Abstract
The utility model relates to a magnetic suspension bearing with permanent magnetism, which is composed of an inner ring assembly and an outer ring assembly, wherein the inner ring assembly is a cylinder-shaped body, the outer diameters of both end parts of the cylinder-shaped body are small, the outer diameter of the middle part of the cylinder-shaped body is big, the outer ring assembly is a cylinder-shaped boy, the outer diameters of both end parts of the cylinder-shaped body are small, and the outer diameter of the middle part of the cylinder-shaped body is big. The outer ring assembly is wrapped and sheathed on the inner ring assembly without contact. The inner ring assembly is composed of an inner ring, a left magnetic loop of the inner ring, a right magnetic loop of the inner ring and a middle magnetic loop of the inner ring. The outer ring assembly is composed of an outer ring, a left magnetic loop of the outer ring, a right magnetic loop of the outer ring and a middle magnetic loop of the outer ring. The utility model has the advantages of no abrasion, high transmission efficiency, no cooling need, no lubricating need and long service life.
Description
Technical field
The utility model relates to a kind of bearing.
Background technique
At present, at the employed bearing of mechanical industry, all constitute by bearing inner race, outer ring and intervenient rolling element, it all produces friction in transmission, wear and tear between the driving component, for reducing wear, need cooling and lubricated, it is low that this class bearing has a transmission efficiency, and wearing and tearing are big, the shortcoming that working life is short.
Summary of the invention
The purpose of this utility model provides a kind of nothing wearing and tearing, transmission efficiency height, need not cooling and lubricated, long service life, and no rolling element is by the permanent magnetism magnetic suspension bearing of magnetic levitation between Internal and external cycle.
Technical solution of the present utility model is: it is made of inner ring assembly and outer ring assembly, the inner ring assembly is the big cylinder-like body of the little middle part of two end part external diameter external diameter, the outer ring assembly is the big cylinder-like body of the little middle part of two end part internal diameter internal diameter, and the outer ring assembly does not contact and fits on the inner ring assembly; The inner ring assembly is made of inner ring, inner ring left side magnet ring, the right magnet ring of inner ring and inner ring middle magnetic ring, inner ring is the big cylinder-like body of the little middle part of two end part external diameter external diameter, the two ends at the position that the external diameter that the right magnet ring of inner ring left side magnet ring and inner ring is separately fixed at inner ring is big, inner ring middle magnetic ring are enclosed within on the outer tube wall at the big position of the external diameter of inner ring; The outer ring assembly is made of outer ring, a left side, outer ring magnet ring, the right magnet ring in outer ring and outer ring middle magnetic ring, the outer ring is the big cylinder-like body of the little middle part of two end part internal diameter internal diameter that main circle and the end cap by mutual flexible connection constitutes, and a left side, outer ring magnet ring, the right magnet ring in outer ring and outer ring middle magnetic ring are separately fixed on the outer ring inwall with inner ring left side magnet ring, inner ring right side magnet ring and the corresponding position of inner ring middle magnetic ring.
Inner ring left side magnet ring, the right magnet ring of inner ring, inner ring middle magnetic ring, a left side, outer ring magnet ring, the right magnet ring in outer ring and outer ring middle magnetic ring are permanent magnet, and other parts are made by non-magnet material.Utilize the characteristic of magnet, homopolar-repulsion makes the inner ring assembly not contact mutually with the outer ring assembly, is in state of suspension.
Technique effect of the present utility model is: it has does not have wearing and tearing, transmission efficiency height, need not cooling and lubricated, the advantage of long service life.
