(一)引言差动滚床的机构和工作法,虽然国内外出版的书刊多有说明,但是各有详略,很少作综合的研究;而且对于各种分齿法,总是一法一说,很少有统一的观点,一贯的说法。以致前后不一,头绪纷繁,初学读之,无法融会贯通,掌握原则。本文目的,即在针对上项缺憾,作大胆的解答。首先建立「虛齿数定理」和「齿数(虛实)结合定理」,提供一种新的分齿法的理论武器。再运用这一武器,对现有的八种分齿法,逐一说明其计
(I)Introduction The mechanism and working methods of differential roller-rolling machines, although publications published at home and abroad have many explanations, each has its own details, and few comprehensive studies have been conducted; Say, there are very few unified views and consistent arguments. Inconsistent and inconsistent, there is a lot of clues, beginners read it, can not be integrated, master principles. The purpose of this article is to make bold answers to the above shortcomings. First, we established the “Theory of Virtual Numbers of Teeth” and the “Combination Theorem of Teeth Numbers (Imaginary and Real)” to provide a new theoretical weapon for the method of dividing teeth. Then use this weapon to explain the existing eight kinds of division methods one by one.
