摘要:
 以某偏航齿轮箱的第一级行星传动为研究对象,重点对齿向均载进行研究。首先,构建一种阶梯型销轴和轴套的结构方案,提高变形补偿的能力。其次,给出了行星新型柔性销轴和轴套的挠度与转角计算公式,验证了计算公式的准确性。最后,使用ANSYS和Romax软件对阶梯型销轴和异形轴套进行实例分析。分析结果显示:在考虑行星架轴变形的条件下,相较于Montestruc柔性销轴,阶梯型销轴和新型轴套在相对于轴线上的变形角度减小约16%,随着销轴颈部直径的增大,其变形角度增大,接触面的平均等效应力减小;随着销轴颈部长度的增大,变形角度先减小后增大,接触面的平均等效应力先增大后减小;齿向的最大接触应力减小约5.5%,齿宽方向上载荷分布相对均匀;齿轮齿根处的最大弯曲应力减小约8.5%;在一定范围内,随着输入转矩的增大,阶梯型销轴和新型轴套对于降低齿面最大接触应力的效果变好。以上数据表明,阶梯型销轴配合新型轴套具有良好的均载性能,可为行星传动的均载优化提供设计参考。
Abstract:
 Taking the first stage planetary transmission of a yaw gearbox as the research object,this study focuses on investigating load sharing along the tooth width.Firstly,a structural scheme involving stepped pin shaft and sleeve is proposed to enhance deformation compensation capability.Secondly,the formulas for calculating the deflection and rotation angle of the planet’s new flexible pin shaft and bushing are provided,and the accuracy of these calculation formula is verified.Finally,ANSYS and Romax software are used to analyze the stepped pin shaft and special shaped bushing.The analysis results show that,under the conditions considering the deformation of the planet carrier shaft,compared with the Montestruc flexible pin shaft,the deformation angle of stepped pin shaft and the new shaft sleeve relative to the axis is reduced by approximately 16%.As the neck diameter of the stepped pin increases,the deformation angle increases,while the average equivalent stress on the contact surface decreases.As the neck length of the pin increases,the deformation angle first decreases and then increases,and the average equivalent stress on the contact surface first increases and then decreases.The maximum contact stress in the tooth direction is reduced by about 5.5%,indicating a more uniform load distribution in the tooth width direction.The maximum bending stress at the root of gear tooth is reduced by about 8.5%.Within a certain range,as the input torque increases,the effectiveness of the stepped pin shaft and new sleeve in reducing the maximum contact stress on the tooth surface improves.The above data show that the stepped pin shaft combined with the novel sleeve has excellent load sharing performance,providing valuable design references for optimizing load sharing in planetary transmissions.
