称重量

The YWD series oil-cooled motor-driven Rolling Drums equipped are newest drivers for belt conveyers, which reducing speed mechanism are equipped into the drum and driving motors are equipped out of the drum. So they are also called as reducing speed rolling drum or outboard motor rolling drum. The rolling drums have many advantages such as compact construction, light weight, small size, reliable performance, convenience of installation and maintenance, etc. It can be used as driving force for fixed belt conveyers of type of TD75 and DTⅡ, which transport all kinds of loose and lumpy materials, or other cargo.

YWD型油冷外装式电动滚筒是带式输送机的最新驱动装置，它是将减速机构装入滚筒它是将减速机构装入滚筒体内，亦称减速滚筒，减速滚筒再与电机外联构成驱动装置一外装式电动滚，具有结构紧凑、重量轻、体积小、性能可靠、安装及维护方便等优点，广泛应用于TD75、DTⅡ固定式带式输送机作为动力，运送各种散状、块状特料和其他货物。

To do this, it would be necessary only to make a little ball of earth that can be accurately weighed ; then we could easily calculate how many times the earth is larger than this little ball; and by so doing, we might tell, at one's fingerends, that if we suppose the little earth-ball to weigh a hundred-weight the whole globe, being so many times larger, must weigh so many hundred-weights.

要做到这一点，仅仅需要制作一个可以精确称出重量的小土球；然后我们可以很容易计算出地球比小土球大多少倍；如此做来，我们就可以掰着手指头说出，如果假定小土球重一百磅，那么地球大它多少倍，则必然重它多少倍。
