为了提高弧齿锥齿轮的研齿质量,获得对研齿运动的更好控制,本文根据齿轮啮合理论,采用轮齿接触分析(TCA)的方法对研齿时齿轮运动的V、H、J三轴进行了运动分析,建立了数控研齿机的运动模型,并通过实验进行了验证。该研齿模型与传统的研齿机相比,可以对V、H、J三轴的运动进行精确控制,从而能更好地控制啮合齿面的研齿质量。

In order to improve the lapping quality of spiral bevel gears and to acquire the well control of the motion of gear lapping,the three axial movements of spirals bevel gear lapper,controlled by the V,H,J axis were analyzed according to gear theory and tooth contact analysis(TCA) technique.The computer numerical control movement model of spiral gear lapper was established.The experiment verified the accuracy of the model proposed in this paper.Compared with the traditional gear lapper,the new gear lapper model can accurately control the movement of V,H,J axis.Thus,it can well control the quality of meshing surface of the lapped gear.
