Description
The present invention relates to a kind of closed compressor, particularly a kind of improved oil rig that is used for closed compressor, it is by providing a system, in this system, will pump propeller cavitation and oil-deflecting element integral forming, and make and be formed on this oil-deflecting element outer peripheral a pair of projection fastener under being formed at the closed compressor bent axle on the inner periphery in the corresponding grooves, thereby reduced manufacture cost, simplified production stage.
As shown in Figure 1, be an existing closed compressor, it comprises a seal container 1 as compressor case, is equipped with a stator 3 and a rotor 4 in container 1.
A pair of support spring 2a, 2a are connected on the inwall of sealed container 1, support spring 2a, and the last end bearing of 2a framework 2.
Bent axle 5 hot chargings that the top has an eccentric part 5a fit in the rotor 4.Cylinder 6 is connected the top of framework 2.
Making the piston 7 of horizontal reciprocating movement and the eccentric part 5a of bent axle 5 in cylinder 6 links together.
End at cylinder 6 is equipped with a cylinder end piece member 8, makes cooling gas can pass in and out cylinder 6.
, be contained in the refrigeration oil " O " of container 1 bottom herein, send corresponding parts forth, to alleviate the wearing and tearing that cause by friction in the compressor.
For refrigeration oil " O " is extracted in the oil circuit that is arranged in bent axle 5, provides a cylindrical shape oil-deflecting element 10 to constitute oil rig 9, and it has been embedded the lower end of bent axle 5.
As shown in Figure 2, connect oil-deflecting element 10 and constitute oil circuit 10a, and oil pumping propeller cavitation 11 embedded being contained among the oil circuit 10a.
At this moment, oil-deflecting element 10 and oil pumping propeller cavitation 11 bottom separately are immersed in the refrigeration oil " O " that is full of the closed compressor bottom.
Fig. 3 is the decomposition view of oil pumping propeller cavitation 11 and oil-deflecting element 10.
Referring to figs. 1 through Fig. 3, the oil pumping action of the existing closed compressor of this structure is described now.
Connect power supplys for stator 3, during rotor 4 entrys into service, the bent axle 5 that is fixed on the rotor 4 begins rotation, and the piston 7 that is connected on the eccentric part 5a of bent axle 5 is reciprocating in cylinder 6.
The to-and-fro motion of piston 7 makes the cooling gas of low-temp low-pressure enter cylinder 6, and the cooling gas that will enter the low-temp low-pressure of cylinder changes high-temperature high-pressure state into, with after cylinder end piece member 8 discharge.
Simultaneously, be positioned at the bottom of bent axle 5 owing to comprise the oil rig 9 of oil-deflecting element 10 and oil pumping propeller cavitation 11; When bent axle 5 rotations, refrigeration oil " O " is drawn onto along among the oil circuit 5b of bent axle 5, and is distributed to the part place that there is friction in closed compressor.
Particularly, when the bent axle 5 in the existing closed compressor began to rotate, the fixing oil-deflecting element 10 (one of member of oil rig 9) that inserts bent axle 5 bottoms rotated thereupon; And the oil pumping propeller cavitation 11 of yielding support in oil-deflecting element 10 is along with oil-deflecting element 10 rotates together.Rotatory force makes refrigeration oil " O " flow into the oil circuit 10a and the oil circuit 5b that is arranged on the bent axle 5 of oil-deflecting element 10 in succession like this.
Yet there is following shortcoming in the existing oil rig that is used for closed compressor:
At first, oil pumping propeller cavitation and oil-deflecting element should be made respectively, and assembling again except that increasing production process, also brings and makes and the assembly cost rising like this.
Secondly, oil pumping propeller cavitation and oil-deflecting element are assembled with each other, when reinstalling in the bent axle, may have metal fragment, thereby reduce its efficient and life-span, and bring the operation troubles in the closed compressor.
Therefore, an object of the present invention is to provide a kind of oil rig that is used for closed compressor, this device is made integrated component by an oil pumping propeller cavitation and oil-deflecting element, and reduces manufacture cost and simplify its assembly process.
For achieving the above object, provide a kind of oil rig of closed compressor.It comprises an oil-deflecting element, and this oil-deflecting element is connected with the bottom of the bent axle of closed compressor regularly; An oil pumping propeller cavitation that is fixed in the oil-deflecting element when it rotates along with the rotation of bent axle, is then pumped by bent axle, wherein oil-deflecting element and the integrated member of oil pumping propeller cavitation.
It is clearer that other purpose of the application will become in the following description.Yet, should be understood that to be explanation the preferred embodiments of the present invention that detailed description that provides and specific example are just in order to illustrate the present invention.Obviously, for those skilled in the art,, can carry out various improvement and correction not breaking away under the spirit and scope of the invention by these detailed descriptions.
Accompanying drawing is just understood the present invention better for help, rather than restriction the present invention, in the accompanying drawing:
Fig. 1 is the sectional view of an existing closed compressor;
Fig. 2 is the sectional view of existing fixed oil rig on the bent axle in closed compressor;
Fig. 3 is the decomposition view that is used for the existing oil rig of closed compressor;
Fig. 4 is according to the preferred embodiments of the present invention, is installed in the sectional view of the oil rig on the bent axle of closed compressor;
Fig. 5 is the sectional view that is used for the oil rig of closed compressor according to of the present invention; Wherein pump propeller cavitation and oil-deflecting element integral forming;
Fig. 6 is the plane view that is used for the oil rig of closed compressor according to of the present invention, wherein pump propeller cavitation and oil-deflecting element integral forming.
Referring now to accompanying drawing, the oil rig that is used for closed compressor of the present invention is described.
As shown in Figure 4, according to the present invention, be used for the integrated member of oil rig of closed compressor, it comprises an oil pumping propeller cavitation 100a and an oil-deflecting element 100.
And then as illustrated in Figures 5 and 6, the integrated component by oil-deflecting element 100 and oil pumping propeller cavitation 100a constitute has a pair of projection 100b that is positioned at outer rim on this member; With a pair of groove 105a that is positioned at 105 times inner periphery of bent axle, thereby projection 100b fastener is in corresponding groove 105a.
According to the present invention, the oil rig of the integral forming in the closed compressor comprises oil-deflecting element and oil pumping propeller cavitation; Its operation is similar with the situation that has the oil rig in the closed compressor now.
Oil-deflecting element 100 by the projection 100b fastener above it in groove 105a, it is rotated along with the rotation of bent axle 105, and the oil pumping propeller cavitation 100a that is arranged in oil-deflecting element 100 this moment also rotates together, thereby, corresponding to the rotatory force that is added on bent axle 105 and the oil-deflecting element 100, make the refrigeration oil " O " that is full of the closed compressor bottom be introduced in the bent axle 105.
Above-mentioned integrated component comprises oil-deflecting element 100 and the oil pumping propeller cavitation 100a that is positioned at wherein, and the material of its available molded oil-deflecting element 100 and propeller cavitation 100a is integral.
