摘 要: | 为了改善斜齿轮副啮合传动性能,提出了应用四阶传动误差函数曲线,采用数控加工展成斜齿轮.利用抛物线齿廓的产形齿条与圆柱齿轮啮合推导小轮齿面方程.采用假想小轮的方法推导了四阶齿线修形大轮齿面数学模型.根据两齿面在啮合中连续相切条件,建立了含有误差的轮齿接触分析模型(TCA).仿真结果表明:该设计降低了接触印痕对安装误差的敏感性,相邻两个啮合周期的啮合转换点处,传动误差曲线的切线夹角接近180°,降低振动及冲击.

Abstract: | In order to improve the meshing characteristics of helical gears,the fourth order transmission was developed by CNC process.The mathematical model of pinion surface was generated by the imaginary rack cutters with a parabolic curve profile modification,then the derivation of gear surface was performed by a imaginary pinion.The tooth contact analysis which was also considered the assemble errors,was established on the conditions of continuous tangency of two contact surfaces.The simulation shows:the design of helical gears decreased the sensitivity of bearing contact to errors;there is a separation angle that is equal to 180° possibly of tangent line of transmission errors in the point of two meshing cycle;using the tooth profile modification with parabolic curve,the vibration and impact also can be reduced by a predesigned fourth order transmission curve. |
