This deep groove ball bearing's seal structure includes bearing inner race, bearing inner race, two rings shape sealing member and two shields, two sealing members and two shields symmetry respectively set up between bearing inner race and bearing inner race, and the sealing member sets up in the inboard, the shield sets up in the outside, bearing inner race outside outside -in is provided with annular dust prevention slot and second inner loop -line dust prevention slot in first, the inboard outside -in of bearing inner race is provided with first outer annular dust prevention slot and the outer loop -line dust prevention slot of second, the both ends of sealing member are blocked respectively and are located on second inner loop -line dust prevention slot and the outer loop -line dust prevention slot of second, the both ends of shield are blocked respectively and are located on first inner loop -line dust prevention slot and the first outer loop -line dust prevention slot, it is equipped with annular shaped support plates to inlay on the inside wall of sealing member. The utility model has the advantages of simple structure, leakproofness are good.
Description
Technical field
The utility model belongs to technical field of bearings, particularly 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, two lip rings and two dust covers, two Sealings and two dust covers are symmetricly set between bearing inner race and bearing outer ring respectively, and Sealing is arranged at inner side, dust cover is arranged at outside, outside bearing inner race, ecto-entad is provided with annular dustproof groove and the second inner loop-line dustproof groove in first, inside bearing outer ring, ecto-entad is provided with the first outer ring dustproof groove and the second Section of Outer Ring Line dustproof groove, the two ends of Sealing are arranged on the second inner loop-line dustproof groove and the second Section of Outer Ring Line dustproof groove respectively, the two ends of dust cover are arranged on the first inner loop-line dustproof groove and the first Section of Outer Ring Line dustproof groove respectively, the madial wall of Sealing is embedded with annular backup pad.
Compared with prior art, the utility model by arranging the first outer ring dustproof groove and the second Section of Outer Ring Line dustproof groove inside bearing outer ring, annular dustproof groove and the second inner loop-line dustproof groove in first is provided with outside bearing inner race, by Sealing and dust cover are arranged in corresponding dustproof groove respectively, thus formation double seal, 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, annular dustproof groove in first; 12, the second inner loop-line dustproof groove; 2, bearing outer ring; 21, the first outer ring dustproof groove; 22, the second Section of Outer Ring Line dustproof groove; 3, Sealing; 4, dust cover; 5, annular backup pad.
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, two lip rings 3 and two dust covers 4, two Sealings 3 and two dust covers 4 are symmetricly set between bearing inner race 1 and bearing outer ring 2 respectively, and Sealing 3 is arranged at inner side, dust cover 4 is arranged at outside, outside bearing inner race 1, ecto-entad is provided with annular dustproof groove 11 and the second inner loop-line dustproof groove 12 in first, inside bearing outer ring 2, ecto-entad is provided with the first outer ring dustproof groove 21 and the second Section of Outer Ring Line dustproof groove 22, the two ends of Sealing 3 are arranged on the second inner loop-line dustproof groove 12 and the second Section of Outer Ring Line dustproof groove 22 respectively, the two ends of dust cover 4 are arranged on the first inner loop-line dustproof groove and the first Section of Outer Ring Line dustproof groove respectively, the madial wall of Sealing 3 is embedded with annular backup pad 5.
By arranging the first outer ring dustproof groove 21 and the second Section of Outer Ring Line dustproof groove 22 inside bearing outer ring 2, annular dustproof groove 11 and the second inner loop-line dustproof groove 12 in first is provided with outside bearing inner race 1, by Sealing 3 and dust cover 4 are arranged in corresponding dustproof groove respectively, thus formation double seal, reach good sealing effect, on the madial wall of Sealing 3, be embedded with annular backup pad 5 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.
