FIELD: mechanical engineering. SUBSTANCE: skew gear includes metal hub, toothed rim and polymer disk which are rigidly connected with hub. Polymer disk and toothed rim are made from glass- filled polymer, for example armamide at rated linear expansion coefficient alpha.. Outer surface of hub is provided with separate H-shaped projections with undercut. Transition of polymer disk to hub is made over radius and outer diameter d of hub is found from relationship given in Specification. EFFECT: improved service characteristics at extremal temperature conditions; improved quality of polymer disk casting. 3 dwg
