ArcuDent - Reich Kupplungen

ArcuDent tooth coupling

The ArcuDent tooth coupling is a double-jointed steel coupling. The teeth of the hubs and covers receive shape corrections to allow the highest misalignment capacity. It is a flexible, but nonetheless torsion-resistant coupling.

The most important characteristics and advantages of ArcuDent tooth couplings:

  • Special Shape of tooth in order to limit noise and vibrations interferences
  • Ring Gear: Gear Teeth optimized by finite elements
  • Tightness with standard o-rings that guarantee the long life of couplings
  • Special gear teeth realized in order to increase the contact surface and to limit the superficial pressure
  • Gear Hub: Bore hub capacity up to 800 mm optimization by finite elements
  • Grade 12.9 screws allow for force-locking torque transmission
  • EX-safety according to ATEX-standards

4 good reasons for ArcuDent tooth couplings!

Precision and high standards
ArcuDent is a 100% steel coupling, manufactured with accuracy by REICH-KUPPLUNGEN. Its components include two internally geared half covers, which are tightened together with a set of treated bolts. The half covers are then assembled onto two geared hubs. The teeth of the hubs and covers receive shape corrections, which are calculated and optimized by REICH-KUPPLUNGEN to obtain maximum contact surface under load, and to allow the highest misalignment capacity.

ArcuDent couplings were designed by the REICH-KUPPLUNGEN engineering department. Their specification was checked by the most elaborate finite elements software.

Reactivity and short delivery time
The ArcuDent Couplings are manufactured in serial production. Spare parts are stocked in the REICH-KUPPLUNGEN warehouse, and in REICH-KUPPLUNGEN distributors warehouses which are present all over the world.

REICH-KUPPLUNGEN has built an ISO 9001 organization inside the company, which reflects REICH-KUPPLUNGEN’s will to answer all requests from the customer. Apart from out research and design departments, a test bench is available for testing the behaviour and reliability of existing couplings and new developments. Out distributors hold a stock of couplings and can assist you in selecting the one you need. 

D2C – Designed to Customer
