The roller 100 that the present embodiment relates to comprises inner side main body 110, outside main body 130 and load allocation member 200.
Described inner side main body 110 alongst extends.Described inner side main body 110 plays the effect of inner side roller, can be formed by metal material.
In addition, described outside main body 130 is around described inner side main body 110.Described outside main body 130 alongst extends.Described inner side main body 110 and described outside main body 130 can have identical length.
In addition, described outside main body 130 can have hollow cylinder shape.Described outside main body 130 can be formed by metal material.At this, described outside main body 130 can be formed by identical material with described inner side main body 110.
In addition, described roller 100 can comprise multiple axle journal 120, and this axle journal 120 is separately positioned on the both ends on the length direction of described inner side main body 110.Can be further applied load to described roller 100 by described axle journal 120.
In addition, described load allocation member 200 can be configured between described inner side main body 110 and described outside main body 130.Described load allocation member 200 can alongst extend by L.
Further, the length of described load allocation member 200 can be identical with the length of described inner side main body 110, and the length of described load allocation member 200 also can be less than the length of described inner side main body 110.
Described load allocation member 200 can be contacted with described inner side main body 110 by multiple region.Further, described load allocation member 200 can be contacted with described outside main body 130 by a region.That is, described load allocation member 200 can only be contacted with described outside main body 130 by specific region.Specifically, load allocation member 200, under the state do not contacted with the central portion of inner side main body 110, contacts with the both ends of inner side main body 110 respectively.
Further, the load that described load allocation member 200 can make to put on respectively on the two or more region that contacts with the both ends of described inner side main body 110 is respectively delivered to the region contacted with outside main body 130 central portion.
For existing roller, the surface pressing deviation on central portion and both ends comparatively large (with reference to Fig. 8).Particularly, in order to reduce this surface pressing deviation, described load allocation member 200 is to contact with the both ends of inner side main body 110 respectively with under the discontiguous state of inner side main body 110 central portion.On the other hand, if load allocation member 200 contacts with the whole region of inner side main body 110, then the load major part acting on inner side main body 110 focuses on the central portion of outside main body 130, causes surface pressing deviation to strengthen further thus.
Particularly, in the present invention, load allocation member 200 contacts with the both ends of inner side main body 110, and contacts with the central portion of outside main body 130.In such an embodiment, load allocation member 200 can transmit load by elastic deformation.Specifically, when being further applied load, load is delivered to the central portion of outside main body 130 from the both ends of inner side main body 110, and in the region contacted with outside main body 130 central portion, load allocation member 200 also deforms (shape distortion).That is, with the marginal portion of outside main body 130 contact area, its contact point is kept in fact, with the mid portion of outside main body 130 contact area then main body 110 lateral bend to the inside.This degree of crook can change along with the load putting on inner side main body 110 side, but main body 130 transmits the point of load (such as laterally, with the marginal portion of outside main body 130 contact area) not along with put on inner side main body 110 side load size and change, therefore, it is possible to effectively reduce surface pressing deviation.That is, the specified point by effectively reducing surface pressing deviation carrys out main body 130 laterally and transmits load, even if thus put on roller 100 load change, the structure also without the need to changing load allocation member 200 just can reduce surface pressing deviation.
