Timing Gear – Timing gears, because 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 found in automotive applications to regulate valve timing in engines.
Worm Equipment – A worm gear includes a worm and a worm wheel operating together. The worm resembles a screw and is sometimes called a worm screw, as the worm wheel appears comparable to a spur equipment or helical gear with a slight helix angle. This set is sometimes also known as a worm drive. Worm gears will be the most compact type of gear and so are often found in applications where space is limited.
Spur Equipment – Spur gears are the most common kind of gear. They are used to transmit motion between two parallel shafts and are known for being highly efficient and creating a lot of power. Spur gears are known by quite a few other names including directly gears, straight-cut gears, spur tires, and spur gearing. These all have the same fundamental definition and can be utilized interchangeably.
Pump Equipment – A pump gear may be the name pertaining to a gear used in gear pumps. They consist of 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 identifies the gears only. Gear pumps are positive displacement pumps, meaning they pump a continuous amount of liquid in each revolution. The volume of liquid in a revolution depends upon the geometry of the pump gears (i.e. number of the teeth, diametrical pitch, etc.).
Spline – Splines will be the ridges or tooth (exterior spline) on a drive shaft that mesh with an equal number of like ridges or tooth (internal spline) in a mating piece with the purpose of transferring torque from one member to the additional. The most common splines are parallel crucial splines, involute splines (closely related to involute gears but with shorter the teeth, root to suggestion), and serrations. Splines could be produced by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are Ground Helical Gear Racks toothed tires whose the teeth engage the links of chains or belts. Sprockets are distinguished from gears in 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 may be the smaller of two meshed gears in an assembly. Pinions gears could be either spur or helical type gears, and be either the traveling or driven gear, based on the application. Pinion gears are found in many different types of gearing systems such as ring and pinion or rack and pinion systems.
