齿形

The results showed that the drive efficiency of the worm helical gear can be improved a lot, which nearly reach to the level of the worm and wheel drive, presently, this show us a beautiful prospect of the engineering application of the worm helical gear drive.

结果表明，通过斜齿轮的齿廓修形，可以使蜗杆斜齿轮的传动的效率得到提高，接近甚至达到蜗杆蜗轮传动的传动效率，从而为蜗杆斜齿轮传动的工程应用打下了良好的基础。

Based on the acentric relief principle, a new method of accurate relief grinding is presented for making Archimedes hobs.

应用齿轮滚刀的偏置构形原理，提出了齿轮滚刀齿侧面精密铲磨的一种新方法，并用算例验证了模型的可靠性，为制造高精度滚刀提供了可靠的理论依据。

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。
