Timing Equipment – Timing gears, since the name implies, are utilized for various timing purposes. Also called synchronous gears, they could be either spur or helical gears. They are 
often used in automotive applications to control valve timing in engines.
Worm Gear – A worm gear includes a worm and a worm wheel functioning jointly. The worm resembles a screw and is sometimes called a worm screw, as the worm wheel looks comparable to a spur gear or helical equipment with a slight helix angle. This set may also be also known as a worm drive. Worm gears will be the most compact type of gear and are often used in applications where space is limited.
Spur Gear – Spur gears are the most typical type of gear. They are accustomed to Ground Helical Gear Racks transmit movement between two parallel shafts and so are known to be highly efficient and generating a lot of power. Spur gears are known by a number of other names including straight gears, straight-cut gears, spur wheels, and spur gearing. All of these have the same basic definition and can be used interchangeably.
Pump Equipment – A pump gear is the name for a gear used in gear pumps. They contain both a driver and powered gear and can be either spur or helical gears. Not to be confused, the word gear pump identifies the entire pump, while pump gears refers to the gears just. 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 upon the geometry of the pump gears (i.electronic. number of the teeth, diametrical pitch, etc.).
Spline – Splines will be the ridges or tooth (exterior spline) on a drive shaft that mesh with the same number of like ridges or the teeth (internal spline) in a mating piece with the goal of transferring torque in one member to the various other. The most typical splines are parallel crucial splines, involute splines (closely linked to involute gears but with shorter teeth, root to tip), and serrations. Splines could be made by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed wheels whose the teeth engage the links of chains or belts. Sprockets are distinguished from gears for the reason that sprockets are never meshed together directly. There are several various kinds of sprockets, which includes silent chain, roller, and ladder sprockets.
Pinion Equipment – A pinion is the smaller sized 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. Pinion gears are used in many types of gearing systems such as band and pinion or rack and pinion systems.
