In this paper, the plane double enveloping worm has been researched. The motion equations have been built of it. The states of motions and victories and forces of the worm engaging point were been analysis.

本文以平面二次包络环面蜗杆传动为主要研究对象，建立了平面二次包络环面蜗杆传动的运动学分析模型，分析了平面二次包络环面蜗杆传动啮合点的运动状态、啮合点各方向的速度、各方向上啮合力的分力。

On the condition of "many-head" and "small drive ratio",the plane double enveloping hourglass worm can not settle the problem of undercutting and sharpening simultaneously.It has devoted to a new type hourglass worm_sphere double enveloping hourglass worm.

考虑到平面二次包络环面蜗杆传动在多头小传动比条件下根切与齿顶变尖的矛盾很难同时解决且啮合性能较差，介绍了一种新型环面蜗杆传动——球面二次包络环面蜗杆传动。

The features to evaluate the tooth contact quality such as the location of the contact point on the tooth surface, clearance between the meshing tooth surfaces, curve of the transmission error and the path of the contact point are investigated. The accurate geometric representation with non-uniform rational B spline of the worm and the wheel tooth surface is presented then the corresponding program is developed.

根据平面包络环面蜗杆传动的创成方法，建立了包含加工误差的蜗杆和蜗轮的齿面方程，分析了平面包络环面蜗杆传动和平面二次包络环面蜗杆传动的刚性啮合特性如误差对接触点的位置、齿面间隙、传动误差曲线和接触点在齿面上的轨迹的影响。

Furthermore,we verify the good contact state with section diagrams in the virtual reality entity of the involute helicoid double enveloping worm gear pair.

并在进一步完成的"渐开面二次包络环面蜗杆副的虚拟实体"中，以断面图检验了其良好的啮合状态。

Gone are any covers of pop standards, gone are the studio pros, gone is the enveloping lushness that made Come Away with Me so easy to embrace, something that Not Too Late is most decidedly not.
