联轴节内齿圈齿顶高系数f_e=0.8,齿根高系数f_i=1,系短齿系列,与标准齿高内齿加工相比,缩短了啮合线长度。在避免顶切,减轻切削负荷,扩大刀具齿数选择范围等方面,都有利于加工。内齿圈的齿根圆公差范围较一般齿轮严格。一般齿轮加工对齿根圆不给严格限制,而联轴节内齿圈的齿根圆,使用中起定心作用。它与球形外齿轴套的装配情况,类似外径定心的花键套。用标准插齿刀插削这种内齿圈,既
Coupling ring gear top high coefficient f_e = 0.8, the root of the high coefficient f_i = 1, Department of short tooth series, compared with the standard gear tooth processing, shorten the length of the meshing line. In avoiding the top cut, reduce the cutting load, expanding the range of choice of tool teeth, etc., are conducive to processing. Ring gear tooth root circle of tolerance than the average gear strict. General gear processing does not give the root circle strict restrictions, and the coupling ring gear ring root, the use of the centering effect. It and the spherical outer sleeve assembly, similar to the diameter of the centering of the spline sleeve. With a standard shaper cut inserts such internal gear, both
