Helical Gears

A gear is a particular kind of simple machine that controls the strength or direction of a force. A gear train is made up of multiple gears that are combined and connected by their teeth. These gear trains allow energy to move from...

Planetary Gears

Planetary Gear System

A planetary gear is an epicyclic gear that consists of a central gear, referred to as the sun gear and serves as the input gear, which has three or more gears that rotate around it that are referred to as planets. The planet gears engage with a ring gear that encircles the sun...

Plastic Gears

Plastic Gears

A plastic gear is a toothed wheel made up of engineering plastic materials that work with others to alter the relation between the speed of an engine and the speed of the driven parts. The engineering plastic materials used in manufacturing plastic gears can be...

Spur Gears

Spur Gears

A spur gear is a cylindrical toothed gear with teeth that are parallel to the shaft and is used to transfer mechanical motion and control speed, power, and torque between shafts. They are the most popular types of cylindrical gears and...

Worm Gears

Worm Gears

A worm gear is a staggered shaft gear that creates motion between shafts using threads that are cut into a cylindrical bar to provide speed reduction. The combination of a worm wheel and worm are the components of a worm gear...
