【摘要】 随着科学技术的不断发展和工业自动化趋势的日益加剧,对于高性能重载齿轮的需求量大大提升。重载齿轮需要在复杂的工况和恶劣的工作环境下承受很大的交变载荷及摩擦力,所以相应的重载齿轮钢必须具有良好的接触及弯曲疲劳强度,即表面硬度、强度高,心部韧性好,同时硬化层分布合理,保证表面和心部有良好的强韧性配合。本文针对重载齿轮钢的性能特点,综述了国内外学者对重载齿轮钢的强化技术及机理、接触疲劳分析、寿命预测三个方面的研究现状,从实际应用的角度出发对研究内容进行总结,并对此类研究中涉及到的新方法、新手段进行了思考与展望。更多还原

【Abstract】 With developing of science technology and the trend of industrial automation boiling up,the demand of heavy-duty gear is increasing.Heavy-duty gear needs bearing heavy alternating load and friction force in a complicated and severe work environment,so the steels of heavy-duty gear must have high strength of contact fatigue and bending fatigue,meaning high surface hardness,strength and core toughness.Hardening layer’s distribution is also important to ensure the coordination of surface and core.In this paper,heavy-duty gear steels’ reinforcing methods,contact fatigue analysis and life prediction have been summarized.From the point of practical application,this paper sum up research contents and give the thought and prospection of new methods and technology involved.更多还原
