Friction springs – find manufacturers and suppliers

Friction springs are mechanical components that absorb and dampen vibrations and shocks through friction. They usually consist of several metal elements that are connected to each other by contact friction.

These springs are designed to convert kinetic energy into heat through friction, thereby controlling and reducing movement.

Below you will find the functionality and types of friction springs, their areas of application and their advantages:

How friction springs work:

Friction springs dampen vibrations by slowing down movement and dissipating energy through friction. They consist of precisely arranged inner and outer rings that interact via conical contact surfaces and with the use of a lubricant, thus reducing the shock or vibration. In the process, 2/3 of the energy supplied is converted into thermal energy, which enables high damping values of 66% as standard.

Types of friction springs:

1. Cylindrical friction springs consist of several interlocking rings or sleeves that are connected by friction.
2. Disk friction springs use disks or plates that work against each other by friction to dissipate energy.
3. Combined friction and metal springs are a combination of metal springs and friction elements to provide both elastic and friction-based damping.

Areas of application for friction springs:

1. Rail vehicles:
Dampen impact forces in railcar couplings and provide vibration damping in running gear.

2. Mechanical engineering:
In heavy machinery and equipment to reduce vibrations and shocks.

3. Bridges and structures:
Used in vibration-sensitive structures to minimize mechanical vibrations, e.g. caused by wind or traffic.

4. Vehicles:
For chassis components or suspensions to dampen vibrations and improve ride comfort.

Advantages of friction springs:

• Effectively reduce vibrations and shock loads due to the friction effect.
• They have a long service life and usually require minimal maintenance.
• Can be used in harsh environments with high loads and extreme conditions.
• Prevent sudden movements or unwanted vibrations, which increases the safety and protection of machines and structures.

Friction springs thus offer a reliable solution for vibration damping in a wide range of applications, especially where high loads occur.

Here are the most important aspects to look out for when buying friction springs:

When buying friction springs, there are some important factors you should consider to make the right choice for your application.

• Consider where the friction springs will be used: Vehicles, engineering, bridges or other vibration-sensitive structures. The area of application will determine the required size and performance of the spring.
• Check the maximum load capacity of the spring. The spring must be able to withstand the forces and shocks that occur in the application.
• Select a spring that is designed for the appropriate load to prevent premature wear or failure.
• The coefficients of friction* of the materials used are critical as they determine the damping efficiency.
• Make sure the spring provides the right amount of friction to effectively absorb the vibrations and shocks.
• Friction springs are often made of robust metals such as steel or special alloys that can withstand high forces and extreme conditions.
• Make sure that the material can withstand environmental conditions, such as corrosion, temperature fluctuations or moisture.
• Select a friction spring with the correct damping level to ensure that it is suitable for the required vibration or shock reduction.
• Too low a degree of damping may not reduce the vibrations sufficiently, while too high a degree of damping may make the system stiffer.
• Find out about the service life of the spring. Some friction springs are maintenance-free, while others need to be cleaned or lubricated regularly.
• Ease of maintenance and susceptibility to wear are important factors for long-term applications.
• Make sure that the spring is suitable for the temperature range in which it is used. High temperatures can affect the frictional properties and material strength.
• The dimensions of the spring must fit your system, especially if space is limited.
• Make sure that the installation is simple and compatible with the existing structure or machine.
• Look for certifications and standards (e.g. ISO) that indicate high quality and reliability.
• Compare the costs of different models and consider the price-performance ratio. A long-lasting, high-quality spring can save costs in the long term through reduced maintenance and fewer failures.

When purchasing friction springs, it is important to consider the application, load capacity, material properties, coefficient of friction and service life. These factors ensure that the springs effectively dampen vibrations, last a long time and function reliably in your specific environment.
