上篇(一)中的图1a是1700滚筒飞剪机,i_(平均)=1,用户巳提出改造要求。为此应用上篇的原理将对该飞剪进行改造,其要点为:1)新设计具有最佳剪刃半径的螺旋剪刃滚筒;2)对增加匀速非圆齿轮系统等进行分析计算。现将其要点、计算结果,以及验算情况分述如下。一、设计螺旋剪刃滚筒的要点由上篇知,旧式滚筒直径的设计思想已经落后,结构笨重,惯量大,不能与匀速系统配套;另外基本定尺范围较宽,不大合理,定尺规格与装机容量无法协调,所以须设计两套滚筒(机头)。据根上篇的方法,经计算,确定
Figure 1a in Part 1 (a) shows a 1700 roller shears, i_ (average) = 1, and the user has requested modifications. To this end, the application of the principle of the first chapter will be the transformation of the flying shear, the main points are: 1) the new design with the best cutting edge radius of the spiral shear roller; 2) to increase the uniform non-circular gear system analysis and calculation. The main points are now, the calculation results, as well as checking the situation as follows. First, the design of the spiral cutter blade points from the previous article, the old drum diameter design ideas have lagged behind, the structure bulky, inertia, and uniform system can not be matched; other basic ruler range wider, not reasonable, size specifications And the installed capacity can not be coordinated, so we must design two sets of drum (nose). According to the root of the article, after calculation, to determine
