Timing Equipment – Timing gears, since the name implies, are used for various timing purposes. Also known as synchronous gears, they may be either spur or helical gears. They are generally used in automotive applications to regulate valve timing in engines.
Worm Gear – A worm gear includes a worm and a worm wheel functioning collectively. The worm resembles a screw and may also be known as a worm screw, as the worm wheel looks comparable to a spur equipment or helical equipment with a slight helix angle. This set may also be also known as a worm drive. Worm gears are the most compact type of gear and are often used in applications where space is bound.
Spur Gear – Spur gears are the most common type of gear. They are used to transmit motion between two parallel shafts and are known to be highly efficient and producing a whole lot of power. Spur gears are known by several other names including straight gears, straight-cut gears, spur wheels, and spur gearing. All of these have the same fundamental definition and can be used interchangeably.
Pump Gear – A pump gear is the name pertaining to a gear used in gear 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 Ground Helical Gear Racks refers to the gears just. Gear pumps are positive displacement pumps, which means they pump a constant amount of liquid in each revolution. The volume of fluid 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 teeth (external spline) on a drive shaft that mesh with an equal quantity of like ridges or tooth (internal spline) in a mating piece with the goal of transferring torque from one member to the additional. The most common splines are parallel important splines, involute splines (closely related to involute gears but with shorter the teeth, root to suggestion), and serrations. Splines could 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 for the reason that sprockets should never be meshed together directly. There are several different types of sprockets, including silent chain, roller, and ladder sprockets.
Pinion Equipment – A pinion is the smaller of two meshed gears in an assembly. Pinions gears can be either spur or helical type gears, and be either the driving or driven gear, depending on the application. Pinion gears are found in many different types of gearing systems such as for example band and pinion or rack and pinion systems.
