In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts there is provided a kind of Combined roll, comprising:
Base, comprise integrated disk and the rotating shaft being vertically installed in described disk inner side surface, the medial axis of described disk and described rotating shaft overlaps, and described disk is also provided with the screw running through its inside and outside bi-side, described screw is uniformly distributed and center line is positioned at circumferentially same;
Roller bearing, is set in described rotating shaft;
Circular closure, center is provided with multiple through hole, pin is through described through hole and embed the exterior edge face of described rotating shaft, and the diameter of described circular closure is identical with described disk and be greater than the external diameter of described roller bearing, and the inner side surface of described disk and described circular closure is formed and the draw-in groove of guide rail.
In combinations thereof formula roller, the inner of described rotating shaft is provided with the first boss, and the side of the inner ring of described first boss and described roller bearing offsets.
In combinations thereof formula roller, the inner side surface of described circular closure is provided with fastening protrusion and the second boss, described fastening protrusion and described second boss offset with the exterior edge face of described rotating shaft, the another side of described inner ring respectively, and described through hole is arranged on described fastening protrusion.
In combinations thereof formula roller, the thickness of described fastening protrusion is greater than the thickness of described second boss.
In combinations thereof formula roller, the number of described roller bearing is two.
In combinations thereof formula roller, the cross section of described draw-in groove is rectangle.
The utility model is made up of base, roller bearing and capping, structure is simple, easy for installation, roller can be bolted on the position of needs, and base and capping are located at the two ends of roller bearing, makes it keep lengthwise position to fix, the inner side surface of disk and capping forms the draw-in groove with guide rail, simple installation, cost is low, is easy to change during maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the decomposing schematic representation of the utility model forward;
Fig. 3 is the reverse decomposing schematic representation of the utility model.
Embodiment
The utility model provides a kind of Combined roll, simple installation, and cost is low.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of Combined roll, comprises base 10, roller bearing 20 and circular closure 30.
As shown in Figures 2 and 3, base 10 comprises integrated disk 11 and is vertically installed in the rotating shaft 12 of disk 11 inner side surface, the medial axis of disk 11 and rotating shaft 12 overlaps, disk 11 is also provided with to be run through in it, the screw of outer bi-side, screw is uniformly distributed and center line is positioned at circumferentially same, in the present embodiment, screw is set to shoulder hole, and macropore 13, aperture 15 is opened respectively on the inner side surface and outer side surface of disk 11, for disk 11 is fixed on special position, the nut of bolt can be made to be placed in macropore 13, thus keep the smooth of the inner side surface of disk 11, facilitate the installation of other component.
Roller bearing 20 is set in rotating shaft 12, and roller bearing 20 comprises inner ring and outer ring, and inner ring and rotating shaft 12 are interference fit, outer ring is used for bearing guide rail, roller along with moving element move time, outer ring opposite rail rolls, thus moving element is run according to pre-determined route on guide rail.
The center of circular closure 30 is provided with multiple through hole 31, and pin embeds the exterior edge face of rotating shaft 20 through through hole 31, circular closure 30 and base 10 can be fixed.The diameter of circular closure 30 is identical with disk 11 and be greater than the external diameter of roller bearing 20, and the inner side surface of disk 11 and circular closure 30 forms the draw-in groove with guide rail.In the present embodiment, the cross section of draw-in groove is rectangle, is applicable to the guide rail of square-section.
The inner of rotating shaft 12 is provided with the first boss 14, first boss 14 and offsets with the side of the inner ring of roller bearing 20.The inner side surface of circular closure 30 is provided with fastening protrusion 32 and the second boss 33, and fastening protrusion 32 and the second boss 33 offset with the another side of the exterior edge face of rotating shaft 12, the inner ring of roller bearing 20 respectively, and through hole 31 is arranged on fastening protrusion 32.The thickness of fastening protrusion 32 is greater than the thickness of the second boss 33.
In the present embodiment, the number of roller bearing 20 is two, is arranged side by side.
The utility model is made up of base, roller bearing and capping, structure is simple, easy for installation, roller can be bolted on the position of needs, and base and capping are located at the two ends of roller bearing, makes it keep lengthwise position to fix, the inner side surface of disk and capping forms the draw-in groove with guide rail, simple installation, cost is low, is easy to change during maintenance.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change made under enlightenment of the present utility model, and every have identical or close technological scheme with the utility model, all falls within protection domain of the present utility model.
