The BIBANHC Notched Disc Spring (Slotted Disc Spring) is a precision-engineered elastic component designed for applications that require significant deflection and a specific, often regressive, load characteristic. By incorporating strategically placed notches along the diameter, the BIBANHC disc spring reduces the stiffness compared to standard disc springs, allowing for a more sensitive and controlled spring response.
Manufactured with high-precision CNC machining or laser-cutting technology, the model ensures that stress concentrations at the notches are minimized, providing a reliable and long-lasting solution for complex mechanical assemblies.
Key Advantages of the BIBANHC Notched Spring
- Enhanced Deflection: The notched design allows this spring to travel further than a standard disc spring of the same size, making it ideal for clutch engagement and release mechanisms.
- Customizable Load Curves: The number and depth of the notches on the spring are optimized to create specific load-deflection profiles, including "flat" curves where the force remains constant over a range of movement.
- Reduced Friction: When stacked, the notches can help reduce internal friction and allow for better lubrication flow between the springs.
- Space-Saving Sensitivity: Provides the delicate touch of a coil spring but with the compactness and high-load capacity of a disc spring.
Typical Applications for BIBANHC Springs
The BIBANHC Notched Disc Spring is widely used in precision automotive and industrial systems:
- Automotive Clutches: Providing the "pedal feel" and consistent clamping force in manual and automatic transmissions.
- Braking Systems: Used in heavy-duty disc brakes for spring-applied, hydraulic-release mechanisms.
- Overload Couplings: Acting as a torque-limiter that "pops" or releases at a very specific pressure point.
- Automatic Transmissions: Managing the engagement of gear sets with high precision.
- Damping Systems: Absorbing axial energy in high-speed rotating shafts.
