Abstract RU 2016296 C1

FIELD: mechanical engineering. SUBSTANCE: spiral gear has a metal insertion hub rigidly connected to a polymeric disk which is transformed into a gear rim. The disk is made from polyamide with ribs of stiffness so that the ratio of the rim cross section area to the sum of the disk cross section and ribs of stiffness areas is within 1:2 - 1:4. The number of ribs is determined from a relation presented in the description of the invention. EFFECT: reduced metal usage, simplified structure, facilitated manufacture and improved manufacture ecology. 1 dwg
