The utility model provides a kind of bearing type roller, comprises roller shaft, outer roller body, bearing inner race, rolling element and dust-proof cover.Wherein, bearing inner race is set on the axis of rolling; Rolling element is arranged between outer roller body and bearing inner race; On outer roller body inner ring surface, near the position of self end face, be respectively provided with the fixed groove of an annular; Two dust-proof cover are separately positioned in fixed groove, and are provided with axis hole at least one dust-proof cover, and the axis of rolling passes from axis hole.
In bearing type roller provided by the utility model, adopt bearing structure, can be applicable to the operating mode of high temperature, high rotating speed and heavy duty; The dust-proof cover that is arranged at both sides isolates from the dust in environment outside bearing structure, avoids dust to enter in bearing structure, causes component wear; Meanwhile, roller shaft, dust-proof cover and outer roller body surround an inner chamber that only has fine gap, avoid the oiling agent of overflowing in bearing structure to leak in a large number, have reduced the use amount of oiling agent.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the bearing type roller that Fig. 1 provides for the utility model embodiment;
Fig. 2 is the right elevation of Fig. 1;
The structural representation of the bearing type roller that Fig. 3 provides for another embodiment of the utility model.
In above Fig. 1-3:
Embodiment
The utility model embodiment discloses a kind of for bearing type roller that can long time running at high temperature, many dust atmospheres, dryouies the problem that roller shaft and roller body are killed to solve existing roller lubricant.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, in bearing type roller provided by the utility model, comprise roller shaft 1, outer roller body 2, bearing inner race 3, rolling element 4 and dust-proof cover 5.
Bearing inner race 3 is set on the axis of rolling 1.
On the inner ring surface of outer roller body 2, be provided with two annular fixed grooves, lay respectively at inner ring surface near the position of outer roller body 2 both sides end faces.
Dust-proof cover 5 is arranged among fixed groove, for the axis of rolling 1 is passed, at least one dust-proof cover 5, is provided with axis hole.
In the bearing type roller that the present embodiment provides, adopt bearing structure, can be applicable to the operating mode of high temperature, high rotating speed and heavy duty.The dust-proof cover 5 that is arranged at both sides isolates from the dust in environment outside bearing structure, avoids dust to enter in bearing structure, causes component wear.Meanwhile, roller shaft 1, dust-proof cover 5 surround cavity with outer roller body 2, and this cavity only leaves space between the axis of rolling 1 and dust-proof cover 5, avoids the oiling agent of overflowing in bearing structure to leak in a large number, has reduced the use amount of oiling agent.
It will be appreciated by those skilled in the art that, between bearing inner race 3 and rolling element 4, relatively rotate, require to have better crocking resistance.And roller shaft 1 is not rubbed, do not need to use the material identical with bearing inner race 3, thereby both are set to split type structure.Where necessary, those skilled in the art also can be set to integral structure by roller shaft 1 and bearing inner race 3.
Further, in the bearing type roller providing at above-described embodiment, also comprise lubricated piece 6.As shown in Figure 2, lubricated piece 6 and rolling element 4 are co-located between outer roller body 2 and bearing inner race 3, and in the process with rolling element 4 associated movements, the lubricated external roller body 2 of piece 6, bearing inner race 3 and rolling element 4 are lubricated.Preferably, in the bearing type roller providing at above-described embodiment, lubricated piece 6 is graphite block.Same as preferred, rolling element 4 is steel ball.
When the larger load of carrying, the roller of one-sided cantilever support can produce distortion under the effect of larger moment of flexure.In order to address this problem, in the bearing type roller that another embodiment of the utility model provides, be positioned on the dust-proof cover 5 of both sides and be all provided with axis hole so that by both sides simultaneously pair roller axle 1 support.
In order further to improve the sealability between dust-proof cover 5 and outer roller body 2, preferably, in the bearing type roller providing at the utility model above-described embodiment, the edge of dust-proof cover 5 is provided with to the sealing lip of side turnover.
Sealing lip to side turnover has certain elasticity, and after dust-proof cover 5 is installed in fixed groove, sealing lip flicks to side, makes dust-proof cover 5 and outer roller body 2 close contacts, thereby improves sealability.
As shown in Figure 3; same in order to improve the seal protection to bearing structure; in the bearing type roller providing in another embodiment of the utility model; on roller shaft 1, be provided with annular seal groove; the edge of seal closure 5 upper shaft holes extend in sealing groove; form easy labyrinth seal structure, prevent that dust from entering bearing type roller inner.
Preferably, in the technological scheme providing at above-described embodiment, on the outer roller body 2 of bearing type roller, be at least provided with one rib 21.
