在图示轮系中,根据齿轮1 的转动方向,蜗轮4 的转动方向为逆时针。http://image.zhihuishu.com/testzhs/onlineexam/ueditor/201702/280b268c577841dc806f6b55ccaf3c7f.png
举一反三
- 在图示轮系中,根据齿轮1的转动方向,蜗轮4的转动方向为逆时针。
- 下面是轴测图的是( )。 A: <img src="http://image.zhihuishu.com/testzhs/onlineexam/ueditor/201702/748c4269a50a4aa2bfab8b91fd4f0a48.png" /> B: <img src="http://image.zhihuishu.com/testzhs/onlineexam/ueditor/201702/fd1616f4949a4f5dbe2d263f38f5bbf6.png" /> C: <img src="http://image.zhihuishu.com/testzhs/onlineexam/ueditor/201702/d6dae74b734542a99835980a703c3222.png" /> D: <img src="http://image.zhihuishu.com/testzhs/onlineexam/ueditor/201702/9c9af01bbf134f52be1439f428bb093a.png" />
- 图示轮系,给定齿轮 1 的转动方向如图所示,则齿轮 3 的转动方向 。http://p.ananas.haust.edu.cn/star3/origin/838fa838c8d567444e3ce62d27c5934c.png
