超声振动研齿对齿面加工质量的影响研究
|
摘要
选取齿数为7/37和8/41两对准双曲面齿轮作为实验对象,在改造过的滚动检查机Y9550上进行齿轮的超声研磨加工,超声振动频率16 kHz,超声研磨时间3 min。然后由JD45+测量机测试超声研齿前后齿面上45个点的偏移误差,再通过齿长或齿高方向的齿面误差分别计算出螺旋角或压力角误差。最后对比振动加工前后的齿面误差、螺旋角误差和压力角误差,研究结果表明,超声振动研齿能在一定程度上消除齿轮的齿面误差,改善齿轮的接触区位置与形状,提高齿轮的齿面平滑度,提高齿轮的加工质量,但也不能够进行过度研磨。
Two pairs of hypoid gears with 7/37 and 8/41 teeth are selected as experimental objects. The ultrasonic lapping of gear is carried out on the modified rolling inspection machine Y9550,ultrasonic vibration frequency is 16 kHz,ultrasonic grinding time is 3 min. Then the JD45+ measuring machine is used to measure the deviation error of 45 points on the tooth flank before and after ultrasonic lapping,and then the helical angle or pressure angle error are calculated by the tooth flank error in the direction of tooth length or tooth height. Finally,the tooth flank error,spiral angle error and pressure angle error before and after vibration processing are compared. The results show that ultrasonic vibration lapping gear can eliminate gear flank error,improve the position and shape of gear contact area,improve gear tooth flank smoothness,improve gear machining quality,but also can′t be excessively lapping.
