ADVANTAGES -Direct connection to SAE J 620, adaptation to other flywheels on request-Compensation of axial, radial and angular displacements-Variable mounting lengths-Backlash-free and maintenance-free-Increased torque transmission capacity by the use of 2 elements-Suited for highest speeds-Optionally light weights by the use of high-strength aluminiumGENERAL TECHNICAL DESCRIPTIONThe highly flexible TOK coupling has been specially designed for applications requiring extremely low torsional stiffness. Furthermore it is particularly well suited to the compensation of axial and radial displacements of flexibly mounted engines. The wide range of flexible coupling elements and adaptive designs provides standard solutions for a wide variety of different tasks. These can be complemented by specific customised designs on request.
The flexible element is designed to combine high torque transmission capacity and high displacement capacity with high speed capability. Its stiffness can be adapted to requirements by selecting different rubber qualities. The adaptive designs are based on the standard flywheel adapter dimensions according to SAE J 620. The TOK coupling series comprises coupling sizes for a torque range from 1 500 Nm up to 86 000 Nm.
The extremely low torsional stiffness allows for a safe and over critical layout of the coupling. During start and stop operations, the resonance range is passed through quickly, and excellent decoupling between the combustion engine and the driven machine is achieved over the entire operating speed range.
The TOK coupling enables direct connection between the engine and the driven machine and is capable of compensating for misalignments resulting from the flexible mounting without requiring any additional components. Most versions even allow for radial disassembly. Restoring forces remain within the permissible limits despite good displacement capability, with a significant reduction in assembly effort and smooth running of the drive (noise reduction).
