Abstract
The utility model relates to a bearing rainproof sealed structure, which can discharge the little water entered through the outside sealed structure from the drainage hole before the water reaching the same end of the bearing and closing with the sealed structure of bearing; and then the little water entered through the outside sealed structure can not be accumulated until approaching the seal of bearing and entering the bearing, that the bearing can be protected.
Description
Affiliated technical field
The utility model prevents when relating to a kind of bearing motive sealing that extraneous water spray from entering the sealing configuration of bearing, especially is fit to the environment that iron and steel enterprise's equipment uses cooling water and high pressure water.
Background technique
At present, known bearing waterproof method is seal ring or the labyrinth seal mode by various materials.After these sealing substance wearing and tearing, the water of outside just can enter bearing by sealing, destroys the lubricated environment of bearing, causes damage of bearings.
Summary of the invention
In order to overcome existing waterproof sealing structure does not just have desirable waterproof action after the sealing substance wearing and tearing shortcoming, the utility model provides a kind of sealing configuration of waterproof, can have under the situation of wearing and tearing at the sealing substance of bearing, guarantee that extraneous water can not enter bearing.
The scheme that its technical problem that solves the utility model adopts is: adding water proof groove and weep hole near extraneous first road (or n road) sealing with near between the sealing of bearing; after arriving the water proof groove, the feasible low amounts of water that enters by outside sealing discharges by weep hole; and have no chance by the sealing near bearing; avoid the bearing lubrication environment destroyed, thereby reached the purpose of protection bearing.
The beneficial effects of the utility model are that a small amount of extraneous water by outer side sealing is in time discharged by weep hole, makes it to be created in the effect that accumulates in time between the sealing, thereby can not enter bearing by the sealing near bearing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is an an embodiment's of the present utility model partial sectional view.
1. labyrinth seals among the figure, 2. rubber seal, 3. bearing oil hole, 4. rubber seal, the anti-waterside that 5. covers thoroughly, 6. axle sleeve, 7. spool, 8. water proof groove, 9. weep hole, 10. bearing, 11. water proof grooves, 12. weep holes.
Embodiment
The structure purpose that this patent will reach is finished in the combination of labyrinth seal in the accompanying drawings, (1), water proof groove (11), weep hole (12) jointly.When extraneous water passes through to be discharged by (12) after (1) arrives (11), have no chance between (1) and rubber seal (2), to accumulate again to enter bearing (10), thereby reach the purpose of protection bearing by (2).The combination function of the anti-waterside (5) of saturating lid, water proof groove (8), weep hole (9) is identical with the combination function of (1), (11), (12) in the accompanying drawing.Between the oil hole (3) on weep hole (12), weep hole (9) and the bearing support, there are rubber seal (2), (4) to separate respectively, avoid lubricant oil to stop up weep hole.
Claims (3)
1. the sealing configuration of bearing waterproof is that common sealing configuration is remedied sealing substance wearing and tearing back a kind of of sealing function, it is characterized in that: add weep hole between two sealing configurations of the extraneous side of Bearing support.
2. the sealing configuration of bearing waterproof according to claim 1 is characterized in that: be added with the water proof groove in the ingress of weep hole, the inlet of weep hole is opened in the lowest part of water proof groove.
3. the sealing configuration of bearing waterproof according to claim 1 is characterized in that: have sealing configuration to separate between the inlet of weep hole and the bearing oil hole.
