齿面综合研磨率分析与研齿性能试验

首次通过对研齿过程的轮齿接触仿真,齿面瞬时接触应力、齿面滑动系数与齿面研磨概率的研究分析,建立了齿面综合研磨率的评价指标,并进行了研齿性能试验。结果表明,准双曲面齿轮齿面中部研磨要严重一些,靠齿根稍重些,靠齿顶稍轻些,这与传动误差变化规律一致。研齿能一定程度上降低齿形、齿距误差,尤其对轮齿的实际啮合精度改善明显,振动噪声均有较大下降。

Analysis of General Lapping Rate and Lapping Experiments of Gears

We simulate the tooth contact during the lapping of gears and analyze their tooth contact stress,surface sliding coefficient and probability of contact lapping.Thus we establish the evaluation indicators of the general lapping rate of tooth surface and carry out experiments on lapping performance.The experimental results show that the central part of the tooth surface of a hypoid gear is lapped more heavily than the other parts.This is consistent with the change in transmission error.The lapping of gears can reduce tooth profile errors and tooth pitch errors to a certain degree.In particular,it can greatly improve the actual precision of gear meshing and also reduce vibration noise.
