Abstract
The utility model relates to a sealing assembly with a deep groove ball bearing, which comprises a sealing ring, a steel bone frame, a dustproof cap, an outer ring, an inner ring and a steel ball. The sealing component change the traditional single lip contact type sealing assembly into a double lip contact type sealing assembly; the steel bone frame is embraced by the sealing ring; the outside diameter of the sealing ring is in interference contact with the outer ring; the inside diameter of the is in interference contact with the inner ring; the sealing ring is also in interference contact with the dustproof cap. The beneficial effect of the utility model is in that: the sealing assembly largely surpasses the dustproof, waterproof and airproof performance than the traditional sealing assembly, which always ensures good sealing function during the running process or at static state. Therefore, the utility model has higher reliability comparing with traditional single lip contact type sealing assembly.
Description
Technical field
The utility model relates to technical field of bearings, particularly a kind of deep groove ball bearing black box.
Background technique
Rolling bearing both ends of the surface at newly-developed all are equipped with corresponding black box.Its effect is to keep the lubricating grease (oil) of bearing inside in use can not run off on the one hand, guarantees that bearing is in lubricating status, is that the dust or the harmful gas in the protection bearing external world can not enter bearing cavity on the other hand, in case bearing is caused damage.Most widely used is the seal ring of rubber or engineering plastics, and the sealing configuration of its seal ring is varied, and its sealing effect is also different.Gapped between seal ring and the rotating shaft, claim noncontact seal, the gap is more little, and sealing effect is good more, but allows the rotating speed of axle more little; Otherwise on the contrary then.Gapless between seal ring and the rotating shaft, claim contact seal, the area of contact of seal ring contact lip is big more, and sealing effect is good more, but allows the rotating speed of axle more little, otherwise on the contrary then.The main research contents of technical field, research and development are applied to the corresponding seal arrangement under the different operating modes exactly, and the integration of sealing assembly material and associated lubrication fat etc.China follows international trend, has developed several big class bearings of deep groove ball bearing, water pump bearing, railway tapered roller bearing, needle bearing and cylindrical roller bearing with seal ring, deep groove ball bearing output maximum wherein, and application surface is the widest.In the recent period China stuffing box bearing quality testing result is seen that China's sealed bearing structure design problem is bigger according to national Technical Board, sealing effect is bad, and leakage fat phenomenon is more serious, and the user has strong complaints.By analysis, main cause is that the existing seal ring project organization of China is unreasonable, traditional single sealing lip structural type adopts more, add accuracy of manufacturing not the plateau because of causing.Therefore, the trend of China's bearing seal technology Future Development should be: be representative with the deep groove ball bearing, carry out the sealing technique test, searching develops into many sealing lips from single sealing lip, develop optimal seal coil structures such as noncontact seal from contact seal, be to improve the bearing seal life-span, under the exploitation high temperature condition or the seal ring of under the harmful gas condition, working lay solid technical foundation
Summary of the invention
The purpose of this utility model is to propose a kind of deep groove ball bearing black box, and sealing assembly sealing effect and reliability are considerably beyond the conventional seals assembly.
The technical solution of the utility model is, a kind of deep groove ball bearing black box, form by seal ring 1, Steel Skeleton 2, dust cover 3, outer ring 4, inner ring 5 and steel ball 6, the sealing assembly changes lips contact seal assembly into by single lipped joint touch black box, Steel Skeleton 2 is contained by seal ring 1, the external diameter of seal ring 1 contacts with outer ring 4 interference, and the internal diameter of seal ring 1 contacts with inner ring 5 interference, and seal ring 1 contacts with dust cover 3 interference again.
The beneficial effects of the utility model are: the sealing assembly is in dustproof, waterproof, and the aspect of performance of gas-tight is considerably beyond the conventional seals assembly.No matter new black box is at operation process, and still static process all has the characteristics of good airproof performance.Therefore, new lips contact seal assembly has higher reliability than traditional single lipped joint touch black box
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, seal ring, 2, Steel Skeleton, 3, dust cover, 4, the outer ring, 5, inner ring, 6, steel ball.
Embodiment
As Fig. 1, black box is made up of seal ring 1, Steel Skeleton 2, dust cover 3, outer ring 4, inner ring 5, steel ball 6, the sealing assembly changes lips contact seal assembly into by single lipped joint touch black box, Steel Skeleton 2 is contained by seal ring 1, the external diameter of seal ring 1 contacts with outer ring 4 interference, the internal diameter of seal ring 1 contacts with inner ring 5 interference, and seal ring 1 contacts with dust cover 3 interference again.The deep groove ball bearing that has used this black box has improved 34% than traditional bearing load capacity under harsh lubricating condition, the life-span prolongs 2.7 times, leak the fat amount and reduce 22%, anti-dust performance improves 36%, water-proof performance improves 29%, and the gas-tight performance improves 18%, and the reliability height, is easy to safeguard.My company has formed batch process at present, and obtains user's extensive approval.
Claims (1)
