Variable Teeth Heavy Duty Cast Iron Spur Gear with Customizable Size for Precision Applications

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.

Application Scenarios:

1. Construction Machinery: Bevel gear sets are used in the rear axles of mining trucks, cement vertical mill reducers, etc.;

2. Mining Machinery: Gear sets are used in spring and hydraulic cone crushers, gyratory crushers, and feeders, etc.;

3. Industrial Equipment: Gear sets are used in robots, heavy-duty machine tools, gearboxes, and reducers, etc.;

4. Marine and Offshore Engineering: Bevel gear sets are used in ship propeller propulsion systems, etc.;

5. Chemical and Petroleum Industry: Bevel gear sets are used in the rotary tables of oil drilling platforms;

6. Railways: Bevel gear sets are used in the transmission systems of high-speed trains, bullet trains, and locomotives, etc.
