Abstract
The utility model discloses a guide roller, which comprises roller shaft and a roller body which is arranged on the roller shaft, wherein the roller body and the roller shaft are rotatably matched, a wing edge is arranged on one end of the roller body, and the wing edge and the roller body are connected through an arc-shaped connecting portion. When the guide rollers is applied on the roller box, the guide roller prevents suddenly changed lateral force when passing through a node plate on a lower chord joint by arranging the arc-shaped connecting portion, and is effectively protected not to be damaged.
Description
Technical field
The utility model relates to a kind of roller, particularly relates to a kind of guide roller.
Background technology
Trolley case design in the past, roller 1-1 as shown in Figure 1 and the Trolley case 1 shown in Fig. 2, described roller 1-1 comprises roller shaft 1-1-1 and is arranged on the roller wheel body 1-1-2 on roller shaft 1-1-1, described roller wheel body 1-1-2 one end is provided with edge of a wing 1-1-3, between described edge of a wing 1-1-3 and roller wheel body 1-1-2, form step, the rolling function of Trolley case 1 is what to separate with guide function, and roller 1-1 only provides rolling function, separately increases guide plate 1-4 and leads.The chief drawback is in such design in the process of rolling, and between roller 1-1 and lower boom 1-2 track, there will be slip, and this slip suddenly change, is easy to cause the roller 1-1 near end to occur transshipping, and causes roller 1-1 to be easy to damage.As shown in Figure 3, due to the problems such as straightness accuracy of manufacturing errors and lower boom 1-2, in when design, must give between the wheel rim of roller 1-1 and lower boom 1-2 track and leave gap a.Lower boom 1-2 is coupled together by gusset plate 1-3, and in the position of gusset plate 1-3, width becomes suddenly large 32mm.Existence due to above-mentioned gap, can make at the line of centers of a certain position lower boom 1-2 and the line of centers of Trolley case 1 not parallel, in joint location, soon enter like this Trolley case 1 time, first produce and contact with guide plate 1-4, guide plate 1-4 need be to very large side force of lower boom 1-2, roller 1-1 has also just been subject to very large side force, and lower boom 1-2 could normally enter the orbit like this.The existence of this power makes end rollers 1-1 not only bear very large diametral load but also bear very large axial force, thereby is easy to damage.When section assembling bridging is constructed, can cause frequent replacing roller 1-1, to construction, bring very large puzzlement.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of guide roller is provided.This guide roller is by arc connecting portion is set, when this guide roller is applied in Trolley case, and the generation of the side force of having suddenlyd change while having avoided by lower boom joint gusset plate, actv. has been protected the unlikely damage of guide roller.
For achieving the above object, the technical solution adopted in the utility model is: a kind of guide roller, comprise roller shaft and be arranged on the roller wheel body on roller shaft, described roller wheel body and roller shaft normal-running fit, one end of described roller wheel body is provided with the edge of a wing, it is characterized in that: the described edge of a wing is connected by arc connecting portion with roller wheel body.
Above-mentioned a kind of guide roller, is characterized in that: between described roller wheel body and roller shaft, be provided with plain bearing.
Above-mentioned a kind of guide roller, is characterized in that: on described roller shaft and the both sides that are positioned at roller wheel body are all overlapped and had interstage sleeve, and described interstage sleeve and plain bearing connect.
Above-mentioned a kind of guide roller, is characterized in that: one end of described roller shaft is provided with oil nozzle, offers for lubricating oil is delivered to the oil transportation channel between plain bearing and roller shaft from oil nozzle on described roller shaft.
The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design, be easy to install.
The side force producing when 2, the utility model is by lower boom joint gusset plate is gradual change rather than sudden change; A plurality of rollers provide side force to lower boom simultaneously, have avoided first roller excessive situation of power that is hit; And simplified the structure of Trolley case, cancelled guide plate.
3, of the present utility model to realize cost low, and result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, and rationally novel in design, functional reliability is high, long service life, and result of use is good, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of guide roller as shown in Figure 4 and Figure 5, comprise roller shaft 1-1-1 and be arranged on the roller wheel body 1-1-2 on roller shaft 1-1-1, described roller wheel body 1-1-2 and roller shaft 1-1-1 normal-running fit, one end of described roller wheel body 1-1-2 is provided with edge of a wing 1-1-3, and described edge of a wing 1-1-3 is connected by arc connecting portion 1-1-4 with roller wheel body 1-1-2.
In conjunction with Fig. 6, described roller wheel body 1-1-2 adopts arc connecting portion 1-1-4 to be connected with edge of a wing 1-1-3, when lower boom 1-2 joint approach roller 1-1 time, first the gusset plate 1-3 of joint contacts with arc connecting portion 1-1-4, along with further reach, lower boom 1-2 can be raised by arc connecting portion 1-1-4, arc connecting portion 1-1-4 can give side force of lower boom 1-2 simultaneously, lower boom 1-2 lifts to such an extent that higher above-mentioned side force is larger, therefore contact and start to increasing to a certain value with the gusset plate 1-3 of lower boom 1-2 joint from roller 1-1, this process increases gradually, avoid the sudden change of above-mentioned side force.After lower boom 1-2 is raised by first roller 1-1 of end, and then the arc connecting portion 1-1-4 of roller 1-1 below also can contact with the gusset plate 1-3 of lower boom 1-2 joint, also can produce a side force, have successively a plurality of roller 1-1 and provide side force to lower boom 1-2, so just avoid first roller 1-1 to bear excessive side force, thereby damaged roller 1-1.And by described arc connecting portion 1-1-4 is set, can lead to lower boom 1-2.
To sum up, compare with common roller, guide roller described in the utility model has the following advantages: the one, and the side force producing when by lower boom 1-2 joint gusset plate 1-3 is gradual change rather than sudden change, the 2nd, a plurality of roller 1-1 provide side force to lower boom 1-2 simultaneously, avoided first roller 1-1 excessive situation of power that is hit, the 3rd, simplified the structure of Trolley case 1, cancelled guide plate 1-4.
As shown in Figure 5, between described roller wheel body 1-1-2 and roller shaft 1-1-1, be provided with plain bearing 1-1-5.In the present embodiment, described plain bearing 1-1-5 is made of copper.
As shown in Figure 4 and Figure 5, described roller shaft 1-1-1 all overlaps both sides upper and that be positioned at roller wheel body 1-1-2 and has interstage sleeve 1-1-6, and described interstage sleeve 1-1-6 and plain bearing 1-1-5 connect.
As shown in Figure 5, one end of described roller shaft 1-1-1 is provided with oil nozzle 1-1-7, offers for lubricating oil is delivered to the oil transportation channel 1-1-8 between plain bearing 1-1-5 and roller shaft 1-1-1 from oil nozzle 1-1-7 on described roller shaft 1-1-1.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belongs in the protection domain of technical solutions of the utility model.
