Planetary Ring Gear Large Internal Ring Gears Steel Gears Suppliers
Internal gears, ring gears, and internal ring gears are
interchangeable terms for the same type of gear. These gears are
composed of a cylindrical shape having teeth inside a circular
ring. The gear teeth of an internal gear typically mesh with the
teeth of a spur gear. Spur gears have a convex-shaped tooth profile
and internal gears have reentrant shaped tooth profile; this
characteristic is opposite of internal gears.
Guangda is a leading manufacturer of gear box parts of the
manufacturing specializing in gear box parts forging and precision
machined and custom solutions in a variety of sizes and types. We
provide different kind of products for the gear box parts including
planet shaft ,sun shaft ,planet gear, internal ring gear, planet
carrier ,head cover ,turque arm etc.

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. |
