论文部分内容阅读
本刊过去曾经刊登不少有关齿轮计算方面的文章,同时“机械工人活叶学习材料”也出版了不少有关这方面的材料,但是也于读者们没有及时的腾到这些书籍和刊物,因而我们还经常收到读者的来信,要求刊登齿轮方面的文章。我们认为,齿轮在机械工厂中应用的范围很广,各工种工人同志都需要了解这方面的知识,因而决定再从本社出版的“金属切削工人手册”中选出一部分陆续登出。又因齿轮的范围很广,难以详细刊登,现在仅就标准正齿轮、内齿轮、伞齿轮、螺旋齿轮、蜗杆与蜗轮等的各部尺寸计算等陆续登出,供同志们作为资料参考。
In the past, we published quite a number of articles on gear calculation. At the same time, Mechanical Workers’ Leaf Learning Materials also published quite a lot of materials on this subject. However, they did not promptly release these books and periodicals so readers We also often receive letters from readers, asking for articles on gears. In our opinion, gears are widely used in machinery factories. Workers of all trades and occupations are required to know this knowledge. Therefore, they have decided to roll out some of the "Metalloop Workers’ Manuals published by CCS in succession. Due to the wide range of gears, it is difficult to publish them in detail. Now, only the sizes of various standards such as standard spur gears, internal gears, bevel gears, helical gears, worm gears and worm gears are checked out for reference by comrades.
