Above-mentioned rotor frame 72 forms with the cylindrical structure of opening above, following central authorities form to be provided with and insert the through slot 72a that is through with above-mentioned rotating shaft 80, and periphery is also big for the diameter that forms certain gap ratio said stator 60 between said stator 60 and rotor 70 magnet 74.
Above-mentioned rotor magnet 74 is installed in the inner peripheral surface with the corresponding above-mentioned rotor frame 72 of the outer peripheral face of said stator 60, by forming with the interactional majority of an electromagnetic force magnet (not shown) with said stator 60.
Above-mentioned rotor bushing 90 is by an end that is combined in above-mentioned rotating shaft 80 with spline, and along with periphery form be provided with articulate groove 100 and permeability hole 102a flange 102 towards the lining main body 92 of circumferencial direction projection with for flange 102 cast forms around above-mentioned lining main body 92, and the casting station 94 that is fastened on the above-mentioned rotor frame 72 forms.
Above-mentioned lining main body 92 is as the parts that form with metal material, and interior week is formed with the pipeline configuration that formation is provided with spline, periphery form be provided with the circumferencial direction projection articulate groove 100 and flange 102.
The groove 100 that articulates like this forms offset in the outer circumferential downward direction and the peripheral direction of above-mentioned lining main body 92, causes above-mentioned casting station 94 to articulate the adhesion of guaranteeing above-mentioned lining main body 92 and casting station 94 to the downward direction or the peripheral direction of lining main body 92.
Meanwhile,, the periphery of lining main body 92 is provided with most above-mentioned flanges 102 that stagger with equal angular, the casting hole 102a of infiltration sclerosis casting liquid when the central part of above-mentioned flange 102 forms the cast form that is provided with casting station 94 along with forming.And the permeability hole 102a that so forms forms towards the long distance of the circumferencial direction of lining main body 92.
Above-mentioned casting station 94 is as the mo(u)lding of synthetic resin material, forming around groove 100 and flange 102 castings that articulate of above-mentioned lining main body 92, all form to justify plate structure, each self-forming is provided with the corresponding second connecting hole 94a with the first connecting hole 72b of above-mentioned rotor frame 72 between the above-mentioned flange.
Then, above-mentioned rotor bushing 90 is connected on the first connecting hole 72b and the second connecting hole 94a because of link 96, therefore be installed in above-mentioned rotor frame 72 below, also more can increase the adhesion between above-mentioned lining main body 92 and the casting station 94.
Add that an end spline of above-mentioned rotating shaft 80 is combined on the above-mentioned lining main body 92, and connect the projection bottom, so above-mentioned bottom is fixed on the above-mentioned rotor bushing 90 because of being connected with rotor nut 98 from the downside of above-mentioned lining main body 92.
It is as follows to describe making and the assembling process according to the rotor bushing of motor for washer of the present invention that as above constitute in detail:
At first, the lining main body 92 that formation is provided with above-mentioned flange 102 and articulates groove 100 is arranged in behind the casting gold mould inside to the inside of above-mentioned casting gold mould and injects and the casting liquid of hardening synthetic resin material is finished rotor bushing 90.
At this moment, the casting liquid that is injected into the casting gold mould also can be connected by above-mentioned permeability hole 102a so touch top with the following casting liquid of above-mentioned flange 102 to the permeability hole 102a of above-mentioned flange 102 infiltration.
In addition, the rotor bushing 90 of cast form forms between above-mentioned flange 102 and is provided with the corresponding second connecting hole 94a with the first connecting hole 72b of above-mentioned rotor frame 72.
If produce aforesaid rotor bushing 90, above-mentioned rotor bushing 90 is formed on for the lower end is inserted on the through slot 72a of central authorities of rotor frame 72, therefore combine closely below above-mentioned rotor frame 72, and because of being connected with link 96 on above-mentioned first connecting hole 72b and the above-mentioned second connecting hole 94a, so above-mentioned rotor bushing 90 is fixedly mounted on the rotor frame 72.
The technological innovation of the rotor bushing of the motor for washer of the present invention that above-mentioned structure like this constitutes all has many saving graces for technical staff of the same trade now, and the progressive that possesses skills really.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
