Transmission elements

Transmission elements The transmission elements in glass-fibre reinforced polyamide based technopolymer are an efficient alternative to metal transmission elements and can be used in all applications requiring noise reduction or the avoidance for the need of lubrication. The lightness of the technopolymer transmission elements allows their application in fields requiring a general weight reduction as well. Moreover, the technopolymer's high resistance to chemical agents limits corrosion in aggressive environments. The steel gears are often oversized for the effective application they are used...

Coupling The technopolymer transmission elements can be paired with both technopolymer and metal gears. In the case of coupling with metal gears, the higher thermal conductivity of the metal allows a faster dissipation of the heat accumulated during the operation. In the case of metal-technopolymer coupling, the metal pinion and the technopolymer gear are the best option, as the wear of the technopolymer toothed gear is lower. Operating distance In order to get an optimal meshing between two gears, it is necessary to have a positive backlash between the centers of the two shafts: the effective...

Transmission elements Materials ELESA spur gears and racks are made of glass-fibre reinforced polyamide based technopolymer. The main mechanical characteristics of this type of material are: • High resistance to torsion and tensile strength (about three times higher than acetal resin) Good resistance to high temperatures Low friction coefficient, especially if compared to steel. Accordingly, the technopolymer gears can be used even when lubrication is not allowed Low specific weight, a greater lightness of technopolymer gears over metal gears High dimensional stability, high resistance to wear...
