Precision gears types

	Planetary Gear Planetary gears, also called epicyclic gear trains, are used in complex applications that require smooth torque transmission, such as drivetrains and automotive transmissions. The spur gear used by planetary gears is called a “sun spur,” which is surrounded by three-plus exterior gears called planet gears
	Internal Gear Planetary gears, also called epicyclic gear trains, are used in complex applications that require smooth torque transmission, such as drivetrains and automotive transmissions. The spur gear used by planetary gears is called a “sun spur,” which is surrounded by three-plus exterior gears called planet gears
	Spur Gear The spur gear, also called a straight-cut gear, is the simplest type of gear available. Straight-sided along the gear wheel’s axis, with straight teeth in line with the axis. Other types of spur gears transmit motion and torque laterally through compatibility with other parallel aligned gears. Such gears are main components in planetary gears.
	Spline Gear Spline gears are either cylindrical or rod-shaped with straight teeth that allow them to transmit motion laterally by fitting inside internal devices or gears.
	Helical Gear Helical gears are fast rotating gears capable of supporting heavy loads efficiently and smoothly. They feature teeth inclined towards the axis of the shaft and positioned like a helix, thus the name. Quieter than many other gears, including spur gears, helical gears are popular with applications that feature both radial loads and thrust loads.
	Double helical gear Double helical gears are a type of helical gear that has two helical faces next to each other with a gap between them. The helix angles on each face are identical but opposing. The use of a twin helical gear set lowers thrust loads and allows for even more tooth overlap and smoother operation.
