Description
Technical field
The utility model relates to the rolling friction pair that a kind of petroleum industry applies to, specifically the roller support of a kind of rolling friction pair and applying rolling friction pair.
Background technology
At present, roller support is widely used in oil, electric power and steel industry, and rolling friction pair is the important feature of roller support, existing rolling friction pair mainly contains two kinds of versions: one is arrange many cylindrical rollers between the upper and lower base plate of bearing, is realized the rolling of bearing by the rolling of cylindrical roller; Two is arrange multiple groove between the upper and lower base plate of bearing, spin is positioned in groove, is realized the rolling of bearing by the rolling of spin.For the first structure, because cylindrical roller only can roll along a direction, for the pipeline needing multidirectional movement, just cannot use, range of use has limitation, for the second structure, need directly to offer multiple groove on base plate, affect base plate strength, tooling cost is higher, less economical simultaneously.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Summary of the invention
The utility model is the deficiency solving rolling friction pair in prior art, provides a kind of rolling friction pair and uses the roller support of this friction pair.
The technical solution adopted in the utility model provides a kind of rolling friction pair, comprise and be installed on spin stop collar on substrate and can free rolling spin, wherein, described spin stop collar is provided with upper end open, and the inside of described spin stop collar is provided with the internal cavities holding spin; Described spin is sat up straight in the internal cavities of described spin stop collar, and the upper end of spin exceeds described upper end open and exposes for stressed part sphere.
Wherein, the height of described spin stop collar is greater than the radius of described spin, and the upper end open minimum width of described spin stop collar is less than the diameter of described spin.
Wherein, the upper end open of described spin stop collar is circular.
Wherein, described upper end open be dimensioned slightly smaller than the size of spin at the cross-sectional plane of this opening.
A kind of roller support using above-mentioned rolling friction pair, comprise upper plate and lower shoe, wherein, lower shoe is provided with substrate, described substrate is provided with described rolling friction pair, spin stop collar is installed on substrate, and spin stop collar is provided with upper end open, and the inside of described spin stop collar is provided with the internal cavities holding spin; Described spin is sat up straight in the internal cavities of described spin stop collar, and the upper end of spin exceeds described upper end open and is subject to the pressure from upper plate load, and substrate is withstood in the lower end of spin.
Wherein, the height of described spin stop collar is greater than the radius of described spin, and the upper end open minimum width of described spin stop collar is less than the diameter of described spin.
Wherein, the upper end open of described spin stop collar is circular.
Wherein, described upper end open be dimensioned slightly smaller than the size of spin at the cross-sectional plane of this opening.
Compared to the prior art, the utility model is spacing to spin by spin stop collar, and cost is low, can realize rolling in multiple directions, and rolling friction pair can realize modularized production simultaneously, is convenient to enhance productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of rolling friction pair.
Fig. 2 is the structural representation of an embodiment of roller support.
Detailed description of the invention
Now the utility model is further described by reference to the accompanying drawings.
See Fig. 2, what Fig. 2 showed is an embodiment of roller support, roller support comprises upper plate 5 and lower shoe 6, the top of upper plate 5 is connected with conduit saddle 4, rolling friction pair is provided with between upper plate 5 and lower shoe 6, rolling friction pair quantity in the present embodiment is four tools, is arranged at respectively on two pieces of substrates 3.
See Fig. 1, rolling friction pair comprises substrate 3, substrate 3 is provided with spin stop collar 2, and described spin stop collar 2 is provided with upper end open, and the inside of described spin stop collar 2 is provided with the internal cavities holding spin 1; Described spin 1 is sat up straight in the internal cavities of described spin stop collar 2, and the upper end of spin 1 exceeds described upper end open and exposes for stressed part sphere.Height due to spin stop collar 2 is less than the diameter of spin 1, and the top of such spin 1 just can contact with needing the face of rolling, and realizes friction of rolling.
The height of spin stop collar 2 is greater than the radius of described spin 1, and the upper end open minimum width of spin stop collar 2 is less than the diameter of described spin 1, can ensure that spin 1 can not come off from spin stop collar 2 in installation or transportation like this.
The upper end open of spin stop collar 2 is circular, circular open be dimensioned slightly smaller than the size of spin 1 at the cross-sectional plane of this opening.The circular open of spin stop collar 2 can ensure that the gap between opening and spin 1 is minimum, to prevent dust and foreign material from entering, and then affects the service life of roller.
Be the structural representation of an embodiment of rolling friction pair see Fig. 1, Fig. 1, identical with the friction of rolling auxiliary structure in above-described embodiment, technique effect is identical, so place repeats no more.
In other embodiment of the present utility model, can also be out of shape above-mentioned roller support, the height of described spin stop collar can also be less than the radius of spin; The opening minimum width of described spin stop collar can also be greater than the diameter of spin; The opening of described spin stop collar can also be other shape, such as rectangle, and the bond length of rectangle is less than the diameter of spin; Rolling friction pair quantity on described roller support can also be multiple, determines according to actual load.
Above by reference to the accompanying drawings and embodiment describe embodiment of the present utility model; the structure that embodiment provides does not form restriction of the present utility model; in this area, those skilled in the art can adjust according to needs, make various distortion within the scope of the appended claims or revise all in protection domain.
