Abstract
The utility model discloses an accurate rotatory alternately magnetic suspension bearing in outer lane, it comprises first inner circle, second inner circle, outer lane, first inner circle, second inner circle form the big recess of end osculum to closing, the outer lane be provided with with the boss that the groove phase corresponds, the boss with the recess to all installing mated hollow cone magnetic ring on the inclined plane that closes, the face that corresponds of hollow cone magnetic ring is homopolar in the hollow cone magnetic ring in pairs. The utility model discloses the face that corresponds of hollow cone magnetic ring is homopolar in the hollow cone magnetic ring in pairs, and magnet homopolarity repulsion realizes that first inner circle and second inner circle are fixed, the outer lane suspension. This intersection magnetic suspension bearing does not have the rolling element, does not need emollient pollution -free, has reduced the maintenance cost, and non -contact during owing to the rotation has greatly improved bearing rotation speed, and the outer lane is indivisible overall structure simultaneously, has guaranteed the running accuracy of outer lane.
Description
Technical field
The utility model belongs to technical field of bearings, especially a kind of outer ring precision rotation intersection magnetic suspension bearing.
Background technology
In prior art, the bearing that intersects has two kinds, and one is crossed cylindrical roller bearing, and another kind is crossed-circle taper roller bearing.But both bearings broadly fall into a lasso and rotarily drive the rolling bearing that rolling element rotates, due to rolling element and inside and outside Race Line Contact, frictional resistance is big, and rotating speed is low, and these two kinds of bearings need lubricant in the running simultaneously, and maintenance cost is higher and has pollution.Chinese patent ZL01520409674.7 discloses a kind of magnetic suspension bearing that intersects, this bearing is made up of outer ring and an overall inner ring of two segmentations, this bearing is applicable to the operating mode that inner ring running accuracy is higher, for outer ring running accuracy being required the position of higher precision machinery human arm, this bearing is made up of the two parts separated due to outer ring, it is impossible to meet the demand of this operating mode.
Utility model content
The purpose of this utility model is just to provide a kind of outer ring precision rotation intersection magnetic suspension bearing, and this intersection magnetic suspension bearing is without rolling element, and maintenance cost is low, and rotating speed is high, and outer ring running accuracy is high simultaneously.
The utility model is achieved in that
Outer ring precision rotation intersection magnetic suspension bearing, is made up of the first inner ring, the second inner ring, outer ring, and described first inner ring, the second inner ring are combined to form the groove that end osculum is big；Described outer ring is provided with the boss corresponding with described groove, and the inclined-plane that described boss is involutory with described groove is mounted on paired hollow cone magnet ring, and the corresponding surface of described paired hollow cone magnet ring hollow core cone magnet ring is homopolarity.
Described first inner ring, the second inner ring are provided with some uniform through holes for cross-under connecting bolt.
The corresponding surface of the utility model paired hollow cone magnet ring hollow core cone magnet ring is homopolarity, magnet homopolar-repulsion, it is achieved the first inner ring and the second inner ring are fixed, outer ring suspends.This intersection magnetic suspension bearing is without rolling element, it is not necessary to lubricant is pollution-free, reduces maintenance cost, noncontact during owing to rotating, and greatly improves bearing rotating speed, and outer ring is indivisible overall structure simultaneously, it is ensured that the running accuracy of outer ring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Shown in Fig. 1, precision rotation intersection magnetic suspension bearing in outer ring is made up of first inner ring the 4, second inner ring 7, outer ring 1, and first inner ring the 4, second inner ring 7 is combined to form the groove that end osculum is big.Outer ring is provided with the boss corresponding with described groove, and the inclined-plane that described boss is involutory with described groove is mounted on paired hollow cone magnet ring, and the material of paired hollow cone magnet ring hollow core cone magnet ring is magnet.
The corresponding surface of the first hollow cone magnet ring 2 and the second hollow cone magnet ring 3 is homopolarity, constitutes paired hollow cone magnet ring.The corresponding surface of the 3rd hollow cone magnet ring 8 and the 4th hollow cone magnet ring 9 is homopolarity, constitutes paired hollow cone magnet ring.First hollow cone magnet ring 2 is identical with the tapering of the inside and outside taper surface of the second hollow cone magnet ring 3, and the 3rd hollow cone magnet ring 8 is identical with the tapering of the inside and outside taper surface of the 4th hollow cone magnet ring 9.
Arrange upper and lower two to being much of inner conical face, lower inner conical face, on this, the tapering in inner conical face and the 4th hollow cone magnet ring 9 male-tapered face are consistent, for installing the 4th hollow cone magnet ring 9 in endoporus direction, outer ring 1.The tapering in this lower inner conical face and the first hollow cone magnet ring 2 male-tapered face are consistent, for installing the first hollow cone magnet ring 2.
First inner ring is provided with a lower male-tapered face, and the tapering in this lower male-tapered face and the second hollow cone magnet ring 3 inner conical face are consistent, and this lower male-tapered face is for installing the second hollow cone magnet ring 3.The axial large end face of the first inner ring is provided with several uniform stepped throughhole.
Second inner ring is provided with a upper male-tapered face, and on this, tapering and the 3rd hollow cone magnet ring 8 inner conical face in male-tapered face are consistent, and on this, male-tapered face is for installing the 3rd hollow cone magnet ring 8.The axial large end face of the second inner ring is provided with several uniform stepped throughhole.The central diameter of the stepped throughhole that the central diameter of the stepped throughhole that the axial large end face of the second inner ring is arranged is arranged equal to the axial large end face of the first inner ring, the end diameter of the second inner ring ladder hole is equal to the end diameter of the first inner ring ladder hole, and the number that arranges of the second inner ring ladder hole arranges number equal to the first inner ring ladder hole.It is connected to the screw bolt and nut of aforementioned through-hole by several the first hollow cone magnet ring 2 and the outer ring 1 of the 4th hollow cone magnet ring 9 to be installed, the first inner ring 4 of the second hollow cone magnet ring 3 is installed and the second inner ring 7 of the 3rd hollow cone magnet ring 8 is installed connects into an entirety.
