TOK coupling and TOK coupling system

Engine manufacturers rely on the TOK coupling system from Reich-Kupplungen

The highly flexible TOK couplings from Reich-Kupplungen are specifically designed to meet the high requirements of engine manufacturers

and test bench operators. They increase the service life and availability of all drive components, thus enhancing productivity. Manufacturers

and operators have ever-growing expectations regarding the efficiency of engine test benches which should excel by high reliability and short

standstill times, and all that at a low total cost of ownership.

Our customers are supplied with couplings and coupling shafts which are tailor-made to the specific engines. Designed for speeds of up to

10,000 rpm, they are particularly well suited for test benches for combustion engine testing. The couplings are mounted between the engine

and the dynamometer and offer a high torsional flexibility and a torque transmission capacity from 100 up to 70,000 Nm. This is why they are

applicable for a wide spectrum of engines. Endurance test benches, research and development test benches, and end-of-line test benches

provide safe and reliable operation with the use of the TOK coupling system.

Reich furthermore provides highly flexible TOK couplings for flexibly mounted engines used in drive trains in the most varied of industries. The

coupling series comprises coupling sizes for a torque range from approx. 1600 Nm to 140,000 Nm. The TOK 910.1, for example, was

specifically developed for large gas engines up to a power rating of 4,500 kW. This coupling for power generation plants is mounted between

the engine and a generator.

Highly flexible couplings from Reich-Kupplungen not only offer an extraordinarily long service life but also shift critical resonance frequencies

of the drive train to below the operating speed range. The design of the coupling is accomplished by employing torsional vibration calculations

which we perform upon the customer's request. For this purpose, various rubber hardnesses are available so that the variation options of our

in-house manufactured elastomers bring about an optimisation of the drive train. Alternating torques of the engine which are generated by

the combustion processes are dampened. This way, all drive components are protected against critical shocks and loads, thus increasing the

service life and availability of the entire installation.
