Abstract
The utility model discloses a rolling bearing and dynamic compulsory sealing component of a horizontal roller, comprising a V-typed sealing ring, a retaining cover, an oil retaining ring, an oil slinger and a pressing block, wherein, the rolling bearing is arranged at the end of a rotating shaft, the retaining cover, a stuffy cover, the rotating shaft, the pressing block and the V-typed sealing ring, etc., thus forming a sealing zone. The oil retaining ring and the oil slinger are arranged in the sealing zone. When the lubricant passes through an oil inlet and enters into the moving rolling bearing, the lubricant forms lubrication through the rolling bearing with the drive of oil pressure and axial force, the redundant lubricant enters into an oil cavity formed by the retaining cover and the rotating shaft, and the lubricant carries out a second oil throw-off by the function of the oil retaining ring, thus finally forming an oil film. The oil film is closed when in normal work, so the debris outside is hard to enter into the rolling bearing, thus realizing the dynamic compulsory sealing. The lubricant failing in forming the oil film is ejected from an oil pipeline.
Description
Technical field
The utility model relates to a kind of bearing seal assembly, the dynamic forced seal assembly of particularly a kind of roller mill rolling bearing for sleeping in.
Background technique
At present, the packing seal of filling type, extrusion pressing type elastomeric seal, flexural mode elastomeric seal, labyrinth seal or spiral seal or the like are mostly adopted in common bearing seal, realize the passive radial sealing of bearing, and realize the dynamic axial sealing of rolling bearing with disc.The oil mass instability that often this dynamic seal (packing) throws away in the working procedure, sealing does not reach zero leakage.The grease of seepage often will cling dust in air, makes bearing increase abrasive forces in operation process, weakens flexibility, thereby reduces the life-span.
Summary of the invention
For overcoming the oil mass instability that throws away when existing rolling bearing seals, sealing does not reach the deficiency of zero leakage, the utility model provides a kind of dynamic forced seal assembly of rolling bearing, comprises V-shaped seal ring, door, flinger ring, disc, briquetting, rolling bearing, stifle, end cap etc.Make the oil mass that throws away in its working procedure stable, and can form secondary and get rid of oil, guarantee that fully oil film forms, and realizes dynamic seal (packing).
The technological scheme that its technical problem that solves the utility model adopts is: rolling bearing is installed in rotary shaft end, and door, stifle, rotatingshaft, briquetting, v-ring etc. form sealing area.Establish flinger ring, disc in the sealing area.When lubricant oil passes through filler opening, enter in the rolling bearing of motion, under the drive of oil pressure and axial force, lubricant oil forms lubricated through rolling bearing, unnecessary lubricant oil enters in the oil pocket that is formed by door and rotatingshaft, forms secondary and get rid of oil under the effect of flinger ring, forms one deck oil film.Oil film sealing during proper functioning, external impurities is difficult to enter in the bearing, realizes dynamic forced seal.The lubricant oil that does not form oil film is then discharged from oil outlet tube.
The beneficial effects of the utility model are, have realized the dynamic forced seal of rolling bearing, reach zero leakage, have improved the going slick property of bearing, have increased working life.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1 is oil outlet tube, and 2 is rotatingshaft, and 3 is V-shaped seal ring, and 4 is flinger ring, and 5 is door, 6 is disc, and 7 is bolt, and 8 is that briquetting one, 9 is a sunk screw, and 10 is that briquetting two, 11 is a bolt, 12 is stifle, and 13 is rolling bearing, and 14 is bolt, and 15 is end cap, and 16 is oil inlet pipe.
Embodiment
Briquetting 1 is connected with briquetting 2 10 usefulness sunk screws 9 among the figure, door 5, flinger ring 6 and briquetting one 8 usefulness bolts 7 connect, stifle 12 is connected with briquetting 2 10 usefulness bolts 11, end cap 15 usefulness bolts 14 are fixed on axle head, disc 4, V-shaped seal ring 3 with special construction is enclosed within on the rotatingshaft 2 with rolling bearing 13, axially being fixed by disc 4 and end cap 15 of rolling bearing 13.When lubricant oil enters in the zone that is formed by stifle 12, end cap 15 and rolling bearing 13 by oil inlet pipe 16, under the drive of oil pressure and axial force, after lubricant oil process rolling bearing 13 formed and lubricates, unnecessary lubricant oil then entered in the sealing area that is formed by rotatingshaft 2, V-shaped seal ring 3, door 5, flinger ring 6, briquetting 1 etc.Because disc 4 is interference fitted on the rotatingshaft 2, along with rotatingshaft 2 rotates together, lubricant oil is after disc 4 gets rid of oil, and secondary gets rid of oil under the effect of flinger ring 6, forms one deck oil film.The lubricant oil that does not form oil film can only be discharged from oil outlet tube 1 because the effect of V-shaped seal ring 3 can't be overflowed.During proper functioning, because the oil film sealing has stoped various dust impurity to enter rolling bearing 13, guarantee the normal safe handling of rolling bearing 13, thereby realized the forced seal of rolling bearing, reached zero leakage, improve the going slick property of bearing, increased working life.
Claims (2)
1. a roller for sleeping in grinds the dynamic forced seal assembly of rolling bearing, and it is characterized in that: it comprises V-shaped seal ring, door, flinger ring, disc, briquetting, rolling bearing, stifle, end cap, and rolling bearing is installed in rotatingshaft one end.
2. according to the dynamic forced seal assembly of the described a kind of roller mill rolling bearing for sleeping in of claim 1, it is characterized in that: form the oil film dynamic seal (packing) between disc and the flinger ring.
