Sealing structure, provided with veneer gluing layer, of stirring barrel bearing

Abstract

The invention relates to a sealing structure, provided with a veneer gluing layer, of a stirring barrel bearing. The sealing structure, provided with the veneer gluing layer, of the stirring barrel bearing is characterized by comprising an end cover, a sealing cover and a dual-layer framework oil seal; the end cover is installed on the outer end side of the bearing; a sealing groove is formed in the middle position of the end face, away from the bearing end, of the end cover; the double-layer framework oil seal is installed in the sealing groove; the sealing cover is installed on the end face,away from the bearing end, of the end cover; the PVC veneer gluing layer is arranged on the end face, away from the bearing end, of the sealing cover, and the thickness of the veneer gluing layer is2 mm. According to the sealing structure, provided with the veneer gluing layer, of the stirring barrel bearing, due to the fact that the dual-layer framework oil seal is installed in the sealing groove, it is effectively prevented that slurry enters the bearing, the service life of the bearing can be prolonged easily, and the shutdown overhauling frequency is reduced. According to the sealing structure, the framework oil seal can be replaced just by disassembling and assembling the sealing cover, and overhauling is convenient.

Description

technical field [0001] The invention relates to the technical field of mixing buckets, in particular to a sealing structure of a mixing bucket bearing with a skin layer. Background technique [0002] The mixing tank needs to work continuously for a period of time to mix the slurry in the tank evenly. The lower bearing of the mixing bucket bearing seat is near the slurry and needs to be sealed to prevent the slurry from entering the bearing, so as to prevent the bearing from being worn out and shutting down for maintenance. At present, the lower bearing of the mixing bucket bearing seat is equipped with a gland with a trapezoidal groove, and the cow felt is inserted into the trapezoidal groove for sealing, so it is difficult to replace the cow felt. The slurry enters the bearing, aggravating the wear of the bearing, resulting in frequent shutdown for maintenance. Contents of the invention [0003] The purpose of the present invention is to provide a sealing structure with...
