Abstract
The utility model discloses a deep groove ball bearing, which belongs to the field of bearings and aims at overcoming the shortcoming that service life of the existing bearing is shortened due to the fact that coarse oversize particles are apt to permeate into the inside of the bearing and damage a rolling body. The deep groove ball bearing comprises an inner ring, an outer ring, a rolling body, a retainer, a sealing ring and a dustproof cover. The inner ring and the outer ring are respectively provided with a groove, the rolling body is arranged in the grooves between the inner ring and the outer ring, and the retainer enables to the rolling body to maintain a corresponding position between the inner ring and the outer ring. A step is arranged on the inner side of the outer ring, and the sealing ring is sleeved on the inner ring and abuts against the step of the outer ring. The dustproof cover comprises a dustproof framework and a covering piece, the dustproof framework is arranged to be a hollow boss, an embedding groove is arranged on the inner ring of the covering piece, the boss of the dustproof framework faces outwards and is embedded in the embedding groove, the dustproof cover is sleeved on the inner ring and abuts against the lateral wall of the outer ring, and an oil guide hole is arranged on the side of an outer ring body. A screw hole is arranged on the inner ring, and a location screw is installed in the screw hole in screwing mode and abuts against the boss of the dustproof framework. The deep groove ball bearing is capable of effectively preventing external coarse oversize particle impurities from permeating into the inside of the bearing, improves bearing performance, prolongs service life and simultaneously greatly strengthens adaptability to working environment.
Description
Technical field
The utility model belongs to field of bearings, and is especially relevant with a kind of deep groove ball bearing.
Background technique
Be operated in the bearing in the rugged environment, its sealability requires very high.In existing bearing,, generally adopt the form of bilateral limit sealing in order to improve the sealability of bearing; But after long-term the use,, rub with the seal ring Long contact time because extraneous big particle impurity gets into; Seal ring is caused greatly damage; Sealability descends thereupon, and the rolling element in big particle impurity and then the infiltration bearing internal injury bearing reduces the working life of bearing greatly.
The model utility content
The purpose of the utility model is exactly to exist the easy internal injury rolling element that infiltrates of big particle in order to overcome existing bearing, and then the defective of reducing working life, provides a kind of big particle that can effectively stop to infiltrate inner deep groove ball bearing.For this reason, the utility model adopts following technological scheme:
A kind of deep groove ball bearing comprises inner ring, outer ring, rolling element, retainer, seal ring and dust cover, and inner ring and outer ring all are provided with groove; Rolling element places the groove between inner ring and the outer ring, and with retainer rolling element is placed corresponding position of maintenance between inner ring and the outer ring, and the inboard of outer ring is provided with step; Ring set is on the inner ring and be pressed against on the step of outer ring; Dust cover is set in inner ring and is resisted against on the sidewall of outer ring, can prevent effectively that impurity from getting into bearing internal injury rolling element, and it is characterized in that: side, described outer ring is provided with oil guiding hole; Behind this oil guiding hole adding lubricant oil; The life-span of bearing is strengthened greatly, and described dust cover comprises dustproof skeleton and covers sheet that dustproof skeleton is arranged to cannular boss; Cover the interior ring of sheet and be provided with telescoping groove, the boss of dustproof skeleton is flush-mounted in the brand-new dust cover of composition in this telescoping groove outwardly.
Said inner ring is provided with tapped hole, and the positioning screw spinning and is resisted against on the boss of dustproof skeleton in this tapped hole, and position-limiting action is built in protection, makes protecting cover more reliable with cooperating of Internal and external cycle.
Use the utility model can reach following beneficial effect: can stop effectively that extraneous big particle impurity infiltrates bearing inside, improve the performance of bearing, prolong the working life of bearing, also strengthen adaptability simultaneously greatly to working environment.
Description of drawings
Fig. 1 is the sectional drawing of the utility model master apparent direction.
Embodiment
Be described in detail below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the utility model comprises inner ring 8, outer ring 9, rolling element 4, retainer 3, seal ring 2 and dust cover, and inner ring 8 all is provided with groove with outer ring 9; Rolling element 4 places the groove between inner ring 8 and the outer ring 9, and with retainer 4 rolling element 4 is placed corresponding position of maintenance between inner ring 8 and the outer ring 9, and the inboard of outer ring 9 is provided with step; Seal ring 2 is set on the inner ring 8 and is pressed against on the step of outer ring 9; Dust cover comprises dustproof skeleton 6 and covers sheet 5 that dustproof skeleton 6 is arranged to cannular boss, covers to encircle in the sheet 5 to be provided with telescoping groove; The boss of dustproof skeleton 6 is flush-mounted in the brand-new dust cover of composition in this telescoping groove outwardly; Dust cover is set in inner ring 8 and is resisted against on the sidewall of outer ring 9, can prevent effectively that impurity from getting into bearing internal injury rolling element 4, and 9 sides, outer ring are provided with oil guiding hole 1; Behind this oil guiding hole 1 adding lubricant oil, strengthened in the life-span of bearing greatly; Inner ring 8 is provided with tapped hole, and positioning screw 7 spinnings and are resisted against on the boss of dustproof skeleton 6 in this tapped hole, and position-limiting action is built in protection, make protecting cover more reliable with cooperating of Internal and external cycle.
