Timing Gear – Timing gears, since the name implies, are utilized for various timing purposes. Also called synchronous gears, they may be either spur or helical gears. They are often used in automotive applications to control valve timing in engines.
Worm Gear – A worm gear contains a worm and a worm wheel working together. The worm resembles a screw and is sometimes called a worm screw, as the worm wheel appears comparable to a spur gear or helical equipment with hook helix position. This set is sometimes also called 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 Gear – Spur gears are the most common type 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 quite a few other names including straight gears, straight-cut gears, spur tires, and spur gearing. All of these have the same simple definition and can be used interchangeably.
Pump Equipment – A pump gear is the name for a equipment used in equipment pumps. They contain both a driver and powered equipment and can end up being either spur or helical gears. Never 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 continuous amount of liquid in each revolution. The quantity of fluid in a revolution depends on the geometry of the pump gears (i.e. number of the teeth, diametrical pitch, etc.).
Spline – Splines will be the ridges or tooth (Ground Helical Gear Racks external spline) on a drive shaft that mesh with the same amount of like ridges or the teeth (internal spline) in a mating piece with the purpose of transferring torque in one member to the various other. The most typical splines are parallel important splines, involute splines (carefully related to involute gears but with shorter teeth, root to suggestion), and serrations. Splines can be made 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 in that sprockets should never be meshed together straight. There are several various kinds 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 can be either spur or helical type gears, and become either the driving or driven gear, based on the application. Pinion gears are found in many different types of gearing systems such as band and pinion or rack and pinion systems.
