Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...

本文应用平面啮合原理精确设计各种非渐开线齿轮滚刀的基本蜗杆，提出并应用啮合线的投影原理从工件齿轮端截面的啮合线直接求得刀具蜗杆的端面齿形，而不必求出媒介齿条的齿形，方法很简单，还从啮合线的投影原理简明而形象地证明了一对螺旋齿轮直接啮合过程的啮合线是一条垂直于齿向的平面曲线。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.
