活齿传动齿形综合的第Ⅱ类反解问题及相似变换法

本文研究活齿传动齿形综合的第Ⅱ类反解问题。综合方法采用以主从动轮理论廓线间的基本关系式为基础的相似变换法。从有利于工业化生产方面考虑,有选择地推导了渐开线等几种齿形的理论廓线及实际廓线。简略分析了几种齿形在活齿传动技术中的运用前景。

THE DESIGN OF A NEW OUTSIDE TYPE CONJUGATE CAMS FOR SHEDDING MECHANISM

In the usual shedding mechanism of a weaving loom, the conjugate type of cams can be designed precisely according to any regular pattern sequence of heald frame motion to suit the weaving technological requirements. As this mechanism is also quite simple, with smaller cam size and better technological function, it is therefore very important and worthwhile to study this type of conjugate cams. In this paper, we try to analyze the defects of the traditional and some abroad type outside conjugate cams shedding mechanism, and propose a new improved design of this type of conjugate cams and then work it out finally.
