Timing Gear – Timing gears, since the name implies, are used for various timing reasons. 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 jointly. The worm resembles a screw and may also be called a worm screw, while the worm wheel appears similar to a spur gear or helical equipment with hook helix angle. This set is sometimes also called a worm drive. Worm gears will be the most compact type of gear and so are often used 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 are known for being highly efficient and producing a whole lot of power. Spur gears are known by several 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 Gear – A pump gear may be the name for a equipment used in gear pumps. They contain both a driver and powered gear and can be either spur or helical gears. Never 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 teeth, diametrical pitch, etc.).
Spline – Splines will be the ridges or teeth (exterior 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 in one member to the other. The most common splines are parallel crucial splines, involute splines (Ground Helical Gear Racks closely linked to involute gears but with shorter tooth, root to suggestion), and serrations. Splines could 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 various kinds of sprockets, including silent chain, roller, and ladder sprockets.
Pinion Gear – A pinion may be the smaller sized of two meshed gears within an assembly. Pinions gears could be either spur or helical type gears, and be either the driving or driven gear, depending on the application form. Pinion gears are used in many different types of gearing systems such as for example band and pinion or rack and pinion systems.
