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 control valve timing in engines.
Worm Gear – 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 looks comparable 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 used in applications where space is bound.

Spur Equipment – Spur gears are the most common kind of gear. They are accustomed to Ground Helical Gear Racks transmit motion between two parallel shafts and so are known to be highly efficient and making a lot of power. Spur gears are known by quite a few other names including directly gears, straight-cut gears, spur wheels, and spur gearing. These all have the same fundamental definition and can be used interchangeably.

Pump Equipment – A pump gear may be the name for a gear used in equipment pumps. They contain both a driver and driven equipment and can be either spur or helical gears. Never to be confused, the word gear pump refers to the whole 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 volume of liquid in a revolution depends on the geometry of the pump gears (i.e. number of tooth, diametrical pitch, etc.).
Spline – Splines will be the ridges or tooth (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 goal of transferring torque from one member to the additional. The most typical splines are parallel important splines, involute splines (closely linked to involute gears but with shorter the teeth, root to tip), and serrations. Splines could be produced by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed wheels whose tooth engage the links of chains or belts. Sprockets are distinguished from gears in that sprockets should never be meshed together straight. There are several different types 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 driving or driven gear, depending on the application form. Pinion gears are found in many different types of gearing systems such as ring and pinion or rack and pinion systems.
