Large Module High Precision Spiral Bevel Gear Set with Customized Surface Finishing

Spiral Bevel Gear Set – High Precision Right Angle Transmission Solution

The spiral bevel gear set represents the pinnacle of precision engineering in power transmission components. Comprising a spiral bevel gear and a pinion shaft, this assembly is designed to deliver smooth, efficient torque transfer at 90° angles(mostly), making it indispensable for applications demanding high accuracy, low noise, and robust durability.

Technical Excellence

Design & Geometry: The spiral teeth feature a curved profile that meshes gradually, reducing impact loads and minimizing operational noise. This spiral design also enables higher load-carrying capacity compared to straight-bevel alternatives.

Material & Hardness: Fabricated from premium alloy steel, the gears undergo precision heat treatment (e.g., carburizing, quenching) to achieve a surface hardness of HRC 58–63, ensuring exceptional wear resistance and fatigue strength.

Manufacturing Precision: Employing advanced CNC gear cutting grinding and scraping technologies, our gear set meets DIN3965 Class 5–8 standards for tooth profile, pitch, and surface finish, guaranteeing seamless meshing and long-term reliability.

Hunan Ruida Heavy-duty Machinery and Equipment Co., Ltd. is a well-known enterprise located in LonglingIndustrial Park, Heshan District, Yiyang City. lts predecessor was Changsha Ruida Mold Equipment Co., Ltd. Sinceits establishment in October 2003, it has been dedicated to the research, development, and production of largemodule straight bevel gears and spiral bevel gears.

Our product range is extensive, with straight bevel gears covering a modulus range of 12 to 40mm and adiameter range extending from 200mm to 1700mm. For spiral bevel gears, the modulus range spans from 2 to45mm, and the diameter range is even wider, reaching from 50mm to 2300mm. These high-quality products arewidely used in various fields such as military, high-speed ralil, shipbuilding, petroleum, chemicals, cement,metallurgy, mining, and construction machinery.
