In the paper , first of all , it is introducetion about the circular worm gear reducer .then , it is the principles about

在论文中，首先，对蜗轮蜗杆作了简单的介绍，接着，阐述了蜗轮蜗杆的设计原理和理论计算。

Its mating gear is called a worm gear, which is not a true helical gear.

与其相配的齿轮叫做蜗轮，蜗轮不是真正的斜齿轮。

The article describes the advantages and disadvantages of worm gear drive s and the domestic and abroad research.

介绍蜗轮传动优缺点和国内外蜗轮研究现状。

Circular worm gear reducer is one of the members in the worm gear reducer family .

环面蜗轮蜗杆减速器是蜗轮蜗杆减速器的一种形式。

Involute cylindrical worm-helical gear transmission is to use helical gears to replace worm wheels in traditional worm wheel transmission so as to form a new worm transmission.

圆柱蜗杆斜齿轮传动是在传统的蜗杆蜗轮传动中用斜齿轮取代蜗轮而形成一种新的蜗杆传动形式。

The results reveal that, in some cases, the efficiency of helical gear is not as good as that of worm and wheel drive ; however, the efficiency of the worm helical gear drive in certain torque and the scope of rotational speed is still more close to that of worm and wheel drive.

结果发现虽然斜齿轮与蜗杆的传动效率在试验中不如蜗杆蜗轮传动，但是在一定的转矩和转速范围内，蜗杆斜齿轮传动的效率还是较接近蜗杆蜗轮传动。

The zymotic production by ferment cultivate and extraction from Tri-BA81 of Verticillium lecanii introduced from institute of Plant Protection of Russia, is applied to prevent five aphis.

从俄罗斯全俄植保所引入的蜡蚧轮枝菌Tri–BA81，经液体发酵培养，并经萃取、提纯得到代谢产物—蜡蚧轮枝菌素，并将其用于对5种蚜虫的毒杀作用研究。
