The brand-new transmission elements are now online together with Elesa machine elements. Glass-fibre reinforced polyamide-based technopolymer and grey colour. Transmission elements count two families: cylindrical spur gears (pressure angle 20°) with straight teeth (ZCL) and racks (pressure angle 20°) with straight teeth (ZCR). Spur gears modules are from 0.5 to 3.0 and racks from 0.5 to 4.0. Racks are available in square section, with or without metal core, with mounting bracket or "T" shaped.
Trasfer of speed
Main function of transmission elements is the transfer of a speed and torque in a mechanical system. Over the last few decades, the evolution in engineering plastics and technopolymers has led to the availability of spur gears in plastic material featuring high mechanical strengths in addition to providing all the advantages of plastics: Corrosion and chemical agents resistance; High resistance to torsion and tensile strength; Noise reduction; Low friction coefficient, which allows the use of gears even in sectors where lubrication is not recommended or even prohibited. A further advantage of these elements, but no less important, is the low specific weight, offering a saving over metal gears, making them ideal where a general weight reduction is required.
