Further, the upper surface of described seat ring is provided with the first restraining groove of annular between lug, nib, and described first ball rolls on the upper surface of described first restraining groove and lug, nib.
Further, the upper surface of described lug, nib is provided with the second restraining groove that cross section is cambered surface, and the height of described second restraining groove is higher than described first restraining groove, and described first ball rolls on described first restraining groove and the second restraining groove.
Further, the bottom of described blowout patche is provided with at least 4 containing grooves, and described return unit is spring, and described spring is arranged in described containing groove.
Further, the bottom surface of described sealing cover is provided with the groove for placing the second ball, and described second ball relatively rotates in described groove.
Further, described sealing cover is installed on described case.
By such scheme, the utility model at least has the following advantages: locating effect better and there will not be fault.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model thrust-bearing.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1, a kind of thrust-bearing of the utility model one preferred embodiment, comprise blowout patche 1, seat ring 2, main support 3, rolling element 4 and case 5, rolling element 4 is arranged in main support 3 and rolling element 4 can rollably be arranged between blowout patche 1 and seat ring 2, and case 5 is wrapped in blowout patche 1 with on the outer circumferential face of seat ring 2; The upper surface of seat ring 2 be arranged at intervals with the lug, nib 6 of arc surface and lug, nib 6 with radially direct, the bottom of blowout patche 1 is provided with positioning device, positioning device comprise be arranged on return unit 7 bottom blowout patche, with the auxiliary support 8 be connected bottom return unit 7 and the first ball 9 be arranged in auxiliary support, relatively rolling in the top of the first ball 9 in auxiliary support 8, rolls between lug, nib 6 relatively at the upper surface of seat ring 2 in the bottom of the first ball 9; The upper surface of blowout patche 1 is provided with the rolling groove 10 of annular, and the end face of case 5 is provided with annular opening and on opening, is provided with the sealing cover 11 of annular, and the bottom surface of sealing cover 11 is provided with the second ball 12, second ball 12 relative sliding in rolling groove 10.
Working principle of the present utility model is as follows: blowout patche is under the rolling action of rolling element, relatively rotate with seat ring, rotation between two objects that realization is fixed thereon, as door, window and ground, between the walls, blowout patche relatively rotates with sealing cover under the effect of the second ball, achieve the sealing of sealing cover to bearing rotary position, prevent entering of dust; The first ball on auxiliary support is consistent with the relative position of lug, nib on the whole, when blowout patche rotates, when ball runs into lug, nib, on ball, the auxiliary support in top makes it rise, ball is crossed lug, nib and is entered interstitial site between next adjacent lug, nib, and then achieves location; Because the first ball is limited in auxiliary support, and achieve the synchronous lifting of all first balls, locating effect number, and can prevent ball from dislocating, reduce rate of fault.
In order to limit the scrolling position of the first ball, thrust-bearing of the present utility model, the first restraining groove 13, first ball 9 that the upper surface of seat ring 2 is provided with annular between lug, nib rolls on the upper surface of the first restraining groove 13 and lug, nib 6.It is that the height of the second restraining groove 14, second restraining groove 14 of cambered surface rolls on the first restraining groove 13 and the second restraining groove 14 higher than the first restraining groove 13, first ball 9 that the upper surface of lug, nib 6 is provided with cross section.
Thrust-bearing of the present utility model, the bottom of blowout patche 1 is provided with at least 4 containing grooves 15, and return unit is spring, and spring is arranged in containing groove 15.
Thrust-bearing of the present utility model, groove 16, second ball 12 that the bottom surface of sealing cover 11 is provided with for placing the second ball 12 relatively rotates in groove.
Thrust-bearing of the present utility model, sealing cover 11 is installed on case 5.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
