Timing Equipment – Timing gears, since the name implies, are used for various timing purposes. Also known as synchronous gears, they can be either spur or helical gears. They are generally used in automotive applications to regulate valve timing in engines.
Worm Gear – A worm gear consists of a worm and a worm wheel functioning jointly. The worm resembles a screw and may also be called a worm screw, while the worm wheel looks similar to a spur gear or helical equipment with hook helix position. This set may also be also called a worm drive. Worm gears will be the most compact type of gear and are often used in applications where space is limited.
Spur Gear – Spur gears are the most typical type of gear. They are used to transmit motion between two parallel shafts and so are known to be highly efficient and producing a whole lot of power. Spur gears are known by several other names including directly gears, straight-cut gears, spur tires, and spur gearing. All of these have the same basic definition and can be Ground Helical Gear Racks utilized interchangeably.
Pump Equipment – A pump gear is the name intended for a equipment used in equipment pumps. They consist of both a driver and powered gear and can end up being either spur or helical gears. Never to be confused, the word gear pump identifies the 
whole pump, while pump gears identifies 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.electronic. number of the teeth, diametrical pitch, etc.).
Spline – Splines are the ridges or the teeth (external spline) on a drive shaft that mesh with an equal amount of like ridges or the teeth (internal spline) in a mating piece with the purpose of transferring torque in one member to the various other. The most common splines are parallel key splines, involute splines (carefully linked to involute gears but with shorter tooth, root to suggestion), and serrations. Splines can be produced by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed tires whose teeth engage the links of chains or belts. Sprockets are distinguished from gears in that sprockets are never meshed together straight. There are several various kinds of sprockets, including silent chain, roller, and ladder sprockets.
Pinion Gear – A pinion may be the smaller sized of two meshed gears within an assembly. Pinions gears could be either spur or helical type gears, and be either the driving or driven gear, based on the application form. Pinion gears are found in many different types of gearing systems such as band and pinion or rack and pinion systems.
