Abstract
The utility model discloses a waterproof device for a rolling mill bearing. The waterproof device comprises a labyrinth cover and a labyrinth ring, wherein a first circular ring groove and a second circular ring groove are formed in one end surface of the labyrinth ring; a waterproof bench is arranged on the inner side wall of the first circular ring groove; the labyrinth cover is arranged on the side surface of the labyrinth ring; two annular convex blocks are fixed on the side surface of the labyrinth cover and are respectively positioned in the first circular ring groove and the second circular ring groove; two waterproof benches are respectively arranged on the two annular convex blocks; the outer ring wall of the labyrinth ring is arc-shaped; a spiral groove is formed in the outer side wall of the first circular ring groove; a waterproof ring is arranged on the labyrinth cover and is an open ring; and the waterproof ring comprises a connecting block and a waterproof plate which are fixedly connected, wherein the connecting block is fixedly arranged on the labyrinth cover and the waterproof plate is positioned at the outer side of the labyrinth ring. The waterproof device is simple in structure and strong in practicability, and can be used for reducing the amount of harmful water entering the bearing so as to prolong the service life of the bearing.
Description
Technical field
The utility model relates to a kind of roller-mill bearing water-tight device.
Background technique
Nowadays in all factories; all to use milling train by Plastic Deformation of Metal Materials; and all metallic material that need plastic deformation are all through high-temperature heating substantially; thereby metallic material is more easily out of shape; and then metallic material is out of shape with roll; when roll carries out extrusion-deformation to metallic material; conventionally can use cooling water breaker roll to carry out cooling fast; but in the process of cooling roll; have unavoidably in the bearing that part water enters into stationary roll, cause shorten the working life of bearing.
Model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, practical, reduce the water yield entering in bearing, improve the roller-mill bearing water-tight device in the working life of bearing.
The technical solution adopted in the utility model is such: a kind of roller-mill bearing water-tight device, comprise labyrinth lid and labyrinth ring, an end face of described labyrinth ring is provided with the first annular groove and the second annular groove, the madial wall of the first annular groove is provided with waterproof platform, described labyrinth lid is arranged on labyrinth ring side, lid side, described labyrinth is fixed with two annular lugs, two annular lugs lay respectively in the first annular groove and the second annular groove, on annular lug, be equipped with two waterproof platforms, the external annulus of described labyrinth ring is arc, the outer side wall of described the first annular groove is provided with spiral chute, spiral chute adopts left-handed or dextrorotation according to roll rotation direction, described labyrinth covers and is provided with waterproof ring, described waterproof ring is open loop, described waterproof ring comprises contiguous block and splash guard, contiguous block is fixedly connected with splash guard, described contiguous block is fixedly installed on labyrinth and covers, described splash guard is positioned at labyrinth ring periphery.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, simple in structure, practical, reduce the water yield entering in bearing, improve the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of A part in Fig. 1.
Fig. 3 is the structural representation of waterproof ring in the utility model.
Mark in figure: 1 is labyrinth lid, 2, labyrinth ring, 3, the first annular groove, 4, the second annular groove, 5, waterproof platform, 6, annular lug, 7, spiral chute, 8, contiguous block, 9, splash guard.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of roller-mill bearing water-tight device, comprise labyrinth lid 1 and labyrinth ring 2, an end face of described labyrinth ring 2 is provided with the first annular groove 3 and the second annular groove 4, the madial wall of the first annular groove 3 is provided with waterproof platform 5, described labyrinth lid 1 is arranged on labyrinth ring 2 sides, described labyrinth is covered 1 side and is fixed with two annular lugs 6, two annular lugs 6 lay respectively in the first annular groove 3 and the second annular groove 4, on annular lug 6, be equipped with two waterproof platforms 5, the external annulus of described labyrinth ring 2 is arc, the outer side wall of described the first annular groove 3 is provided with spiral chute 7, described labyrinth lid 1 is provided with waterproof ring, described waterproof ring is open loop, described waterproof ring comprises contiguous block 8 and splash guard 9, contiguous block 8 is fixedly connected with splash guard 9, described contiguous block 8 is fixedly installed on labyrinth lid 1, described splash guard 9 is positioned at labyrinth ring 2 peripheries.Labyrinth ring 2 is rotatable, because labyrinth ring 2 external annulus adopt helix structure, water can not amass in arc groove, and row is difficult for flowing in bearing outward, on labyrinth lid 1, waterproof ring is set again, water is with regard in more difficult inflow bearing, on the first annular groove 3 outer side walls, arrange after spiral chute 7, when labyrinth ring rotates, the water entering in the first annular groove 3 will flow out along inner spiral groove 7, greatly reduced the water yield that enters bearing, thereby improved bearing working life.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
