- Ф2600筒輥磨滑履支承及密封裝置設(shè)計(jì)資料本課題主要設(shè)計(jì)的是用于水泥粉磨或礦渣粉磨的筒輥磨在高速轉(zhuǎn)動下筒體密封和支承的問題。筒輥磨的轉(zhuǎn)速要高于臨界轉(zhuǎn)速的1.2倍，在如此高速轉(zhuǎn)動的情況下要保證筒體的密封是一個嚴(yán)峻的問題，筒輥磨端部密封采用橡膠圈的密封，筒輥磨屬封閉式粉磨系統(tǒng)，要求有嚴(yán)格的封閉性，采用橡膠圈的密封能有效的防止粉磨過程中粉塵的外泄，保證筒體的密封性；筒輥磨的支承裝置要承受回轉(zhuǎn)部分和物料在運(yùn)動過程或靜止過程狀態(tài)時的載荷；筒輥磨的支承裝置的工作特點(diǎn)：一是承受的載荷重，并且具有一定的振動；二是筒輥磨的工作環(huán)境惡劣，灰塵大；因此設(shè)計(jì)支承裝置時，不但要考慮到筒輥磨能夠連續(xù)運(yùn)轉(zhuǎn)，還要防止灰塵進(jìn)入其中。
因此在支承裝置上采用滑履支承，滑履支承可以很好的承受筒體的載荷重量，保證筒體在轉(zhuǎn)動時的平穩(wěn)性，有利于提高產(chǎn)品的質(zhì)量。密封橡膠圈的采用使得密封效果比以前的迷宮密封有著更好的穩(wěn)定性。

The design of φ2,600 roller grinding machine’s support and seal
Abstract: This article is mainly designed for the mill roll of grinding or slag cement grinding. The roller machine’s rotational speed should be 1.2 times higher than the critical rotation speed. It is a stern question to make sure the roller body’s seal in such high speed. The roller grinding machine which belongs to closed powder system required by strict blockage. And the machine’s nose seal uses the labyrinth seal which can be able to effectively prevent the dust released outside in the process of powder rubs, and to achieve the seal of roller. The roller grinding machine’s support system needs to withstand the load that the rotation part and the material engender in the rate process or the static process. The characteristic of supporting system is as below:
withstand the heavy load and a certain vibration;
the bad working conditions with heavy dust.
Thus, when designing the support system, we need to consider not only that the roller grinding machine can continuous working, but also preventing dust enters.
Now, we introduce the crawler shoe support into the support system, as this support can withstand the heavy load weight of the roller body very well, and assure the stability when the roller body is rotating, and moreover, is very fit for improving the quality of the product. The adoption of the labyrinth seal...
