| 目的汽车齿轮减速箱降噪方法本文基于专业的齿轮修形软件Kisssoft和多学科一体化软件LMS Virtual Lab，根据短齿廓修形可以改变渐开线斜齿轮的端面、轴向重合度的原理，比较了未修形和经过不同短齿廓修形方式达到特定重合度后的渐开线斜齿轮减速箱声功率级的大小。结果分析了转速在500r/min~2000r/min之间渐开线斜齿轮经过短齿廓修形后减速箱声功率级显著下降的原因，同时在2500r/min、3000r/min时经过短齿廓修形后渐开线斜齿轮减速箱声功率级并未明显下降。结论最后根据减速箱声功率级在500r/min~2000r/min之间的平均降幅，认为通过齿形鼓形修形使得渐开线斜齿轮的端面、轴向重合度分别为1.516、0.864时，减速箱声功率级降幅最大，降噪效果最好。 |

| Objective Reducing noise of automobile gearbox. Methods Based on the professional gear modification software Kisssoft and multi-disciplinary integration software LMS Virtual Lab, according to the principle that short gear profile modification can change the transverse contact ratio and overlap contact ratio of involute helical gears,the magnitude of the weighted total sound pressure level of involute helical gears reducer without modification and after different short gear profile modification methods to achieve a specific coincidence degree are compared in this paper. Results At the same time, analyses why the unweighted sound pressure level of involute helical gears after short gear profile modification decreases significantly between 500 r/min and 2000 r/min. When the speed are 2500 r/min and 3000 r/min, the unweighted sound pressure level of involute helical gears after short gear profile modification do not decrease significantly. Conclusion Finally, according to the average reduction of the unweighted sound pressure level of the reducer between 500 r/min and 2000 r/min, it is considered that the maximum reduction of the unweighted sound pressure level of the reducer is achieved when the transverse contact ratio and overlap contact ratio of the involute helical gears are 1.516 and 0.864 respectively through the tooth drum modification. |
