包络面

It was found that the layer surface discharged owing to the inproper assembly, and flashover occurred with the voltage rise.

发现装配不当会导致包封层发生表面放电现象，进而在较高电压下引发沿面闪络。

Finally, the analysis results of assembly interference and assembly clearance show that the numerical models established have high degree of precision. That can be used as a reference for the profile of cutter and the virtual design of double-roller enveloping hourglass worm reducer.

最后的装配干涉和装配间隙分析结果表明，建立的数字化模型精确度很高，可以为加工蜗杆时刀具廓形的设计，无侧隙双滚子包络环面蜗杆减速器的虚拟设计等后续工作提供参考依据。

The content of this research is as follows: The structure and the work principle of this worm gearing have been introduced.

主要内容如下：阐述了双滚子包络环面蜗杆传动的结构和传动原理。

A gearing in which each element partially encloses the other is, of course, a double-enveloping worm gearing.

1传动装置，其中每个元素部分，周边有其他的，当然是双包络环面蜗杆传动。

Based on the gear geometry of the double enveloping hourglass worm gearing, the tooth surface of the wheel, which is composed of the so-called the original and new contact surfaces, is derived.

基于齿轮几何形状的双包络环面蜗杆的齿面的车轮，后者是由所谓的原始的和新的接触面，导出。

The double-enveloping hourglass worm gearing is one kind of mechanical transmission drivers, which is developed by China and Japan firstly and is used widely in national defense and civil producing industries.

平面二次包络环面蜗杆传动是由我国和日本率先研究成功的一种机械传动方式，在国防和民用工业领域内得到大量的应用。

The results provide theoretical guide for reasonable selecting of geometric design parameters of double-roller enveloping hourglass worm gearing.

所得结果有助于合理选择双滚子包络环面蜗杆传动的几何设计参数。

TI worm drive is the drive style consisted of involute helical gear and hourglassworm enveloped by the gear.

TI蜗杆传动是由渐开线斜齿轮及其包络的环面蜗杆组成的一种传动方式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
