In preferred embodiment of the utility model, the thickness of cover plate matches with external diameter described in the size of described step and two.
In preferred embodiment of the utility model, on described inner ring, offer rivet taper hole, in described rivet taper hole, sunk head rivet is installed.
In preferred embodiment of the utility model, the radial internal clearance of described roller roller bearing is 0.005 ~ 0.02mm.
In preferred embodiment of the utility model, the circumferential clearance of described roller is 0.5mm.
The beneficial effects of the utility model are: a kind of roller roller bearing of the utility model, this bearing is by two cover plates, inner ring, outer ring and roller are formed to an integral body, 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 during 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 utility model.
Fig. 2 is that the A-A of a kind of roller roller bearing of the utility model 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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the utility model is embodiment comprise: 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 having guaranteed can not affect the flexibility of revolution of bearing after described cover plate 9 riveteds.
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 integral body, 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 avoided described inner ring 4 phenomenon excessive with the local pressure of described outer ring 1, alleviate wearing and tearing, extended working life.
