圆柱齿轮的装配误差对齿轮工作性能的影响分析

为了更加准确的研究齿轮在工作过程中的摩擦、磨损、振动、噪声、传动速度的稳定性等工作性能,需要对齿轮的工作条件进行分析.本文通过分析齿轮系统在制造、装配过程中始终存在误差的特点,对安装齿轮的齿轮箱中的相关零件及其装配关系进行了总结,建立了误差模型,通过坐标变换,推导出齿轮齿廓曲线实际工作时的切向和法向方程,获得了齿轮副工作过程中影响工作性能的压力角、基节、公法线、重合度等参数状况,明确了装配误差对齿轮传动的重要意义,为齿轮副的设计、制造、装配、检测提供了理论依据.

The Influence of Assembling Error on Working Performance of Cylinder Gear

The manufacture and assembling error of the gear system was analyzed,the correlative parts and assembly relation in gear case was summarized,and error model was set up.Tangential and normal equations of gear curve when gear works was derived by coordinate transform,the parameters that influence the working performance of gear when the couple of gears are working were gained,including pressure angle,base pitch,common normal,contact ratio etc.It provide theoretic reference for the designing,manufacture,assembly,detection of gear.
