This paper describes a methodology for modifying a tooth for the ability to transmit torque in one direction only. It presents two methods (analytical and numerical) of tooth mass reduction while maintaining functional features of the whole transmission. The results of the above mentioned methodology are presented on the example of a mass-produced transmission.

W artykule przedstawiona została metodyka optymalizacji geometrii łącznika piasty z wieńcem koła zębatego oparta na metodach numerycznych. Celem optymalizacji było uzyskanie niższej masy łącznika przy jednoczesnym zachowaniu cech funkcjonalnych. W artykule porównane zostały wyniki uzyskane za pomocą obliczeń analitycznych, metody elementów skończonych oraz metody opartej na warunkach i pętlach.

The paper contains a description of the geometry of Beveloid gears. It describes the distribution of forces in a Beveloid gear with a straight tooth line and a helical tooth line. The paper presents research on the experimentally determined parameters of transmission operation, including the sound pressure level and the amount of heat emitted during operation. The design and construction of the test stand were presented. The research methodology was described. Operational tests are carried out on household appliances with Beveloid gears: Grinder and Jam mixer. Thanks to an appropriately selected narrowing angle, estimated values of service life extension of the above-mentioned transmissions are given.
