锥齿轮的内孔加工,一般用圆柱推刀在压力机上推孔或在磨床上磨孔。由于节锥对内孔轴线有跳动量的要求,给磨孔的加工带来校正的困难。经实践,试制了磨锥齿轮内孔的夹具,见图1,使用此夹具磨削了千余件产品,全部合格。现介绍如下。 1.圆柱直径d的确定:以锥齿轮大、小端齿槽为参考,选取圆柱直径d(或按齿槽计算,也可近似选取d=2m/3,m为模数)。使圆柱放在齿槽中要高出齿槽。圆柱的长度可选齿长的2/3为宜;再将圆柱的中心钻小孔,热处理HRC58～63;最后精磨外圆。
Bevel gear in the hole processing, the general push with a cylindrical push the hole in the press or grinder on the grinder. Due to the taper hole on the axis of the amount of beating requirements, to the grinding hole to bring the difficulty of processing. Practice, the trial of grinding bevel gear bore hole fixture, shown in Figure 1, use this fixture to grind more than a thousand products, all qualified. Now introduced as follows. 1. Cylinder diameter d to determine: the bevel gear large and small end of the slot as a reference, select the cylindrical diameter d (or according to the cogging calculation, but also can be approximately selected d = 2m / 3, m is the modulus). Place the cylinder in the alveolus more than the alveolus. Cylindrical length of 2/3 optional tooth length is appropriate; then the center of the cylindrical hole drilling, heat treatment HRC58 ~ 63; finally fine grinding cylindrical.
