Description
Technical field
The invention belongs to technical field of automobile accessories, more particularly to a kind of bearing roller.
Background technology
Bearing roller is the important component in bearing, and usual roller is arranged on retainer, and retainer is each for separating
Roller, keep roller spacing equal, make load mean allocation, bearing roller turns between bearing inner race and bearing outer ring during use
It is dynamic so as to the function of realizing bearing inner race and outer ring mutually rotates, due to bearing roller all the time with retainer and bearing internal external circle
Contact and phase mutual friction, be so easily caused bearing roller and easily wear, in addition, existing bearing roller also there is：Surely
Qualitative difference, bearing capacity is poor, and service life is short, the problems such as roller lubrication degree difference.
In order to solve the problems, such as that prior art is present, people have carried out long-term exploration, it is proposed that miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of bearing roller, [application number：201320162382.9], including roller sheet
Body, roller body are hollow-sphere structures roller, and two corresponding through holes are provided between roller body outer surface and inwall.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, for example, solving bearing rolling to a certain extent
Following defect also at least be present in the problem of sub- end is easy to wear, production cost is high, still, the program:Stability is poor, bearing roller
End outer circumferential is easy to wear, and roller lubrication degree is poor, and stationarity is poor when circumferentially rotating.
The content of the invention
Regarding the issue above, the present invention provides a kind of design more reasonable, the nonabradable axle of roller end
Bearing roller.
To reach above-mentioned purpose, present invention employs following technical proposal：This bearing roller, including cylindrical roller
Body, it is characterised in that described rolling body at least one end center has blind hole, and described blind hole is connected with coaxially to be set with rolling body
The communicating passage put, described rolling body circumferentially have some annular oil grooves, and are provided with described annular oil groove some with connecting
The oilhole that circulation passage is connected, be respectively equipped with the end face at described rolling body both ends it is some be uniformly distributed in a circumferential direction and
Pit on the outside of blind hole, and pit quantity on described rolling body both ends end face is equal and shifts to install.Blind hole can prevent
Only rolling body end wear and can be used for stores lubricating oil, and pit can prevent that terminal body end outer circumferential from wearing and both ends
Pit shifts to install can be so that stability be good when rolling body circumferentially rotates.
In above-mentioned bearing roller, described pit is tapered, and the width outside described pit is to the width of bottom
Degree diameter diminishes.
In above-mentioned bearing roller, described rolling body both ends are equipped with blind hole, and the depth size of described blind hole
More than the depth size of pit.
In above-mentioned bearing roller, the quantity of the pit on described rolling body both ends end face is four, and described
Rolling body one end end face on pit projection on an opposite end and surround to form loop configuration with the pit positioned at the end end face.
In above-mentioned bearing roller, the quantity of described annular oil groove is axially uniformly distributed for two and along rolling body.
In above-mentioned bearing roller, the oilhole in each annular oil groove is in a discrete distribution each along helix.
In above-mentioned bearing roller, projection of each oilhole on rolling body cross section be respectively positioned on same circumference and
It is uniformly distributed on circumferencial direction.It this architecture enhance the intensity of rolling body and be advantageous to the diffusion of lubricating oil, and can also cause
Rolling body rotates more steady.
In above-mentioned bearing roller, described rolling body both ends outer circumferential is equipped with arc angling portion.
Compared with prior art, it is the advantages of this bearing roller：It is simple in construction, the mill of rolling body end can be reduced
Damage, stability is good, and bearing capacity is good, and service life length, roller lubrication degree is good, and stationarity is good when roller rotates.
Brief description of the drawings
Fig. 1 is structural representation provided by the invention.
Fig. 2 is structure sectional view provided by the invention.
In figure, rolling body 1, blind hole 11, communicating passage 12, annular oil groove 13, oilhole 14, pit 15, arc angling portion 16.
Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, this bearing roller, including cylindrical rolling body 1, the both ends outer circumferential of rolling body 1 are all provided with
There is arc angling portion 16, at least one end center of rolling body 1 has blind hole 11, and blind hole 11 is connected with what is be coaxially disposed with rolling body 1
Communicating passage 12, rolling body 1 is circumferential to have some annular oil grooves 13, and in annular oil groove 13 provided with some with the phase of communicating passage 12
The oilhole 14 of connection, it is respectively equipped with the end face at the both ends of rolling body 1 and some are uniformly distributed in a circumferential direction and are located at blind hole 11
The pit 15 in outside, and the quantity of pit 15 on the both ends end face of rolling body 1 is equal and shifts to install, blind hole 11 here can prevent
The end wear of rolling body 1 and can be used for store lubricating oil, pit 15 can prevent the end outer circumferential of terminal body 1 wear and both ends
Pit 15 shift to install can be so that stability be good when rolling body 1 circumferentially rotates.
Specifically, the pit 15 in the present embodiment is tapered, and the width outside pit 15 to the width diameter of bottom becomes
Small, the both ends of rolling body 1 here are equipped with blind hole 11, and the depth size of blind hole 11 is more than the depth size of pit 15.Wherein,
Here the quantity of the pit 15 on the both ends end face of rolling body 1 is four, and the pit 15 on one end end face of rolling body 1 projects
Surround to form loop configuration on an opposite end and with the pit 15 positioned at the end end face.Preferably, annular oil groove 13 here
Quantity is two and is axially uniformly distributed along rolling body 1.
The oilhole 14 in each annular oil groove 13 in the present embodiment is in a discrete distribution each along helix, and each oil
Projection of the hole 14 on the cross section of rolling body 1 is respectively positioned on same circumference and is uniformly distributed in a circumferential direction, and this moon enhances
The intensity of rolling body 1 and the diffusion for being advantageous to lubricating oil, and it is more steady make it that rolling body 1 rotates.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can be made various modifications or supplement to described specific embodiment or be replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
Although rolling body 1, blind hole 11, communicating passage 12, annular oil groove 13, oilhole 14, pit have more been used herein
15th, the term such as arc angling portion 16, but it is not precluded from the possibility using other terms.Using these terms just for the sake of more
Easily describe and explain the essence of the present invention；Being construed as any additional limitation is all and the spiritual phase of the present invention
Run counter to.
