Abstract
The utility model relates to a slipper cover sealing structure of a large scale slipper pipe mill, which is characterized in that the outer side of a slipper cover (1) is equipped with a whole circle of sealing rings (4) with Y-shaped cross section, the inner side of the slipper cover (1) is equipped with a whole circle of oil retaining rings (3). The slipper cover sealing structure has the advantages that the sealing structure is simple in structure, the sealing rings are convenient in regulation and installation, the leakage rate of lubricating oil is significantly reduced, service life of the sealing rings is prolonged and the economic value of application is high.
Description
Technical field
The utility model relates to a kind of crawler shoe cover hermetically-sealed construction of large-scaled slide shoe tube mill.
Background technology
At present, maximize as the tube mill deisgn approach of cement plant main process equipment, the base bearing that the both ends or one end of grinding machine need not be common supports, but adopts slide shoe bearing to support, and because of its many superiority, is accepted by increasing user.The crawler shoe case is as the vitals of slide shoe bearing, it is formed closing by flange by the burst case, the bottom is fixed on (see figure 1) on the slide shoe bearing base plate, in order to prevent that dust from entering in the slide shoe bearing and oil leak, cylindrical shell slip ring 2 both sides at crawler shoe case 1 are provided with a seal structures, and common hermetically-sealed construction has: the rubber lip-type seal (being similar to the lip-type seal circle) of the sealing of General Purpose Rubber circle, band spring.
For General Purpose Rubber circle sealing (see figure 4), because rubber seal 9 its cross sections are abundant, elasticity is relatively poor, and sealing lip is very little, and the internal grease storage capacity is few.After the installation, the stability on sealing surface is not enough, and its labial surface and sealing surface are difficult to fit good, gauffer occurs and cause leakage of oil.
For the rubber lip-type seal (see figure 5) of band spring, lip-type seal circle 10 is very big because of the diameter of its sealing surface, needs very big spring tightening force could produce required sealing radial load, so just requires the spring that adopts rigidity big.The spring rigidity is big, and difficulty was bigger when the scene stretched it, is difficult for installing.Secondly the tightening force of spring is wayward, because the radial load that is obtained can not be excessive, otherwise very quick-wearing heating of lip, influences the life-span of lip packing; Too small its labial surface of radial load and sealing surface are fitted also bad, cause leakage of oil.
Because there is above-mentioned defective in the hermetically-sealed construction that existing crawler shoe cover is adopted, thereby general leakage of oil is serious, and workshop condition has increased maintenance workload again when being polluted, also caused the waste of resource.
Summary of the invention
The technical problems to be solved in the utility model is exactly the serious problem of general leakage of oil at existing tube mill crawler shoe cover hermetically-sealed construction place.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Arranged outside one whole ring cross-section at the crawler shoe case is lambdoid sealing ring, and the inboard of crawler shoe case is provided with a whole circle oil scraper ring.
Aforementioned sealing ring (4) by being located at its outside trim ring (7) and along its circumference setting of trim ring (7) a plurality of compress, adjusting part, be fixed on the crawler shoe case (1).
Compared with prior art, the utlity model has with advantage and characteristics:
1) is provided with oil scraper ring one in the chev(e)ron seal circle inboard of crawler shoe case, blocked the trend that lubricating oil outwards flows, therefore the sealing effectiveness at chev(e)ron seal circle place is increased greatly.
2) chev(e)ron seal circle setting height(from bottom) by compress, adjusting part circumferentially locatees, avoided making the position error that causes has been installed, and can regulate its setting height(from bottom) behind the ring wear, thereby remain the suitable sealing radial load of sealing surface, obviously reduce the leakage of lubricating oil, improved the service life of sealing ring.
Description of drawings
Fig. 1 is a slide shoe bearing overall structure cutaway view of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B enlarged drawing of Fig. 2.
Fig. 4 is existing General Purpose Rubber circle hermetically-sealed construction.
Fig. 5 is the rubber lip type hermetically-sealed construction of existing band spring.
The specific embodiment
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 to Fig. 3, consider that cylindrical shell slip ring 2 external diameter linear velocities are higher, the utility model in the arranged outside of crawler shoe case 1 a whole ring cross-section be lambdoid sealing ring 4, the inboard of crawler shoe case 1 is provided with a whole circle oil scraper ring 3 simultaneously.Sharp 3 of oil scraper rings of circle are welded on the slip ring boss 13, and this part has blocked the trend that most of lubricating oil flows to sealing ring 4.Sealing ring 4 by the trim ring 7 that is located at its outside and along trim ring 7 circumference uniform distributions more than one compress, adjusting part, be fixed on the crawler shoe case 1.Aforementioned trim ring 7 adopts channel-section steel to make, aforementionedly compress, adjusting part constitutes by adjusting bolt 5, fastening screw nut 6, pressing plate 8, support 11, sleeve 14, support 11 ringwise, be welded on the crawler shoe case 1, sleeve has a plurality of, evenly is welded on the support 11, and an end of regulating bolt 5 passes sleeve and support 11 and offsets with sealing ring 4, fastening screw nut 6 is positioned at the sleeve top, is used to adjust the length that adjusting bolt 5 stretches out support 11; Pressing plate 8 is L-shaped, is installed on the support 11 by bolt, and the one end withstands trim ring 7.By to regulating the adjustment of bolt 5, can circumferentially locate the theoretical setting height(from bottom) of sealing ring, and, equate with the radial spacing of cylindrical shell slip ring 2 sealing surfaces to guarantee crawler shoe case 1 with nut 6 lockings.
Regulate bolt 5 for the ease of operation, between sealing ring 4 and crawler shoe case 1, also be provided with annular liner plate 12, so just make wholely compress, separated by a distance between adjusting part and the crawler shoe case 1.
