Abstract
The utility model discloses a bearing seat of fan, including the bearing room, pass through lid, gland, lock female, set up at the labyrinth ring who covers thoroughly, pass through and be provided with sealed felt between lid and the gland, bearing room right -hand member is covered thoroughly and is provided with the first food tray that connects, welds the first oil scraper ring of setting with the lock generatrix, bearing room left end is provided with the second and connects food tray and second oil scraper ring, it is as an organic whole that the second connects food tray and labyrinth ring to design, labyrinth ring's lower part has been offered and has been unloaded the oilhole. The slot has the advantages of reasonable structural device, connect food tray and oil scraper ring through what set up, make the bearing room form a closed loop, the oil bath is at loop -locked bottom, it is connect the food tray to catch to fall back to the oil bath to get rid of a large amount of liquid oil in whereabouts on the bearing, the liquid oil of minute quantity is through connecing food tray and the lapped fit clearance of oil scraper ring to flow through, the setting of oil scraper ring, play the damping action when making the liquid oil stream cross the clearance, labyrinth ring and felt then play two, three sealed effects, unload the setting of oilhole, it gets back to in the oil bath again to guarantee the outer drainage oil of labyrinth ring.
Description
Technical field
The utility model relates to a kind of bearing support, is specifically related to a kind of bearing fan.
Background technique
Bearing support on existing dedusting fan adopts two-seater split type structure; the lubricant oil type of cooling is forced water cooling; bearing is splash lubrication; the bearing support of this mechanism; bearing support seal failure is fast; there is a large amount of Leakage, not only cause a large amount of wastes of lubricant oil, burn out a bearing, even cause the accident shutdown.The additional felt seal of its structure many employings two ends mazy type, in blower fan High Rotation Speed, phase mutual friction between axle with labyrinth ring, wearing and tearing axle and labyrinth ring; Sintering dust district dust is large, and dust easily enters in felt and felt is hardened wearing and tearing axle journal, thus causes seal clearance to increase, thus causes bearing fan leakage of oil, and in addition, lubricants capacity is excessive, bearing support split surface poorly sealed, also easily causes bearing support leakage of oil.
Model utility content
For problems of the prior art, the purpose of this utility model is that design provides a kind of bearing fan.
Described a kind of bearing fan, comprise bearing chamber, be arranged on the transparent cover at bearing chamber two ends and gland, locknut, the labyrinth ring be arranged in transparent cover, sealing felt is provided with between described transparent cover and gland, it is characterized in that, described bearing chamber right-hand member transparent cover is spirally connected is provided with the first oil drip pan, the first gear oil ring arranged with locknut spot welding, described bearing chamber left end is provided with the second oil drip pan and second gear oil ring, described second oil drip pan and labyrinth ring are set to one, and the bottom of described labyrinth ring offers unloads oilhole.
Described a kind of bearing fan, is characterized in that the matching gap that the matching gap that described first oil drip pan and first gear oil ring overlap and the second oil drip pan and second gear oil ring overlap is 2.0mm.
Described a kind of bearing fan, is characterized in that described labyrinth ring external diameter and bearing chamber minor diameter fit are 1mm.
The utility model reasonable in design, by oil drip pan and the flinger ring of setting, bearing chamber is made to form a closed loop, oil sump is at the bottom of closed loop, bearing gets rid of fall oily being caught by oil drip pan of a large amount of liquid and fall back to oil sump, the matching gap that the liquid oil of minute quantity overlaps through oil drip pan and flinger ring flows through, the setting of flinger ring, damping function is played when making liquid oil flow through gap, labyrinth ring and felt then play two, three seals effect, unload the setting of oilhole, guarantee that the outer drainage oil of labyrinth ring comes back in oil sump.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-bearing chamber, 2-transparent cover, 3-gland, 4-locknut, 5-labyrinth ring, 6-felt, 7-first oil drip pan, 8-first gear oil ring, 9-second oil drip pan, 10-second gear oil ring, 11-unloads oilhole.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of bearing fan of the utility model, comprise bearing chamber 1, be arranged on the transparent cover 2 at bearing chamber 1 two ends and gland 3, locknut 4, the labyrinth ring 5 be arranged in transparent cover 2, be provided with between transparent cover 2 and gland 3 and seal felt 6, bearing chamber 1 right-hand member transparent cover is spirally connected and is provided with the first oil drip pan 7, the first gear oil ring 8 arranged with locknut 4 spot welding, bearing chamber 1 left end is provided with the second oil drip pan 9 and second gear oil ring 10, second oil drip pan 9 is designed to one with labyrinth ring 5, and the bottom of labyrinth ring 5 offers unloads oilhole 11.The matching gap that the matching gap that first oil drip pan 7 and first gear oil ring 8 overlaps and the second oil drip pan 9 and second gear oil ring 10 overlap is 2.0mm, and labyrinth ring 5 external diameter and bearing chamber minor diameter fit are 1mm.
The utility model first oil drip pan 7 adopts six screws to be fixed in transparent cover 2, first gear oil ring 8 is welded on locknut 4, second oil drip pan 9 is designed to one with labyrinth ring 5, the long 30mm labyrinth section internal diameter of labyrinth ring 5 and diameter of axle matching gap are 0.15mm, and the matching gap of all the other and the diameter of axle is 0.6-1mm; The minor diameter fit of labyrinth ring external diameter and reaming rear bearing room is 1mm, and coaxality is coordinated by end face and ensures.The bottom of labyrinth ring is opened an oil and is unloaded hole slot, and the internal diameter of second gear oil ring and the diameter of axle are interference fit, prevents from loosening on axle.
