Abstract
The utility model provides a locking structure for a papermaking profiling roller head. The structure is easy and convenient to assemble, an end face, which is close to a power input side, of an inner ring of a bearing is positioned by reversely extending saw teeth at the end of an inner ring of a male sealing cover; and the sealing cover on the other side is in a vertically opposite double-L shape and positions the bearing. By the locking structure, the bearing can be effectively positioned; additional thread machining is not required, so that cost is not increased; and the locking structure is convenient to assemble, so that normal operation of equipment can be guaranteed.
Description
Technical field
The utility model relates to papermaking profile shell roller head technical field, is specially the locking mechanism 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 has influence on the yield rate of paper.The locking mechanism of existing papermaking profile shell roller head, its structure is seen Fig. 1, comprise back shaft 1, back shaft 1 is installed on bearing block 3 by bearing 2, and described back shaft 1 has two, and two described back shafts 1 adopt beam type, side near roll body 4, described bearing 2 cycle surfaces contact with the annular wall of described bearing block 3 inwalls, and the outer face that described bearing block 3 is positioned at this side is zigzag, with the labyrinth ring 5 engagement formation labyrinths of its end face indentation of this side; Near the power input side, the opposite side gap of described bearing 2 is set with seal cover 6, the described seal cover 6 of this side is male seal cover 7, the profile of tooth end, outer ring of described male seal cover 7 and the profile of tooth end of described labyrinth ring 5 cooperatively interact, by round nut 8 location, described round nut 8 is set in described back shaft 1 away from the described bearing 2 inner ring end faces at the two ends of described roll body one side; The described bearing 2 of opposite side, its cycle surface away from described roll body 4 one sides contacts with seal cover 6, and the junction of the described seal cover 6 of this side and described back shaft 1 is set with felt collar 9 on the described back shaft 1.The shortcoming of the design's structure is: the bearing in the roll body both sides, side away from roll body is respectively to locate by round nut, so just require pair roller body back shaft to process screw thread, and machining screw will improve to the processing cost of back shaft, thereby cause the cost of whole equipment to improve.
Summary of the invention
For the problems referred to above, the utility model provides the locking mechanism of papermaking profile shell roller head, and this Standard is simple and convenient, can effectively realize the location, and processing cost is low.
The utility model is realized by following proposal: comprise back shaft, back shaft is installed on bearing block by bearing, described back shaft has two, two described back shafts adopt beam type, side near roll body, described bearing outer ring end face contacts with the annular wall of described bearing block inwall, and described bearing seat is zigzag in the outer face of this side, with the labyrinth ring engagement formation labyrinth of its end face indentation of this side; Near the power input side, the opposite side gap of described bearing is set with seal cover, and the described seal cover of this side is male seal cover, and the profile of tooth end, outer ring of described male seal cover and the profile of tooth end of described labyrinth ring cooperatively interact; The described bearing of opposite side, its cycle surface away from described roll body one side contacts with seal cover, the junction of the described seal cover of this side and described back shaft, be set with felt collar on the described back shaft, it is characterized in that: the described bearing cone end face of close power input side is by the anti-location of extending of the terminal sawtooth of inner ring of described male seal cover; The described seal cover of opposite side is up and down relatively L-type and locates described bearing.
The beneficial effects of the utility model are that the bearing cone end face of close power input side is by the anti-location of extending of the terminal sawtooth of inner ring of male seal cover; The seal cover of opposite side is up and down relatively L-type location bearing, then can realize effective location to bearing, need not other machining screw and increases cost, and is easy to assembly, can guarantee the normal operation of equipment.
Description of drawings
Fig. 1 is the locking mechanism schematic diagram 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, the utility model comprises back shaft 1, back shaft 1 is installed on bearing block 3 by bearing 2, back shaft 1 has two, two back shafts 1 adopt beam type, and near a side of roll body 4, bearing 2 cycle surfaces contact with the annular wall of bearing block 3 inwalls, the outer face that bearing block 3 is positioned at this side is zigzag, with the labyrinth ring 5 engagement formation labyrinths of its end face indentation of this side; Near the power input side, the opposite side gap of bearing 2 is set with seal cover 6, and this side seal lid 6 is male seal cover 7, and the profile of tooth end of male seal cover 7 and the profile of tooth end of labyrinth ring 5 cooperatively interact; The bearing 2 of opposite side, its cycle surface away from roll body 4 one sides contacts with seal cover 6, the junction of this side seal lid 6 and back shaft 1 is set with felt collar 9 on the back shaft 1, the bearing 2 inner ring end faces of close power input side are by the anti-location of extending of the terminal sawtooth of inner ring of male seal cover 7; The seal cover 6 of opposite side is up and down relatively L-type location bearing 2.
