Design Features of CFBFNCB
Designed using imperial units such as diametral pitch (DP) and standard pressure angles (e.g. 20°), ensuring compatibility with inch-based bevel gears. Features a conical shape to mesh with mating bevel gears at typically 90° shaft angles, enabling angular torque transfer. Made from steel, stainless steel, or alloy metals for excellent strength, durability, and wear resistance under load. CFBFNCB face width is 0.71". Its overall width is 1.802". Available with straight, spiral, or zerol teeth, allowing customization for smoothness, load capacity, or simplicity of manufacture.
What Benefits Can CFBFNCB Provide?
- Accurate Right-Angle Power Transmission: Efficiently transmit torque between intersecting shafts, typically at 90°, with high precision.
- Durability and Load Capacity: Made from strong metals like steel or stainless steel to withstand heavy loads and resist wear over time.
- Smooth and Customizable Operation: Available in straight, spiral, or zerol tooth forms to suit noise, speed, and torque requirements.
- Imperial System Compatibility: Designed to inch-based standards (e.g., diametral pitch), making them ideal for equipment and systems built to imperial specifications.
What Can CFBFNCB Be Used for?
- Gearboxes and Power Transmission Systems: Used in machinery to transfer torque between intersecting shafts—typically at right angles—within inch-based mechanical systems.
- Automotive and Off-Highway Equipment: Applied in differentials, steering systems, and drive units that rely on precise angular motion and imperial components.
- Industrial Equipment: Found in mixers, conveyors, and cutting machines where robust bevel gearing is needed for heavy-duty operation.
- Tools and Mechanical Devices: Integrated into drills, lathes, and custom mechanical assemblies that require inch-standard right-angle torque transfer.
