Abstract
The utility model provides an oil discharging structure of a roller head of a papermaking profiling roller. The oil discharging structure of the roller head of a papermaking profiling roller can guarantee pollution-free production of paper, conveniently, rapidly discharge press oil, effectively seal up lubricating oil in a roller body and ensure that the roller body and an end cap cannot be abraded excessively. The oil discharging structure of the roller head of the papermaking profiling roller comprises the roller body, wherein the roller body is installed on a bearing seat through a bearing, end faces of two ends of an outer circle of the bearing respectively contact sealing caps, the sealing caps are sleeved on the roller body, the sealing cap far away from a power input side is a female maze cap, a tooth-shaped end portion of a male maze cap is matched with a tooth-shaped end portion of the female maze cap to form a maze, a male maze ring is sleeved on the roller body, in the positions where the roller body and the sealing caps are combined, the combination surfaces of the sealing caps and the roller body are respectively convex surfaces and concave surfaces, and oil output holes are formed in the lower portion of cap bodies of the sealing caps and at the bottom of the roller body.
Description
Technical field
The utility model relates to papermaking profile shell roller head technical field, is specially the displacement configuration 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 pressure release oil structure of existing papermaking profile shell roller head, its structure is seen Fig. 1, comprise 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 away from the power input 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, in described roll body 1 bottom, described seal cover 4 lid bottoms arrange output oil hole 7, the position that described seal cover 4 and described roll body 1 combine, the faying face of described roll body 1 and described seal cover 4 male and female face 12 that has been staggeredly arranged respectively.The shortcoming of this structure is: owing between roll body and labyrinth lid male and female face is set, can alleviate largely like this wearing and tearing between roll body and the end cap, but filled hydraulic oil between this male and female face, formed superposed layer, begin and finish at equipment operation, have part oil and flow out from port, thereby pollute paper, affect greatly the quality of production.
Summary of the invention
For the problems referred to above, the utility model provides the displacement configuration of papermaking profile shell roller head, and it not only can guarantee the paper CR production, and conveniently pressure release is oily, in the time of can be to the lubricating oil effective sealing of roll body inside, guarantee that roll body and end cap can overweightly not wear and tear.
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 away from the power input 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, the position that described seal cover and described roll body combine, the faying face of described roll body and described seal cover is respectively male and female face, in described roll body bottom, described seal cover lid bottom arranges output oil hole, it is characterized in that: in the described roll body oil discharge pipe is set, the exit, end of described oil discharge pipe arranges the shutoff screw, and near the power input side, described seal cover is provided with back-up ring, described back-up ring is inboard, and described roll body surface is provided with cannelure.
It is further characterized in that: the male and female face of described roll body and the male and female face of described seal cover are staggeredly arranged.
The beneficial effects of the utility model are, the oil that male and female face flows out between roll body and the seal cover can receive by the cannelure that back-up ring inner roller surface arranges, thereby oil is discharged from the bottom output oil hole, effectively prevent oil seepage and affect the quality of production of paper, and oil discharge pipe is set in the roll body, the exit, end of oil discharge pipe arranges the shutoff screw, plays the effect of timely release, prevents that effectively internal oil pressure is large.
Description of drawings
Fig. 1 is the schematic diagram of the pressure release oil structure of existing papermaking profile shell roller head;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 2, it comprises roll body 1 the utility model, 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 away from the power input side is female labyrinth lid 5, 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, described male labyrinth ring 6 is set in described roll body 1, the position that described seal cover 4 and described roll body 1 combine, the faying face of described roll body 1 and described seal cover 4 is respectively male and female face 12, in described roll body 1 bottom, described seal cover 4 lid bottoms arrange output oil hole 7, the roll body 1 interior oil discharge pipe 8 that arranges, and the exit, end of described oil discharge pipe 8 arranges shutoff screw 9, near the power input side, described seal cover 4 is provided with back-up ring 10, described back-up ring 10 inboards, and described roll body 1 surface is provided with cannelure 11; The male and female face 12 of roll body 1 and the male and female face 12 of described seal cover 4 are staggeredly arranged.
