The highly flexible iTOK coupling has been specially designed for applications requiring extremely low torsional rigidity. 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 (D2C).
The flexible element is designed to combine high torque transmission capacity and high displacement capacity with high speed capability. Its rigidity 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 iTOK coupling series comprises coupling sizes for a torque range from 600 Nm to 60 000 Nm.
The extremely low torsional rigidity allows for a safe and supercritical layout of the coupling. During start and stop operations, the resonance range is passed through quickly, and excellent de-coupling between the combustion engine and the driven machine is achieved over the entire operating speed range.
The iTOK 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).
The iTOK couplings comply with ATEX explosion protection. They are certified according to Directive 2014/34/EU and may be used in explosive environments (categories 2 + 3). ATEX documentation to supplement the operating instructions is available on request.
