Designing the wheel-side planetary reducer of theSGA3550
Abstract
In this article,it introduces the designing of the wheel-side planetary reducer.According to the harsh working environment and the large loads,we choose NGW planetary reducer.This kind of structure is simple, efficient transmission, lower cost and easy to manufacture.
According to the given parameters,choose the best gear numbers and the m..Principle is that make sure the size of the structure is as small as possible. Calculated all parts of the structure’s size, and then check it’s strength.Design the structure forms of the bearings and the spline.
After the completion of mechanical design,we have to establish the main parts of the three-dimensional model with PROE software.While establishing the three-dimensional of the gears,we can ignore the unimportant conditions ,so that we can get a easy and simple model.As the sun gear and the planetary gear bears a large force,so, we can focus on them.
Use the pro/mechanism to analyze the structure’s bearing condition,and compare the result with the ANSYS conclusion.
At last ,we have to import the model into the ANSYS and go on to the next phase of finite element analysis. In finite element analysis, we can choose a different mesh, to compare their results.
