    This article discovers several characters possessed while the helical gear is engaged with its counterpart rack. It's clearly pointed out that the engagement of helical gear with its counterpart rack belongs to line-contact mesh. Their surface of the action and line of contact depend completely on the obligue angle, normal profile and relative-io-pitch-plane position of the counterpart rack, but not on the pitch diameter of the helical gear. At the same time, the concrete methods which solve conjugate profile of the helical gear and define the tooth profile of the hob basic worm. Thus some principles, such as the principle of the envelope line, the principle of the common normal etc, which are applied to plane engagement can be applied to space engagement-the engagement of crossed helical gear pair. As a result, the process solving problems is simplitied to a certain degree.

    本文揭示了具有任意齿形的斜齿轮与其产形齿条啮合过程中所存在的若干特性。明确指出,斜齿轮与其产形齿条(斜齿条)的啮合属线接触啮合。它们的啮合曲面和瞬时接触线的形状完全取决于产形齿条的斜角、法向齿廓及其对节平面的相对位置,而与斜齿轮的节圆直径无关。 本文还提出了用斜齿轮的产形齿条求解其共轭齿廓和确定滚刀基本蜗杆齿形的具体方法。这样,研究平面啮合的一些基本原理,如包络线原理、公法线原理等,即可用于空间啮合(交错轴斜齿轮副啮合)中,从而在一定程度上简化了解题过程。

    A theory of hobbing involute conical gears on a hobber with a horizontal feed motion is described in the light of the gear engagement principle.The relations among some important parameters of the imaginary rack shaper cutter and the generated gear are analyzed,and the design method of a change speed train mainly composed of intersected involute conical gears is considered in detail.It has many special advantages such as many speed degrees only with a few gears,adjustable gear clearance by changing position of the gear along with their axes respectively.Because in designing this kind of train it is very important how to minimize the volumn and size and how to maximize the changable speed degrees and the difference between the highest degree and the lowest degree.A practical method is provided to control some key parameters to reach these goals.The present theory is proved correct and the method is shown practical by tests of a sample change speed train.

    After removing hob on CNC helical bevel gear milling machine with bevel gear with helical tooth, it machined not only the bevel gears or double curved surface gears, but also the cylindrical gears as well. While the cutter rotating and moving at one time, and forming the medium gear, gears machining was implemented with this method. Therefore, the coordination system that fixed on the medium gear and the cutter was introduced. When cutter rotates about x axis of the coordination system, the cone was formed, and the tooth of cylindrical gears was the envelope formed when the medium gear moving and the cylindrical gear rotating. The taper surface equations of the taper gears, tooth-coupling equations of bevel gears with helical tooth and the tooth surface equations were deduced at the same time.

    利用螺旋锥齿轮数控铣齿机,取消滚刀不但可以加工圆锥齿轮和准双曲面齿轮,还可以加工圆柱齿轮。该方法是通过刀盘一面旋转,一面平移可形成产形齿条(媒介齿条)的原理来实现的。为此,引入产形齿条固连坐标系和刀盘固连坐标系。当刀盘绕固连坐标系x轴旋转时,形成圆锥面;斜齿圆柱齿轮则是圆锥产形齿条作平移,圆柱齿轮作转动时的包络面。同时,导出了该方法的圆锥的锥面方程,斜齿轮啮合方程和齿面方程。
