Anti-resonance couplings

What are antiresonance couplings?

Flexible shaft couplings are mechanical connecting elements that couple two shafts together and are able to compensate for certain misalignments and misalignments. They are made of elastic materials that dampen vibrations and thus increase the service life of machine components.

What is the function of antiresonance coupling?

The main function of antiresonance couplings is to transmit torque from one shaft to another while compensating for axial, radial and angular misalignments. Their elastic properties allow them to absorb vibrations and shocks, resulting in smoother and more efficient machine operation.

Why are antiresonance couplings maintenance-free?

Antiresonance couplings are generally maintenance-free as they have no moving parts to wear out. The flexible materials used, such as special rubber compounds, are designed to maintain their damping properties over long periods of time without the need for replacement or lubrication.

What advantages do they have over other couplings?

Compared to rigid couplings, antiresonance couplings offer several advantages:

• Vibration damping: They effectively reduce vibrations and thus protect neighbouring components from possible damage.
• Compensation of misalignments: They can compensate for axial, radial and angular misalignments between shafts, making installation easier and reducing alignment precision requirements.
• Maintenance-free: Thanks to their design and the materials used, they generally do not require regular maintenance.

What areas of application are there for antiresonance couplings?

Antiresonance couplings are used in a wide range of applications, especially where precision and reliability are required. Typical areas of application are

• Servo drives: In robotics and automation technology, where precise motion control is essential.
• Machine tools: To ensure precise movements and to dampen vibrations during operation.
• General mechanical engineering: In various machines and systems to ensure torque transmission and vibration damping.

The Servoflex SFR coupling from Miki Pulley has been specially developed for use in high-speed and precision applications with servo and stepper motors. It is characterised by high damping performance, zero backlash and the ability to handle speeds of up to 10,000 rpm. By using HNBR as the elastic element, vibrations are efficiently dampened, making them ideal for demanding applications.

Overall, flexible shaft couplings offer an effective solution for torque transmission in various industrial applications by compensating for misalignments, dampening vibrations and remaining maintenance-free.
