Numerical analysis on replacement of integrated planet carrier at maximum torque reduction stage in industrial gearbox

Gearbox is used for the transmission purpose. The parameters like load, environmental effect, type of operation is affecting the carrier in planetary gearbox. The carrier employed in high torque involving stage will experience more forces, so those carriers are preferred with cast iron. But in industries, high torque industrial gearboxes are produced in large quantity so it leads to more investment and time consuming. To overcome that, we suggesting the carrier in the high torque gear box fabricated with structural steel. In this present study, numerical analysis on the casted and fabricated carrier was made. Furthermore, pressure and load are the input parameters selected for analysis. Total deformation, stress and fatigue life are assessed with NX – Nastran for every fatigue analysis. The various model modifications are produced and the analysis is performed using NX-Nastran software. The task is carried out using manual calculation and validation with the aid of kiss-software, and is carried out using SOLIDWORKS 2013, NX – NASTRAN software, through the aid of CAD modelling and final element analysis.
