Two, background technology
At present, lower fulcrum coupling unit in the air supporting machine that uses in the sewage disposal between outer tube lower end and the rotating shaft, because of its structure design unreasonable, exist following shortcoming: because motor exists certain concentricity with connecting of rotating shaft, rotating shaft is longer again, it can produce swing when running up, the bearing of existing lower fulcrum coupling unit can not adapt to the swing that the rotating shaft high speed rotating produces; The lower fulcrum coupling unit is for a long time in sewage, and its used mechanical seal can not effectively stop sewage to enter bearing, causes bearing very quick-wearing and damage, has influenced the normal operation of air supporting machine; Though design has the oil lubrication device in addition, owing to entering of sewage, lubricant effect is undesirable.
Three, summary of the invention
The purpose of this utility model is for the air supporting machine provides a kind of novel lower fulcrum coupling unit, and its can automatic aligning, adapts to the swing that the rotating shaft high speed rotating produces, sealing, high lubricating effect, and long service life can guarantee the normal operation of air supporting machine and simple in structure.
For achieving the above object, the technical scheme that the utility model is taked is: be made up of outer tube, casing seat, lower ball cover, self-lubricating self-aligning bearing device, rotating shaft, rotating shaft etc.The lower end of outer tube is fixed on the casing seat, lower ball cover covers on the downside that sleeve pipe is done, rotating shaft is contained in the casing seat by self-lubricating self-aligning bearing device, and the lower end of rotating shaft is stretched out lower ball cover and adorned impeller, between self-lubricating self-aligning bearing device and lower ball cover filter screen is housed.
Because the utility model has adopted self-lubricating self-aligning bearing device, it can satisfy rotating shaft when high speed rotating swing and carry out self-lubricating, between lower ball cover and self-lubricating self-aligning bearing device, be provided with filter screen, filter screen can stop the impurity in the sewage, only allow water to enter between self-lubricating self-aligning bearing and outer tube and the rotating shaft, self-lubricating self-aligning bearing device is played cooling effect, and saved former oil lubrication device and mechanically-sealing apparatus.Therefore, the utlity model has can automatic aligning, adapts to the swing that the rotating shaft high speed rotating produces, good sealing effect, and lubricant effect is good, and long service life can guarantee the normal operation of air supporting machine, characteristics such as simple in structure.

Five, embodiment
Accompanying drawing is embodiment of the present utility model, is made up of outer tube 1, casing seat 2, lower ball cover 3, self-lubricating self-aligning bearing device 4, rotating shaft 5, filter screen 6 etc.The lower end of outer tube 1 is fixed on casing seat 2 upper ends, lower ball cover 3 covers on casing seat 2 ground downsides, rotating shaft 5 is contained in the casing seat 2 by self-lubricating self-aligning bearing device 4, lower ball cover 3 is stretched out in its lower end, between self-lubricating self-aligning bearing device 4 and lower ball cover 3, filter screen 6 is housed, can saves former oil lubrication device and mechanically-sealing apparatus like this.
The structure formation of self-lubricating self-aligning bearing device 4 is a lot.The self-lubricating self-aligning bearing device 4 of present embodiment is made up of spheroplast 41, spheroid seat 42, self-lubricating medium etc.Be provided with shaft hole in the spheroplast 41, the outer side of spheroplast 41 is protruding sphere, also is provided with the lubricant medium hole 43 that is communicated with shaft hole and outer side in the spheroplast 41.The medial surface that cooperates with spheroplast 41 of spheroid seat 42 is concave spherical surface correspondingly.Rotating shaft 5 is contained in the shaft hole of spheroplast 41, and can freely rotate, spheroplast 41 is contained in the spheroid seat 42 by its protruding sphere, and can swing up and down, can not rotate with rotating shaft 5, spheroplast 41 is fixed on (as passing through shrink-fit) in the casing seat 2, and the self-lubricating medium is contained in the lubricant medium hole 43 of spheroplast 41.
The material of spheroid seat 42, spheroplast 41 is a corrosion resistant material, and present embodiment adopts xantal, and the erosion resistance of self-lubricating self-aligning bearing device 4 is strong like this.
Self-lubricating medium kind is also more, and the self-lubricating medium of present embodiment is poly-tetrafluoro, and when this rotated in rotating shaft 5 and spheroplast 41, poly-tetrafluoro was entered between rotating shaft 5 and the spheroplast 41 by the lubricant medium hole 43 of spheroplast 41, forms lubricant film.
When guaranteeing running, the self-lubricating self-aligning bearing is not subjected to axial force, and present embodiment is provided with gap II45 between the upper surface of spheroplast 41 and rotating shaft 5 flanges.
Filter screen 6 also can replace with reinforced seal, and when adopting reinforced seal, reinforced seal is arranged between lower ball cover 3 and the rotating shaft 5.
Therefore, owing to be provided with self-lubricating self-aligning bearing device 4, the swing that it can produce with rotating shaft 5 high speed rotating and aligning, adapted to the swing of rotating shaft 5, and the energy self-lubricating, sealed structure adopts filter screen 6 or reinforced seal, can stop that the impurity in the sewage enters, water enters then can play cooling effect, and spheroplast 41, spheroid seat 42 adopt xantal in addition, have improved erosion resistance.Therefore, the utlity model has and can automatic aligning adapt to the swing that rotating shaft 5 high speed rotating produce, good sealing effect, characteristics such as lubricant effect is good, and long service life has guaranteed the normal operation of air supporting machine, and is simple in structure.
