The thesis is focuses on the virtual design of a planetary gear speed multiplier of 60 kW under the guidelines of the AGMA2105-D04 and ISO 6336 design standards, as well as the analysis of non-linear contacts using analytical and numerical methods to calculate the load capacity. When the components of the speed multiplier are in operation, many complex phenomena occur due to misalignment, backlash, geometry changes, materials, manufacturing, among others, which directly affect the power transmission capacity. the present research is mainly focused on the modeling and analysis of non-linear contacts in dynamic conditions, but is not limited only to the use of the finite element method; rather, an algorithm based on multibody dynamics is also used. Subsequently, the variability between the results of contact forces is quantified by the Hertz analytical formulation and those obtained by simulations in which working conditions such as torque and type of coupling in dynamic bodies are varied. For dynamic analysis, bodies were considered as rigid-rigid and rigid-flexible couplings, using the MSC software. ADAMS The results show that design standards tend to oversize, and the design with numerical methods are more effective, as long as they are considered with caution. Likewise, the dynamic models show lower load capacity results compared to the static analyses. Therefore, in general, a variation of 9% was found in the numerical contact analysis with respect to the analytical one. However, this difference is within the acceptable range for this type of analysis according to the literature consulted and the field experience of specialist companies.
