PARAMETRIC DESIGN AND FEM-BASED STRENGTH INVESTIGATION OF CYLINDRICAL GEAR TRANSMISSIONS IN THE SOLIDWORKS ENVIRONMENT

The article describes a methodology for parametric modeling, assembly, kinematic analysis and finite element method-based strength evaluation of a single-stage spur cylindrical gear transmission used in the motion transmission mechanisms of technological machines. The study consecutively used the SolidWorks Part, Toolbox, Assembly, Gear Mate, Motion and Simulation modules. FEM results were compared with theoretical calculations performed according to the Lewis, Hertz, AGMA and GOST 21354-87 approaches. The results showed that under nominal operating conditions, the transmission ratio is 3.167, the linear velocity at the mesh point is 4.56 m/s, the maximum bending stress reaches 312 MPa, and the maximum contact stress reaches 492 MPa. The agreement between FEM and theoretical calculations for bending stress was 92.95-99.36%, while for contact stress it was 95.53% relative to the AGMA calculation. The developed approach has practical significance for rapid design, virtual testing and preparation of design documentation for gearboxes of technological machines.
