Abstract
The utility model provides a supporting structure for a papermaking profiling roller head. The supporting structure for the papermaking profiling roller head can achieve full cooling for an inner bearing, guarantee that the bearing is not prone to being seized easily, and guarantee the normal operation of a roller body. The supporting structure for the papermaking profiling roller head comprises the roller body which is installed on a bearing pedestal through a conical roller bearing, and end faces at the two ends of an outer ring of the conical roller bearing are respectively contacted with a sealing cover which is sleeved on the roller body. One ends of two end faces of an inner ring of the conical roller bearing are close to a roller neck of the roller body, the other ends of the two end faces of the inner ring of the conical roller bearing are positioned through screw nuts, the screw nuts are sleeved on the roller body, and an input passageway and an output passageway for lubricating oil are arranged in a cover body of the sealing cover.
Description
Technical field
The utility model relates to papermaking profile shell roller head technical field, is specially the supporting construction 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 supporting construction 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 circular cone roller bearing 2, and the end face at the two ends of described circular cone roller bearing 2 outer rings contacts with seal cover 4 respectively, and described seal cover 4 is set in described roll body 1, two end faces of described circular cone roller bearing 2 inner rings, the one end is near the roll neck of described roll body 1, and then by nut 5 location, described nut 5 is set in described roll body 1 to the other end.The shortcoming of this supporting construction is exactly: because the roll body rotation, and bear load, bearing generates heat easily like this, and whole seal cover surrounds fully, and bearing internal cause excess Temperature, lubricating oil can not get effectively replenishing, effective lubrication and cooling, thus the bearing seizure phenomenon appears easily.
Summary of the invention
For the problems referred to above, the utility model provides the supporting construction of papermaking profile shell roller head, and it can realize the abundant cooling to its internal bearings, guarantees that bearing phenomenon can not occur killing easily, guarantees the normal operation of roll body.
The utility model is realized by following proposal: it comprises roll body, described roll body is installed on bearing block by the circular cone roller bearing, the end face at the two ends of described circular cone roller bearing outer ring contacts with seal cover respectively, described seal cover is set in described roll body, two end faces of described circular cone roller bearing cone, the one end is near the roll neck of described roll body, the other end is then located by nut, described nut sleeve is loaded on described roll body, it is characterized in that: the input channel and the output channel that are provided with lubricating oil in the described seal cover lid.
It is further characterized in that: the seal cover lid is the labyrinth lid, it is divided into three parts, mid portion is Xiong Migonggai, it is set in the outside of described circular cone roller bearing, both sides are respectively female labyrinth ring, described two female labyrinth rings are set in roll body, and the profile of tooth end of its profile of tooth end of described female labyrinth ring and described Xiong Migonggai complements each other to form the labyrinth.
After the utility model adopts said structure, be provided with input channel and the output channel of lubricating oil in the seal cover lid, can input online lubricating oil like this, guarantee the lubrication and cooling to bearing, between be filled with extreme pressure lubricant, thereby so that end cap is in suspended state, the wearing and tearing between roll body and the end cap have been alleviated so largely, guarantee normal operation and the normal service life of roll body and end cap, and the seal cover lid adopts the labyrinth form, be conducive to the storage to lubricating oil, further guaranteed the normal lubricated and in time cooling of bearing.
Description of drawings
Fig. 1 is the sealed structural representation of existing papermaking profile shell roller head;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises roll body 1, roll body 1 is installed on bearing block 3 by circular cone roller bearing 2, the end face at the two ends of circular cone roller bearing 2 outer rings contacts with seal cover 4 respectively, and seal cover 4 is set in roll body 1, two end faces of circular cone roller bearing 2 inner rings, the one end is near the roll neck of roll body 1, then by nut 5 location, nut 5 is set in roll body 1 to the other end, is provided with input channel 6 and the output channel 7 of lubricating oil in seal cover 4 lids; Seal cover 4 lids are the labyrinth lid, it is divided into three parts, mid portion is male labyrinth lid 8, it is set in the outside of circular cone roller bearing 2, both sides are respectively female labyrinth ring 9, two female labyrinth rings 9 are set in roll body 1, and the profile of tooth end of female labyrinth ring 9 its profile of tooth ends and male labyrinth lid 8 complements each other to form the labyrinth.
