摘要

摘要: 为了制造出高精度硬齿面斜齿面齿轮和获得抛物线传动误差并改善啮合性能,对采用碟形砂轮加工双向修形的斜齿面齿轮的磨齿方法进行了研究。设计了渐开线失配的碟形砂轮齿面,分析了碟形砂轮磨削斜齿面齿轮的展成原理,根据展成原理和用渐开线失配的碟形砂轮并改变砂轮的运动,推导出双向修形斜齿面齿轮的齿面方程。给出了双向修形斜齿面齿轮的齿面计算和接触分析实例,结果表明:理论齿面的最大齿面误差为5.98×10-4μm,采用碟形砂轮加工双向修形斜齿面齿轮的磨齿方法是可行的,获得了斜齿面齿轮抛物线传动误差,避免了边缘接触并改善了斜齿面齿轮的啮合性能。

Abstract: A method of tooth grinding for double crowned face gear with helical pinion machined by using grindingdisk was studied in order to manufacture highly precise hardened face gear with helical pinion and obtain parabolictransmission errors and improve meshing performances.The surface of grinding disk with mismatched involute wasdesigned; the generation theory of helical face gear abraded by grinding disk is analyzed, deducing the tooth surfaceequation of double crowned face gear with helical pinion based on the generation theory, the grinding disk with mismatch involute and modification of the grinder movement.A tooth surface calculation and contact analysis exampleof double crowned face gear with helical pinion was represented and the results show that the maximum error of thetheoretical tooth surface of face gear is 5.98×10 -4 μm, the grinding and crowning method is feasible and the parabolic transmission is obtained, avoiding edge contact and approving meshing performances.
