Static Analysis of Selected Design Solutions for Weight-Reduced Gears

The paper presents an analysis of selected design solutions for spur gears with reduced weight, in which the results obtained are compared to a solid gear without modifications. The reduction of the weight of the gears is of particular importance, among others in the automotive and aviation industries, where it reduces energy consumption, and thus CO2 emissions. It is also important to remember to maintain the required strength parameters when reducing the mass of the gear. This article focuses on the analysis of deformation and stress due to a given load on the considered weight-reduced gears. The values of the obtained static analysis results of the reduced-weight gears were also compared to the base gear.
