摘要
圆柱斜齿齿轮在成形磨齿齿向修形加工过程中,会产生齿面扭曲,通过调整砂轮或优化多轴附加运动可以补偿齿面扭曲,但齿面精度难以达到使用要求。据此,提出了一种基于齿向修形曲线反向补偿齿面扭曲的方法,利用实际修形曲线构造的虚拟齿面下的砂轮廓形反求修形齿面,以齿面扭曲评价指标为依据,分析得到补偿后的最优砂轮廓形。最后,以一斜齿轮鼓形修形为例利用VERICUT进行仿真分析,并根据实际齿面与理论齿面间的偏差量,计算齿面扭曲量。结果表明,基于反向补偿思想补偿齿面扭曲,可以有效消减齿面扭曲,提高齿轮齿向修形精度。
During the process of forming,grinding,and modifying the tooth direction of cylindrical helical gears,tooth surface distortion may occur.Adjusting the grinding wheel or optimizing multi axis additional motion can compensate for tooth surface distortion,but the tooth surface accuracy is difficult to meet the requirements of use.Based on this,a method of reverse compensation for tooth surface distortion based on tooth profile modification curve is proposed.The virtual tooth surface constructed by actual modification curve is used to reverse calculate the modified tooth surface from the grinding wheel profile.Based on the evaluation index of tooth surface distortion,the optimal sand profile after compensation is analyzed.Finally,taking the drum shaped modification of a helical gear as an example,simulation analysis is conducted using VERICUT,and the tooth surface distortion is calculated based on the deviation between the actual tooth surface and the theoretical tooth surface.The results show that compensating for tooth surface distortion based on reverse compensation can effectively reduce tooth surface distortion and improve the accuracy of gear tooth profile modification.
