Frictional connection

Frictional locking occurs when two surfaces are brought into contact with each other with sufficient contact pressure and coefficient of friction. The resulting static friction between the surfaces enables the transmission of torques and axial forces without the need for a positive connection as with feather keys.

Areas of application and advantages of frictional connection

Frictional connection is used in a wide range of mechanical engineering applications, including clutches, brake systems, clamping devices and connecting elements. This method offers the advantage of simple assembly, disassembly and adjustment as well as a high degree of flexibility in the design of mechanical connections.

Materials and surface preparation for frictional connections

The choice of materials for frictional connections depends on the specific requirements of the application, including strength, wear resistance and corrosion resistance. Careful surface preparation by grinding, blasting or coating is essential to achieve optimum frictional properties.

Maintenance and monitoring of friction-locked connections

Regular inspection of the friction surfaces and contact pressure is important to ensure the efficiency and safety of friction-locked connections. Proper lubrication and control of operating conditions also play a role in maximizing the service life and reliability of the connections.
