Heavy Duty Spiral Bevel Gear
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 (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.
