Abstract
The utility model discloses a kind of bearing for bicycle, 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 encloses oil pipe near the inner casting one of direction of steel ball, and a plurality of openings are set in the periphery of this oil pipe, on described opening, one-way valve is set, and a side of described bearing inner race arranges oil guiding hole, and the bottom of this oil guiding hole is communicated with oil pipe.Avoided removing whole bearing or replacing whole bearing.Reached and added the object that lubricant oil is simple and economize on resources.
Description
Technical field
The utility model relates to mechanical field, particularly, relates to a kind of bearing for bicycle.
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 for bicycle, realizes and adds the simple advantage of lubricant oil.
For achieving the above object, the technical solution adopted in the utility model is:
For a bearing for bicycle, 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 encloses oil pipe near the inner casting one of direction of steel ball, and a plurality of openings are set in the periphery of this oil pipe, on described opening, one-way valve is set, and a side of described bearing inner race arranges oil guiding hole, and the bottom of this oil guiding hole is communicated with oil pipe.
Further, the diameter of described opening is 2mm.
Further, the number of described opening is for being no less than 4.
The technical solution of the utility model has following beneficial effect:
The technical solution of the utility model, by oil pipe and oil guiding hole are set, when bearing is added to lubricant oil, the connecting rod that axis hole is connected is placed on motor, then by oil guiding hole, lubricant oil is added in oil pipe, use stopper that oil guiding hole 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 and added the object that lubricant oil is simple and economize 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 structural representation of the bearing for bicycle described in the utility model embodiment.
By reference to the accompanying drawings, in the utility model embodiment, reference character is as follows:
1-oil guiding hole; 2-bearing outer ring; 3-opening; 4-bearing inner race; 5-axis hole; 6-steel ball; 7-one-way valve; 8-oil pipe.
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 for bicycle, 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 encloses oil pipe 8 near the inner casting one of direction of steel ball 6, and 4 openings 3 are set in the periphery of this oil pipe 8, and one-way valve 7 is set on opening 3, and a side of bearing inner race 4 arranges oil guiding hole 1, and the bottom of this oil guiding hole 1 is communicated with oil pipe 8.The number of opening 3 can arrange according to demand, setting more, and while adding lubricant oil, interpolation more even.But the number of opening is for being no less than 4.
Wherein, the diameter of opening 3 is 2mm.The one-way valve 7 being arranged on opening 3 prevents that lubricant oil blows back in oil pipe at ordinary times.Oil pipe 8, bearing inner race 4, oil guiding hole 1 and opening 3 are all that direct pouring forms when producing.Oil pipe 8 is positioned at the inside of bearing inner race 4, and the diameter of oil pipe 8 is 1 to 1.5cm, and the Thickness Ratio of itself and bearing inner race 4 is less than 1/2.
When adding lubricant oil, such as rear wheel, can directly trailing wheel be placed directly on motor, make the whole trailing wheel of driven by motor High Rotation Speed on motor, thereby drive bearing inner race 4 rotations.
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.
Claims (3)
1. for a bearing for bicycle, 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; It is characterized in that, described bearing inner race encloses oil pipe near the inner casting one of direction of steel ball, and a plurality of openings are set in the periphery of this oil pipe, on described opening, one-way valve is set, and a side of described bearing inner race arranges oil guiding hole, and the bottom of this oil guiding hole is communicated with oil pipe.
2. the bearing for bicycle according to claim 1, is characterized in that, the diameter of described opening is 2mm.
