Abstract
The utility model provides a compression structure of a papermaking profiling roll head. The compression structure can effectively seal lubricating oil inside a roll body, is convenient to detach at the same time, and ensures normal service life of the roll body and an end cover. The compression structure comprises a roll body which is arranged on a bearing seat through a bearing. Faces of two ends of an outer ring of the bearing respectively contact with sealing covers which are sleeved on the roll body. The sealing covers are female labyrinth covers. Tooth-shaped end portions of the female labyrinth covers and tooth-shaped end portions of a male labyrinth ring are mutually matched to form a labyrinth. The male labyrinth ring is sleeved on the roll body. A circular ring groove is arranged on the roll body. A bone sealing ring is arranged in the circular ring groove.
Description
Technical field
The utility model relates to papermaking profile shell roller head technical field, is specially the compressing structure of papermaking profile shell roller head.
Background technology
In the papermaking operation, squeezing is exactly that l Water Paper is guided to one with between two shaping rods of felt, the extrusion of mat shaping rod and the water sorption of felt, l Water Paper is done further dehydration, and make papery tightr, to improve paper, gain in strength, and the water that felt is inhaled enters in the roller by the paper grade (stock) profile shell and discharges from outlet conduit.Roll body Surface Contact paper, the roll body surface has or not greasy dirt, directly have influence on the yield rate of paper, the compressing structure of existing papermaking profile shell roller head, its structure is seen Fig. 1, it comprises roll body 1, described roll body 1 is installed on bearing block 3 by bearing 2, the end face at the two ends of described bearing 2 outer rings contacts with seal cover 4 respectively, described seal cover 4 is set in described roll body 1, described seal cover 4 is female labyrinth lid, and the profile of tooth end of described female labyrinth lid and the profile of tooth end of male labyrinth ring 5 complement each other to form the labyrinth, and described male labyrinth ring 5 is set in described roll body 1.The shortcoming of this structure is exactly: the lubricating oil infiltration is lubricated, and is loosening easily between described seal cover and the described roll body, thereby has influence on the normal operation of roll body; And the shortcoming of bringing in order to solve said structure, usually design in the industry now at roll body 1 axle head interference fit suit axle sleeve 8, by screw 9 location, as shown in Figure 2, but because this structure of interference fit that adopts, dismounting is difficulty relatively, need to beat, can change and keep in repair, very inconvenient.
Summary of the invention
For the problems referred to above, the utility model provides the compressing structure of papermaking profile shell roller head, when it can realize the lubricating oil effective sealing of roll body inside, dismantles also more conveniently, guarantees the normal service life of roll body and end cap.
The utility model is realized by following proposal: it comprises roll body, described roll body is installed on bearing block by bearing, the end face at the two ends of described bearing outer ring contacts with seal cover respectively, described seal cover is set in described roll body, described seal cover is female labyrinth lid, the profile of tooth end of described female labyrinth lid and the profile of tooth end of male labyrinth ring complement each other to form the labyrinth, described male labyrinth ring is set in described roll body, it is characterized in that: on the described roll body annular groove is set, the bone sealing ring is set in the described annular groove.
The beneficial effects of the utility model are, be provided with annular groove at roll body, the bone sealing ring is set in the annular groove, it not only can effective location to the male labyrinth ring in the outside, and also can effectively limit oil exosmoses, reach good sealing effectiveness, simultaneously dismounting is also more convenient, has guaranteed the normal operation of equipment.
