Timing Gear – Timing gears, as the name implies, are used for various timing reasons. Also called synchronous gears, they may be either spur or helical gears. They are often found in automotive applications to regulate valve timing in engines.
Worm Equipment – A worm gear consists of a worm and a worm wheel working with each other. The worm resembles a screw and may also be known as a worm screw, while the worm wheel looks similar to a spur equipment or helical equipment with a slight helix position. 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 bound.
Spur Equipment – Spur gears are the most typical type of gear. They are used to transmit movement between two parallel shafts and are known for being highly efficient and making a lot of power. Spur gears are known by several other names including straight gears, straight-cut gears, spur tires, and spur gearing. These all have the same simple definition and can be utilized interchangeably.
Pump Gear – A pump gear is the name pertaining to a equipment used in equipment pumps. They consist of both a driver and driven equipment and can become either spur or helical gears. Never to be confused, the term 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 quantity of fluid in a revolution depends on the geometry of the pump gears (i.e. number of teeth, diametrical pitch, etc.).
Spline – Splines are the ridges or teeth (exterior spline) on a drive shaft that mesh with an equal quantity of like ridges or teeth (internal spline) in a mating piece with the goal of transferring torque from one member to the other. The most common splines are parallel key splines, involute splines (carefully related to involute gears but with shorter the teeth, root to tip), and serrations. Splines can be produced 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 straight. There are several different types of sprockets, including silent chain, roller, and ladder sprockets.
Pinion Gear – A pinion may be the Ground Helical Gear Racks 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, depending on the application form. Pinion gears are found in many different types of gearing systems such as for example ring and pinion or rack and pinion systems.
