ARPEX

The ARPEX belongs to the family of all-steel lamella couplings. Torque is transmitted through packs of thin, flexible steel laminations bolted to the hubs and a spacer on alternating bolt circles. Elastic deflection of these lamination packs lets the coupling accommodate axial, radial and angular misalignment between the driving and driven shaft without making the torque transmission noticeably compliant in the circumferential direction.

As a torsionally rigid steel lamella coupling, the ARPEX runs maintenance-free, with no wear in the actual transmission element, because it requires no elastomers and no lubrication. It suits applications demanding precise angular fidelity and smooth torque transmission while still having to absorb assembly-related or operational shaft misalignment. The all-metal design is resistant to temperature and ageing and supports operation over long service intervals.

The flexible lamination packs are the central components of the ARPEX and are available as spare parts, so the coupling can be reconditioned when needed instead of being fully replaced.
