the novel sealing device for the cellular wheel shaft end comprises a main shaft and end covers at two ends, and is characterized in that a sealing filler shaft sleeve is fixedly connected to the outer side of each end cover, an annular gap is reserved between the sealing filler shaft sleeve and the main shaft, sealing filler is filled in the annular gap and is tightly pressed by a gland, each gland is tightly screwed on the corresponding end cover, a hole for the main shaft to penetrate out is formed in each gland, and the main shaft rotates relative to the gland; and a dry oil lubrication nozzle is fixedly connected to each sealing filler shaft sleeve at a position corresponding to the sealing filler.
Preferably, a limiting boss is formed on the inner wall of each sealing filler shaft sleeve, an annular protrusion extending to the corresponding sealing filler shaft sleeve limiting boss is formed on the inner side of each gland, and the sealing filler is locked by the corresponding gland annular protrusion after being plugged into the limiting boss from outside to inside. The scheme can facilitate the installation and replacement of the sealing filler, and can effectively prevent the sealing filler from sliding randomly in the gap between the sealing filler shaft sleeve and the main shaft.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, by arranging the dry oil lubricating nozzle and the like, a proper amount of lubricating grease is injected from the dry oil lubricating nozzle periodically, so that the sealing effect of the sealing filler is prevented from being influenced due to the adhesion of powder, the service life of the sealing filler is prolonged, and the problems of air leakage and material leakage at the end of the cell wheel shaft are thoroughly solved.

FIG. 2 is a left side schematic view of the present utility model;
FIG. 3 is a schematic view of the position of the annular protrusion on the gland according to the present utility model;
FIG. 4 is a schematic view of the position structure of a limiting boss on a sealing filler shaft sleeve according to the present utility model;
the device comprises a gland, a ring-shaped bulge, a fixing bolt, a sealing filler, a dry oil lubricating nozzle, a main shaft, an end cover, a sealing filler shaft sleeve, a limit boss and a limit boss, wherein the gland, the annular bulge, the fixing bolt, the sealing filler and the limit boss are arranged in sequence, and the seal filler shaft sleeve is fixedly connected with the main shaft.
Detailed Description
The utility model will now be further elucidated with reference to the drawings. The following are preferred embodiments of the present utility model, and are not intended to limit the scope of the utility model. Any equivalent or similar substitution without departing from the concept of the utility model shall fall within the scope of the present application. The following Wen Weixiang sections, all made using prior art techniques.
As shown in figures 1-4, the novel sealing device for the end of the cell wheel shaft comprises a main shaft 5, an end cover 6, a sealing filler shaft sleeve 7, sealing filler 3, a gland 1, a fixing bolt 2 and a dry oil lubrication nozzle 4, wherein the two ends of the main shaft 5 are in rotary fit in a conventional mode. The outer side of each end cover 6 is welded with a sealing filler shaft sleeve 7, each sealing filler shaft sleeve 7 is positioned at the periphery of the corresponding end of the main shaft 5, an annular gap is reserved between the sealing filler shaft sleeves 7, an annular limiting boss 7.1 is processed on the inner wall of each sealing filler shaft sleeve 7 (the limiting boss is formed by designing the diameter of the inner wall of each sealing filler shaft sleeve 7, which is close to the outer side, to be relatively smaller, and the diameter of the inner wall of each sealing filler shaft sleeve 7, which is close to the end cover 6, so that the inner wall of each sealing filler shaft sleeve 7 forms a limiting boss), sealing filler 3 is filled in the annular gap at the position of the limiting boss 7.1 and positioned between the sealing filler shaft sleeve 7 and the main shaft 5, in order to enable the sealing filler 3 to be compressed by the gland 1, an annular bulge 1.1 extending to the limiting boss 7.1 of the corresponding sealing filler shaft sleeve 7 is formed at the inner side of each gland 1, the sealing filler 3 is plugged into the position from outside to the inside, the corresponding gland 1 annular bulge 1.1 is used for propping, then each gland 1 is screwed on the corresponding end cover 6 through two fixing bolts 2, so that the corresponding sealing filler shaft sleeve 7 is screwed on the corresponding end cover 6, the corresponding gland sleeve 7 is sealed, and the end cover 1 is opened, and the main shaft 5 is compressed, and each sealing filler shaft 5 is pressed relatively tightly, and the main shaft 5 is pressed; and a dry oil lubrication nozzle 4 is fixedly connected to the peripheral wall of each sealing filler shaft sleeve 7 and corresponds to the position of the sealing filler 3, and the outer end of the dry oil lubrication nozzle 4 is positioned outside the peripheral wall of the sealing filler shaft sleeve 7.
The utility model is specifically arranged between end covers 6 on two sides of the dividing wheel and a supporting bearing of the main shaft 5, and plays a role in lubricating sealing materials and sealing fillers. Compared with the existing sealing device for the shaft ends of the division wheel, the sealing device has the greatest characteristics that the dry oil lubrication nozzle 4 is added on the sealing filler shaft sleeve 7, and a proper amount of lubricating grease is regularly injected from the dry oil lubrication nozzle 4 through the gun head with the sharp nozzle, so that the sealing property of the sealing filler 3 is enhanced, the long-term effect of the sealing filler in use is prolonged, and the problem of air leakage and material leakage of the shaft ends of the division wheel is thoroughly solved. The utility model has simple structure, low economic cost and good use effect, avoids the influence of on-site ash leakage and material leakage on environmental sanitation, greatly reduces the labor cost of maintenance personnel for replacing the shaft end sealing filler, has more obvious air locking and material locking effects, effectively protects on-site environmental sanitation, reduces the frequency of replacing the sealing filler, and has certain popularization significance.
