Abstract
The utility model relates to a scraping board type coal burning boiler slag extractor, in particular to a bearing seal device of the scraping board type coal burning boiler slag extractor. The bearing seal device of the scraping board type coal burning boiler slag extractor mainly solves the technical problems in the prior art that in the using processes of an existing scraping board type coal burning boiler slag extractor, coal cinder granules easily enter into a bearing, movement of the bearing is influenced, damage of the bearing is caused, service life of the bearing of the scraping board type coal burning boiler slag extractor is reduced, and the like. The bearing seal device of the scraping board type coal burning boiler slag extractor comprises a revolving shaft (1), and is characterized in that a bearing seat (2) is arranged at one end of the revolving shaft (1), a framework seal groove (3) is formed in the bearing seat (2), a framework seal (4) is installed in the framework seal groove (3) in an embedded mode, a bearing (5) is installed in the bearing seat (2), and a bearing pressing cover (6) is arranged at the outer end of the bearing seat (2).
Description
Technical field
The utility model relates to a kind of scraper-type coal burning boiler slagging machine, especially relates to a kind of scraper-type coal burning boiler slagging machine associated sealing arrangement for bearings.
Background technique
Not to be with sealing on present SGC type scraper-type coal burning boiler slagging machine upper bearing bracket.As shown in Figure 1, in use the cinder granule is easy to run in bearing and goes, and affects the operation of bearing, causes damage of bearings, reduces the working life of SGC type scraper-type coal burning boiler slagging machine upper bearing (metal).
The model utility content
The utility model is to provide a kind of scraper-type coal burning boiler slagging machine associated sealing arrangement for bearings, its be mainly solve the existing scraper-type coal burning boiler of prior art slagging machine in use the cinder granule be easy to run in bearing and go, affect the operation of bearing, cause damage of bearings, the technical problem in the working life of reduction scraper-type coal burning boiler slagging machine upper bearing (metal) etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Scraper-type coal burning boiler slagging machine associated sealing arrangement for bearings of the present utility model comprises rotating shaft, and described rotating shaft one end is provided with bearing support, have the reinforced seal groove on bearing support, be embedded with reinforced seal in the reinforced seal groove, bearing is housed in bearing support, the outer end of bearing support is provided with bearing gland.Reinforced seal groove of processing on the basis of original bearing support is installed a reinforced seal on groove.Can prevent effectively that like this cinder granule from entering into bearing along axle.In reinforced seal, multiple sealing lips can be set, can prevent further that like this cinder granule from entering in bearing.
As preferably, but described bearing gland is provided with the boss of positioning bearing.Boss inwardly arranges, and can withstand bearing.
Therefore, the utility model just can be realized owing to needing only in reinforced seal of bearing support increase, so installation is dangerous convenient.Can prevent that effectively the cinder granule from going inside entering into bearing, the working life of effectively having protected bearing to improve bearing, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of former scraper-type coal burning boiler slagging machine bearing;
Accompanying drawing 2 is a kind of structural representations of the present utility model.
Component, position and numbering in figure: rotating shaft 1, bearing support 2, reinforced seal groove 3, reinforced seal 4, bearing 5, bearing gland 6, boss 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the scraper-type coal burning boiler slagging machine associated sealing arrangement for bearings that this is routine as Fig. 2, comprises rotating shaft 1, rotating shaft one end is provided with bearing support 2, has reinforced seal groove 3 on bearing support, is embedded with reinforced seal 4 in the reinforced seal groove, bearing 5 is housed in bearing support, and the outer end of bearing support is provided with bearing gland 6.But bearing gland is provided with the boss 7 of positioning bearing 5.
During use, rotating shaft place that whole associated sealing arrangement for bearings is encased in scraper-type coal burning boiler slagging machine gets final product.
The above is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
