Flange coupling

What is a flange coupling?

Flange couplings consist of two flanges that are mounted on the ends of the shafts to be connected. These flanges are connected to each other by screws or bolts, which enables a firm and rigid connection. The main function of the flange coupling is to safely transmit high torques and forces while ensuring precise alignment of the shafts.

Types of flange couplings

There are different types of flange couplings that can be selected depending on specific requirements and applications:

Steel flange couplings: Robust and durable couplings that are suitable for high loads.
Cast flange couplings: Made from cast iron, they offer a cost-effective solution for many industrial applications.
Light metal flange couplings: These are made of aluminum or other light metals and offer a lighter alternative for applications with lower loads.

Advantages of flange couplings in mechanical engineering

The use of flange couplings has numerous advantages:

High load capacity: Flange couplings can transmit very high torques and forces.
Easy installation and maintenance: They are easy to install and maintain, which increases operating efficiency.
Precise alignment: They ensure precise alignment of the connected shafts.
Versatility: Flange couplings can be used in a wide range of industrial applications.

Areas of application for flange couplings

Flange couplings are used in many areas of mechanical engineering:

Drive technology: In motors, gearboxes and pumps for the transmission of torque.
Heavy industry: In rolling mills, presses and other heavy machinery.
Automation technology: In robots and automated production systems.
Power engineering: In turbines and generators for the transmission of large forces.

Selecting the right flange coupling

The selection of the appropriate flange coupling depends on various factors, including the type of shafts to be connected, the required torque transmission, the operating conditions and the specific requirements of the application. Engineers must carefully consider these factors to select the optimum coupling for their needs.

The flange couplings of the “FK” and “FKB” series from TAS Schäfer are rigid solutions for connecting two shaft ends. This can be as a complete flange coupling, consisting of 2 flange halves and 2 shrink discs or optionally as a half flange coupling, consisting of one flange half and one shrink disc. The main function of a rigid flange coupling is the safe and backlash-free connection of two shafts by means of frictional connection. Flange couplings of the “FK” and “FKB” series can be separated directly at the flanges. This simplifies assembly on the respective shaft ends. The shrink discs mounted on the flange halves create a backlash-free connection by pressing the flange hubs onto the shaft ends. Flange couplings are primarily designed to transmit torques. Bending moments as well as axial forces can also be safely transmitted with the flange couplings type “FK” and “FKB”.

The shrink discs mounted on the flange couplings only provide the required forces and do not themselves transmit any forces or torques between shafts and flange halves. They are therefore not in the flow of forces.

Assembly is carried out by sliding the individual flange halves onto the shaft ends and then clamping the shrink discs. In the final step, the individual flange halves are connected by means of bolting.

TAS flange couplings of the “FK” and “FKB” series are used, for example, in marine technology, wind power technology, materials handling technology, mixing and process technology, hydropower technology as well as in crushing plants and elevators.

Types Of Flange Couplings

TAS Schaefer flange couplings prove their special quality and robustness in highly loaded drives through a secure and backlash-free frictional connection. Compared to thermal or form-fit solutions, the easy assembly and disassembly is a decisive factor for maintenance work on drives. TAS Schaefer flange couplings are available in different designs. For smaller installation spaces, we recommend our “FKB” series flange coupling. Here, the shrink discs are positioned on the flange half rotated by 180°. The shrink disc is screwed through the flange blade by means of hexagon socket head screws. This means that the flange coupling can also be used on systems where there is no space on the side next to the shrink discs for suitable tools for clamping the shrink discs. The use of hydraulic shrink discs is also possible. TAS Schaefer flange couplings can not only drive masses, but also brake them. For this purpose we offer our flange couplings optionally with brake discs. Mounting on existing brake discs is also possible, and we will be happy to make any necessary adjustments to our flange couplings. Shrink disc is carried out by means of a hexagon socket head blade screws through the Flange. As a result, the flange, the coupling can also be used on equipment where the side of the Shrink disc is no room for a suitable tool to clamp the Shrink disc is present. The use of hydraulic shrink discs is also possible. TAS Schäfer flange couplings can not only drive the masses, but also braking. For this we offer our flange couplings, either, with brake disc. Mounting to existing discs is also possible, necessary adjustments to our flange couplings, we like to take.
