Gear is an important part in machinery industry, it is also the product we place great attention
Our company has a long history of producing gear and
gear shaft, we can make
straight gear,
helical gear,
spiral gear,
bevel gear,
planetary gear system,
ring gear ,
the
spline 
shaft, the
drive shaft ,
Tooth Shaft, and so on.
Our products are widely used in
mine machinery,
petrol chemical industry,
energy appliance,
wind energy equipment,project machinery and machine equipment
We use different kinds of excellent Carbon structural steel, alloy structural steel, cast steel and cast iron. We believe, the qualified raw material is a key factor of qualified gear.
We offer the following heat treatment for the gears and
gear shafts,
straight gears,
helical gears,
spiral gears,
bevel gears,
planetary gears system,
ring gears , the
spline shafts, the
drive shafts ,
Tooth Shafts, Mine Machine parts, Petrol chemical parts, energy equipment parts, Wind Power Equipment parts , Machine gear.
Superficial Quenching
Superficial Quenching is often applied in medium carbon steel and medium alloy steel, such as 45# steel and 40Cr steel. After surface quenching, the tooth hardness could be 40-55 HRC. Its characters are fatigue point corrosion resistance, wear resistance and the good ability for anti-scoring. Because the tooth center is not hardened, the tooth still get enough toughness to bear the impact load.
Quenching Carburizing
Quenching carburizing is often applized in low carbon steel and low carbon alloy steel, such as 20# steel and 21Cr steel, after quenching carburizing, the tooth hardness can reach 56-62HRC, and the tooth center still stay in high toughness. The bend strength and contact strength of tooth are high, wear resistance still quite nice. So this surface treatment is usually used for the importance gear which dure impact load. However, it will cause the tooth deformation and need to be grinded.
Carburizing
Carburizing is a kind of chemical heat treatment for surface. After carburizing, the tooth hardness can reach 700-900HV. Because this heat treatment make the tooth a high hardness with quite low process temperature, and it only cause little deformation, the carburizing is often applied in inner gear, gears hard to grind and the gears of carburizing steel (has Lead, molybdenum, aluminium), such as 38CrMoAl.
Thermal Refining
Thermal Refining is often applied in medium carbon steel and medium carbon alloy steel, such as 45# steel, 40Cr and 35SiMn. After thermal refining, the suface hardness is 220-280HBS. Because
the hard strength is not so high, the precision machining could be done after this heat treatment.
Normalizing
Normalizing can eliminate the inside stress, do the grain refineness, improve the mechanical properties and cutting performance. The medium carbon normalizing can be used in the gear of not so high mechanical stress, and iron steel normalizing can be used in gear of big diameter.
