“…In order to model the meshing of helical gears, two identical standard gears with specified geometry (see Table 1) was considered in this research. For the sake of simplicity, both thePinion and the gear in the drive have the same geometry in the numerical example [27]. A CAD package Solid Works is used to develop the geometric models of the helical gear drive.…”

“…Gear design and analysis is an area in which the finite element method can provide useful information on stresses, deflection and tooth loads that are needed to design strong and quiet gears [14]. In this study, the 3-D gear modeling and 3-D finite element modeling of gear teeth are also examined.…”

This paper studies the equations of rack cutters for generating involute gears with asymmetric teeth. The asymmetry means that different pressure angles are applied for the driving and coast sides. By applying the equations of the designed profile of the rack cutter, the principle of coordinate transformation, the theory of differential geometry, and the theory of gearing, the mathematical models of involute helical gear are given. Undercutting analysis is also investigated by considering the relative velocity and equation of meshing. Furthermore, a computer simulation program is developed to generate the tooth profile of asymmetric involute gears and to illustrate the effect of tool geometry on the generated surfaces. A CAD/FEM procedure for finite element modeling of asymmetric gear teeth is presented. This simulation should be helpful in the design and manufacture of asymmetric gears.

Face gear drives have many advantages over other cross axis transmissions especially in high performance applications. The lack of published design experience and design standards make their design difficult. This is mainly due to the complex geometries and to the lack of practical experience. For these reasons face gears have not been used for long. This work is aimed at investigating the behavior of a face gear transmission considering contact path under load, load sharing and stresses, for an unmodified gear set including shaft misalignment and modification on pinion profile. The investigation is carried out by integrating a 3D CAD system and a FEA code, and by simulating the meshing of pinion and gear sectors with three teeth, using contact elements and an automated contact algorithm. The procedures followed to create the 3D models of teeth in mesh are described and finite element analysis results discussed showing the differences between unmodified, modified and misaligned teeth. Results show the influence of load on theoretically calculated contact paths, contact areas, arc of action and load sharing. The differences with respect to the ideal case are sometimes remarkable. Further developments are discussed.
