Abstract
The utility model discloses a permanent magnet suspension mechanical rotor which comprises a rotor core, a bearing, a magnet suspension bearing outer ring and multiple permanent magnets. The multiple permanent magnets are uniformly disposed on the rim of the magnet suspension bearing outer ring. The bearing sleeves on the rotor core and is disposed in the magnet suspension bearing outer ring. Since the permanent magnets are disposed on the outer wall of the magnet suspension bearing outer ring and are fixed by fixing buckles, the permanent magnet suspension mechanical rotor is relatively stable in performance and relatively simple in structure, and has a prolonged service life.
Description
Technical field
The utility model relates to a kind of rotor, relates in particular to a kind of permanent magnetic suspension mechanical rotor.
Background technology
The generally application of pole material as motor or generator by rare earth permanent-magnetic material neodymium iron boron in prior art, but because NdFeB material is more expensive, in order to reduce costs, someone has proposed permanent magnetic material and permeability magnetic material technical scheme spaced apart, its mounting means is the uniform dovetail groove of shading ring inner ring, but this structure is comparatively complicated, and unstable properties in use.
Utility model content
The purpose of this utility model is just to provide in order to address the above problem a kind of permanent magnetic suspension mechanical rotor.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises rotor core, bearing, magnetic suspension shaft bearing outer-ring and permanent magnet, described permanent magnet comprises polylith, evenly be arranged on the edge of described magnetic suspension shaft bearing outer-ring, described bearing holder (housing, cover) is loaded on described rotor core and is arranged in described magnetic suspension shaft bearing outer-ring.
Further, between described magnetic suspension shaft bearing outer-ring and described bearing, be provided with insulating barrier.
Further, described permanent magnet is diamond structure, and its middle part is installed on the outer wall of described magnetic suspension shaft bearing outer-ring by clip.
Further, described permanent magnet comprises four, is evenly arranged on the outer wall of described magnetic suspension shaft bearing outer-ring.
The beneficial effects of the utility model are:
The utility model is by the outer wall at magnetic suspension shaft bearing outer-ring, permanent magnet being set, and fixes by clip, makes performance comparatively stable, and its structure is also fairly simple, and be also improved useful life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of permanent magnetic suspension mechanical rotor described in the utility model.
In figure: 1-rotor core, 2-bearing, 3-insulating barrier, 4-magnetic suspension shaft bearing outer-ring, 5-permanent magnet, 6-clip.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises rotor core 1, bearing 2, magnetic suspension shaft bearing outer-ring 4 and permanent magnet 5, permanent magnet 5 comprises four, evenly be arranged on the edge of magnetic suspension shaft bearing outer-ring 4, bearing 2 is set on rotor core 1 and is arranged in magnetic suspension shaft bearing outer-ring 4, between magnetic suspension shaft bearing outer-ring 4 and bearing 2, be provided with insulating barrier 3, permanent magnet 5 is diamond structure, and its middle part is installed on the outer wall of magnetic suspension shaft bearing outer-ring 4 by clip 6.
Those skilled in the art do not depart from essence of the present utility model and spirit, can there is various deformation scheme to realize the utility model, the foregoing is only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, within being all contained in interest field of the present utility model.
