Timing Equipment – Timing gears, as the name implies, are used for various timing Ground Helical Gear Racks purposes. Also known as synchronous gears, they could be either spur or helical gears. They are generally used in automotive applications to regulate valve timing in engines.
Worm Equipment – A worm gear contains a worm and a worm wheel functioning collectively. The worm resembles a screw and may also be called a worm screw, while the worm wheel appears similar to a spur gear or helical equipment with a slight helix position. This set is sometimes 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 so are known to be highly efficient and creating a lot of power. Spur gears are known by several 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 intended for a gear used in equipment pumps. They contain both a driver and driven equipment and can be either spur or helical gears. Not to be confused, the word gear pump identifies the whole pump, while pump gears refers to the gears only. Gear pumps are positive displacement pumps, meaning they pump a constant amount of fluid in each revolution. The quantity of fluid 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 amount of like ridges or the teeth (internal spline) in a mating piece with the purpose of transferring torque from one member to the additional. The most common splines are parallel essential splines, involute splines (carefully related to involute gears but with shorter tooth, root to suggestion), and serrations. Splines could be made 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, which includes silent chain, roller, and ladder sprockets.

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