“…Wu and Tsai 1 conducted the finite element (FE) contact analysis for crossed conical gears under one type of optimized line contact design. Song et al 2 performed FE contact analysis to study the impact of geometric and manufacturing parameters on the tooth root stress, transmission error, mesh stiffness, and other mesh behaviors for skewed beveloid gears. Yang and Wang 3 used ANSYS to analyze the contact force of spiral bevel gear and obtained the distribution of contact force.…”

Using minimum potential energy theory and slicing method, a computational approach to calculate the magnitude and distribution of contact force for paralleled beveloid gear pair was proposed in this article. The theoretical tooth contact model was built based on spatial gearing theory to calculate the mesh parameters including the coordinates, normal vectors, and equivalent radius for meshing points. Then, the analytical contact force model of paralleled beveloid gear pair was derived based on minimum potential energy theory. Finite element contact analysis was conducted to verify the proposed model. Finally, the influences of macro-geometry design parameters on the contact force distribution were investigated. Results show that the pressure angle has a limited influence on the contact force distribution. The increase in helix and cone angles will observably increase the asymmetry of contact force distribution as well as the fluctuation of contact force distribution for a single tooth. A good correlation was obtained between the proposed analytical model and the finite element model for the distribution and magnitudes of contact force.

For the beveloid gears with intersecting axis and crossed axis coexisted in the marine gearbox with small down angle, contact analysis of the meshing gear pair taken the assembly error into consideration is proposed based on the nonlinear finite element analysis software Abaqus. Considering the central distance error, axial position error and the angle error, the FE model of beveloid gear pair with intersecting axis and crossed axis were established, respectively, and the tooth contact stress, the maximum influence factor and transmission error were calculated. The effects of these errors, the central distance error, axial position error and the angle error on the contact characteristic were discussed.

“…However, compared to parallel and other type of non-parallel axis gears, very limited effort has been directed at the dynamic analysis of this type of gearing systems used in marine transmissions. Recently, there have been extensive studies performed on the tooth surface geometry design and contact characteristics for beveloid gears [1][2][3][4] . And some dynamic analysis for the crossed beveloid gear pair were investigated [5,6] .…”

Dynamic modeling of beveloid gears is less developed than that of spur gears, helical gears and hypoid gears because of their complicated meshing mechanism and 3-dimsional dynamic coupling. In this study, a nonlinear systematic coupled vibration model is created considering the time-varying mesh stiffness, time-varying transmission error, time-varying rotational radius and time-varying friction coefficient. Numerical integration applying the explicite Runge-Kutta formula and the implicit direct integration is used to solve the nonlinear dynamic model. Also, the dynamic characteristics of the marine gear system are investigated.
