Analysis of the Influence of Tooth Line Radius on the Bending Strength of Circular-Arc-Tooth- Trace Cylindrical Gear

Abstract

Research analysis of circular-arc-tooth-trace cylindrical gear transmission line deputy basic forming theory, the use of finite element discretization process to the entire gear model is simplified to only a single tooth model, using software ANSYS Workbench 13.0, reasonable determination of the boundary of model boundary width and depth, based on the Gleason cutter machining parameters, in UG/Open Grip environment, expand the influence of the bending strength of gear tooth line radius mechanism research, obtained under the pressure of a certain intensity, given the corresponding modulus, tooth number, pressure Angle, the parameters of the tooth width conditions, different change with the radius of tooth line, Finally, it is concluded that the bending strength of gear teeth changes with the change of tooth radius. Research has shown that lines to circular arc tooth cylindrical gear teeth, radius and its tooth bending strength have close relations, but not to say that the smaller the radius of the tooth trace of gear tooth, or, the greater the the tooth bending strength is better, but under the condition of a module, tooth line radius within a certain range, the bending strength of gear teeth.
