! "!!# $ ! ! % ! $!! Material xirodur B180 is a wear- resistant endurance runner and
dampens vibrations; while iglidur F also has a long service life and is suitable for applications with high temperatures. This is also electrically conductive. Polymer gears are becoming increasingly popular because they require no
lubrication and are therefore maintenance-free, they are quiet and are often lighter than metal, igus explains. The company has supplied wear-resistant gears made using 3D printing, as well as machined gears made from iglidur bar stock, for several years. According to the company, the gears developed so far from the iglidur
high-performance polymers have a significantly longer service life than gears made from standard plastics. Tests have shown that injection- moulded gears made from xirodur B180 have a four-times longer service life than gears made of the standard POM polymer, the company adds. Depending on the configuration and specific application, igus now offers
manufacturing in three different processes: for fast delivery of wear-resistant customised components within a few days, 3D printed gears made from the laser sintering material iglidur I3 is the process of choice. Machining from iglidur bar stock, for example, is suitable for producing gears in medium volume. Injection moulding offers the greatest iglidur material variety and cost-effective batch production of special dimensions.
$ " ! # ! % % %!! "% % " % # %$"%! % Nabtesco offers a broad portfolio of precision gears with hollow and
solid shafts and provides flexible, high-performance, future viable drive solutions for general mechanical engineering and robotics. The high precision (hysteresis loss of 0.5 to max. 1 arcmin) and rigidity of these gears ensure exact motions for pin-point positioning of components, workpieces and tools – even at high acceleration moments and heavy loads or in hygiene-critical environments. Assembly and handling applications, loading and unloading systems, and also pick-and-place applications, can benefit from the high resistance to shock loads (up to 500% of the rated torque), compact design and long life of the gears. In robotics, cycloidal gears have been the norm for decades, and this
technology is now also taking hold in machine and plant engineering. This technology requires especially user-friendly plug-and-play concepts that are easy to integrate and intuitive to use. Solutions such as the modular servo gearboxes of the Neco series, the dynamic hollow shaft gears of the RD-C series, and the robust rotary indexers of the RS series, allow Nabtesco to meet these requirements.
