Abstract
The utility model provides a sealing structure for a papermaking profiling roller head. The sealing structure for the papermaking profiling roller head can guarantee that a roller body an end cover are not worn excessively and respectively have a normal service life while effective sealing for lubricating oil in the roller body is achieved. The sealing structure of the papermaking profiling roller head comprises the roller body. The roller body is installed on a bearing pedestal through a bearing, end faces at the two ends of an outer ring of the bearing are respectively contacted with a sealing cover, the sealing cover is sleeved on the roller body and close to a power input side, an outlet of a lubricating oil passageway on the roller body is covered by the sealing cover, the other side of the sealing cover is a female labyrinth cover, the tooth-shaped end portion of the female labyrinth cover is mutually matched with the tooth-shaped end portion of a male labyrinth ring to form a labyrinth, the male labyrinth ring is sleeved on the roller body, and the junction surfaces of the roller body and the sealing cover are respectively convex-concave faces at the junction positions of the sealing cover and the roller body.
Description
Technical field
The utility model relates to papermaking profile shell roller head technical field, is specially the sealing configuration of papermaking profile shell roller head.
Background technique
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 papermaking 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 sealing configuration 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 support 3 by bearing 2, the end face at the two ends of described bearing 2 outer rings contacts with sealing cover 4 respectively, and described sealing cover 4 is set in described roll body 1, near the power input side, described sealing cover 4 covers the grease channel outlet 7 on the described roll body 1, the described sealing cover 4 of opposite side is female labyrinth lid 5, and the profile of tooth end of described female labyrinth lid 5 and the profile of tooth end of male labyrinth ring 6 complement each other to form the labyrinth, and described male labyrinth ring 6 is set in described roll body 1.The shortcoming of this sealing configuration is exactly: the friction between described sealing cover and the described roll body causes the wearing and tearing of sealing cover easily, thereby has influence on the integral sealing of roll body.
Summary of the invention
For the problems referred to above, the utility model provides the sealing configuration of papermaking profile shell roller head, when it can realize the lubricant oil effective sealing of roll body inside, guarantees that roll body and end cap can overweightly not wear and tear, and guarantee 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 support by bearing, the end face at the two ends of described bearing outer ring contacts with sealing cover respectively, described sealing cover is set in described roll body, near the power input side, described sealing cover covers the grease channel outlet on the described roll body, the described sealing cover of opposite side 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: the position that described sealing cover and described roll body combine, the junction plane of described roll body and described sealing cover is respectively male and female face.
It is further characterized in that: the male and female face of described roll body and the male and female face of described sealing cover are staggeredly arranged.
After the utility model adopts said structure, junction between roll body and the sealing cover, between be filled with extreme pressure lubricant, thereby so that end cap is in state of suspension, alleviate so largely the wearing and tearing between roll body and the end cap, guaranteed normal operation and the normal working life of roll body and sealing cover.
Description of drawings
Fig. 1 is the schematic representation of the sealing configuration of existing papermaking profile shell roller head;
Fig. 2 is structural representation of the present utility model.
Embodiment
Such as Fig. 1, shown in Figure 2, the utility model comprises roll body 1, roll body 1 is installed on bearing support 3 by bearing 2, the end face at the two ends of bearing 2 outer rings contacts with sealing cover 4 respectively, sealing cover 4 is set in roll body 1, near the power input side, sealing cover 4 covers the grease channel outlet 7 on the roll body 1, the sealing cover 4 of opposite side is female labyrinth lid 5, the profile of tooth end that 5 profile of tooth ends and male labyrinth ring 6 are covered in female labyrinth complements each other to form the labyrinth, male labyrinth ring 6 is set in roll body 1, the position that sealing cover 4 and roll body 1 combine, and the junction plane of roll body 1 and sealing cover 4 is respectively male and female face 8; The male and female face 8 of roll body 1 and the male and female face 8 of sealing cover 4 are staggeredly arranged.
Claims (2)
