Internal Spur Gear Internal Ring Gear Internal Bevel Gear Manufacturing For Wind Turbine


Gears are used for the transmission of power. Internal Gears are gear teeth generated in the internal diameter of a cylinder while external gears have the gear teeth generated on the outside diameter of the component.


An internal gear can also be called a ring gear. Internal gears are used in planetary gear box applications, but can also be applied in other situations. Internal gears can also be cut in helical gears just as external gears can be cut in helical gears. These types of internal gears can be found in some internal gear drive, simple pairs, internal differential drives and internal planetary drives.

Precision Gears we could provide


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.
