Timing Equipment – Timing gears, since the name implies, are utilized for various timing reasons. Also known as synchronous gears, they could be either spur or helical gears. They are generally used in automotive applications to control valve timing in engines.
Worm Equipment – A worm gear consists of a worm and a worm wheel operating collectively. The worm resembles a screw and is sometimes known as a worm screw, while the worm wheel looks comparable to a spur equipment or helical equipment with hook helix position. This set may also be also called a worm drive. Worm gears will be the most compact type of gear and are often used in applications where space is limited.
Spur Equipment – Spur gears are the most typical kind of gear. They are used to transmit motion between two parallel shafts and are known for being highly efficient and creating a whole 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 fundamental definition and can be used interchangeably.
Pump Gear – A pump gear is the name for a equipment used in equipment 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 identifies the entire pump, while pump gears refers to the gears only. Gear pumps are positive displacement pumps, which means they pump a constant amount of liquid in each revolution. The quantity of liquid in a revolution depends upon the geometry of the pump gears (i.electronic. number of teeth, diametrical pitch, etc.).
Spline – Splines are the ridges or tooth (exterior spline) on a drive shaft that mesh with the same number of like ridges or tooth (internal spline) in a mating piece with the purpose of transferring torque in one member to the other. The most typical splines are parallel crucial splines, involute splines (closely related to involute gears but with shorter 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 in that sprockets are never meshed together directly. There are several various kinds of sprockets, including silent chain, roller, and ladder sprockets.
Ground Helical Gear Racks pinion Equipment – A pinion is the smaller of two meshed gears within an assembly. Pinions gears could be either spur or helical type gears, and be either the generating or driven gear, 
based on the application. Pinion gears are used in many types of gearing systems such as for example band and pinion or rack and pinion systems.
