滚齿机上实体滚切中硬齿面齿轮是当前具有重大经济意义的一项加工技术。本文介绍了对硬度为HRC36～46(HB332～436)中硬齿面齿轮滚削力的测试结果,分析了各项切削条件变化对滚削力的影响,指出:HRC36～46中硬齿面齿轮的滚削力一般低于同材质软齿面齿轮的滚剖力,在此范围内,不同硬度齿面齿轮滚削力的变化幅度不大,但是,中硬齿面齿轮滚削力的梯度值大大超过同材质软齿面齿轮滚削力的梯度值,因此,滚切中硬齿面齿轮时更应注意滚齿过程的动载特性。测试结果表明:在合理的削切条件下,在普通滚齿机上实体滚切中硬齿面齿轮是完全可能的。
Hobbing machine solid rolling gear in the hard surface gear is currently a major economic significance of a processing technology. In this paper, the test results of the gear hobbing force on the hardened gear with hardness of HRC36 ~ 46 (HB332 ~ 436) are introduced. The influence of various cutting conditions on the rolling force is analyzed. It is pointed out that the hardened gears of HRC36 ~ 46 Of the rolling force is generally lower than that of soft gear with the same material surface rolling force, in this range, the gear hardness of the gear surface hardness of the change is not large, but the gear hardness in the hardened gear gradient value Which greatly exceeds the gradient value of the gear hobbing force of the soft gear with the same material. Therefore, the dynamic load characteristics of the gear hobbing process should be noticed even when hobbing the hard gear. The test results show that it is entirely possible to roll the hardened face gear on a conventional gear hobbing machine under reasonable cutting conditions.
