In a preferred embodiment of the present invention, the thickness of cover plate matches with external diameter described in the size of described step and two.
In a preferred embodiment of the present invention, on described inner ring, offer rivet taper hole, in described rivet taper hole, sunk head rivet is installed.
In a preferred embodiment of the present invention, the radial internal clearance of described roller roller bearing is 0.005 ~ 0.02mm.
In a preferred embodiment of the present invention, the circumferential clearance of described roller is 0.5mm.
The invention has the beneficial effects as follows: a kind of roller roller bearing of the present invention, this bearing is by two cover plates, inner ring, outer ring and roller are formed to an entirety, simple when bearing is installed and used, reliable and convenient, while guaranteeing to install, roller can not drop, the lubricant oil by semicircle oilhole, cam being taken up when roller work enters between roller and interior raceway and outer raceway, plays lubricated effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of roller roller bearing of the present invention.
Fig. 2 is that the A-A of a kind of roller roller bearing of the present invention is to sectional view.
In accompanying drawing, the mark of each parts is as follows: 1, outer ring; 2, interior raceway; 3, step; 4, inner ring; 5, outer raceway; 6, roller; 7, rivet taper hole; 8, sunk head rivet; 9, cover plate; 10, semicircle oilhole.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises: a kind of roller roller bearing, comprise: outer ring 1, inner ring 4 and two cover plates 9, the inwall of described outer ring 1 is provided with interior raceway 2, two sides of described outer ring 1 are respectively equipped with step 3, the thickness of the degree of depth of described step 3 and described cover plate 9 matches, and has guaranteed can not affect after described cover plate 9 riveteds the flexibility of revolution of bearing.
Described inner ring 4 is arranged in described outer ring 1, the outer wall of described inner ring 4 is provided with outer raceway 5, between described interior raceway 2 and described outer raceway 5, be folded with roller 6, on described inner ring 4, offer rivet taper hole 7, described rivet taper hole 7 is for installing described sunk head rivet 8, described in making two, cover plate 9, described inner ring 4, described outer ring 1 and described roller 6 are fixed into an entirety, by the tapped hole on described inner ring 4, bearing are fixed on support, prevent whole bearing transfer.
Two described cover plate 9 riveteds are fixed on the both sides of described inner ring 4, the external diameter of described cover plate 9 is greater than the internal diameter of described outer ring 1, form rib, described rib coordinates with described step, two described cover plates 9 are clamped described inner ring 4, described outer ring 1 and described roller 6, prevent that described roller 6 from dropping out, on the excircle of described cover plate 9, offer several semicircle oilholes 10, described in several semicircle oilhole 10 with the formal distribution of decile on the excircle of described cover plate 9.
In the present embodiment, on the excircle of described cover plate 9, offer three semicircle oilholes 10, three described semicircle oilholes 10 with the formal distribution of trisection on the excircle of described cover plate 9, when described semicircle oilhole 10 is worked for roller, the lubricant oil being taken up by cam is entered between described roller 6 and described interior raceway 2 and described outer raceway 5, thereby play lubricated effect.
The radial internal clearance of described roller roller bearing is 0.005 ~ 0.02mm, the circumferential clearance of described roller 6 is 0.5mm, thereby guaranteed to carry more described roller 6 simultaneously, further avoid described inner ring 4 phenomenon excessive with the local pressure of described outer ring 1, alleviate wearing and tearing, extended working life.
Below the working principle of a kind of roller roller bearing of the present invention is described in detail.
When installation, outer ring 1 is connected with inner ring 4, and install roller 6 between the interior raceway 2 of outer ring 1 and the outer raceway 5 of inner ring 4, match with the rivet taper hole 7 on inner ring 4 by sunk head rivet 8, two cover plates 9 carry out riveted with the both sides of inner ring 4, form two ribs, on cover plate 9 excircles, have the semicircle oilhole 10 of trisection, in the time that working, roller the lubricant oil being taken up by cam can be entered between roller 6 and interior raceway 2 and outer raceway 5 by semicircle oilhole 10, play lubrication, the size of the step 3 on 1 inner circumference of outer ring and the thickness of two cover plates 9 match with external diameter, guarantee can not affect after two cover plate 9 riveteds the flexibility of revolution of bearing.
When use, by the tapped hole on inner ring 4, bearing is fixed on support, prevents whole bearing transfer.
Compared with prior art, a kind of roller roller bearing of the present invention forms a whole 5 bearing partss by riveted, install simple, quick, without the risk of doing over again, falling apart, owing to there being semicircle oilhole, make it fully lubricated, improve the working life of bearing, improve 2 ~ 3 times the working life of bearing, because radial internal clearance is 0.005 ~ 0.02mm, the circumferential clearance of roller is 0.5mm, guarantee that the roller number of carrying increases simultaneously, further avoid the excessive phenomenon of Internal and external cycle local pressure, alleviated wearing and tearing, further improved the working life of 50% left and right.
