摘要
针对目前齿轮传动系统均载特性试验未考虑齿侧间隙、轴偏心角等加工和安装误差等对均载特性的影响,文中以定轴式功率三分支齿轮传动系统为研究对象,搭建了齿轮传动系统均载特性试验台,试验台设计中,通过在轴承座处加装薄垫片实现齿侧间隙的精准调整,通过定制偏心套结构实现轴偏心角度的可控调节。为探究均载特性的影响规律,测试了不同工况下分流级与汇流级中心轮的齿根应力,并采用温度补偿应变片消除温度干扰对测试精度的影响,重点分析了负载、齿侧间隙及轴偏心角度与均载特性的关联关系。研究结果表明:汇流级齿轮的均载特性优于分流级;两级齿轮的均载效果均随载荷增大而提升;轴偏心角度对齿轮均载特性的影响显著。
The current load sharing characteristic test of gear transmission systems does not consider the influence of processing and installation errors such as backlash and shaft eccentricity angle on load sharing characteristics.To address this issue,a load sharing characteristic test bench for a gear transmission system was built for a fixed axis power tri-branching gear transmission system.The backlash was accurately adjusted by adding a thin gasket at the bearing seat,and the shaft eccentricity angle was adjusted by designing the eccentric sleeve structure.The tooth root stress of the center gears of the split and combiner stages was tested under different operating conditions to explore the influence laws of the load sharing characteristics.Temperature compensation strain gauges were adopted to eliminate the influence of temperature interference on the test accuracy.The correlation between load,backlash,and shaft eccentricity angle and the load sharing characteristic was analyzed in detail.The results indicate that the load sharing characteristics of the combiner stage are superior to those of the split stage.The load sharing effect of the two-stage gears improves as the load increases;the shaft eccentricity angle has a significant impact on the load sharing characteristics of the gears.
