支架多用型鋼制成，有焊接和螺栓連接兩種結(jié)構(gòu)。為了通用和便于制造，已把上述三種常用輥?zhàn)拥闹Ъ茏鞒删哂袠?biāo)準(zhǔn)長度的通用構(gòu)件，在設(shè)計(jì)時(shí)可直接選用。

The  is made of  steel with two structures: welding and bolt connection. For the  of generaland convenient manufacturing, the above three common roller  have been used as a common component with a standard length, which can be used directly in the design.

對于大型軋機(jī)來說，尤其是熱軋機(jī)必須用動(dòng)力傳動(dòng)輥道。多的還是集體傳動(dòng)式，特別是長度不大而軋件斷面很大時(shí)，適宜用集體傳動(dòng)。單獨(dú)傳動(dòng)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(dòng)系統(tǒng)。單獨(dú)傳動(dòng)優(yōu)點(diǎn)很多，它的制作簡單，由于不需要傳動(dòng)齒輪及傳動(dòng)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(dòng)時(shí)那樣嚴(yán)格。這是為了在軋制薄規(guī)格的帶鋼時(shí)避免使帶鋼在輥道上因終軋速度高而造成折疊。

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.
