Embodiment
Specify the present invention below in conjunction with drawings and Examples.
Fig. 3 is the single phase induction motor profile that is equipped with support according to an embodiment of the invention, and Fig. 4 is that the 1st support of Fig. 3 enlarges side view, and Fig. 5 is the 1st support side view of Fig. 4.For convenient in the description of drawings, use identical symbol here, for the position identical with said structure.
As shown in the figure, the single phase induction motor of outfit support of the present invention includes stator 10, rotor 20 and the 1st support 50.Wherein, stator 10 includes stator core 11 and the main coil of each comfortable stator core 11 coiling and stator coil 15 compositions that secondary coil constitutes that are formed with accepting hole 14 in inside; The inside that rotor 20 is installed in accepting hole 14 is the center rotation with the rotating shaft 22 to the prolongation of the both sides of stator core 11; The whole side that forms and be combined in stator 10 of the 1st support 50 usefulness synthetic resin members, include the shaft supporting part 51a that stator core 11 distance to a declared goal of being separated by also rotatably support above-mentioned rotating shaft 22, prolong from above-mentioned shaft supporting part 51a and to form and catch up with to state stator core 11 contacts and be separated by most that distance to a declared goal installs and support footpath 51b along the peripheral direction of shaft supporting part 51a, calcaneus branches support footpath 51b integral body forms and starts the back in order to specify starting point to be turned round by main coil at rotor 20, and the starting switch 51c of cut-out secondary coil power supply forms.
The stacked formation of insulating of stator core 11 usefulness steel current conducting plates, above-mentioned steel current conducting plate is formed with accepting hole 14 in order to accommodate rotor 20 in inside.Be wound with the stator coil 15 that main coil and secondary coil constitute in the stator core 11.
In addition, for rotating shaft 22 rotatably being supported on the both sides of stator core 11, the 1st support 50 and the 2nd support 60 are to the stacked direction combination separately of stator core 11.Here, the 1st support 50 and the 2nd support 60 are made of the synthetic resin members that forms by methods such as injection mouldings.Form promising secure component accepting hole 16 of accommodating on each angle of stator core 11 in conjunction with secure component 58a, and above-mentioned secure component 58a, 58b is combined as a whole the 1st support 50 and the 2nd support 60.Rotor 20 is rotatably installed in inside in stator core 11, and rotor 20 is center rotation with rotating shaft 22, and rotating shaft 22 has long length at the stacked direction of stator core 11.
The centrifugal switch 70 that on a side, can rotate together in the axial combination of rotating shaft 22, and centrifugal switch 70 utilizes operated by centrifugal force starting switch 51c when rotor 20 rotations.
In addition, the 1st support 50 and the 2nd support 60 have shaft supporting part 51a separately, 61a and most support footpath 51b, 61b.Wherein, above-mentioned shaft supporting part 51a, 61a is supporting rotating shaft 22 rotatably; Above-mentioned majority supports footpath 51b, and 61b is from shaft supporting part 51a, and 61a is to rotating shaft 22 extending transversely designated length, its end bent and with stator core 11 contacts, and along shaft supporting part 51a, the peripheral direction of the 61a distance to a declared goal of being separated by separately.Shaft supporting part 51a, 61a is last in conjunction with bearing 57, and above-mentioned bearing 57 supporting rotating shafts 22 make rotating shaft 22 rotations.And, support footpath 51b, be formed with secure component combined hole (53,63) on each end of 61b with secure component accepting hole 16 mutual UNICOMs.
On the 1st support 50 adjoin each other two support to be had between the 51b of footpath and supports the starting switch 51c that footpath 51b forms one, and the side that working beam [Lever] 54 is installed in rotation on starting switch 51c with sliding fast 71b contact or separately.The opposite side of starting switch 51c has the earth terminal 55 that contacts with the end of supporting footpath 51b, and above-mentioned through hole 56 of conductivity secure component 58a process and perforation support footpath 51b in order to make bolt or screw form, 61b and stator core 11 back combinations are formed with through hole 56 at earth terminal 55.Here, the secure component 58a that combines with earth terminal 55 should form bolt or screw form, and with support footpath 51b, the secure component 58b of 61b opposite side combination should form the rivet form.But above-mentioned secure component also can all form the rivet form, perhaps all by bolt or screw morphosis.
According to said structure, rotating shaft 22 inserts 57 li on the bearing of shaft supporting part 61a from the support of the 2nd support 60 footpath 61b side, combines with rotor 20.Then, stator 10 is installed in the periphery of rotor 20, makes each of each angular contact the 2nd support 60 of stator 10 support footpath 61b, and make the 1st support 50 each support footpath 51b contact each corner portions at stator 10.
Thus, the sliding fast 71b of work working face 54 contacts of starting switch 51c becomes the state of turn-on power in main coil and secondary coil separately, and the bearing 57 of opposite side is combined in the shaft supporting part 51a of the 1st support 50.Then, earth terminal 55 contacts behind the end of corresponding support footpath 51b, are supported footpath 51b, the secure component combined hole 53,63 of 61b end and the secure component accepting hole of stator core 11 16 consistent alignment to each.
At this moment, because the support of earth terminal 55 combinations footpath 51b, be formed with nut [Nut] 59 on the 61b with earth terminal 55 contacts, so if nut is connected and fixed the secure component 58a of bolt form and other support footpath 51b for 59 li, the secure component 58b of the last binding rivet form of 61b, the assembling of single phase induction motor was both finished.
