The DENTEX^®-Coupling is a flexible gear coupling, which  whose typical features are two
congruent hubs with crowned teeth which transmit torque by meshing with the
internal toothing of a housing component. The coupling sleeve with axially parallel
involute gearing is centered at the tooth flanks of the coupling hub.

The coupling design meets the requirement to compensate radial, angular and
axial shaft displacements in order to release the neighbouring shaft bearings
from non-controlled, additional loads.

Even with the maximum permissible displacement edge, contact of the teeth is excluded and there will be no periodic variation of the angular velocity. The high internal cushioning properties of the plastic material used for the coupling sleeve reduce the effect of shock loading.

DENTEX^®-Couplings are suitable both for horizontal and vertical shaft connection, for reversing and intermittent service. The steel/plastic combination also has the advantage that no lubrication by oil or grease is required; the coupling, therefore, does not need any maintenance.

The 6.6-polyamide used for the coupling sleeve excels by its excellent sliding properties and wear resistance especially by the combination of toughness, hardness and rigidity; it is also resistant to most oils and hydraulic fluids.

Maximum service reliability is guaranteed at temperatures in the range from -25 °C up to +80 °C. It is necessary to use a coupling sleeve in heat stabilised polyamide for temperature up to 140 °C.

Advantages:

• Compensation of axial, radial and angular misalignment of shafts through double cardanic action
• Simple and easy assembly
• High electrical insulating property
• High thermal stability
• No maintenance
