ROTARY COMPRESSOR AND METHOD FOR MANUFACTURING THE SAME

The present invention relates to a rotary compressor for compressing an air conditioning refrigerant.

As this kind of compressor, the internal high pressure rotary compressor (hereinafter abbreviated as compressor) 100X shown in Figs. 7 and 8 is well known, for example. In the compressor 100X, the upper part of the airtight container 1 is provided with an electric mechanism part M made of a stator 2, a rotor 3, and the like, and a rotor 3 of the electric mechanism part M at a lower part thereof. ) And a compression mechanism (C) connected via a rotating shaft (4).

The compression mechanism (C) includes a cylinder (5), a compression chamber (8) formed by enclosing the surroundings with an upper bearing (6) and a lower bearing (7) sealing both ends thereof, an upper bearing (6), and a lower side. A cylindrical roller 9 which is installed by being fitted to the eccentric portion 4A of the rotating shaft 4 supported by the bearing 7 or loosely fitted, and which is eccentrically rotated by the rotation of the rotating shaft 4; The vane 10 which abuts against the outer circumference of the roller 9 and follows the eccentric rotation of the roller 9 to reciprocate and divides the compression chamber 8 into a low pressure part 8L and a high pressure part 8H. And a refrigerant of gas introduced through an accumulator (not shown) in the high pressure section (8H) of the compression chamber (8) and through the induction pipe (12) connected to the refrigerant outlet (11). A high pressure refrigerant ejected into the intermediate portion of the compression mechanism (C) and the electric mechanism (M) of It discharges from the discharge port 13 provided, and supplies a high pressure refrigerant | coolant to the refrigerant circuit of the air conditioner which is not shown in figure.

On the other hand, the electric motor part M provided in the upper part of the airtight container 1 rotates by the stator 2 fixed to the upper inner side of the airtight container 1, and the rotor field which the stator 2 forms. In addition to the rotor 3, the upper pressurizing member 14 provided above the rotating iron core of the rotor 3 and the lower pressurizing member 15 provided below are provided.

Each of the pressing members 14 and 15 is provided with a mass balance member 16 at an appropriate position, and has an eccentric portion 4A at its lower end with the rotary shaft 4 for eccentric rotation of the roller 9. The mass balance is held to suppress vibration.

In addition, 17 is an oil separation disk, and is attached to the rotating shaft 4 via the support rod 18. As shown in FIG. In the lower portion of the sealed container 1, the refrigeration oil 19 is collected, and the refrigeration oil 19 is pumped up to improve the lubrication and airtightness of the sliding portion of the compression mechanism (C).

Then, the compression mechanism (C) is compressed by the oil separation disc (17) rotates at high speed by the rotation of the rotor (3), the compression mechanism (C) of the sealed container (1) through the induction pipe (12). And a coolant vapor contacted to the disk 17 which rotates at a high speed in the process of ejecting from the discharge port 13 installed in the upper part of the sealed container 1 in the middle of the electric mechanism part M, and the coolant vapor thereof. The mist of the refrigeration oil contained in the pops out by the centrifugal force.

At that time, a stronger force is applied to the mist of the refrigeration oil having a higher density and the momentum is also large, so that the mist of the refrigeration oil contained in the refrigerant vapor is not decelerated, and the coil of the electric mechanism part M or the inner wall of the sealed container 1 are not decelerated. It is severely collided, and the speed is greatly reduced, and mists of the refrigeration oil condense and drop downward.

In the rotary compressor of the above-described configuration, the oil separating disc is attached to the rotating shaft of the electric machine part using a special rivet provided on the rotor for the purpose of only attaching the disc together with the supporting rod which is both dimensionally and mass. Because

① The need for a dedicated mold increases the cost of parts, and ② the mass increases, which leads to an increase in the utility input. Therefore, the disc for oil separation can be easily attached by a small, lightweight member. There is a need.

Moreover, in the rotary compressor of the said structure, the container body which heats and expands the rotor of the electric-mechanical part mounted in an inverted state to predetermined temperature, and forms a sealed container in the rotating shaft hole provided in the rotor. Since the part is conveyed in an inverted state and the rotor shaft is fitted with a rotating shaft fixed to the inside of the container body part, the rotor is shrunk and fixed to the rotating shaft, so that it is rotated by another method (for example, another production line). There is a problem that it is difficult to fix the former shrink.

The present invention has been made to solve the above-mentioned problems of the prior art.

It is a rotary compressor in which the member is integrated and the disc for oil separation is attached to the upper part of the rotor,

Insert the connecting means through one mounting hole of the oil separation disc or the upper plate member of the rotor and the mounting hole corresponding to the mounting hole, and then insert the connecting means through the other mounting holes. Since the disc for oil separation and the rotor upper plate member are integrated and the disc for oil separation is attached to the upper part of the rotor, a manufacturing method of the rotary compressor is performed. By connecting the connecting means with the small diameter of the mounting holes, and then passing the connecting means by matching the other mounting holes, the disc for oil separation and the upper plate member of the rotor are integrated. Even if the position of the mounting hole and the mounting hole of the rotor upper plate member is slightly shifted, extend the oil separation disc to the rotor upper plate member. It can be attached.

In addition, when blind rivets are used for the connecting means, the blind rivets of the connecting means pass through the attachment holes provided in the oil separating disc and the rotor upper plate-like member through the oil separating disc. Can be performed by a very simple operation of pulling the shaft portion.

In addition, the blind rivet is small in size and mass and is inexpensive. In addition, since the blind rivet is used for the connecting means, and the use of a special rivet or the like is not necessary, the component cost can be reduced and the useful input of the electric mechanism part can be reduced.

In addition, the present invention is a rotary compressor comprising a horizontal plate for oil separation, the rotary compressor to install a cutout in the outer peripheral portion of the upper plate member of the rotor with the oil separation disc, the sealed container The rotor main plate is positioned on the rotary shaft of the compression mechanism fixed to the inner side of the container body to be formed, and the rotor main body portion is shrunk and positioned based on the notch provided on the outer circumference of the rotor. It is a manufacturing method of a rotary compressor to be fixed, and the compression mechanism is fixed to the inside of the body portion of the container to form a hermetically sealed container by dangling the hanging rotor by engaging the suspending means to the notch provided in the outer peripheral portion of the rotor upper plate-like member Swivel fixed rotor main body to the rotating shaft of the shaft, and rotary pressure to fix the rotor of the electric mechanism to the rotating shaft As it is a manufacturing method of the meat machine,

By positioning the cutouts provided on the outer circumference of the upper plate member of the rotor with the eye mark, the rotor can be fixed to the rotating shaft, and the hook is hooked to the outer circumference of the upper plate member of the rotor where the cutout is installed. Suspension and conveyance can also be performed easily. Therefore, the rotor of the electric mechanism part can be attached to the rotating shaft assembled to the compression mechanism part even from the exclusive manufacturing line.
