast iron, plastic, nylon, and fibre. Each material has its own salient features: 1. Steel is used for int...

A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel , inserted teeth (called cogs ), which mesh with another (compatible) toothed part to transmit (convert) torque and speed
