Abstract
The utility model provides a sealing structure of deep groove ball bearing belongs to the bearing technology field. It has solved the current poor problem of deep groove ball bearing leakproofness. This sealing structure of deep groove ball bearing includes bearing inner race, bearing inner race and two rings shape sealing member, two sealing member symmetries set up between bearing inner race and bearing inner race, the outer fringe of sealing member has annular hem, the outside of hem has the radial bellied lug of a plurality of, the inner edge of sealing member has spherical protrudingly, it is equipped with annular shaped support plates to inlay on the inside wall of sealing member, the bearing inner race inboard is equipped with annular dust prevention slot, annular dust prevention slot's bottom is equipped with sunkenly on the bearing inner race inboard, hem on the sealing member supports that lean on in last annular dust prevention slot and the lug lies in and caves in, the bearing inner race outside is equipped with down annular dust prevention slot, the inner edge of sealing member paste tightly on the bearing inner race lateral wall and spherical protruding card solid under in the annular dust prevention slot. The utility model has the advantages of simple structure, leakproofness are good.
Description
Technical field
The utility model belongs to technical field of bearings, relates to a kind of sealing configuration of deep groove ball bearing.
Background technique
Its sealing configuration of seal deep groove ball bearing of the prior art is all the erosion relying on very large magnitude of interference to play sealing muddy water, the bearing of this structure is in the course of the work because friction torque is large, thus make the temperature rise of bearing too high, thus have influence on the life-span of bearing, in addition, intrusion for muddy water is in the course of the work unavoidable, and the reliability of bearing is low.Mechanically conventional zanjon bearing, comprises outer ring and inner ring, between outer ring and inner ring, rolling element is housed, and parallelly on the side of bearing ring is stamped two sealing covers, drive fit inside the outer rim of two sealing covers and outer ring.The problems such as at present, sealing configuration cost of production is higher, and sealing cover easily comes off, sealing effect is not good, complex structure, quality are unstable still exist.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes that a kind of structure is simple, the sealing configuration of the deep groove ball bearing of good airproof performance.
The purpose of this utility model realizes by following technical proposal: a kind of sealing configuration of deep groove ball bearing, it is characterized in that, comprise bearing inner race, bearing outer ring and two lip rings, two Sealings are symmetricly set between bearing inner race and bearing outer ring, the outer rim of Sealing has circular fold, the outside of flanging has the projection of several radial protrusions, the Inner edge of Sealing has hemisphere jut, the madial wall of Sealing is embedded with annular backup pad, annular dustproof groove is provided with inside bearing outer ring, inside bearing outer ring, the bottom of upper annular dustproof groove is provided with depression, flanging on Sealing is resisted against in annular dustproof groove and projection is positioned at depression, lower annular dustproof groove is provided with outside bearing inner race, the inner edge of Sealing is adjacent on bearing inner race outer side wall and hemisphere jut is fastened in lower annular dustproof groove.
Compared with prior art, the utility model by arranging annular dustproof groove inside bearing outer ring, lower annular dustproof groove is provided with outside bearing inner race, in the depression being arranged in upper annular dustproof groove by the projection on Sealing and hemisphere jut respectively and in lower annular dustproof groove, thus reach good sealing effect, on the madial wall of Sealing, be embedded with annular backup pad simultaneously, play the effect of supporting sealing member, good stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, bearing inner race; 11, lower annular dustproof groove; 2, bearing outer ring; 21, upper annular dustproof groove; 22, cave in; 3, Sealing; 31, flanging; 32, projection; 33, hemisphere jut; 4, dunnage.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the sealing configuration of this deep groove ball bearing comprises bearing inner race 1, bearing outer ring 2 and two lip rings 3, two Sealings 3 are symmetricly set between bearing inner race 1 and bearing outer ring 2, the outer rim of Sealing 3 has circular fold 31, the outside of flanging 31 has the projection 32 of several radial protrusions, the Inner edge of Sealing 3 has hemisphere jut 33, the madial wall of Sealing 3 is embedded with annular backup pad 4, annular dustproof groove 21 is provided with inside bearing outer ring 2, inside bearing outer ring 2, the bottom of upper annular dustproof groove 21 is provided with depression 22, flanging 31 on Sealing 3 is resisted against in annular dustproof groove 21 and projection 32 is positioned at depression 22, lower annular dustproof groove 11 is provided with outside bearing inner race 1, the inner edge of Sealing 3 is adjacent on bearing inner race 1 outer side wall and hemisphere jut 33 is fastened in lower annular dustproof groove 11.
By arranging annular dustproof groove 21 inside bearing outer ring 2, lower annular dustproof groove 11 is provided with outside bearing inner race 1, in the depression 22 being arranged in upper annular dustproof groove 21 by the projection 32 on Sealing 3 and hemisphere jut 33 respectively and in lower annular dustproof groove 11, thus reach good sealing effect, on the madial wall of Sealing 3, be embedded with annular backup pad 4 simultaneously, play the effect of supporting sealing member 3, good stability.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
