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.

Practical Engineering Problem

Gears are widely used in many practical engineering to transmit torque. In the process of meshing, contact stress will be produced which causes pitting. Shock becomes more and more serious with the increase of pitting and the probability of failure of meshing gears increases. Contact stress analysis is necessary and important to increase the reliability of gear transmission. In this paper, a fuzzy Hertz approximate optimization method and finite element method are used to deal with a practical engineering problem.
