N-EUPEX DS pin coupling



N-EUPEX DS couplings without fail-safe device allow positive disconnection of input and output side upon failure of the flexible elements due to overload or wear. Then, the metal parts of the DS coupling can freely rotate in opposite directions. 19 sizes offer a wide range of applications. DS couplings are offered in a torque range between 19 and 21,200 Nm. Many types are available ex stock.

 

Function

In the case of the N-EUPEX DS coupling series, the elastomer flexible is subjected to bending and compression loads. In the event of overload or advanced wear, the coupling disconnects positively and the flexibles are irreparably damaged. The metal parts then rotate without touching one another. After new elastomer flexibles are fitted, the N-EUPEX DS coupling is once more operable.

N-EUPEX DS couplings are maintenance-free, even in potentially explosive environments, so long as the possible torque interruption does not lead to an unacceptable disruption of the production process.

Examples of application

N-EUPEX DS couplings can be used universally in the whole field of mechanical engineering. They are particularly used in sensitive machines where input and output side are to be disconnected upon failure of the flexible elements or where the coupling must be maintenance-free.

Typical examples of application are:

  • Pump drives

  • Compressor drives

  • Fan and blower drives
