Abstract
The utility model discloses a kind of bearing of being convenient to fill lubricant oil, comprise bearing outer ring, bearing inner race, steel ball and axis hole, described steel ball is arranged between bearing outer ring and bearing inner race, and described axis hole is arranged on the central position of bearing inner race; Described bearing inner race is near a plurality of oil storage tanks of the inner casting of direction of steel ball, and opening is all set on each oil storage tank, on described opening, one-way valve is set, described in each, on oil storage tank, a side relative with opening all arranges oilhole, this oilhole runs through a side of bearing inner race, and oilhole outlet port arranges piston.Reach the convenient object of filling lubricant oil and economizing on resources.
Description
Technical field
The utility model relates to mechanical field, particularly, relates to a kind of bearing of being convenient to fill lubricant oil.
Background technique
At present, the many aspects of bearing for living, but in order to prevent the impact of dust on bearing, many design bearing are enclosed, in order to reduce the friction between bearing, fill many lubricant oil between the steel ball of bearing.But along with the prolongation of service time, it is dry that lubricant oil slowly becomes, the friction between steel ball is increased, thereby affect the working life of bearing.The bearing using on bicycle, general several years just need to be added lubricant oil again to bearing, and the existing bearing for bicycle interpolation lubricant oil need to be removed whole bearing, and the one, the dismounting used time is longer; The 2nd, after removing, install very complicated.Or have directly replace with new bearing, waste resource.
Model utility content
The purpose of this utility model is, for the problems referred to above, proposes a kind of bearing of being convenient to fill lubricant oil, to realize convenient advantage of filling lubricant oil.
For achieving the above object, the technical solution adopted in the utility model is:
Be convenient to fill a bearing for lubricant oil, comprise bearing outer ring, bearing inner race, steel ball and axis hole, described steel ball is arranged between bearing outer ring and bearing inner race, and described axis hole is arranged on the central position of bearing inner race; Described bearing inner race is near a plurality of oil storage tanks of the inner casting of direction of steel ball, and opening is all set on each oil storage tank, on described opening, one-way valve is set, described in each, on oil storage tank, a side relative with opening all arranges oilhole, this oilhole runs through a side of bearing inner race, and oilhole outlet port arranges piston.
Further, the diameter of described opening is 2mm.
Further, the number of described oil storage tank is no less than 4.
The technical solution of the utility model has following beneficial effect:
The technical solution of the utility model, by a plurality of oil storage tanks and oilhole are set, when bearing is added to lubricant oil, the connecting rod that axis hole is connected is placed on motor, then by oilhole, lubricant oil is added in each oil storage tank, use stopper that oilhole is clogged, then electric rotating machine, utilizes centripetal force that lubricant oil is added between bearing outer ring and bearing inner race.Thereby avoided removing whole bearing or replacing whole bearing.Reached the object that convenience is filled lubricant oil and economized on resources.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the bearing structure schematic diagram of being convenient to fill lubricant oil described in the utility model embodiment.
By reference to the accompanying drawings, in the utility model embodiment, reference character is as follows:
1-oilhole; 2-bearing outer ring; 3-opening; 4-bearing inner race; 5-axis hole; 6-steel ball; 7-one-way valve; 8-oil storage tank.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of bearing of being convenient to fill lubricant oil, comprises bearing outer ring 2, bearing inner race 4, steel ball 6 and axis hole 5, and steel ball 6 is arranged between bearing outer ring 2 and bearing inner race 4, and axis hole 5 is arranged on the central position of bearing inner race 4; Bearing inner race 4 is near 4 oil storage tanks 8 of the inner casting of direction of steel ball 6, and on each oil storage tank 8, opening 3 is all set, one-way valve 7 is set on opening 3, a side relative with opening 3 on each oil storage tank 8 all arranges oilhole 1, this oilhole 1 runs through a side of bearing inner race 4, and oilhole 1 outlet port arranges piston.Oil storage tank 8 can add according to design, also can be designed as 5,6 or 7.But can not be less than 4 and can not be greater than 12.
Wherein, the diameter of opening 3 is 2mm.
Oil storage tank 8 is for being arranged on the groove of the sealing of bearing inner race 4, and oil storage tank 8 can be circle, also can be for square, and when it is circular, its radius should be chosen between 1cm to 1.3cm.And while being square, its height and width are 1cm.And oilhole 1 runs through a side of bearing inner race 4.Be the inside that oil storage tank 8 is positioned at bearing inner race 4.Be equivalent to a larger bubble, and the direction of close steel ball 6.
Such as the trailing wheel of bicycle, when filling new lubricant oil, only chain need be taken off, then, by being placed on motor of whole trailing wheel level, utilizing the whole trailing wheel High Rotation Speed of driven by motor, thereby lubricant oil is flow between steel ball from oil storage tank.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
