EWS metal bellows coupling for high-speed applications revised

The specially for high-speed uses designed metal bellows coupling EWS has been revised and now offers a multitude of new advantages.

Thanks to its high balancing quality and the rotationally symmetrical design with a low moment of inertia, the new EWS can now be used at up to 57,000 rpm.

It is still available in 6 sizes, but now for an higher torque range of up to 700 Nm, with a bore diameter between 5 and 60 mm.

A specially designed conical clamping ring hub is used as a non-positive shaft-hub connection. At the specified tightening torques, the conical ring is pulled against the cone hub in a ‘block stop’.

The initial gap size is thus reduced to zero, which prevents the conical ring from tilting or overloading.

The hubs and bellows of the new ENEMAC EWS coupling are joined in a special micro-plasma welding process, which makes the connection absolutely permanent and the transmission torque of each individual bellows layer is safely transferred to the hub.

The drive element offers optimal backlash-free use in the temperature range from 233 K to 473 K.

Smarter Plant Decisions Start with Simulation: ZETA and MEPEQ Bring INOSIM Insight to the Region

Modern production facilities, especially in the chemical, pharmaceutical, and biotech sectors, are becoming multi-product environments. Multiple process steps, interdependent systems, utilities, and logistics must all work together seamlessly. Designing or optimizing such environments without robust analytical tools can lead to costly delays, inefficiencies, or underperforming assets.  This is where INOSIM Insight, part of the ZETA digital toolbox, transforms
