FINITE ELEMENT MODELING AND BENDING STRESS ANALYSIS OF NON STANDARD SPUR GEAR

Spur Gear Tooth Stress Analysis And Stress Reduction

Gears are commonly used for transmitting power. They develop high stress concentration at the root and the point of contact. The repeated stressing on the fillets causes the fatigue failure of gear tooth. The main objective of this study is to add different shaped holes to reduce stress concentration. A finite element model of Spur gear with a segment of three teeth is considered for analysis a...

Comparative Finite Element Analysis of Reconstructed New and Worn Tooth of Spur Gear

Spur gear wears either due to rubbing action between the meshed gears or by the occurrence of unwanted elements like dust particles, metal fragments, etc. which reduces its efficiency and service life. It is always a challenging task to determine the remaining life of a component or the strength of a component once wear has occurred on teeth surface. This paper presents an application of revers...

Non Linear Finite Element Analysis of Reinforced and Unreinforeced Pavements

In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...

A Finite Element Stress Analysis of Spur Gears including Fillet Radii and Rim Thickness Effects

Application Of Solid Modeling In Virtual Manufacturing Of Spur Gear

Manufacturing process of gear is fairly complicated due to the presence of various simultaneous motions of the cutter and the job. In this paper, an attempt is made to generate meaningful design data for a spur gear and the corresponding rack form cutter necessary for the manufacturing process. Using these information, solid models for the cutter and blank are developed and finally gear-manufac...
