摘要

三峡升船机齿条寿命试验齿轮箱为低速重载四级传动,试验过程中需频繁快速换向运转,由于轮系啮合侧隙、轴系弹性扭转变形以及轮齿弹性变形等因素的影响,会导致齿轮箱运转性能的变化,尤其是换向期间输出转速和转矩的波动。为了分析对齿轮箱传递性能的影响,分别建立了轮系啮合侧隙和轴系弹性扭转变形对转速影响的计算模型,对齿轮箱换向过程中的输出转速进行了计算,并与试验实测的齿轮箱输出转速进行了对比分析,实现了对计算模型和试验数据准确性的互相验证。

Abstract

The gearbox of rack test for the Three Gorges ship lift is low speed heavy duty four stages transmission,and need frequent fast reversing operation in the process of test,due to the influence of the gear meshing backlash,elastic torsional deformation of shaft and elastic deformation of gear tooth and other factors,the operation performance of gearbox will be changed during reversing process,especially the output speed and torque. In order to analyze the influence on the transmission performance of gearbox,the calculation models of the influence of the gear meshing backlash and the elastic torsional deformation of the shaft on the rotational speed are setup respectively,the output speed of the gearbox in the reversing process is calculated and compared with the output speed of gearbox measured by experiment,which verifies the accuracy of the calculation model and the test data.
