The radius of described dust ring madial wall is less than the radius of dust ring place rotating shaft, and two dust rings and rotating shaft are interference fit.
On the ear end face of described dust ring, form semicircle annular boss, semicircle annular boss sleeve is in the annular groove of bearing end cover.
In described bearing end cover, be equipped with seal ring, seal ring sleeve is in rotating shaft.
In rotating shaft between described dust ring and baffle plate, form the axle collar, the front end of rotating shaft axle journal forms the shaft shoulder, and the distance between the shaft shoulder and bearing shell is less than the distance of dust ring ear end face to bearing end cover front-end face.
The lower end of described spacer forms the weep hole that runs through spacer sidewall.
The beneficial effects of the utility model are:
It is simple and compact for structure, be provided with the multilayer proofing structures such as baffle plate, dust ring, seal ring, thereby rainwater, the dust etc. that can effectively prevent bearing outside enter sliding bearing inside, make the good oil film of the inner formation of sliding bearing, the working life of having improved sliding bearing.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram at A place in Fig. 1 of the present utility model;
Fig. 3 is the structural representation of dust ring of the present utility model.
In figure: 1, bearing support; 2, bearing end cover; 3, spacer; 4, king-bolt; 5, baffle plate; 6, dust ring; 7, seal ring; 8, bearing shell; 9, rotating shaft; 10, stove bolt; 2a, annular groove; 3a, weep hole; 5a, rotating shaft via hole; 5b, V-type groove; 6a, semicircle annular boss; 9a, the axle collar; 9b, the shaft shoulder; A, water (flow) direction.
Embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of sliding bearing Novel protective structure, comprise bearing support 1, the rear end of bearing support 1 is provided with bearing shell 8, front-end face is provided with bearing end cover 2, on the front-end face of bearing end cover 2, form annular groove 2a, 6, two dust rings 6 of dust ring that are inserted with two semicircle annulars in annular groove 2a are fixed together also holding in rotating shaft 9 by stove bolt 10; The front side of described bearing end cover 2 is provided with spacer 3 and baffle plate 5 successively, and king-bolt 4 is spirally connected and is fastened on bearing end cover 2 through spacer 3 and baffle plate 5, and the center of described baffle plate 5 forms rotating shaft via hole 5a, forms annular V-type groove 5b on the sidewall of rotating shaft via hole 5a.
Described baffle plate 5 adopts the aluminium sheet of 3～5mm, and the diameter of the rotating shaft via hole 5a of baffle plate 5 is greater than the diameter of rotating shaft via hole 5a place's rotating shaft 1, and the diameter of rotating shaft via hole 5a is than the large 1～2mm of the diameter of rotating shaft 1, and rotating shaft 9 is Spielpassung with baffle plate 5.
