Timing Equipment – Timing gears, as the name implies, are utilized 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 includes a worm and a worm wheel working collectively. The worm resembles a screw and is sometimes called a worm screw, as the worm wheel appears comparable to a spur gear or helical gear with a slight helix position. This set may also be also called a worm drive. Worm gears are the most compact kind of gear and so are often used in applications where 
space is limited.
Spur Equipment – Spur gears are the most common kind of gear. They are accustomed to transmit motion between two parallel shafts and so are known to be highly efficient and creating a whole lot of power. Spur gears are known by a number of other names including straight gears, straight-cut gears, spur tires, and spur gearing. These all have the same basic definition and can be utilized interchangeably.
Pump Gear – A pump gear may be the name designed for a equipment used in gear pumps. They consist of both a driver and powered equipment and can become either spur or helical gears. Not to be confused, the term gear pump refers to the whole pump, while pump gears refers to the gears only. Gear pumps are positive displacement pumps, meaning they pump a constant amount of liquid in each revolution. The quantity of fluid in a revolution depends on the geometry of the pump gears (i.electronic. number of tooth, diametrical pitch, etc.).
Spline – Splines are the ridges or tooth (external 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 typical splines are parallel essential 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 wheels 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 Gear – A pinion is the smaller of two meshed gears within an assembly. Ground Helical Gear Racks Pinions gears could be either spur or helical type gears, and become either the traveling or driven gear, based on the application form. Pinion gears are found in many different types of gearing systems such as for example ring and pinion or rack and pinion systems.
