PT Journal AU Medvecka-Benova, S TI Analysis of Gear Wheel Body Influence on Gearing Stiffness SO Acta Mechanica Slovaca PY 2017 BP 34 EP 39 VL 21 IS 3 DI 10.21496/ams.2017.024 DE spur gear; tooth deformation; body of wheel gear; mesh stiffness; FEM 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. ER
