Abstract
The utility model provides a converter trunnion bearing sealing device, comprising a sealing ring, a sealing ring gland, a dustproof stop ring, a lubricating grease hole, a spherical sealing ring, a bearing and a bearing seat, wherein the sealing ring gland is located on one side of the sealing ring; the dustproof stop ring is connected with the sealing ring gland; the lubricating grease hole is located in a cavity between the sealing ring gland and the dustproof stop ring; the spherical sealing ring is tightly combined with the sealing ring when a converter rotates; the bearing is connected with the spherical sealing ring; and the bearing seat is connected with the bearing and provided with a lubricating oil hole which is connected to the bearing. The converter trunnion bearing sealing device prevents the leakage of lubricating oil and improves the sealing performance.
Description
Technical field
The utility model relates to field of mechanical technique, particularly a kind of trunnion of converter associated sealing arrangement for bearings.
Background technology
In prior art, converter body is made with steel plate, cylindrical, and inner lining refractory by chemical reaction heat heating, does not need external heat source when blowing, is most important steelmaking equipment, for the metallurgical furnace of blow steel or blowing sulfonium, also can be used for copper, nickel smelting.
Current domestic mammoth conveter body of heater weighs hundreds of tons after charging, and As time goes on, due to basic sinking or the impact of temperature, bearing support all can produce static state in vertical and horizontal direction and misalign; And in converter rotation process, the deflection of gudgeon, the torsional deformation of backing ring, thus cause the gudgeon at two ends dynamically to misalign, and this has brought certain difficulty to bearing seal.General bearing seal structure, under this condition of misalignment, after long-time use, sealing property can decline, and causes oil leakage, causes the pollution of environment, affects the normal use of bearing.
As shown in Figure 1, it is the general converter sealed structure in Working environment.Conventionally adopt felt, rubber, tetrafluoroethylene etc. to reach the effect of sealing as sealing material.But As time goes on, because the static state of bearing support misaligns and the generation misaligning of gudgeon, as shown in Figure 2, between sealing material and gudgeon, can produce gap, meeting is serious like this shortens sealing material work-ing life or directly leaks, thereby causes the decline of sealing property.
Utility model content
The utility model designs a kind of trunnion of converter associated sealing arrangement for bearings, has solved the bearing seal performance deficiency of existing trunnion of converter, affects the normal problem using of bearing.
The utility model is for solving its technical problem, and the technical scheme of employing is:
A kind of trunnion of converter associated sealing arrangement for bearings, comprising:
Sealing-ring;
Sealing-ring gland, is positioned at described sealing-ring one side;
