摘要
为了降低特定工况下减速箱的噪声特性,找到相对最佳的渐开线斜齿轮修形方式,该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。分析了经过短齿廓修形后的减速箱声功率级在转速500~2000 r/min之间显著下降的原因,并对经过短齿廓修形后的减速箱声功率级在2500 r/min和3000 r/min时并未明显下降的原因做了解释。最后根据减速箱声功率级在转速500~2000 r/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。
In order to reduce the noise characteristics of the gearbox under certain working conditions,a relatively optimal involute helical gear modification method was found.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 sound power 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.The reason why the sound power level of the gearbox after short profile modification has decreased significantly from 500 r/min to 2000 r/min is analyzed.And the reason why the sound power level of the gearbox after short profile modification has not decreased significantly at 2500 r/min and 3000 r/min is also explained.Finally,according to the average reduction of the sound power level of the reducer between 500 r/min and 2000 r/min,it is considered that the maximum reduction of the sound power 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.
