Design and Analysis of Epicyclic Gear Trains

Project Title:-

Design and Analysis of Compound Epicyclic Gear Trains

Aim:-

To Design Model and Analyze by Varying different Variables for a particular model for compound epicyclic

gear train(with all its components) taken from a real model so that the gears will not fail for a particular

power input and material.

Approach:-

First all the dimensions of the Gears (i.e. sun, planet and annulus), shafts( input and output power

shaft), keys, Gear arms, keyways etc are calculated.

In Designing we also calculate all the loads on all the Gears

and eventually on the complete Gear Train which included

dynamic, Static and Wear tooth loads manually.

Designing Also included selection of the material for the

Gears.

The Modeling in the project was carried on Solidworks and

analysis on Cosmos Solid works and Ansys.

The manufacturing processes of the different components

were also determined.

The Loads are calculated by varying the modules of the

gears.

Power acting on the compound epicyclic gear trains is also varied and graphs are plotted to see the

load behavior.

The plotted graphs can be used to verify the compound epicyclic gear train model for different

favorable conditions. This was developed as a chart which shows all the favourable conditions for

different set of specific gear trains.

Manufacturing process of components were also determined.


Steps to Draw a Gear:-

First the pitch circle, addendum circle, dedendum circle and root circle are drawn.

Center lines are drawn and a point is located on the pitch circle. The distance of the point gives the

tooth thickness.

The point on the pitch circle is joined to the center of the circle by a line. A vertical line also passes

through the same point. A line of 200 with the

vertical is also drawn; this indicates the

pressure angle.

All the unnecessary lines are trimmed to form

half shape of the tooth profile. By using a

spline curve the tooth profile is formed

Fillets at the radius of the tooth and the tip of

the tooth are given.

The wire frame model of half tooth profile is

mirrored with respect to the vertical axis.

Deleting and trimming all the unnecessary lines, circles and other entities; leaving only the tooth

profile and base circle. Give the command “circular pattern”.

As the result of previous step we get the wire frame

model of the gear.

Give the command “extrude Boss/Base”. The

command prompts to give the width of the gear.

Enter the value. We get the required model of the

gear.


Analysis:-

By taking a particular material for the gear and by varying its module, power input etc, the different

loads (tangential, dynamic, static and wear tooth loads) were determined for all the gears(sun, planet

and annulus) in the epicyclic gear train.

This was again done for various materials and all the different values were determined.

These values were them plotted into graphs and the results were analyzed.

A complete chart was created by which any gear with its preferable conditions could be selected by

analyzing all the variables.

Simultaniously a saperate analysis on Ansys was also carried out

Results:-.

The Complete Design with all the specifications of the gears were determined, all the loads were also

calculated. A complete working Model was developed in Solidworks CAD software with all its

specifications. Analysis of the epicyclic Gear Train was successfully completed with all its results collected

and presented in the form of charts. The stresses were also calculated with the help of Ansys. The

manufacturing process of different components were also determined.

The loads with respect to the module, material and power could be seen from the graphs and a complete

chart was created by which any gear with its preferable conditions could be selected by analyzing all the

variables affecting it.
