Timing Gear – Timing gears, as the name implies, are utilized for various timing Ground Helical Gear Racks purposes. Also called synchronous gears, they could be either spur or helical gears. They are generally found in automotive applications to control valve timing in engines.
Worm Equipment – A worm gear includes a worm and a worm wheel working collectively. The worm resembles a screw and may also be called a worm screw, as the worm wheel appears similar to a spur equipment or helical equipment with hook helix position. This set is sometimes also called a worm drive. Worm gears will be the most compact type of gear and are often found in applications where space is limited.

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

Pump Gear – A pump gear is the name for a equipment used in gear pumps. They contain both a driver and powered gear and can be either spur or helical gears. Not to be confused, the term gear pump refers to the entire pump, while pump gears identifies the gears only. Gear pumps are positive displacement pumps, meaning they pump a constant amount of fluid in each revolution. The quantity of liquid in a revolution depends upon the geometry of the pump gears (i.e. number of the teeth, diametrical pitch, etc.).
Spline – Splines are the ridges or the teeth (external spline) on a drive shaft that mesh with the same number of like ridges or teeth (internal spline) in a mating piece with the purpose of transferring torque from one member to the additional. The most typical splines are parallel crucial splines, involute splines (carefully linked to involute gears but with shorter the teeth, root to tip), and serrations. Splines can be produced by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed tires whose the 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 Equipment – 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 traveling or driven gear, depending on the application. Pinion gears are used in many types of gearing systems such as for example band and pinion or rack and pinion systems.
