Internal Involute Cylindrical Helical Gears

Internal involute cylindrical helical gears are commonly used in various industries. These gears are hardened and manufactured using the forged gear method. They have a spur gear toothed portion shape and are made of alloy steel. They belong to the category of non-circular gears.

Customization options are available for these gears, and customized requests can be accommodated.

Product Description

We are a professional manufacturer of helical gears, specializing in internal helical gears, involute helical gears, and high-quality precision helical gears. Our factory in China produces custom double helical gears.

Here are the material grades we offer for helical gears: Alloy Steel, Carbon Steel, Case-hardening and tempering steel, Stainless Steel, Aluminium alloys, Brass and similar copper alloys, Plastics, Special alloys.

The module of helical gears we produce ranges from 1mm to 50mm. Our helical gears meet various accuracy standards, such as DIN 3960 class 8 to 4, ISO 1328 class 8 to 4, AGMA 2000 class 10-15, JIS 1702-1703 class 0 to 2, and more.

We provide different heat treatment options for our helical gears, including quenching and tempering, gear teeth induction quenching, nitriding, and carburization.

Our helical gears are widely used in wind turbines, locomotives, feeding machinery, metallurgy machinery, mining machinery, coal mining machines, cement mills, railway locomotives, large-scale construction machinery, and large-scale precision reducers, among other applications.
