摘要

为了研究高速列车牵引电机传动系统中鼓形齿式联轴器的收缩电阻，采用几何分析方法，依据联轴器结构参数，建立了联轴器外齿表面数学模型。基于坐标变换计算了联轴器在存在轴间倾角情况下的各齿表面相对夹角与最小接触间隙；依据单齿挠曲线近似微分方程并采用载荷分配方法计算了联轴器各齿载荷与总载荷的关系；根据Hertz弹性接触理论与粗糙表面接触理论计算了实际接触面积与收缩电阻。研究表明，联轴器在齿面最小间隙为0时，轴间倾角为极值；联轴器轴间倾角越大，单齿所受载荷越大，不同齿的齿面所受载荷分布越不均匀。当电机在牵引运行状态时，联轴器实际接触面积最小约为, $0.012 m m^{2}$ ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34073181&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34073177&type=,15.49400043,2.96333337,，最大约为, $0.06 m m^{2}$ ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34074985&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34074984&type=,13.54666710,2.96333337,。联轴器总齿面收缩电阻与总力矩呈反比关系，联轴器收缩电阻在16.2~, $155.2 μ Ω$ ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34074989&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=34074988&type=,14.39333248,3.47133350,之间。研究成果可为联轴器电蚀分析提供一定的理论参考。

Abstract

In order to research the constriction resistance of the drum gear coupling of high speed EMU traction motor drive system，by using the geometrical analysis method，a mathematical model of the external tooth surface is established according to the structural parameters of the coupling. The relative angle of each tooth surface and the minimum clearance in the case of shaft inclination angle is calculated based on the coordinate transformation when there is an inclination between the shafts. Make use of the load distribution method to calculate the relationship between the load of each tooth and the total load of the coupling according to the flexural approximate differential equation of single tooth，according to the Hertz contact theory and the rough surface contact theory，the actual contact area and constriction resistance are calculated. The researches show that the inclination angle between the shafts is the extreme value when the minimum clearance of the tooth surface is zero. The greater the shaft inclination of the coupling，the greater the load on the single teeth，and the more uneven the load distribution on the tooth surface of different teeth. When the motor is in traction operation，the minimum actual contact area of the coupling is approximately 0.012 mm,2,，and the maximum is approximately 0.06 mm,2,. The total constriction resistance of the coupling is inversely proportional to the total torque. The coupling constriction resistance is between16.2 μΩ and 155.2 μΩ. The study of the constriction resistance can provide a certain theoretical reference for the analysis of the couplings galvanic corrosion in the future.
