Description
Technical field
The utility model relates to a kind of bearing bearing assembly, and the utility model especially relates to the external selfaligning bearing bearing assembly of a kind of angular travel valve self-adapting type, and the utility model belongs to control valve for fluids technical field.
Background technique
At present, lining is mostly adopted to lead in domestic existing angular travel valve bearing unit form, its lining is arranged on valve inner, lining endoporus coordinates with valve rod outer round surface, protects stem surface, carries out circumference guiding to the rotary motion of valve rod simultaneously, the surface hardness of lining is less than valve rod, as long as when more resleeve after generation wearing and tearing, and do not need to change valve rod or valve body, thus the cost depletions of reduction product; But there are some defects in actual use in this structural type.First lining is arranged on valve inner, lining coordinates for Spielpassung with valve rod, when being applied to high temperature or dust operating mode, the cooperation meeting Yin Gaowen generating material dilatancy of valve rod and lining or dust block and cause valve rod to occur jam phenomenon, secondly lining only carries out circumference guiding, does not have to bend with valve rod slight deformation and the function of self-aligning; These problems can cause valve normally to work, thus affect the reliability of whole pipe-line system, cause economic loss even to cause security incident.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provide a kind of can expand valve applications operating mode scope, extend valve working life, guarantee valve doors and door fittings safe operation thus the external selfaligning bearing bearing assembly of the self-adapting type of enhancing productivity.
According to the technological scheme that the utility model provides, the external selfaligning bearing bearing assembly of described self-adapting type, comprises valve rod, bearing cap, selfaligning roller bearing, spacer, bearing support and valve body; Valve rod is rotatablely equipped with in valve body, valve body is fixed with bearing support, bearing support is fixed with bearing cap, selfaligning roller bearing is provided with in bearing cap, the cylindrical of valve rod coordinates with the inner ring body of selfaligning roller bearing, the valve rod of bearing cap and bearing support binding site is provided with between outer land terrace, this between outer land terrace is provided with spacer, inner ring body one end face of described selfaligning roller bearing contacts with spacer, outer ring body one end face of selfaligning roller bearing contacts with bearing cap, and the outer ring body other end of selfaligning roller bearing contacts with bearing support.
Described selfaligning roller bearing is biserial rolling body type selfaligning roller bearing.
Described bearing support is provided with locating recesses, in this locating recesses, described bearing cap is installed.
Compared with the prior art the utility model has the following advantages:
1, the selfaligning roller bearing in the utility model has two row spherical rolling bodies, and the frictional force produced during rotation is little, can reduce valve and run moment of torsion;
2, in the utility model, the inner ring body of selfaligning roller bearing and valve rod face are close to does not have relative movement, and valve rod outer round surface and brearing bore face do not exist wearing and tearing;
3, in the utility model, selfaligning roller bearing possesses the function of self-aligning when valve rod generation slight bending, can bear larger radial load and certain thrust load;
4, the utility model is arranged on valve body head plate, when being applied to the operating mode of high temperature or dust medium, will, because of material temperature distortion and valve rod jam, cause valve to open normally or to close.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of part A in Fig. 1.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
The external selfaligning bearing bearing assembly of this self-adapting type, comprises valve rod 1, bearing cap 5, selfaligning roller bearing 6, spacer 7, bearing support 8 and valve body 11, valve rod 1 is rotatablely equipped with in valve body 11, valve body 11 is fixed with bearing support 8, bearing support 8 is fixed with bearing cap 5, selfaligning roller bearing 6 is provided with in bearing cap 5, the cylindrical of valve rod 1 coordinates with the inner ring body of selfaligning roller bearing 6, bearing cap 5 with the valve rod 1 of bearing support 8 binding site are provided with between outer land terrace, this between outer land terrace is provided with spacer 7, inner ring body one end face of described selfaligning roller bearing 6 contacts with spacer 7, outer ring body one end face of selfaligning roller bearing 6 contacts with bearing cap 5, the outer ring body other end of selfaligning roller bearing 6 contacts with bearing support 8.
Described selfaligning roller bearing 6 is biserial rolling body type selfaligning roller bearing.
Described bearing support 8 is provided with locating recesses, described bearing cap 5 is installed in this locating recesses.
During installation, bearing support 8 to be fixed in valve body 11 on head plate through valve rod 1 second hex head bolt 9 and the second flat gasket 10, spacer 7 is first placed on the between outer land terrace of valve rod 1, then selfaligning roller bearing 6 is installed in bearing cap 5, the inner ring body of selfaligning roller bearing 6 coordinates with valve rod 1 periphery, bearing cap 5 first hex head bolt 2 of selfaligning roller bearing 6 will be housed again, first flat gasket 3 and the first hex-head nut 4 are arranged in the locating recesses of bearing support 8, now, first hexagon nut 4 is not tightened, valve rod 1 adjust to corresponding stretch out height (play phenomenon can not be had) after, observe bearing cap 5 simultaneously and between bearing support 8, coordinate whether have gap, repair spacer 7 is needed if any gap, spacer 7 repair makes the locating recesses face of bearing cap 5 plane and bearing support 8 fit completely to corresponding size, tighten fixing by the first hex-head nut 4 again.
Working principle of the present utility model is as follows:
The utility model is coordinated with valve rod 1 by the selfaligning roller bearing 6 be arranged in bearing cap 5, aligning when final controlling element torsional interaction center downward regulating roller bearing 6 pairs of valve rods 1 realize guiding and slight bending, bearing cap 5 is arranged on bearing support 8 simultaneously, bearing support 8 is connected with valve body 11, whole assembly is arranged on valve body outside, facilitates installing/dismounting.
