RT STEEL-BOLTED RUBBER COUPLINGS Features

product_lines_1126225917

The RT bolted rubber flexible coupling, most often used aft of the gearbox, provides dynamic mobility to a resiliently-mounted engine and minimizes bending stresses in the gearbox output shaft.  Additionally, the RT coupling here has significant mechanical and acoustic attenuation, keeping engine and gear noise away from the low-speed shafting and bearings. Dynamic Magnifier values as low as 3.5 can be provided with high-damping elastomer elements.
  • Two-directional (propeller) thrust capability
