Timing Gear – Timing gears, because the name implies, are used for various timing purposes. Also called synchronous gears, they could be either spur or helical gears. They are generally found in automotive applications to regulate valve timing in engines.
Worm Equipment – A worm gear consists of a worm and a worm wheel functioning together. The worm resembles a screw and is sometimes known as a worm screw, as the worm wheel appears similar to a spur equipment or helical gear with hook helix angle. This set may also be also known as a worm drive. Worm gears are the most compact type of gear and are often found in applications where space is bound.

Spur Gear – Spur gears are the most common kind of gear. They are used to transmit movement between two parallel shafts and so are known for being highly efficient and generating a lot of power. Spur gears are known by quite a few other names including directly gears, straight-cut gears, spur tires, and spur gearing. All of these have the same simple definition and can be used interchangeably.

Pump Gear – A pump gear may be the name to get a equipment used in equipment pumps. They contain both a driver and powered gear and can become either spur or helical gears. Never to be confused, the word gear pump identifies the entire pump, while pump gears refers to the gears just. Gear pumps are positive displacement pumps, which means they pump a constant amount of liquid in each revolution. The quantity of fluid in a revolution depends upon the geometry of the pump gears (i.e. number of tooth, diametrical pitch, etc.).
Spline – Splines are the ridges or teeth (Ground Helical Gear Racks external spline) on a drive shaft that mesh with an equal number of like ridges or tooth (internal spline) in a mating piece with the goal of transferring torque from one member to the other. The most typical splines are parallel important splines, involute splines (closely related to involute gears but with shorter the teeth, root to tip), and serrations. Splines could be made by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed wheels whose teeth engage the links of chains or belts. Sprockets are distinguished from gears for the reason that sprockets are never meshed together directly. There are several various kinds of sprockets, which includes silent chain, roller, and ladder sprockets.

Pinion Gear – A pinion may be the smaller of two meshed gears within an assembly. Pinions gears can be either spur or helical type gears, and be either the generating or driven gear, based on the application form. Pinion gears are found in many types of gearing systems such as for example ring and pinion or rack and pinion systems.
