Abstract
The utility model relates to a bearing sealing device for a grinding roll of a vertical mill, which belongs to the cement raw material production equipment. The bearing sealing device comprises a bearing cap, a J-shaped sealing device and a pressure plate, and the structure thereof is characterized in that a packing piece is arranged between the pressure plate and a shaft, the packing piece enwinds the shaft and is matched with the pressure plate, a cover board is connected with the pressure plate, and the cover board is pressed on the packing piece. The cover board and the pressure plate together achieve the fixture function to the packing piece, whereas the packing piece achieves the sealing function. The utility model has the advantages of reasonable structural design, effective oil leak prevention, and sealing performance improvement.
Description
Technical field
The utility model relates to a kind of vertical mill roller bearing sealing device, belongs to the cement slurry production equipment.
Background technology
The vertical grinder of domestic production at present, HG4-338-66 " sealing of J type " (material is a butyl rubber) pairing two way seal is adopted in the sealing of grinding roller bearing, but actual this sealing structure poor effect of in the equipment use, finding, the leakage of oil problem is more serious, has influenced the normal operation of equipment and the product quality of raw material to a certain extent.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of reasonable in design, can effectively prevent oil leakage phenomenon, improves the vertical mill roller bearing sealing device of sealing property.
It is this vertical mill roller bearing sealing device that the utility model solves the problems of the technologies described above the technical scheme that is adopted, comprise bearing cap, J type sealing device and pressing plate, its design feature is: be provided with packing between described pressing plate and the axle, packing is wrapped on the axle, packing and pressing plate are complementary, also be provided with the cover plate that links to each other with pressing plate, cover plate is pressed on the packing.Cover plate and pressing plate play fixing effect to packing jointly, and packing plays the effect of sealing.
Pressing plate described in the utility model links to each other by follower bolt with bearing cap, and cover plate links to each other by cover plate bolt with pressing plate.
Packing described in the utility model is that the size and the specification of the diameter of axle is 12 * 12 oil immersion asbestos packings.
Packing described in the utility model encloses half around three on axle.Like this be best mode around mode, can effectively play the effect of sealing, convenient again fixing.
The utility model is compared with prior art and is had the following advantages and effect: compare with domestic like product, the vertical grinder grinding roller associated sealing arrangement for bearings that this is novel, in the raising of sealing property, played very big effect, make no longer outwards seepage of grinding roller inner chamber lubricating oil, guaranteed the normal operation of equipment and the product quality of raw material.Owing to, make that fixing of packing is more firm in the mode that has adopted bolting.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place among Fig. 1.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, 2, present embodiment is made up of bearing cap 2, J type sealing device 3, packing 5, cover plate 7 and pressing plate 6, bearing cap 2 and mill 1 supporting linking to each other of body, J type sealing device 3 is installed between axle 4 and the bearing cap 2, pressing plate 6 is pressed on J type sealing device 3 and the bearing cap 2, fixedly the position of J type sealing device 3.Packing 5 is arranged between pressing plate 6 and the axle 4, and packing 5 is provided with cover plate 7.Packing 5 is to adopt the oil immersion asbestos plate of specification 12 * 12 to twine three circles half on axle 4, fixes with follower bolt 8 and cover plate bolt 9 then, forms sealing.Follower bolt 8 nails are between pressing plate 6 and bearing cap 2, and cover plate bolt 9 nails are between cover plate 7 and pressing plate 6.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
