Ф2600筒辊磨滑履支承及密封装置设计资料本课题主要设计的是用于水泥粉磨或矿渣粉磨的筒辊磨在高速转动下筒体密封和支承的问题。筒辊磨的转速要高于临界转速的1.2倍，在如此高速转动的情况下要保证筒体的密封是-个严峻的问题，筒辊磨端部密封采用橡胶圈的密封，筒辊磨属封闭式粉磨系统，要求有严格的封闭性，采用橡胶圈的密封能有效的防止粉磨过程中粉尘的外泄，保证筒体的密封性；筒辊磨的支承装置要承受回转部分和物料在运动过程或静止过程状态时的载荷；筒辊磨的支承装置的工作特点：-是承受的载荷重，并且具有-定的振动；二是筒辊磨的工作环境恶劣，灰尘大；因此设计支承装置时，不但要考虑到筒辊磨能够连续运转，还要防止灰尘进入其中。
因此在支承装置上采用滑履支承，滑履支承可以很好的承受筒体的载荷重量，保证筒体在转动时的平稳性，有利于提高产品的质量。密封橡胶圈的采用使得密封效果比以前的迷宫密封有着更好的稳定性。

The design of φ2，600 roller grinding machines support and seal
Abstract: This article is mainly designed for the mill roll of grinding or slag cement grinding. The roller machines rotational speed should be 1.2 times higher than the critical rotation speed. It is a stern question to make sure the roller bodys seal in such high speed. The roller grinding machine which belongs to closed powder system required by strict blockage. And the machines 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 machines 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
