参数化修形的直齿轮副啮合性能研究
|
摘要
齿轮的参数化修形设计可以快速、有效地改善轮齿啮合性能。在UG中建立全参数化的直齿圆柱齿轮模型,针对某一工况进行参数化的齿廓与螺旋线联合修形,在Hypermesh和Workbench中对其进行有限元仿真,获得不同修形情况的齿轮啮合特性。对比仿真结果可知,针对同一工况,选择合适的修形方式、修形参数值可以明显改善啮合效果。同时,通过齿轮台架试验,对比修形前后的齿轮振动数据,发现经过修形的齿轮振动特性明显优于未修形齿轮。结合仿真与试验结果分析可得,螺旋线鼓形修形对于齿面偏载有较好的改善效果;齿廓修形能明显改善轮齿间的载荷分配;综合齿廓与螺旋线修形可以快速得到最佳修形方式及修形量,缩短研发周期。研究为实际工程提供了重要理论参考。
The modification design based on parametric gear model can improve the meshing performance rapidly and effectively. Parametric tooth profile and tooth helix modification of the fully parametric spur gear are carried out in the UG. The finite element simulation is performed by using Hypermesh and Workbench to obtain the gear meshing characteristics under different conditions. The simulation results show that for the same working condition,choosing the proper method of modification and modification parameters can obviously improve the meshing effect. At the same time,through the gear bench test,comparing the gear vibration data before and after modification,it is found that the gear vibration performance of the modified gear are obviously better than that of the unmodified gear. By analyzing the results of simulation and experiments,the modification of tooth axial of drum shape has a better effect on the partial load of tooth flanks and the profile modification has a significant effect on the improvement of load distribution between teeth. The optimum modification method and the amount of modification can quickly obtained by the parametric modification of gear which short the R & D cycle and provide an important theoretical reference for practical engineering.
