Clamping length

What is meant by clamping length?

The clamping length defines the range over which two components, for example a shaft and a hub, are held together by friction and compressive forces. It is decisive for the transmission of torques and the load distribution within the connection. A correctly calculated clamping length ensures a secure and reliable connection under operating conditions.

Calculation and influencing factors of the clamping length

The clamping length is influenced by various factors, including the surface finish of the contact surfaces, the tightening torque of the fastening elements (such as screws or bolts) and the material properties of the connected components. Engineers use calculation methods and standards to determine the optimum clamping length for specific applications.

Materials and designs for friction-locked connections

Depending on the requirements of the application, different materials and designs can be used to achieve a friction-locked connection with the correct clamping length. Typical designs include conical fits, interference fits or shrink disks, each offering specific advantages and limitations.

Areas of application and significance in practice

Clamping length is widely used in many areas of mechanical engineering, including automotive, aerospace, machine tools and power generation. It is crucial for the reliability and safety of systems and contributes to the efficiency and longevity of machines.
