Ground Helical Gear Racks

Timing Equipment – Timing gears, since the name implies, are used for various timing purposes. Also called synchronous gears, they can be either spur or helical gears. They are often used in automotive applications to regulate valve timing in engines.
Worm Gear – A worm gear includes a worm and a worm wheel working jointly. The worm resembles a screw and is sometimes called a worm screw, while the worm wheel looks comparable to a spur gear or helical equipment with a slight helix angle. This set is sometimes also known as a worm drive. Worm gears are the most compact type of gear and are often found in applications where space is limited.

Spur Gear – Spur gears are the most common kind of gear. They are used to transmit movement between two parallel shafts and are known to be highly efficient and generating a lot of power. Spur gears are known by quite a few other names including directly gears, straight-cut gears, spur wheels, and spur gearing. These all have the same basic definition and can be used interchangeably.

Pump Gear – A pump gear may be the name designed for a gear used in gear pumps. They contain both a driver and powered gear and can end up being either spur or helical gears. Never to be confused, the word 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 continuous amount of fluid in each revolution. The volume of liquid 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 the teeth (exterior spline) on a drive shaft that mesh with an equal quantity of like ridges or the teeth (internal spline) in a mating piece with the purpose of transferring torque in one member to the other. The most typical splines are parallel key splines, involute splines (closely related to involute gears but with shorter the teeth, root to suggestion), and serrations. Splines can be produced by shaping, hobbing or broaching.
Sprocket – Sprockets, or sprocket wheels, are toothed tires whose teeth engage the links of chains or belts. Ground Helical Gear Racks 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 within an assembly. Pinions gears can be either spur or helical type gears, and become either the generating or driven gear, depending on the application form. Pinion gears are found in many types of gearing systems such as for example ring and pinion or rack and pinion systems.
