摘要 根据直齿轮传动特点及匮油润滑理论,推导得到直齿轮干摩擦条件,运用疲劳磨损理论与有限元原理,得出无润滑油状态下齿面磨损及温度场分布的计算方法,并通过MATLAB对干摩擦磨损进行数值模拟。结果表明,转速的增大将会减小摩擦系数与磨损量,而载荷的增大会提高摩擦系数与磨损量。运用ANSYS模拟干摩擦稳态温度场,通过瞬态计算得出载荷对极限温度值的影响。 Based on the characteristics of gear transmission and the oil-lacking lubrication theory, dry friction conditions of the spur gear were obtained. By using fatigue theory and finite element principle, the methods of calculating wear of gear surface and the distribution of temperature field were obtained. Results of numerical simulation on wear in dry friction mode showed the friction coefficient and wear loss decreased with the increase in rotary velocity and increased with the increase in load. In addition, ANSYS was applied to simulate the steady temperature field in dry friction mode, and the influence of load on temperature limit was obtained by transient calculation.
