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

Spur Gear – Spur gears are the most common type of gear. They are used to transmit movement between two parallel shafts and are known for being highly efficient and creating 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. These all have the same basic definition and can be utilized interchangeably.

Pump Gear – A pump gear may be the name pertaining to a gear used in equipment pumps. They contain both a driver and powered equipment and can become either spur or helical gears. Not to be confused, the word gear pump refers to the entire pump, while pump gears identifies the gears only. Gear pumps are positive displacement pumps, which means 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 will be the ridges or teeth (exterior spline) on a drive shaft that mesh with an equal number of like ridges or teeth (internal spline) in a mating piece with the purpose of transferring torque from one member to the various other. The most common splines are parallel key splines, involute splines (closely related to involute gears but with shorter tooth, root to suggestion), and serrations. Splines can be made by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed tires whose tooth 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, which includes silent chain, roller, and ladder sprockets.

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