Flexible couplings

Type E (catalogue E) from 34 to 49000 Nm

The user is responsible for the provision of safety guards and correct installation of all equipment

EN, EC, ED

Small dimension

Low weight

Low mass moments of inertia

No maintenance

Ensure uninterrupted transmission of power

Possibility of moving critical torsional vibration from the operating area of the mechanical equipment

E coupling are used for all engineering purposes where an uniterrupted transmission of power is required even in presence of unavoidable shaft misalignements

E-AL

Alum rod machined flexible couplings

No sparking execution with builder’s certificate

The flexible coupling blocks (special mix IR-6100-85B) can be used at ambient temperature from -30°C to +120°

 

DESIGN

Coupling:

  • Cast iron GG25 (Standard production)
  • Modular cast iron GGG45 (Special production)

Flexible coupling blocks:

  • Rubber IRG NS80B

OPERATION

The torque is transmitted through flexible coupling blocks. When loaded, the flexible blocks are mainly subjected to compression as the torque increases. The angle of twist initially grows rapidly and then levels off. This non-linear spring characteristic of the E couplings and the favourable damping properties effectively counteract any dangerous increase the working life of the coupling flexibles.

E couplings will compensate to a certain extent for parallel offset misalignment, angular misalignment and axial movement of the shafts, but it should be noted that accurate alignment will increase the working life of the coupling flexibles.

The flexible blocks (Mix-IRG NS80B) can be used at ambient temperatures from -30° C to +85° C.
