對于大型軋機(jī)來說，尤其是熱軋機(jī)必須用動力傳動輥道。多的還是集體傳動式，特別是長度不大而軋件斷面很大時，適宜用集體傳動。單獨(dú)傳動輥道通常用于長距離的軋件的傳送。

For large rolling mills, in particular, the hot rolling mill must be powered by a power drive roller. The most important is the collective transmission type, especially when the length is small and the section of the workpiece is very large, it is suitable for the use of collective transmission. The single drive roller is usually used for the transmission of long distance parts.

新式的高速熱軋機(jī)及連續(xù)式熱軋機(jī)一般都采用單獨(dú)傳動系統(tǒng)。包膠滾筒安裝方便包膠滾筒安裝起來特別的方便，不需要安裝好在送過去，現(xiàn)場進(jìn)行安裝就可以了，滾筒也是不需要拆卸的，這樣是非常方便的，你只需要付錢、收獲、等著用就可以了，其他的都有專業(yè)的人士來干。單獨(dú)傳動優(yōu)點(diǎn)很多，它的制作簡單，由于不需要傳動齒輪及傳動軸，從而大大簡化了輥道的機(jī)械結(jié)構(gòu)，使裝拆、檢修和潤滑等問題也都大大簡化了，而且對輥?zhàn)酉嗷ノ恢弥疁?zhǔn)確度的要求也沒有集體傳動時那樣嚴(yán)格。

The new type of high speed hot rolling mill and continuous hot rolling mill generally use a separate transmission system. Individual drive has many advantages, making it simple, because it does not need the transmission gear and the transmission shaft, which greatly simplifies the mechanical structure of the roller, the assembly and disassembly, maintenance and lubrication problems are greatly simplified, and the accuracy of the location of each roller requirements are not as strict collective transmission.

皮帶輸送機(jī)的結(jié)構(gòu)參數(shù)的優(yōu)化方法皮帶輸送機(jī)的結(jié)構(gòu)雖然受到了種種工況的限制，而輸送機(jī)的工作狀態(tài)是處于滿載正常運(yùn)行的狀態(tài)，在常規(guī)設(shè)計計算方法完成后，可以進(jìn)行采用離散變量優(yōu)化的網(wǎng)絡(luò)法，對帶式輸送機(jī)參數(shù)進(jìn)行優(yōu)化設(shè)計 。

Optimization of the structural parameters of belt conveyer, the structure of belt conveyer is restricted by various working conditi, and the working state of the conveyor is in a state of full load. After the completion of the conventional design calculation method, the network method of discrete variable optimization can be used to optimize the parameters of the belt conveyor. Chemical design.
