Model for stress analysis of spur Gear Blank
2007Co-Authors: Gordana MarunićAbstract:The 3D models are developed for the stress analysis of a spur thin-rimmed Gear Blank elements. Geometrical models are evaluated for the case of middle-web position and chosen facewidth value, by varying the values of two Gear parameters i.e. the rim and web thickness. Through the using finite element method, the stress of rim and web joint is determined for different models of pinion-wheel system. The accomplished stress comparison of maximum obtained stresses and their distribution in radial direction, offers the decision whether or not the model simplification is possible from reliable Gear Blank elements stress determination point of view.

Effects of Gear Teeth Support upon Tooth-Root Stress Longitudinal Distribution
2006Co-Authors: Gordana MarunićAbstract:The paper deals with the three-dimensional FEM stress analysis of spur thin-rimmed Gears with different Blank structures. The tooth-root longitudinal stress distribution has been established of thin-rimmed Gear without and with web, and for the sake of comparison, of a solid Gear. The tooth-root stresses have been separated and analysed for the engagement position at the outer point of single pair tooth contact. In the case of thin-rimmed Gear with web, two Gear Blank structures have been considered: middle and end web position. The correlation between the effects of a tooth support rigidity determined by the chosen Gear Blank structure and the tooth-root stress have been presented. The stress results have been shown as a function of thin rim thickness and related to the stress values of a solid Gear. The obtained conclusions about tooth-root stress behavior offer some useful information for the buildup of Gear.

Effect of Web Thickness on Thin-Rimmed Gear Stress
2006Co-Authors: Gordana MarunićAbstract:The paper deals with the effect of web thickness upon a tooth-root stress field of a spur thin-rimmed Gear. The Gears of the same teeth geometry and various Gear Blank shape expressed by two different web arrangements along the facewidth, have been the subject of investigation. The values of maximum tooth-root principal stress resulting from 3D FEM calculations, have been the basis for the conclusions about the contribution of thin rim and web thickness to the stress of a tooth above complex foundation.

Tooth-Root Stress Analysis of Thin-Rimmed Gear with Different Web Arrangements
2005Co-Authors: Gordana MarunićAbstract:The paper presents the results of three-dimensional tooth-root stress analysis of spur Gear by finite element method. A partial pinion-wheel model has enabled the simulation of load distribution along the tooth facewidth of thin-rimmed Gear with the web positioned in the middle and at the end of tooth face. The emphasis has been given to maximum tooth-root stress comparison with the corresponding ones of thin-rimmed Gear without web and a solid Gear. The results show that the web arrangement of a Gear Blank has significant effect on tooth-root maximum stress including its magnitude and position along the fillet.

the key technology and realization of virtual ring rolling
Journal of Materials Processing Technology, 2007Co-Authors: Zheng Wang, Shaoqun Zeng, Xinhua Yang, C ChengAbstract:Abstract Aiming at the difficulty in realizing three-dimensional dynamic simulation of ring rolling process, this paper firstly analyzed some key technologies and gave out related solution schemes, in which the LS_DYNA code and its mass scaling function is adopted to reduce the compute time, and a user-defined ANSYS Parametric Design Language program is developed to control the complex movements of the guide rolls and axial rolls. And then this paper created the three-dimensional simulation models of a rear axle bevel Gear Blank, an aero-engine turbine casing Blank and a great conical ring of the 600 MW nuke reactor shell, and realized the entry virtual rolling process of these profile rings, respectively. The real-time dynamic process of ring enlarging and fleck generating as well as the stress, strain and displacement contours are given out as the results and then compared to the practical rolling process. Good agreement is obtained and thus demonstrates that this simulation method is feasible and can be used to guide the design and optimization of the ring rolling process.
