RECORD Couplings

record

Features:

The Jaure® grid coupling has a perfect axial, radial and angular flexibility:


  • It corrects the shaft alignment without creating transversal reactions.
  • It absorbs torsion knocks and oscillations.
  • It absorbs axial drives.
  • It compensates angular misalignment up to 1º15’ and radial misalignment from 0,5 to 3 mm depending on the size.

Under weak loads, the hairsprings of the zig-zag spring are hardly distorted. The maximum distance between the hairsprings support points produces an elastic transmission between the driving force and the driven element. When the load increases, the hairsprings of the zig-zag spring bend appreciably. This makes the distance between the support points smaller. Consequently, the coupling is more rigid at that moment. Under unexpected overload, the deformity of the spring reaches its maximum value. The coupling can keep bearing bigger overloads despite having lost the elastic properties.
