Abstract
The utility model discloses a roller with double buffer layers. The roller comprises a bearing, wherein an interlayer covers outside the bearing; an outer layer covers outside the interlayer; specific to the aim of increasing the adsorption force between the interlayer and the outer layer, the outer circumferential surface of the interlayer is provided with recesses which are uniformly distributed; the recesses are semispherical or semi-cylindrical; similarly, the outer circumferential surface of the interlayer is provided with bumps which are uniformly formed; the bumps are semi-spherical or semi-cylindrical; preferably, the interlayer is made from polyurethane; and preferably, the outer layer is made of nylon. The roller with double buffer layers has the beneficial effects of simple structure, low cost, prolonging of the service life of the roller and lowering of noise.
Description
Technical field
The utility model relates to a kind of roller.
Background technology
Existing silent contact roller is to cover a cushion coat in the outer ring of bearing again, to reduce noise, make the rolling of bearing more steady, can be widely used in elevator door, on the family expenses sliding door, the roller of this cushion coat is after use after a while, under the impact of gravity, can deform, the time has been grown, noise can strengthen, and stationarity is affected.
The utility model content
The utility model provides a kind of roller of double-buffering layer according to above deficiency, adopts the double-buffering layer structure, prolongs the life-span of roller, can reduce further noise.
The technical solution of the utility model is:
A kind of roller of double-buffering layer comprises bearing, and bearing is coated with interlayer outward, is coated with skin outside interlayer.
In order to increase interlayer and outer field absorption affinity, the outer circumference surface of described interlayer is provided with uniform indent.
Described indent is hemispherical or half round post.
In like manner, the outer circumference surface of described interlayer is provided with uniform evagination.
Described evagination is hemispherical or half round post.
As preferably, described interlayer is made by polyurethane.
As preferably, described skin is made by nylon.
That the roller of a kind of double-buffering layer of the utility model has is simple in structure, cost is low, the beneficial effect of prolonging service life of roller, reduction noise.
Description of drawings
Fig. 1 is overall structure sectional view of the present utility model.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
As shown in Figure 1, a kind of roller of double-buffering layer comprises bearing 3, is coated with interlayer 1 outside the bearing 3, is coated with outer 2 outside interlayer 1.
The outer circumference surface of interlayer 1 is provided with uniform indent 11, and indent 11 is hemispherical or half round post.
As another embodiment, interlayer 1 cross section can also be U font groove.
As another embodiment, the outer circumference surface of interlayer 1 can also be provided with uniform evagination, and evagination is hemispherical or half round post.
As another embodiment, indent 11 and evagination can also be reticulate patterns, and its purpose is all identical, in order to increase interlayer and outer field absorption affinity.
