Attached on the output shaft of planetary gear box and two s type load cells are used to measure force. The transmission shafts and bearings are designed using the standard force equations. The procedure for analysis of simple epicyclic gear train can be summarised. One is driven at a set torque, the other is regulated at a set speed. Power analysis of twodof epicyclic gear transmission and experimental validation. Introduction to gear trainsintroduction to gear trains. This method is extremely procedural, which is appropriate since use of intuition is often quite futile when applied to complex gear trains. Free body diagrams of gear trains american society for. Pdf epicyclic gear train dynamics including mesh efficiency. What is the ratio of the separation forces and the total force on. Pdf the mechanical efficiency of epicyclic gear trains. Static and dynamic analysis of epicyclic gear train iosr journal. The mechanical efficiency of epicyclic gear trains. We present here a simple, methodical procedure for determining the final gear ratio of an epicyclic gear train.
The tool investigated is from atlas copco st series and consists of three main parts. One of the challenges to those students is that even though the principles to draw a fbd are the same for every mechanical system a fbd is a sketch of a mechanical. Design, load analysis and optimization of compound epicyclic. Critical speed and forced response analysis a manual for computer. Pdf design and analysis of an epicyclic gearbox for an electric. We find the concept of torque per mesh to be somewhat confusing in epicyclic gear analysis and prefer to look at the tangential load at each mesh.
