본 발명은 회전자의 평형조정장치(balance control device)에 특징이 있는 회전피스톤형 압축기에 관한 것이다.The present invention relates to a rotary piston compressor characterized by a balance control device of the rotor.

회전피스톤형 압축기에 있어서, 회전자는 하우징 내에 편심으로 회전된다. 따라서 원심력이 회전축 및 하우징에 고르지 않게 가하여지는 경향이 있다.In a rotary piston type compressor, the rotor is rotated eccentrically in the housing. Therefore, the centrifugal force tends to be applied unevenly to the rotating shaft and the housing.

그러한 고르지 않게 가하여지는 원심력을 적절히 조정하기 위하여 이러한 형태인 종래의 압축기에는, 제1도에 도시한 바와 같이, 회전축 (1)상의 회전자 (3)의 중심에 대응하는 반대측에 평형추 (5) 및 평형풀리 (7)가 설치되어 있었다.In order to properly adjust such uneven centrifugal force, the conventional compressor of this type has a counterweight 5 on the opposite side corresponding to the center of the rotor 3 on the rotating shaft 1, as shown in FIG. And an equilibrium pulley 7 was installed.

그러나 전술한 종래의 압축기는 평형추 (5) 및 평형풀리 (7)가 하우징 (9)의 외측에 설치되기 때문에 회전피스톤형 압축기(P)가 큰 공간을 차지하게 되는 단점이 있다. 따라서 이 압축기 (P)가 차량 등에 설치되면 상당히 큰 공간이 소요된다.However, the conventional compressor described above has a disadvantage that the rotary piston type compressor P occupies a large space because the counterweight 5 and the counterweight pulley 7 are installed outside the housing 9. Therefore, when this compressor P is installed in a vehicle etc., a considerable space is required.

본 발명은 상기와 같은 문제점을 해결할 수 있는 압축기이다.The present invention is a compressor that can solve the above problems.

따라서 본 발명의 통상 목적은 회전피스톤형 압축기가 소형화될 수 있도록 회전자용의 평형조정장치를 포함하는 회전피스톤형 압축기를 제공하는 것이다.It is therefore a general object of the present invention to provide a rotary piston compressor including a balancing device for the rotor so that the rotary piston compressor can be miniaturized.

상기 목적을 달성하기 위해서는, 하우징과, 상기 하우징내에 편심으로 회전하는 회전자와, 이 회전자를 회전시킴과 동시에 평형추를 설치한 회전축으로 구성되고, 상기 평형추는 상기 회전축에 있는 축심을 중심으로 하여 상기 회전자의 중심과 반대측에 설치되어 있는 것이 특징인 회전피스톤형 압축기가 필수적으로 제공된다.In order to achieve the above object, it comprises a housing, a rotor which rotates eccentrically in the housing, and a rotating shaft which rotates the rotor and has a counterweight at the same time. Thus, a rotary piston type compressor, which is installed on the opposite side of the center of the rotor, is essentially provided.

본 발명의 중요한 특징중 하나는 상기 평형추가 상기 하우징내부에 설치된다는 사실이다.One of the important features of the present invention is the fact that the counterweight is installed inside the housing.

첨부된 도면을 참고로 하여 기술된 다음의 상세한 설명을 이해함으로서 본 발명이 속한 기술분야에서 통상의 지식을 가진자에게는 본 발명에 대한 상기 및 다른 목적 및 특성은 보다 명백하여 질 것이다.The above and other objects and features of the present invention will become more apparent to those skilled in the art by understanding the following detailed description described with reference to the accompanying drawings.

제2도 및 제3도에서, 11은 본 발명에 따른 회전 피스톤형 압축기의 하우징을 나타내면, 여기에는 한쌍의 흡입구멍(inlet ports)(13, 13) 및 한쌍의 배출구멍(outlet ports)(15, 15)이 포함된다(제3도 참조).In Figures 2 and 3, 11 represents the housing of the rotary piston compressor according to the invention, which has a pair of inlet ports 13, 13 and a pair of outlet ports 15 , 15) (see Figure 3).

17은 베어링을 통하여 하우징 (11)에 의하여 회전가능하게 지지된 회전축을 표시한다. 상기 회전축(17)의 한쪽 끝에는 종동기어 (19)가 스크류 수단에 의하여 견고하게 고정된다.17 denotes a rotation axis rotatably supported by the housing 11 through a bearing. At one end of the rotary shaft 17, the driven gear 19 is firmly fixed by screw means.

부재번호 21, 21은 하우징 (11)내의 회전축 (17)과 일체로 이루어진 크랭크아암을 표시한다.Reference numerals 21 and 21 denote crank arms which are integral with the rotation shaft 17 in the housing 11.

상기 크랭크아암 (21, 21)은 상기 회전자 (23)를 회전가능하게 움직인다. 25, 25는 회전자 (23)의 뒤에 설치된 내측기어를 표시한다.The crank arms 21 and 21 rotatably move the rotor 23. 25 and 25 represent inner gears installed behind the rotor 23.

상기 내측기어는 하우징 (11)에 고정된 고정기어(stationary gear)와 맞물려 있으며 상기 고정기어(27, 27)는 회전축 (17)에 헐겁게 맞추어진다. 이때문에 회전축 (17)이 회전하면 회전자 (23)는 고정기어(27, 27)와 함께 내측기어 (25, 25)에 맞물려 편심으로 회전하게 된다.The inner gear is engaged with a stationary gear fixed to the housing 11 and the fixed gears 27 and 27 are loosely fitted to the rotary shaft 17. For this reason, when the rotating shaft 17 rotates, the rotor 23 meshes with the inner gears 25 and 25 together with the fixed gears 27 and 27 to rotate eccentrically.

다음에, 29는 회전자 (23)의 중심의 반대편 중앙부에 회전축 (17)과 함게 통상 요우크(yoke)형태로 전체가 이루어진 추 설치부재(weight mounting member)를 표시한다. 상기 추 설치부재 (29)는 반원통형(semi-cylindrical shape)이며 리세스(recess)(31)를 갖는 평면에 설치된다.Next, 29 denotes a weight mounting member made entirely in the form of a yoke with a rotating shaft 17 at the center opposite the center of the rotor 23. The weight mounting member 29 is semi-cylindrical shape and is installed in a plane having a recess 31.

33은 스크류수단에 의하여 상기 리세스 (31)에 고정된 평형추를 표시한다.33 denotes a counterweight fixed to the recess 31 by screwing means.

상기 평형추 (33)는 로우터리 회전자(rotary rotor)(23)가 회전하면 그때 회전축 (17)과 베어링에 가해지는 하중의 평형의 조정하기 위하여 설치된다.The counterweight 33 is provided for adjusting the balance of the load applied to the rotating shaft 17 and the bearings when the rotary rotor 23 rotates.

전술한 바와 같이, 본 발명에 따른 회전피스톤형 압축기는 하우징과, 상기 하우징내에서 편심으로 회전하는 회전자와 이 회전자를 회전시킴과 동시에 형형추를 설치한 회전축으로 구성되고, 상기 형형추는 상기 회전축에 있는 축심을 중심으로 하여 상기 회전자의 중심과 반대측에 설치되고 또한 상기 하우징 내부에 설치되어 있는 것을 특징으로 한다.As described above, the rotary piston compressor according to the present invention comprises a housing, a rotor which rotates eccentrically in the housing, and a rotating shaft which rotates the rotor and installs a shape weight at the same time. It is characterized in that it is installed on the opposite side to the center of the rotor centered on the shaft center in the rotation shaft and installed inside the housing.

즉, 본 발명의 회전피스톤형 압축기에 있어서, 형형추는 통상의 압축기와는 반대로, 하우징의 내부에 설치된다. 따라서 압축기의 전크기는 소형화될 수 있다. 또한 자동차 또는 그와 유사한 곳에 설치되어도 큰 공간이 차지하지 않게 된다.That is, in the rotary piston compressor of the present invention, the mold weight is provided inside the housing as opposed to the ordinary compressor. Therefore, the full size of the compressor can be miniaturized. In addition, even if installed in a car or the like will not occupy a large space.

게다가 이 압축기는 하우징내에 평형추를 갖고 있으므로 하우징의 외측엔 장애물이 없어, 취급이 용이하게 된다.In addition, since the compressor has a counterweight in the housing, there are no obstacles on the outside of the housing, and handling is easy.

또한 평형추가 분리 가능한 방법으로 설치되면 추의 조정을 용이하게 할 수 있으며 마찬가지로, 회전축과 다른 중량을 갖는 재료가 사용된다면 체적을 감소시킬 수 있다.The counterweight can also be installed in a detachable manner to facilitate adjustment of the weight and likewise to reduce the volume if a material having a different weight than the axis of rotation is used.

비록 본 발명이 실시예에 따라 전술되었을 지라도 본 발명의 정신내에서 많은 수정과 변경이 가능할 것이다.Although the invention has been described above in accordance with embodiments, many modifications and variations will be possible within the spirit of the invention.
