Abstract
The utility model discloses an oil-supply apparatus for a vertical compression engine. The upper end of a spiral pump vane is provided with an expanding part, the width B of the expanding part is bigger than the inner diameter D of the hollow hole of a crankshaft, and a slit in length is arranged at the center of the expanding part in width. The spiral pump vane is inlaid and inserted in the hollow hole of the crankshaft, the left and the right end surfaces of the expanding part can be pressed by the inner wall of the hollow hole because the width B of the expanding part is bigger than the inner diameter D of the hollow hole, and as a result, the expanding part can be elastically deformed towards the inside, and the spiral pump vane can be firmly fixed on the crankshaft due to resilient forces.
Description
The utility model relates to the used oil supplying device of vertical compressor, relates in particular to the technology of the installation capability raising that makes the volute pump blade.
Comprise compressor in the used device of the freeze cycle of air conditioner, refrigerating machine etc.Up to the present, for compressor, having proposed the scheme of various mechanisms by its purposes, but be used for indoor air-cooling system or refrigerator, mainly is noise and the little rotor-type compressor of vibration.
Fig. 4 shows the longitudinal section of vertical rotor compressor.In the cylinder body 2 in being fixed in shell 1, the roller 4 that is embedded on the bent axle 3 is made eccentric rotary by motor 5 drivings.Be compressed the outer circumferential face sliding contact of slide plate (Block レ-De) 7 and roller 4 of sliding blade spring 6 active forces of coiled type, eccentric rotary along with roller 4, the volume in the space that is surrounded by roller 4, cylinder body 2 and slide plate 7 changes, and carries out the suction and the compression of gas refrigerant.
The main bearing 8 and supplementary bearing 9 rotatably supports of the top and bottom of bent axle 3 by being fixed in cylinder body 2.The place, axle center of bent axle 3 is provided with hollow hole 10, at these hollow hole 10 embedded volute pump blades 11 that are inserted with steel plate system.Volute pump blade 11 protrudes in the lower end surface of bent axle 3, and its lower end extends near the inner bottom surface of shell 1.The lower end of hollow hole 10 has been pressed into pump case 12 cylindraceous, is accommodating volute pump blade 11.Among Fig. 4, the 13rd, be located at the oilhole on the bent axle 3.
In case bent axle 3 rotates, volute pump blade 11 also rotates simultaneously.So, because the pump-absorb action of volute pump blade 11, accumulate lubricant oil 14 in pump case 12 and be inhaled into from the bottom of shell 1 and rise in the hollow hole 10.The lubricant oil that is filled in the hollow hole 10 is supplied to the inboard of roller 4 through oilhole 13, is lubricated between bent axle 3 and roller 4 and two bearings 8,9.
Traditional compressor has adopted following method for volute pump blade 11 is fixed in the hollow hole 10 of bent axle 3.
Shown in Figure 5, be the method that when volute pump blade 11 is shaped, gives warpage.In this example, after 11 intercalations of volute pump blade are in hollow hole 10, be pressed into pump case 12 again.So volute pump blade 11 shown in the two point dotted line resiliently deformable takes place, because its rebounding force, volute pump blade 11 is fixed on the inwall of hollow hole 10 and pump case 12.
Shown in Fig. 6, Fig. 7 (view of the arrow A direction among Fig. 6), be that the end portion with volute pump blade 11 is two, and these two blades are crooked round about respectively and form the method for card claw stop 15.In this example, if 11 intercalations of volute pump blade are pressed in the hollow hole 10, card claw stop 15 promptly embeds the inwall of the hollow hole 10 of bent axle 3, makes volute pump blade 11 fixing.
There is following shortcoming in the fixation method of above-mentioned volute pump blade 11.
That is, preceding a kind of method that gives volute pump blade 11 warpages, enough big because the elastic deformation amount of steel plate can not obtain, so can not firmly fix.Again because the long-term back retention force that uses can descend, so volute pump blade 11 might little by little no longer rotate and the pump-absorb action that do not recur with bent axle 3.On the other hand, a kind of method that forms hooking sheet 15 in the underpart of volute pump blade 11 in back is in the lower end of bent axle 3 device of pump case 12 being installed, because can not be pressed into hooking sheet 15, so inapplicable.
Therefore, the purpose of this utility model is, solves the problem that above-mentioned prior art exists, and a kind of oil supplying device that can make the volute pump blade be fixed on the vertical compressor in the hollow hole reliably is provided.
In order to achieve the above object, the oil supplying device of the vertical compressor that the utility model relates to is that a kind of axle center at bent axle is provided with hollow hole, at the embedded oil supplying device that is inserted with the vertical compressor that sucks the volute pump blade that lubricant oil uses of this hollow hole, it is characterized in that, be provided with pump case cylindraceous in described hollow hole lower end, in the upper end portion of described volute pump blade or the intermediate portion have expanding portion than the internal diameter amplitude broad of described hollow hole, this volute pump blade is set to described pump case from hollow hole, and described expanding portion engages with hollow hole inwall elasticity.
According to the utility model, if the intercalation of volute pump blade is gone in the hollow hole of bent axle, the two end part of expanding portion just can be subjected to the pushing of hollow hole inwall, realize firm fixing.
The simple declaration of accompanying drawing:
Fig. 1 is the side view according to the utility model the 1st embodiment's volute pump blade.
Fig. 2 is the sectional view of installment state that the 1st embodiment's volute pump blade is shown.

17: slit
Following with reference to accompanying drawing, the embodiment according to oil supplying device of the present utility model is described.When explanation embodiment, identical symbol enclosed by the member identical with above-mentioned conventional apparatus and the repetitive description thereof will be omitted.
In the 1st embodiment shown in Figure 1, the upper end of volute pump blade 11 is formed with expanding portion 16.The width B of expanding portion 16 is represented with double dot dash line than bent axle 3() the inside diameter D of hollow hole 10 big, at the center of its width direction, be formed with slit 17 along its length.For ease of inserting in the hollow hole 10, the upper end is provided with chamfering 18 about expanding portion 16.
Under the situation of volute pump blade 11 intercalations in the hollow hole 10 of bent axle 3 with present embodiment, because the width of expanding portion 16 is greater than the inside diameter D of hollow hole 10, so the left and right sides end face of expanding portion 16 is subjected to the pushing of the inwall of hollow hole 10.Its result as shown in Figure 2, expanding portion 16 is resiliently deformable to the inside because its rebounding force, volute pump blade 11 is securely fixed on the bent axle 3.
In the 2nd embodiment shown in Figure 3, be provided with expanding portion 16 in the intermediate portion of the above-below direction of volute pump blade 11.The same with the 1st embodiment, the width B of expanding portion 16 is formed with the slit 17 of length direction greater than the inside diameter D of bent axle (representing with double dot dash line) hollow hole 10 at the center of its width direction.
The effect of present embodiment is also basic identical with the 1st embodiment, expanding portion 16 produces resiliently deformable to the inside, because its rebounding force, volute pump blade 11 is fixed, but because the position of expanding portion 16 is near the underpart of bent axle 3, so the former is little for the resistance ratios during intercalation.
