Abstract
The utility model discloses a deep groove ball bearing, including inner circle, outer lane, steel ball and holder, steel ball and holder correspondence be located between inner circle and the outer lane, just be provided with ball plung's pocket bulb on the holder, be provided with the store oil felt between holder surface and the outer lane inner wall, be provided with down the store oil felt between the outer periphery of holder internal surface and inner circle, just the internal surface of going up store oil felt and lower store oil felt all contacts with the steel ball, still be equipped with two sealing washers between inner circle and the outer lane, and two sealing washers are located the axial both sides of steel ball respectively, form the oil storage chamber between the outer periphery of sealing washer, inner circle, outer lane inner wall, holder and the upper and lower store oil felt, through adopting above -mentioned structure, the utility model provides an effective increase of service life's deep groove ball bearing.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to a kind of deep groove ball bearing.
Background technique
At present, the phenomenon such as existing deep groove ball bearing is in use normal causes bearing to occur burning to death because of insufficient lubrication, abnormal sound, heating, thus greatly shorten the working life of bearing.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of deep groove ball bearing that can effectively increase the service life.
For achieving the above object, the utility model provides a kind of deep groove ball bearing, include inner ring, outer ring, steel ball and retainer, described steel ball and retainer correspondence are between inner ring and outer ring, and described retainer is provided with the pocket bulb of positioning ball, store oil felt is provided with between described retainer outer surface and outer ring inwall, lower store oil felt is provided with between described retainer internal surface and inner ring outer peripheral surface, and described upper store oil felt all contacts with steel ball with the internal surface of lower store oil felt, two seal rings are also provided with between described inner ring and outer ring, and two seal rings lay respectively at the axial both sides of steel ball, described seal ring, inner ring outer peripheral surface, outer ring inwall, retainer and on, shoe cream room is formed between lower store oil felt, the centre in described retainer pocket bulb is also provided with the oil storage grooves of outwardly convex, and described oil storage grooves is also provided with the upper oil duct extending upwardly to and be connected with upper store oil felt, and extend downward the lower oil duct be connected with lower store oil felt.
The beneficial effects of the utility model are: adopt said structure, when grease abundance, upper store oil felt and lower store oil felt can store a part of grease, make Bearing inner too much can not produce temperature rise because of grease; When lubricant grease is not enough, the grease of storage can discharge again by upper store oil felt and lower store oil felt, and flows in oil storage grooves by upper oil duct and lower oil duct, carries out useful supplement, reach the object increased the service life to the lubricant grease of deficiency.
The corresponding upper groove being provided with store oil felt in stationary positioned on the inwall that the utility model can be set to described outer ring further, the corresponding lower groove being provided with store oil felt under stationary positioned on the outer peripheral surface of described inner ring.By the setting of upper groove and lower groove, the position of store oil felt and lower store oil felt in stationary positioned can be convenient to.
The inwall that the utility model also can be set to described outer ring further is also provided with dustproof groove, and the radial outer end interference of described seal ring is installed in described dustproof groove, and this spline structure is simple, easy to assembly; The radial inner end of described seal ring is provided with many and extends to the sealing lip limit sealing with the outer peripheral surface of inner ring and contact, and can be formed multi-layer sealed like this, not only can effectively prevent external dust from entering, and is convenient to people and better stores grease; Described seal ring is also embedded with Steel Skeleton, like this can the rigidity of lift-off seal circle greatly, make it have more impact resistance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
As Fig. 1, a kind of deep groove ball bearing is given shown in 2, include inner ring 1, outer ring 2, steel ball 3 and retainer 4, described steel ball 3 and retainer 4 correspondence are between inner ring 1 and outer ring 2, and described retainer 4 is provided with the pocket bulb of positioning ball 3, store oil felt 5 is provided with between described retainer 4 outer surface and outer ring 2 inwall, lower store oil felt 6 is provided with between described retainer 4 internal surface and inner ring 1 outer peripheral surface, and described upper store oil felt 5 all contacts with steel ball 3 with the internal surface of lower store oil felt 6, the corresponding upper groove 21 being provided with store oil felt 5 in stationary positioned on the inwall of described outer ring 2, the corresponding lower groove 11 being provided with store oil felt 6 under stationary positioned on the outer peripheral surface of described inner ring 1.Two seal rings 7 are also provided with between described inner ring 1 and outer ring 2, and two seal rings 7 lay respectively at the axial both sides of steel ball 3, the inwall of described outer ring 2 is also provided with dustproof groove 22, radial outer end 71 interference of described seal ring 7 is installed in described dustproof groove 22, the radial inner end of described seal ring 7 is provided with many and extends to the sealing lip limit 72 sealing with the outer peripheral surface of inner ring 1 and contact, and described seal ring 7 is also embedded with Steel Skeleton 8.Shoe cream room 9 is formed between described seal ring 7, inner ring 1 outer peripheral surface, outer ring 2 inwall, retainer 4 and upper store oil felt 5, lower store oil felt 6, the centre in described retainer 4 pocket bulb is also provided with the oil storage grooves 41 of outwardly convex, and described oil storage grooves 41 is also provided with the upper oil duct 42 that extends upwardly to and be connected with upper store oil felt 5 and extends downward the lower oil duct 43 be connected with lower store oil felt 6.By adopting said structure, the utility model provides a kind of deep groove ball bearing that can effectively increase the service life.
