At this, first running shaft 561 and second running shaft 361 are independent component, therefore, and in a little gap of linking department 87 generations of first running shaft 561 and second running shaft 361.But and since linking department 87 around be bonded member 84 and cover, so lubricant oil is suppressed from the leakage of linking department 87.
Next, the assembling method about fluid machinery 5F describes.
Fluid machinery 5F when assembling, at first, prepare the tube portion 11 of seal container 10, at the stator 72 and the installation component 452 of the inwall engage motor 23 of tube portion 11.Next, insert, the inwall of compressing mechanism 21 with tube portion 11 engaged being fixed with the end (end of the upside of Fig. 2) of the compressing mechanism 21 of stator 71 on first running shaft 561 from tube portion 11.Next, on installation component 452, clutch shaft bearing member 47c is set, carry out the accent core operation with first running shaft 561 after, utilize not shown bolt that clutch shaft bearing member 47c is tightened toward installation component 452.Next, the other end (end of the downside of Figure 14) of expansion mechanism 220 from tube portion 11 inserted, at the chimeric in advance linking member 84 in the outside of the binding end of first running shaft 561 56t, from second running shaft 361 being entrenched on the linking member 84, first running shaft 561 and second running shaft 361 are linked with first running shaft, 561 opposition sides.Utilize not shown bolt expansion mechanism 220 and installation component 452 is fastening thereafter.
Other aspects and first mode of execution are same.
As previously discussed, according to present embodiment, the running shaft 561 of compressing mechanism 21 and the running shaft of expansion mechanism 220 361 are independent individual, via linking member 84 two running shafts 361,561 are linked, so compressing mechanism 21 and expansion mechanism 220 become easy with respect to the assembling of seal container 10.
In addition, according to present embodiment, linking member 84 is configured in the inside of upper bearing (metal) 47, is covered by upper bearing (metal) 47.Thereby lubricant oil is difficult for leaking from linking department 87 (gap between running shaft 361 and the running shaft 561).Thereby, to be positioned at upside as the compressing mechanism 21 of rotating machinery also supplying lubricating oil stably.
In addition,, leak from linking department 87, therefore, can suppress lubricant oil and flow out to the outside of seal container 10 from spraying pipe 7 with refrigeration agent owing to can suppress lubricant oil according to present embodiment.Thereby, can prevent the lubricant oil deficiency in the seal container 10.
Also have, among this fluid machinery 5F, positioning error when making and thermal distortion etc. in order to absorb, and the gap of Rack is set between first running shaft 561 and second running shaft 361.Thereby imagination lubricant oil is from this clearance leakage., the lubricant oil of leakage to the part that needs lubricant oil in essence, be to supply with between the clutch shaft bearing member 47c and first running shaft 561 or between the second bearing components 47d and second running shaft 361, therefore effectively utilize lubricated in slide part.Thereby,, sealing components such as O ring need be set in order to prevent oil leak according to present embodiment.Thereby, according to present embodiment, can cut down components number.In addition, the problem that can avoid sealing component to worsen.
Also have, in the present embodiment, the gap (with reference to Figure 15) of Rack is set between the inner peripheral surface of the outer circumferential face of linking member 84 and clutch shaft bearing member 47c, linking member 84 itself is not supported by clutch shaft bearing member 47c.But, also can be by clutch shaft bearing member 47c supporting linking member 84.At this moment, it is chimeric that first running shaft 561 and second running shaft 361 carry out so-called spline with respect to linking member 84, and linking member 84 is by clutch shaft bearing member 47c supporting and can rotate.Thereby binding end 36t, the 56t of two running shafts 361,561 are bearing on the clutch shaft bearing member 47c via linking member 84.Thereby two running shafts 361,561 can be stably supported in rocking in the time of can suppressing 361,561 rotations of two running shafts.
According to present embodiment, to be pressed into state chimeric with non-respectively with respect to linking member 84 for first running shaft 561 and second running shaft 361.Thereby, can be easily that first running shaft 561 and second running shaft 36 1 is chimeric with respect to linking member 84, can improve assembling performance.
But, also the one of any of first running shaft 561 and second running shaft 361 can be pressed on the linking member 84.For example, also first running shaft 561 can be pressed on the linking member 84, second running shaft 361 is pressed into state and linking member 84 is chimeric with non-.At this moment, lubricant oil is difficult for from leaking between first running shaft 561 and the linking member 84.Thereby the lubricant oil that flows through the fuel feeding road 38 of the second running shaft 361 fuel feeding road 68 of first running shaft 561 of flowing through is mostly supplied with to compressing mechanism 21.On the other hand, to be pressed into state chimeric with non-for second running shaft 361 and linking member 84, and therefore, second running shaft 361 is easy with the assembling of linking member 84, can not damage assembling performance.
Also have, the chimeric shape of first running shaft 561 and second running shaft 361 and linking member 84 is not limited to spline-shaped as the present embodiment.For example, also can be as shown in figure 18, the profile of the outer circumferential side of the cross section of binding end 56t and binding end 36t forms the hexagon shape, and the profile of interior all sides of the cross section of linking member 84 forms and above-mentioned binding end 56t and the corresponding hexagon shape of binding end 36t.In addition, can also be that the profile of outer circumferential side that links end 56t and link the cross section of end 36t forms polygon-shaped beyond the hexagon shape, the profile of interior all sides of the cross section of linking member 84 forms with above-mentioned binding end 56t and links corresponding polygon-shaped of end 36t.
According to the fluid machinery 5F of present embodiment, to compare with the situation that two running shafts 361,561 are directly chimeric each other, two running shafts 361,561 all can not reduce to link the external diameter of end 36t, 56t.Thereby, can guarantee so-called transmission of torque radius significantly, therefore can improve the reliability of linking member 87.
