Described bearing support upper box and bearing support lower box inwall offer the annular groove for clamping bearing box fixed dam.
Described bearing box opening end is by means of socket head screw fixed installation bearing support transparent cover, described roller axle end arranges through the through hole in the middle part of bearing support transparent cover and arranges outside framework oil seal roller journal and lid through hole, and described bearing support transparent cover is also provided with for the oil hole to bearing charging-up lubricant oil.
Bearing box sideboard is installed by means of bolt in one end that described roller axle is positioned at bearing box.
The beneficial effect adopting technique scheme to produce is: by having assembled under bearing support and roller line, integral replacing is reached the standard grade, bearing support intake tunnel end is connected to clean circulating water pipeline by flexible pipe, open pipe valve, water forms a waterwall between bearing support bonnet and bearing box fixed dam, effectively stops the heat radiation of fire door; Simultaneously by the flowing of water, constantly take away the heat on bearing support, ensure that internal bearings is run under the environment of a lower temperature, utilize outside framework oil seal to be well sealed in bearing box by grease, improve bearing lubrication effect and working life; Utilize the clean circulating water of exhalant canal directly to wash away roll neck cooling, avoid iron scale deposition, ensure that oil product cleans, improve the working life of outside framework oil seal.
