Surface hardening Precision Gears Case Hardening Surface Heat Treatment gears

One way to extend the lifetime of gear is minimizing the distortion during the manufacturing process. One of the most important processes in gear manufacturing is induction surface hardening.

Surface hardening is a heat treating service for reinforcing a metal surface. There are many different types of surface hardening processes. Once reinforced, the finished product is a combo of metals that are much stronger; which allows the object to be used for much longer than originally intended.

Precision gears specification we could provide

Precision gears types 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.

Guangda Core advantage for the precision gears

• Listed company. Strong scientific research ability , Strength for Market experience and customer service .
• Completed industrial supply chain for smelting, casting ,forging, heat treatment to the precision finished processing.
• Better control for the cost ,quality,delivery term as we control every link of the completed chain.
• Certificate PED,DNV, BV, Rina, ISO, GL, ABS, LR etc.

Comparing with companies who only make the material , we directly face the end customers and better understand customer's demand. Compared with comapanies who only do the processing, we can accurately control the quality of materials to meet the technical requirements of customers. In this way we could provide a holistic solution and control the cost of the whole process, meet the delivery time, and resist market risks.
