Abstract
The invention provides a sealing structure for a roller head of a papermaking compression roller, which can be used for enabling the roller body and an end cover not to be severely worn, as well as ensuring the normal service lives of the roller body and the end cover while realizing the effective sealing of lubricating oil inside the roller body. The sealing structure comprises a roller body, wherein the roller body is arranged on a bearing base by a bearing; the end surfaces at two ends of the bearing outer ring respectively contact a sealing cover; the sealing cover is sleeved on the roller body, and close to the power input side; the sealing cover covers an outlet of a lubricating oil passage on the roller body; the sealing cover at the other side is a female maze cover; a tooth-shaped end part of the female maze cover and a tooth-shaped end part of a male maze ring are matched with each other to form a maze; the male maze ring is sleeved on the roller body; and at the position the sealing cover is combined with the roller body, a combination surface of the roller body and the sealing cover is a male and female face.
Description
Technical field
The present invention relates to papermaking profile shell roller head technical field, be specially a kind of 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 invention provides a kind of sealing configuration of papermaking profile shell roller head, when it can realize the lubricant oil effective sealing of roll body inside, guarantee 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 present invention realizes 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 present invention 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 invention.
Embodiment
As shown in Figure 1 and Figure 2, the present invention includes 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)
