As another kind of preferred version, plug medial surface described in the utility model is provided with groove, is provided with spheroid in groove, end in contact before spheroid outer end and mandrel.
As another kind of preferred version, spheroid described in the utility model is steel ball, and described bearing block adopts the steel bearing block.
As another kind of preferred version, bearing described in the utility model comprises two parts, is provided with spacer between two parts bearing.
As another kind of preferred version, core back-end described in the utility model diameter greater than the anterior diameter of mandrel, is ring-shaped depression between mandrel front portion and core back-end, and rear end, mandrel front portion is round table-like annular protrusion, and described sealing ring is placed in ring-shaped depression.
As another kind of preferred version, be provided with the bearing block positive stop lug boss corresponding to the bearing block rear end on core back-end described in the utility model circumference.
Secondly, be provided with corresponding to the bearing block rear end the dustproof outer shroud that forms the revolution gap structure with the bearing block rear end on core back-end described in the utility model circumference.
In addition, bearing block described in the utility model rear end is outer wall indent annulus joint, and dustproof outer shroud front end longitudinal section is the L shaped structure corresponding with indent annulus joint.
The utility model beneficial effect.
The utility model mandrel rear portion is provided with the sealing ring that prevents that the lubricating oil in bearing from overflowing.Sealing ring can effectively prevent the overflowing of lubricating oil in bearing, and sealing, oil-containing are effective, greatly reduces maintenance time and the cost of roller bearing.
In addition, the utility model is simple in structure, processing cost is low, is convenient to promote the use of.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model bearing block front-end architecture schematic diagram.
Fig. 3 is the utility model overall appearance figure.
In figure, 1 is that roller, 2 is plug for groove, 15 for spheroid, 14 for bearing block, 13 for spacer, 12 for bearing, 11 for mandrel, 10 for annular protrusion, 9 for O RunddichtringO, 8 for ring-shaped depression, 7 for indent annulus joint, 6 for positive stop lug boss, 5 for L shaped structure, 4 for dustproof outer shroud, 3.
The specific embodiment
As shown in the figure, the utility model comprises roller 1 and bearing block 12, and roller 1 two ends mandrel 9 is placed in the bearing 10 in bearing block 12, and mandrel 9 front ends are provided with plug 15, and mandrel 9 rear portions are provided with the sealing ring that prevents that the lubricating oil in bearing 10 from overflowing.
Described sealing ring is O RunddichtringO 7.
Described plug 15 is positioned in bearing block 12 by the back-up ring in its outside.
Described plug 15 medial surfaces are provided with groove 14, are provided with spheroid 13 in groove 14, spheroid 13 outer ends and the front end in contact of mandrel 9.Can effectively prevent the play of roller 1 position, left and right by spheroid 13, and spheroid 13 outer ends contact for point with mandrel 9 front ends, contact friction force is little.
Described spheroid 13 is steel ball, and described bearing block 12 adopts the steel bearing block.The steel bearing block can adopt tube material to make, and has solved the problems such as existing profiled piece processing difficulties.
Described bearing 10 comprises two parts, is provided with spacer 11 between two parts bearing 10.
