摘　　要：以某公司易维护SL1000型采煤机摇臂传动系统的末级齿轮为例,运用有限元法分析了正常齿面模型和3种不同程度齿面磨损模型在一个啮合周期内轮齿啮合的运动状态、齿面接触有效应力等。以Hertz理论为基础,验证了有限元法的正确性。通过仿真结果分析,得到不同位置、不同程度齿面磨损对低速重载齿轮啮合传动、齿面接触有效应力的影响。Taking a company＇s easy maintenance SL1000 coal winning machine end gear of arm transmission system for example.Using the finite element method to analyze the tooth mesh motion state,effective stress principle of tooth surface contact,etc in a meshing cycle of normal tooth surface model and three kinds of different degree of tooth surface wear model.On the basis of the theory of Hertz,the correctness of the finite element method is validated.By analyzing the simulation results,the influence of the with a different location,different degree of tooth surface wear on gear meshing transmission of low speed and heavy loading,tooth surface contact effective stress is got.
