RT Journal Article SR Electronic A1 Medvecká-Beňová, Silvia T1 Analysis of Gear Wheel Body Influence on Gearing Stiffness JF Acta Mechanica Slovaca YR 2017 VO 21 IS 3 SP 34 OP 39 DO 10.21496/ams.2017.024 UL https://www.actamechanica.sk/artkey/ams-201703-0006.php AB The development of modern machinery and production facilities is characterized by constantly increasing performance parameters at the decreasing weight of the machine. It is also a characteristic of the design of the body shape of larger wheel gears. The lowering the weight of the body of wheel gears affects to the deformation and mesh stiffness of the gearing. This work is dealing with the design of large gears, which is assessed based on tooth deformation and mesh stiffness of gearing. The task of this work is decide the design of a body of big gear wheels made as monolithic unit, relative on tooth deformation in meshing, accordingly on the mesh stiffness of gearing. Tooth deformation is calculated by finite element method.
