用编程方法解决精密滚子链轮中链轮的作图

hyfjy

没有人关心了，自己顶一下，如果有朋友用我发在一楼的小软件做成三维图并发到这个论坛上我会送上新版本的软件哦。

提示点与点之间的间隔，软件默认间隔为0.1mm，我设置改为0.01mm后，得到的文件导入CAXA中得到一团乱线 ，这是什么问题？还有就是点与点之间的间隔是控制什么精度的 ？期待回复！！谢谢附图一张就是这样的！

如图

将CAXA文件处理后，在CAD中的作图结果：分别有直线作图  和样条曲线作图 结果对比如图：发现齿顶部分不一样？？红色为样条曲线作图，白色为直线作图

回答你几个问题：
1.关于减小点之间的距离会产生乱线，是由于文件中有用科学表示法输出的数，要细心改一下，改的方法楼上几篇文章已说清楚了。
2.从文件直接导入CAD是首先要把样条线文件中的空格键及Z座标全部去除后直接导入，就能获得完全光滑的整条样条线了。
3.齿顶倒角的问题是原软件中就有的，当直接导入后是个尖角，重画操作后就有了变形，所以在新版软件中加了一个倒角。看一下前几楼的就完全知道了。
新版软件中在输出时全部用普通计数法表示，在齿的顶部加上了一个小倒角，对这二个问题就解决了。能在三维图中拉一个三维模型传上来，就可以得到新版软件哦。
加油啊。

做个三维图如下，两侧未倒角哦：

链轮除了对齿形有要求之外，在端面上要倒角或倒圆弧，要做安装的孔或轴，请进一步做出完整的链轮才好。新版的软件发生的齿形的顶部放大图如下：

可否在CAXA中绘制出链轮的最大和最小齿形图和计算值?如果能实现对指导生产是很有意义的.

几年前我也用QB做过类似的计算软件，后来找到现成的图库和专门软件，后者更方便了！
