Abstract
The utility model discloses a kind of cast-iron rotor structure of embedded fixing magnet steel, comprise rotor, the two ends in described rotor outer circle face are equipped with annular flange flange, groove is formed between described flange, the width of described groove equals the length of two described magnet steel, on described rotor, described between two magnet steel along the circumferential direction is fixedly separated by screw, and the gradient of described screw and the gradient at described magnet steel interval are consistent.Two magnet steel along rotor axial are fixed along the length direction of magnet steel by groove by the utility model, on rotor, magnet steel between two along the circumferential direction is fixedly separated by screw, the gradient of screw and the gradient at magnet steel interval keep identical, while screw-driving, magnet steel is radially compressed, do not need fixture can realize the assembling of magnet steel yet, structure is simple, be easy to change, interference can not be caused to other physical dimensions of complete machine, can significantly reduce the alinco assembled time, prevent magnet steel from coming off, practical.
Description
Technical field
The utility model relates to a kind of Capstan rotor structure, is specifically related to a kind of cast-iron rotor structure of embedded fixing magnet steel.
Background technology
In permagnetic synchronous motor, in order to obtain maximum magnetic energy product, and facilitate the processing of magnet steel, magnet steel often adopts segmentation structure, two pieces or polylith composition.In rotor surface alinco assembled technique, because segmentation magnet polarities is identical.Cause each point of intersegmental magnet steel mutually to repel vertically, cause alinco assembled difficulty.Conventional solution is with fixture, is fixed vertically by segmentation magnet steel, after waiting for magnet steel glue water condensation, removes fixture.This kind of technique has certain potential safety hazard, and glue very easily produces rotten aging phenomenon due to the relation of time, and cause sticking strength to decline to a great extent, magnet steel comes off vertically.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of cast-iron rotor structure of embedded fixing magnet steel, by groove, two magnet steel along rotor axial are fixed along the length direction of magnet steel, do not need fixture also can realize the installation of magnet steel, practical.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A cast-iron rotor structure for embedded fixing magnet steel, comprises rotor, and the two ends in described rotor outer circle face are equipped with annular flange flange, form groove between described flange, and the width of described groove equals the length of two described magnet steel.
Further, on described rotor, described between two magnet steel along the circumferential direction is fixedly separated by screw, and the gradient of described screw and the gradient at described magnet steel interval are consistent.
The beneficial effects of the utility model are:
Two magnet steel along rotor axial are fixed along the length direction of magnet steel by groove by the utility model, on rotor, magnet steel between two along the circumferential direction is fixedly separated by screw, the gradient of screw and the gradient at magnet steel interval keep identical, while screw-driving, magnet steel is radially compressed, do not need fixture can realize the assembling of magnet steel yet, structure is simple, be easy to change, interference can not be caused to other physical dimensions of complete machine, can significantly reduce the alinco assembled time, prevent magnet steel from coming off, practical.
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.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
