项目摘要

The damage of the gears brings the large economic loss, and has the risk of causing the accident which involves the human lives. Thus the risk management of the gears is extremely important. On the other hand, in order to decrease the energy consumption, the power transmission gear system is required to be the downsizing and the long-term reliability. To estimate the probability of damage of the gears is indispensable for this purpose.In this research, the following project was carried out for a term of 3 years since 2004 in order to apply the risk management to the design of the carburized gears.・Developing a simulation method to estimate the fatigue strength based on distribution of the inclusions.・Validation of a simulation method based on the fatigue tests of the gears.・Establishing a method for the estimation and assuring the allowable stress of the carburized gears in consideration of the probability of damage.To achieve above subjects, the various research were carried out from the broad view points, and following result were obtained.・Estimation of P-S-N curves in view of the reliability design of the carburized gears.・Quantitative evaluation of the strain near the tooth fillet by an image processing・Development of the fatigue strength simulation in the reliability design of the carburized gears.・Development of the surface durability simulation considering the distribution of the inclusions.

齿轮的损坏不仅带来巨大的经济损失，而且有引发危及生命的事故的风险。因此，齿轮的风险管理极其重要。另一方面，为了降低能耗，要求动力传动齿轮系统小型化和长期可靠性。为此，估算齿轮损坏的概率是必不可少的。本研究从2004年起，为了将风险管理应用于渗碳齿轮的设计，进行了为期3年的以下项目。・开发一种基于夹杂物分布的疲劳强度估算模拟方法。・基于齿轮的疲劳试验验证模拟方法。・建立估算和分析方法。考虑到损伤概率，确保渗碳齿轮的许用应力。为了实现上述课题，从大的角度进行了各种研究，并获得了以下结果。・考虑到渗碳齿轮的可靠性设计，推定P-S-N曲线。・通过图像处理对齿圆角附近的应变进行定量评价。・开发渗碳齿轮可靠性设计中的疲劳强度模拟齿轮。・开发考虑夹杂物分布的表面耐久性模拟。
