Highly Flexible Couplings ELPEX-B Series
ELPEX-B couplings are highly flexible and free of torsional backlash. Because of their low torsional stiffness and damping capacity, ELPEX-B couplings are especially suitable for coupling machines with a highly non uniform torque pattern. ELPEX-B couplings are also suitable for connecting machines with high shaft misalignment.
Standard ELPEX-B coupling types are designed as shaft-shaft connections. Application-related types can be manufactured on request.
The ELPEX-B coupling is available as a catalog standard in 15 sizes with a rated torque of between 24 Nm and 14500 Nm. The coupling can be fitted with elastic tires made of natural rubber for ambient temperatures of –50 °C to +50 °C
and with elastic tires made of chloroprene rubber for –15 °C to +70 °C. The chloroprene rubber tire is marked FRAS, “Fire-resistant and Antistatic”.
The ELPEX-B coupling is suitable for horizontal and vertical mounting positions or mounting positions at any required angle.
The elastic tire is slit at the circumference and can be changed without having to move the coupled machines. The elastic tire is fitted without backlash and gives the coupling linear torsional stiffness, thus the torsional rigidity remains constant as the load on the coupling increases.
The ELPEX-B coupling is especially suitable for reversing operation or operation with changing directions of load. The coupling parts can be arranged as required on the shaft ends to be connected.
If the elastic tire is irreparably damaged or worn, the metal parts can rotate freely against one another because they are not in contact with one another.
