LiNNOTAMDRiVE - Your turn

Drive elements often transmit high torque, and to generate this high power, loads must be transmitted to the elements via the shaft-hub connection. In principle engineering plastics are suitable for these purposes. However, pure plastic designs often reach their limits in such cases. The allowable surface pressure in the keyway is often exceeded or the hubs become distorted under the high load.

Furthermore, plastics are liable to notching, so that in extreme situations there is a danger that the groove in the side under load will give way. Further problems often arise when demands are made on tolerances which are not possible with plastic designs.

This is where the material varieties of LiNNOTAMDRiVE , which have been developed for just these applications, come into use. The combination of LiNNOTAMDRiVE with a metal core combines the advantages and specific properties of both materials in an unusual design material. The knurled metal core is completely covered with a low viscosity melt generated in the monomer casting process. After casting, the polymer cools down and shrinks onto the metal core.

Between the core and the mantle, a powerful bond exists which assures optimal and dependable transmission of power. Due to the surface structure of the metal core, a safeguard against radial and lateral slip is assured.
