This researchs object is determining  the effect of modifying center distance to bending stress and contact stress on the helical gear pair based on the finite element method. And to know the safety factor on each center distance variation within helical gear pair.Gear being analyzed is one of the gears on Honda motor cycles branded Beat. To know the specification of gear, the helical gear geometry measurements were taken. Based on the results of measurements was carried out models of helical gear pair by AUTO CAD software. Then,  bending stress and contact stress analysis with finite element method on  ANSYS 12.1. Optimal center distance of gear pairs is determined by safety factors on the quasi statatis condition.From the research results can be concluded that the change of center distance can affect the bending stress and contact stress on gears and affect of security design. A safe center distance variation is 52.65 mm, 52,75 mm, 52,85mm and 52.95 mm.

To analyze the edge contact of spiral bevel gears, owing to its effect on meshing performance, batch processing is performed based on a static solver and the finite element method (FEM) because of its computational speed advantage. A series of programs automatically perform the functions of modeling, analysis, and extraction of performance indexes. Starting from the entrance meshing position to the exit meshing position, a series of models was built and analyzed to describe the whole meshing process of the gear pair. For a specific gear pair, contact and bending stresses, contact stress patterns, loaded transmission errors, contact forces, and load sharing coefficients are calculated under five different load conditions and the change rules are summarized. Edge contact phenomenon occurs as the load increases to a critical value, resulting in a sharp increase in contact stress. As the load increases, the load sharing coefficient decreases gradually and the absolute value of transmission error increases, but the fluctuation of transmission error first decreases and then increases. In addition, the effect of modules is discussed and the results show that large modulus will decrease stress, contact ratio, and edge contact, but there is a certain module to minimize the fluctuation of transmission error.

A new finite element analysis for meshing gear pair has been developed with a new element called “tooth flank film element.” The new element is a phantom element put on a tooth flank without any thickness, and enables boundary conditions for a contact problem in meshing teeth to be easily dealt with. In the present paper, contact stresses between tooth flanks of mating gear pair calculated with the proposed finite element method are compared with stresses measured with pressure measurement films. As a result, the proposed method was confirmed to be useful for evaluation of contact stress.
