Abstract
The utility model discloses a reciprocating shaft sealing device which solves the problems that an existing reciprocating shaft sealing structure is short in service life, difficult to detach and the like. The reciprocating shaft sealing device is characterized in that a hoop (3), sliding sealing plates (8) and a fixed sealing plate (11) are respectively divided into two symmetric parts along the center lines, the two sliding sealing plate bodies (8) are connected as a whole through a sliding connecting plate (7) and is arranged on a reciprocating shaft (18) in a sleeved mode, the two hoop bodies (3) are fixed to the reciprocating shaft (18) through a connecting bolt (7) and a positioning bolt (16), and the four corners of the hoop are provided with a pressing device composed of bolts (4), spring blocking pieces (5) and springs (6) so that the sliding sealing plate (8) can be tightly fixed to the surface of the fixed sealing plate (11). The reciprocating shaft sealing device has the advantages of being reasonable in structure, quick to assemble and disassemble, convenient to maintain, good in sealing performance, long in service life and the like, and has extensive popularization and application value.
Description
One, technical field
The utility model belongs to machinery, relates in particular to a kind of reciprocating shaft sealing device.
Two, background technique
At present, at machinery industry, often occur that axle two ends stretch out casing, axle is done parallel to-and-fro motion at axis relatively, and axle and tank ends often need to seal.Common way is all that fixed seal ring and sliding ring are set on the axle of tank ends, by clip frame, is fixed, and realizes shaft sealing.Because wearing and tearing between sliding ring and axle are very fast, need frequent maintain and replace sliding ring, but dismantlement work more complicated had both affected machine work efficiency, increased again the workload of service worker, bring larger trouble to the daily production of enterprise.
Three, summary of the invention
The purpose of this utility model be for market provide a kind of rational in infrastructure, handling fast, the reciprocating shaft sealing device of little, the long service life of good seal performance, labor intensity.
The technical solution of the utility model is: it comprises the installation angle bar on reciprocal axle, seal diaphragm, main spindle box body and the part such as the seal arrangement that consists of clip, slipper seal plate, fixing seal plate, described clip, slipper seal plate and fixing seal plate are all divided into symmetrical two from center line, be that clip and slipper seal plate are divided into symmetrical two from center line substantially horizontal, fixing seal plate is divided into symmetrical two from center line Vertical direction.Two blocks of fixing seal plates are fixedly installed in and are installed on angle bar by fixed connecting plate and connecting bolt, two blocks of slipper seal plates are bolted integral snare on reciprocal axle by sliding connection plate, and be provided with soft seal with the circular hole edge that is back and forth coupling tactile, two clips are fixed on reciprocal axle by connecting bolt and holding down bolt, its four jiaos are provided with the hold down gag consisting of bolt, spring stop piece and spring, make slipper seal plate be close to the surface of fixing seal plate.And above described fixing seal plate, be provided with the tank filler sleeve with oil connection, play the lubricated and sealing double action between slipper seal plate and fixing seal plate.
The beneficial effects of the utility model are: owing to traditional clip, slipper seal plate and fixing seal plate being divided into symmetrical two, by assembled can becoming one, reciprocal axle is sealed, thereby it is simple and efficient to make to keep in repair, more change jobs, not only can save a large amount of engineering time, and rational in infrastructure, good seal performance, make sealing plate working life obtained increasing substantially, tool has a wide range of promotion and use value.
Below in conjunction with accompanying drawing, the utility model is further described.
Four, accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the left TV structure schematic diagram of the utility model.
In figure: 1,2,4 is bolt, 3 is clip, and 5 is spring stop piece, 6 is spring, and 7 is sliding connection plate, and 8 is slipper seal plate, 9 is fixed connecting plate, and 10 is oil connection, and 11 is fixing seal plate, 12 is asbestos washer, 13 is, 17 connecting bolts, and 14 for installing angle bar, 15 is soft seal, 16 is holding down bolt, and 18 is reciprocal axle, and 19 is seal diaphragm.
Five, embodiment
As shown in the figure, get metallic material and make clip 3, sliding connection plate 7, slipper seal plate 8, fixed connecting plate 9 and fixing seal plate 11, clip 3 and slipper seal plate 8 and fixing seal plate 11 are all divided into symmetrical two from center line.Fixing seal plate 11 is fixedly installed in and is installed on angle bar 14 by fixed connecting plate 9 and connecting bolt 13, and fill asbestos washer 12 between fixing seal plate and seal diaphragm 19, two blocks of symmetrical slipper seal plates 8 link into an integrated entity snare by sliding connection plate 7 on reciprocal axle 18 by bolt 2, and are provided with soft seal 15 at the circular hole edge contacting with reciprocal axle 18.Two symmetrical clips 3 are fixedly mounted on reciprocal axle 18 by connecting bolt 17 and holding down bolt 16, its four jiaos are provided with the hold down gag consisting of bolt 4, spring stop piece 5 and spring 6, make slipper seal plate 8 surfaces be close to the surface of fixing seal plate 11, the top of fixing seal plate 11 is provided with the tank filler sleeve with oil connection 10, lubricating grease enters by tank filler sleeve, plays the lubricated and sealing double action between slipper seal plate 8 and fixing seal plate 11.While implementing the utility model, when needs are changed slipper seal plate 8 and fixing seal plate 11, only need unclamp holding down bolt 16 and connecting bolt 17, two symmetrical clips 3 are taken off on reciprocal axle 18, then turn on the bolt 13 on bolt 2 and the fixed connecting plate 9 in sliding connection plate 7, can take off the slipper seal plate 8 and the fixing seal plate 11 that are worn, again the slipper seal plate 8 more renewing and fixing seal plate 11, then with connecting bolt 17 and holding down bolt 16, clip 3 is connected and is fixedly mounted on reciprocal axle 18, then tight a bolt 4, spring 6 can make the internal surface of slipper seal plate 8 be close to the surface of fixing seal plate 11, reach reciprocal axle 18 carrying out the seal action of axial reciprocating while moving.Have rational in infrastructure, load and unload the advantages such as quick, easy to maintenance, good seal performance, long service life, there is application value widely.
