JAUFLEX® Couplings

Jauflex

 

Features:

  • The hubs of the JAUFLEX® couplings are of the jaw type, made of steel.
  • The cavities for the flexible element are precision machined, not cast.
  • The elastomeric elements are barrel-shaped and interconnected by a ring. This forms a single piece, which is easy to install and remove.
  • Three elastomers with different hardness are available.
  • A high hardness element can be selected for large torque capacity. Alternatively, a soft element can be used for smooth torque transmission.
  • The elements eliminate the transmission of torsional vibration both through their elasticity and through their high damping factor.
  • Air circulation is provided on both sides of the element for easy heat removal.

Benefits:

  • It accommodates offset, angular and axial misalignment.
  • It is comparatively small in size and weight.
  • The fact that it is machined and that the elastic element is very light and precision molded, creates a small residual imbalance. Further balancing can be performed if necessary.
  • The long life of the elastomeric element is ensured by the smooth surfaces of the hub jaws.
  • Requires no lubrication.
  • Requires minimal maintenance.
  • Inherently electrically insulated, as there is no metal to metal contact between the two hubs.
Jauflex

The construction of the Jaure® JAUFLEX® coupling allows it to accommodate the inherent offset and angular misalignment between the connected shafts. It handles most axial displacement caused by thermal growth. It can also accommodate small machine movements caused by foundation settling or pipe stresses.

The JAUFLEX® coupling can tolerate many errors in machine alignment. However, it is best to perform a good alignment so that the coupling can accommodate later movements between shafts.

-Coupling designation example S 145 A - VkR
-Technical features and torque capacity see Page 5
-Coupling torques are given for VkR elastic element
-Elastic element in three different hardness (PB82, VkR y Vk 60D)
(1) Distance "L" is the mininum distance, this distance has to be increased if thermal expansion is to be expected in the same amount.
In this way the axial force between hubs and elastic element due to this expansion is avoided.
(2) GD2 = 4J
