摘要: 基于集中参数理论,建立了采用中间浮动构件的封闭差动人字齿轮传动系统静力学模型.通过计算载荷不均匀系数,获得了齿轮偏心误差、安装误差与载荷不均匀系数间的关系曲线,进而分析了偏心与安装误差对传动系统均载特性的影响.结果表明: 各行星轮/星轮偏心误差的初相角相同时,行星轮/星轮的偏心误差对系统两级载荷不均匀系数没有影响; 与差动级行星轮不同,安装误差引起的封闭级各星轮载荷不均匀系数不随时间变化; 差动级的载荷不均匀系数大于封闭级,且对误差较为敏感.

Abstract:

In this paper,a static model of encased differential herringbone train system with intermediate floating components is proposed based on the theory of the concentrated parameter. In this model,the curves of the eccentric and installation errors versus the load sharing factors are obtained by calculating the load sharing factors,and then the impacts of the errors on the load sharing behaviors of the train system are analyzed. The results show that ( 1) at the same initial phase angle,the eccentric errors of the planet /star gears have no influence on the load sharing factors; ( 2) unlike the planet gears of the differential stage,the load sharing factors of the star gears,which are caused by the installation errors,do not change with time in the encased stage; and ( 3) the load sharing factors of the differential stage are greater and more sensitive to the errors than those of the encased stage.

Key words: encased differential planetary train, error, herringbone, statics, load sharing
