Abstract
The invention discloses a fixing structure for a stator core and a machine base. The fixing structure comprises a locating rib and supporting blocks, wherein the locating rib is fixed between the stator core and the machine base; the supporting blocks comprise the multiple supporting blocks A for fixing the locating rib in the radial direction and the multiple supporting blocks B for fixing the locating rib in the tangential direction, and elastic elements are arranged between the supporting blocks A and the locating rib. The fixing structure can effectively protect the stator core and the machine base against buckling deformation caused by swelling of the stator core and can also reduce vibration of the stator core through rigidity of the machine base.
Description
Technical field
The invention belongs to machine field, relate in particular to the fixed structure of a kind of stator core and support.
Background technology
In prior art, fixing of motor stator core and support, is to be connected with tray by positioning bar substantially.As China Patent No. " 200910073282.7 " discloses the two irremovable positioning bar assembling and welding process of dove tail of a kind of hydraulic generator, its open day is on June 30th, 2010.In this patent, the syndeton of stator core and support is: positioning bar is weldingly fixed on stator core, and tray is weldingly fixed on support, and the dove tail of positioning bar is weldingly fixed in the dovetail slot of tray.But in actual use, in the time of unit operation, stator core expands (radially) because being heated, but the dilation of support is far smaller than the dilation of stator core, this just makes to have occurred larger stress between stator core and out frame, and this stress may cause the buckling deformation of stator core and support.
In addition, the problems referred to above are solved in the certain air gap that radially reserves having proposed in prior art between positioning bar and tray, although this mode can solve the problem that stator core and stand stiffness fixedly cause buckling deformation, but due to existence and the footpath degree of freedom upwards in gap, cause stator core not utilize well the rigidity of support, and then may cause the vibration of stator core to increase.
Summary of the invention
The object of the invention is to overcome the above-mentioned problems in the prior art, the fixed structure of a kind of stator core and support is provided.The present invention not only can effectively prevent from, because of stator core the expand stator core and the support buckling deformation that cause, can also utilizing the rigidity of support to reduce the vibration of stator core.
For achieving the above object, the technical solution used in the present invention is as follows:
The fixed structure of a kind of stator core and support, comprise the positioning bar and the tray that are fixed between stator core and support, it is characterized in that: described tray comprises multiple tray A for stationary positioned muscle radially and multiple tray B for tangential stationary positioned muscle, between described tray A and positioning bar, is provided with flexible member.
On described tray A, offer mounting groove, described tray A is connected with positioning bar by mounting groove, and described flexible member is fixed in mounting groove.
Described flexible member is dish spring, spring or corrugated plating.
Described tray A and tray B are spaced.
Employing the invention has the advantages that:
One, in the present invention, because support itself and stator core itself all have rigidity, therefore in the time that stator core heating is expanded, by being arranged on the flexible member between tray A and positioning bar, make stator core on support, have certain radial expansion space, can efficient solution determinant iron core cause the problem of stator core and support buckling deformation, the useful life that is conducive to improve stator core because of expansion.And, also make stator core can utilize to a certain extent the rigidity of support by flexible member, make support can retrain better stator core, reduce the vibration of stator core, make the operation of motor more safe and reliable.Again because tray B can be from tangential stationary positioned muscle, therefore by the cooperation of tray A and tray B, can be from stationary positioned muscle radially and tangentially, the steadiness that had both made to install rear stator core is better, can prevent again stator core and support buckling deformation.
Two, in the present invention, described tray A is connected with positioning bar by mounting groove, and described flexible member is fixed in mounting groove, and this structure makes support better to the binding effect of stator core.
Three, in the present invention, described flexible member can be made up of common materials such as dish spring, spring or corrugated platings, makes the present invention under the prerequisite of cost less cost, problem that just can the buckling deformation of efficient solution determinant iron core.
Four, in the present invention, described tray A and tray B are spaced, and this structure is enough not only from stationary positioned muscle radially and tangential, and the steadiness that also makes to install rear stator core is better.
