Comparison of Bending Stress of a Spur Gear for Different Materials and Modules Using AGMA Standards in FEA

Abstract

Gearing is one of the most critical components in mechanical power transmission systems.. This paper explains about the comparison of the geometry of spur gears for two different modules by modeling and mathematical equations, load distribution at various positions of the contact line and the stress analysis of spur gears using three-dimensional finite element method. The bending stresses were examined using three-dimensional finite element model.. These stresses of different modules obtained from the finite element analysis were compared and the considerable reduction of weight occurred was found and also the values are compared with the theoretical values. Both results agree very well. This indicates that the finite element method model is accurate.

Generalised non-dimensional multi-parametric involute spur gear design model considering manufacturability and geometrical compatibility

“…for the influence of module [7,13], addendum [14][15][16][17][18][19][20][21][22], profile modification [23][24][25][26][27][28][29] tooth thickness [30][31][32][33][34][35][36], dedendum [37][38][39][40][41][42], cutter tip radius [43][44][45][46], pressure angle [47][48][49][50][51][52][53][54], etc, but without considering the simultaneous manipulation of other design parameters as well, typically assigning standard values to the latter. Additionally, many researchers have investigated the influences of each design parameter for different applications such as contact analysis [55][56][57][58][59]…”

“…Gear design itself is a complex process that, in spite of much accumulated knowledge and supporting standards, computational models [1][2][3][4][5][6][7] and software [8][9][10][11][12], still critically depends on the experience of the designer, especially if time constraints prohibit an exhaustive iterative multi-parametric search. In fact, the possible independent design parameters that must be studied even in the case of a 'simple' spur gear configuration comprise i.e.…”

Comparative analysis concerning the state of stress for involute gears using ISO, AGMA standards and Finite Element Method

“…There have been numerous studies on bending stress and stress under load caused by contact. [4], [5], [6], but there are few comparative analyses between the standard and FE methods of computing. In paper [7], a detailed analysis for involute spur gears is presented as an example.…”

A New Artificial Immune Algorithm for Solving Gear Design Problem

“…The hybrid algorithm is used for finding optimal make span, mean flow time, mean tardiness values of different size problems. Prabhakaran and Ramachandran [5,6] compared the bending Stress of a Spur and Helical Gears for different gear materials by FEA. Kumar et al [7] optimized internal spur gear with minimization function of center distance using genetic algorithm.…”
