Abstract

The utility model is an outer sleeve of a magnet of a medium-high speed AC servo motor rotor. The outer sleeve is an annular wrapping layer, which wraps the magnet of the servo motor rotor closely. The sleeve is made from non-permeable metal materials, carbon fiber tubes, belt-shaped or line-shaped entanglements, engineering plastics, or temperature-resistant and thermal shrinkable sleeve tubes. The outer sleeve made from each material is provided with the particular nature.

Description

In, the overcoat of high speed AC servo motor rotor magnetic
Technical field
The utility model relates to a kind of rotor overcoat, especially relate to a kind of in, the overcoat of high speed AC servo motor rotor magnetic.
Background technology
At present; both at home and abroad in the AC servo motor; high-revolving application conditions is very extensive; in order to prevent that magnetic material on the rotor magnetic is in rotor; during high the rotation, owing to action of centrifugal force comes off, in order to guarantee the operate as normal of alternating-current permanent-magnet servo motor; especially crucial is that rotor magnetic parts are complete, and the rotor magnetic is protected, reinforced is very important.
Summary of the invention
The utility model mainly is to solve to reinforce technical problem not firm, that come off easily between existing in prior technology magnetic and the rotor core; can protect, reinforce magnetic and provide a kind of; and assembling is simple, cost is low, the overcoat of high speed AC servo motor rotor magnetic.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: provide a kind of in, the overcoat of high speed AC servo motor rotor magnetic, this overcoat is an annular integument, closely be wrapped in the servo motor rotor magnetic outside, its special feature be described in, the material of the overcoat of high speed AC servo motor rotor magnetic is non-magnetic conductive metal material, perhaps carbon fiber pipe, perhaps be with, the wire twister, perhaps engineering plastics, perhaps heatproof heat-shrinkable T bush, described magnetic is the magnetic that is fixed in the annular groove of the rotor core outside, the thickness of magnetic is more than or equal to the degree of depth of annular groove, and the two ends of overcoat fit tightly on the rotor core at annular groove two ends.The main effect of overcoat is the magnetic on protection, the reinforcing rotor core; because action of centrifugal force; and the problem such as fixing incomplete between magnetic and the rotor core, magnetic in may break away from rotor under the high-revolving situation, and the overcoat that provides can effectively prevent this coming off.Wherein, non-magnetic conductive metal material, material such as stainless steel for example, can make permanent magnet in the overcoat of this material, magnetic loss can not take place, prolong the useful life of magnetic, carbon fiber pipe then has very high intensity and toughness, under the impact of very big external force, can not break, and band, the wire twister can closely be wrapped in rotor exterior and can not cause magnet steel to come off, and the heat-shrinkable T bush of engineering plastics and heatproof can shrink when being heated, can be wrapped in the outside of rotor closely, utilize the characteristic of the tensile strength of material self, offset magnetic material on the rotor in centrifugal force under the high rotating speed, prevent that magnetic material breaks away from rotor.
As preferably, described non-magnetic conductive metal material adopts body of stainless steel.Body of stainless steel is a kind of common non-magnetic conductive metal material, and it has characteristics such as intensity is big, cost is low, has widely used value.
Therefore, the utlity model has rational in infrastructure, manufacturing process is simple, cost is low, characteristics such as wide accommodation especially can be by the material of the plurality of optional material as overcoat, and the overcoat that each material constituted all has its special nature, it is big to have intensity as the overcoat of body of stainless steel, the speciality of not loss magnetic; Then have very high intensity and toughness as carbon fiber pipe, under the impact of very big external force, can not break; As band, the wire twister can closely be wrapped in the advantage that rotor has simple operations; And the heat-shrinkable T bush of engineering plastics and heatproof can shrink when being heated, and can be wrapped in the outside of rotor closely, has one-shot forming, is firm characteristics.
Description of drawings
Accompanying drawing 1 is a kind of structure schematic diagram of rotor before the utility model overcoat is installed;
Accompanying drawing 2 is a kind of structure schematic diagrames that the utility model overcoat is installed the back rotor;
Accompanying drawing 3 is a kind of main TV structure schematic diagrames of the present utility model;
Accompanying drawing 4 is B of accompanying drawing 3---B cutaway view schematic diagram;
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of structure schematic diagram of rotor before overcoat is installed, the magnetic 1 of fixing some specific arrangement in the intimate outside of rotor, the magnetic outside is with overcoat 2, this overcoat can be by non-magnetic conductive metal material, perhaps carbon fiber pipe, perhaps band, wire twister, perhaps engineering plastics, perhaps the heatproof heat-shrinkable T bush constitutes, and overcoat is made by carbon fiber pipe in the present embodiment.Magnetic mainly is installed in the annular groove 4 of rotor core 3, and the two ends of overcoat fit tightly on the rotor core at annular groove two ends, and employed carbon fiber pipe then has very high intensity and toughness.
In assembling process, at first the rotor overcoat is cut to the identical length of rotor, and two plane parallel.To post magnetic then, cylindrical is cleaned out through the rotor of overground processing, coats lubricant.Rotor is lain against on the press, with the rotor overcoat by last under gland in rotor exterior, just finished the assembling of overcoat.

Claims (2)

1. in one kind, the overcoat of high speed AC servo motor rotor magnetic, this overcoat (2) is an annular integument, closely be wrapped in servo motor rotor magnetic (1) outside, it is characterized in that: in described, the material of the overcoat of high speed AC servo motor rotor magnetic is non-magnetic conductive metal material, perhaps carbon fiber pipe, perhaps be with, the wire twister, perhaps engineering plastics, perhaps heatproof heat-shrinkable T bush, described magnetic is fixed in rotor core (3) outside annular groove (4), the thickness of magnetic is more than or equal to the degree of depth of annular groove, and the overcoat interference is fitted in the magnetic surface.
2. in according to claim 1, the overcoat of high speed AC servo motor rotor magnetic is characterized in that, described non-magnetic conductive metal material adopts body of stainless steel.
