Özet
In this study, asymmetric gear mechanisms having the same working conditions, material and dimensions as symmetric gears but with different pressure angles were designed and compared with symmetric gear mechanism. The effect of the change in pressure angle and profile crowning has been studied in two spur gear pairs with different tooth numbers. First of all, symmetrical and asymmetrical gear geometries were created to meet the specified boundary conditions. Unlike other studies, contact stress, specific sliding, flash temperature, contact temperature, transmission error and gear mesh efficiency, which affect gear life and performance, have been investigated simultaneously with the change in load bearing capacity. The asymmetric gear design and profile crowning improved the factors effecting performance. Profile crowning has been shown that significantly reduces transmission error at all pressure angles. Furthermore it has been seen that is efective at low pressure angle in reduction of spesific sliding, flash temperature and contact temperature As a result of the change in the tooth profile by increasing the pressure angle, it was observed that the load bearing capacity, performance, life, efficiency and reliability increased in the asymmetric gear mechanisms with the same gear main dimensions as the symmetrical gears.
