Effects of Boundary Condition and Helix Angle on Meshing Performance of TI Worm Gearing


With helix angle chosen as parameter, the criterion for the existence of meshing boundary line on the surface of TI worm gearing is derived.


Results show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines.


If the helix angle is equal to or slightly smaller than the bigger angle, which makes two meshing boundary lines superpose, a preferable meshing performance is obtained.


In the following sections, some problems are discussed, such as the assembly form, the construction characteristics, the correct meshing condition, the continuum transmission condition and so on.


A novel micro drive mechanism called the microelasticmeshingwheel is presented in this paper.


The algorithm in this paper presents a solution to the corresponding principles of the vertices on each layer and between layers after meshing the start and the end key frames.


According to differential geometry and gear geometry, the equation of meshing for small teeth difference planetary gearing and a universal equation of conjugated profile are established based on cylindrical pin tooth and given motion.


The correct meshing condition, contact line, contact ratio, calculating method for pin tooth's maximum contact point are developed.


Investigation on the theory of conjugated meshing is carried out when the tooth difference numbers between pin wheel and cycloidal gear are 1, 2, 3 and 1, respectively.


The correct meshing condition for cycloid pin wheel gearing is provided, and the contact line and the contact ratio are also discussed.


A hybrid meshing scheme was used with hexahedral cells in the near blade region and tetrahedral and pyramid cells in the rest of the domain.


Secondly, the technique of covering finite elements for problems with movement has been presented; namely, when the place of testing point moved, the meshing data will be produced automatically to avoid remeshing and distortion of the mesh.


Combination of the grid remeshing method and the snapper technique made the valves move smoothly.


The loads on meshing teeth of internal ring gear are applied according to the contact ratio and the loadsharing coefficient.


Meshing of such models, although not quick, can be done without much difficulty.


Finite element modeling and meshing of the lap joints having 25.4 and 50.8 mm adhesive overlap lengths were completed.


A single global meshing strategy for finite element analysis is described that includes focused radial meshes at every material junction to accurately capture crack tip and material junction singularities.


Guidelines for meshing parameters (such as element density and distribution) are discussed on the basis of convergence studies of stress distributions along interface junctions, crack opening displacements and crack driving forces along interfaces.
