Reference character 250 expression oiliers in the accompanying drawing of not specified (NS).
The assembling process that hereinafter description is had the rotary compressor of this structure.
At first, with reference to Fig. 7, the framework 510 of second bearing 500 is placed on the framework assembly department 621 of anchor clamps 600.At this, the frame fixation unit 624 that is formed by the collet chuck parts radially is unfolded to firmly fix the interior perimeter surface of framework 510.
With reference to Fig. 8, stator 210 is placed in the stator assembly department 622 of anchor clamps 600.At this, the fixed salient 511 of framework 510 is placed on the framework assembly department 621 and is supported, and the coil 240 that is wrapped on the stator 210 is inserted in the stator assembly department 622.
With reference to Fig. 9, its internal diameter is pushed down on anchor clamps 600 because of the chassis body 110 that the heat of specified temp expands to some extent, so that be inserted in the casing assembly department 623.At this, drawn (promptly between a plurality of fixed salients 511 of framework 510 from coil 240 extended lead-in wires 241, lead-in wire is drawn in the groove 627 by the lead-in wire that the opening that is formed by straight line surfaces is inserted into casing assembly department 623) state under, chassis body 110 is inserted.Therefore, 241 problems of being removed the peel because of wearing and tearing (being chafed) of can avoiding going between.
Then, housing 520 is connected to framework 510.The rotor 220 that connects with crankshaft 230, press part 300 and clutch shaft bearing 400 are in a side of stator 210 (promptly, a side relative with second bearing 500) be inserted into, the upper bearing (metal) 410 with clutch shaft bearing 400 is welded to chassis body 110 to be fixed to chassis body subsequently.Lower cover 130 is fixed to second opening 112 of chassis body 110 with sealing chassis body 110.

In the rotary compressor that assembles, when with power supply to the stator 210 of motor 200 so that during rotor 220 rotations, crankshaft 230 rotates with the two end part of this crankshaft, described two end part are supported by the clutch shaft bearing 400 and second bearing 500.Thus, crankshaft 230 is delivered to press part 300 with the rotating force of motor 200.The rotating piston 320 of press part 300 is motion prejudicially in compression volume.Therefore, the 330 pairs of refrigeration agents of blade that form compression volume with rotating piston 320 compress, and thus these compressed refrigeration agents are discharged in the inner space 101 of sealing casing 100.
At this, crankshaft 230 fast rotational, thus the oil that the feasible oilier 250 that is arranged in crankshaft 230 belows can comprise the oil storage portion of sealing casing 100 aspirates.So oil is drawn with lubricated each bearing surface via the oil circuit 233 of crankshaft 230.
So stator can be assembled into the sealing casing by the shrink-fit process quilt simultaneously with second bearing that is installed in the stator upside.Therefore, can be convenient to the assembling of second bearing, reduce cost for manufacturing compressor thus.
Simultaneously, although not shown,, even when a plurality of press part longitudinally is installed, also can in scope same as the previously described embodiments, implement such structure, promptly utilize anchor clamps with stator and second bearing simultaneously shrink-fit to the sealing casing.And thus obtained operating effect is similar to the aforementioned embodiment, so no longer describe in detail.
Previous embodiment and advantage only are exemplary, and should not be construed as limitation of the present invention.Instruction of the present invention can be applied to the equipment of other type easily.This is described content and is intended to explanation, and the scope of unrestricted claim.To those skilled in the art, various replacement schemes, remodeling and modification all are conspicuous.The feature of illustrative examples described here, structure, method and other characteristic can make up in many ways, with that obtain other and/or alternative exemplary embodiment.
Because under the situation that does not deviate from feature of the present invention, can realize feature of the present invention in a variety of forms, so it should also be understood that, unless otherwise noted, otherwise the foregoing description is not limited to any details described above, and should be interpreted as being positioned at the claims restricted portion synoptically, therefore, fall into the boundary of claim and whole modifications and the remodeling in the equivalents in scope or these boundaries and the scope and all will be contained by claims.
