Abstract
The utility model discloses a bearing protective device, especially discloses a vertical rolling mill roller lower bearing protective device belonging to the metallurgy production equipment technology field. The vertical rolling mill roller lower bearing protective device can be used to prevent water, slag from entering the inside of the bearing, and to prolong the service lifetime. The protective device comprises a vertically-arranged roller, a bearing used for supporting the roller, and a lower bearing seat used for installing the bearing. A spacing ring is disposed between a roller end part and the bearing seat along the axial direction. A protective sleeve is also provided, and is sleeved on the spacing ring tightly. The protective sleeve can form a trumpet shape having a large lower part and a small upper part under the extrusion action of the roller end part and the bearing seat, and can be used to cover a bearing end surface.
Description
Technical field
The utility model relates to a kind of bearing protection device, especially relates to a kind of vertical mill roll lower bearing protective device, belongs to the metallurgical production equipment technical field.
Background technology
In bar production enterprise, the configuration of its production technology be that the milling train horizontally and vertically alternative is arranged, when milling train turn over become vertical mill after turning 90 degrees after; Cooling water and the rolling middle tiny iron scale that produces can directly be flushed on the roll lower shaft bearing, will make roll bearing slag input, water inlet, long-play like this; Lubricating oil is just replaced by tiny iron scale in the bearing; Thereby the burn bearing accident takes place, damage equipment, influence is produced.
The utility model content
The utility model technical problem to be solved is: provide a kind of water, slag can avoided to get into bearing inside, prolong the bearing vertical mill roll lower bearing protective device in service life.
The technical scheme that adopts for solving the problems of the technologies described above is: a kind of vertical mill roll lower bearing protective device; Comprise the roll of vertical layout, the bearing of back-up roll and the lower shaft bearing that said bearing is installed; Between roll end and bearing block, be provided with space collar vertically; Also comprise protective sleeve, protective sleeve is socketed on the space collar closely, and is being the horn-like of cover cap bearing face little down big under the extruding of roll end and bearing block.
Further be that protective sleeve is processed by polytetrafluoroethylmaterial material.
Further be, protective sleeve is cylinder-like structure, and its two ends have the outside boss that thickens.
Further be that the axial length of protective sleeve is than the big at least 4mm of axial length of space collar.
Further be that the interior table place at protective sleeve two ends has the assembling chamfering.
The beneficial effect of the utility model is: through protective sleeve of socket on the space collar between roll end and the lower shaft bearing; And make this protective sleeve be the horn-like of cover cap bearing face little down big under the extruding of roll end and lower shaft bearing; Like this; Be in operation, just flow away, no longer get in the bearing of milling train bottom from horn-like protective jacket outside from top cooling water and the dregs that flow down along roll; Thereby bearing has been played good protective action, and then prolonged the service life of bearing.
Description of drawings
Fig. 1 is the structural representation of a kind of vertical mill roll of the utility model lower bearing protective device;
The front view of the protective sleeve that Fig. 2 relates to for the utility model;
Fig. 3 is the vertical view of Fig. 2.
Be labeled as among the figure: roll end 1, bearing 2, lower shaft bearing 3, space collar 4, protective sleeve 5, boss 51.
The specific embodiment
Get into bearing inside like Fig. 1, Fig. 2 and a kind of water, the slag can avoided that is the utility model provides shown in Figure 3, prolong the bearing vertical mill roll lower bearing protective device in service life.Said bearing protection device comprises the roll of vertical layout, the bearing 2 of back-up roll and the lower shaft bearing 3 that said bearing 2 is installed; Between roll end 1 and bearing block 3, be provided with space collar 4 vertically; Also comprise protective sleeve 5; Protective sleeve 5 is socketed on the space collar 4 closely, and is being the horn-like of cover cap bearing face little big down under the extruding of roll end 1 and bearing block 3.Like this; Through protective sleeve 5 of socket on the space collar 4 between roll end 1 and the lower shaft bearing 3, and make this protective sleeve 5 be the horn-like of cover cap bearing face little big down under the extruding of roll end 1 and lower shaft bearing 3, like this; Be in operation; Just flow away from horn-like protective jacket 5 outsides from top cooling water and the dregs that flow down along roll, no longer get in the bearing 2 of milling train bottom, thereby bearing 2 has been played good protective action; And then having prolonged service life of bearing 2, the arrow among the figure is represented the flow direction of cooling water and dregs.
In order to improve the anti-wear performance of protective sleeve 5; Can make protective sleeve 5 under the extruding of roll end 1 and lower shaft bearing 3, be easy to produce distortion again; So that the cover cap bearing face, can prolong 5 service lifes of protective sleeve simultaneously again, protective sleeve 5 is processed by polytetrafluoroethylmaterial material; Its structure is cylindric, has the outside boss 51 that thickens at the two ends of cylindric protective sleeve 5.Like this,, just can make protective sleeve 5 under the extruding of roll end 1 and lower shaft bearing 3, produce distortion easily because polytetrafluoroethylmaterial material matter is soft wear-resisting, and wear-resisting.And setting thickens the service life that boss 51 can prolong protective sleeve 5 at protective sleeve 5 two ends.Further; End face for the better cover cap bearing of the deformation energy of protective sleeve 5 after extruding; The axial length of protective sleeve 5 is than the big at least 4mm of axial length of space collar 4, and protective sleeve 5 just can all cover the end face of bearing after being extruded distortion like this, improves the protection effect.Because protective sleeve 5 is to be socketed in closely on the space collar 4, to install for ease, the interior table place at protective sleeve 5 two ends has the assembling chamfering.
