Description
본 발명은 압축기에 관한 것으로, 특히 회전축에 동흡진기를 장착하여 회전시 발생하는 회전체의 고유주파수를 흡수하도록 한 압축기의 진동 저감 장치에 관한 것이다.The present invention relates to a compressor, and more particularly, to a vibration reduction device of a compressor in which a copper reducer is mounted on a rotating shaft to absorb a natural frequency of a rotating body generated during rotation.
일반적으로 압축기는 전동기구부의 구동력을 압축기구부에 전달하여 유체를 압축하는 것으로, 유체의 압축 방식에 따라 왕복동식,회전식,스크롤식 등으로 구분할 수 있다.In general, a compressor compresses a fluid by transmitting a driving force to a compressor mechanism, and may be classified into a reciprocating type, a rotary type, and a scroll type according to the compression method of the fluid.
이러한 압축기들은 대개 압축기구부가 전동기구부에 편심되게 결합하여 회전시 불균형 질량과 압축력으로 인한 진동이 발생하고 이 진동에 의해 회전체의 운동이 불안정하게 될 우려가 있어 종래에는 회전자에 밸런스 웨이트를 장착하는 방안이 알려져 왔다.In these compressors, the compressor mechanism is eccentrically coupled to the electric mechanism, and vibrations due to unbalanced mass and compression force may occur during rotation, and the movement of the rotor may be unstable due to the vibration. Ways to do this have been known.
도 1은 종래 밸런스 웨이트를 구비한 로터리 압축기의 일례를 보인 종단면도이다.1 is a longitudinal sectional view showing an example of a rotary compressor having a balance weight in the related art.
이에 도시한 바와 같이 종래의 로터리 압축기는, 흡입관(SP)과 토출관(DP)을 구비하는 케이싱(1)의 내부에 설치하여 인가된 전원에 의해 구동력을 발생하는 전동기구부와, 전동기구부에 회전축(6)으로 연결하여 냉매가스를 압축하는 압축기구부로 구성되어 있다.As shown in the drawing, a conventional rotary compressor is provided in a casing (1) having a suction pipe (SP) and a discharge pipe (DP). It is composed of a compressor mechanism for connecting refrigerant (6) to compress the refrigerant gas.
전동기구부는 케이싱(1)의 상반부에 압입하여 고정하는 고정자(2)와, 고정자(2)의 내부에 회전 가능하게 배치하는 회전자(3)와, 회전자(3)의 상하 양측에 각각 고정하여 회전자(3)의 불균형 질량을 감쇠하는 밸런스 웨이트(4A,4B)로 이루어져 있다.The electric mechanism is fixed to the stator 2 which is press-fitted into the upper half of the casing 1, the rotor 3 rotatably disposed inside the stator 2, and the upper and lower sides of the rotor 3, respectively. And the balance weights 4A and 4B for damping the unbalanced mass of the rotor 3.
압축기구부는 흡입관(SP)과 연통하도록 케이싱(1)의 하반부에 고정하는 실린더(5)와, 실린더(5)의 상하 양 측면에 밀착되어 실린더(5)의 밀폐공간을 형성함과 아울러 회전축(6)을 반경방향으로 지지하는 상부베어링(7A) 및 하부베어링(7B)과, 회전축(6)의 편심부에 삽입되어 자전하면서 냉매가스를 압축하는 롤링피스톤(8)과, 롤링피스톤(8)의 외주면에 반경방향으로 압접하여 실린더(5)의 밀폐공간을 흡입공간과 압축공간으로 구분하는 베인(미도시)을 포함하여 이루어져 있다.The compression mechanism is in close contact with the cylinder 5 fixed to the lower half of the casing 1 so as to communicate with the suction pipe SP, and the upper and lower sides of the cylinder 5 to form a closed space of the cylinder 5, The upper bearing 7A and the lower bearing 7B for radially supporting 6), the rolling piston 8 inserted into the eccentric portion of the rotating shaft 6 to compress the refrigerant gas while rotating, and the rolling piston 8 It comprises a vane (not shown) for radially contacting the outer circumferential surface of the cylinder 5 divided into a suction space and a compression space.
도면중 미설명 부호인 6a는 오일구멍, 7a는 토출구멍, 9는 토출머플러이다.In the figure, reference numeral 6a denotes an oil hole, 7a a discharge hole, and 9 a discharge muffler.
상기와 같은 종래의 밀폐형 회전식 압축기는 다음과 같이 동작한다.The conventional hermetic rotary compressor as described above operates as follows.
즉, 전동기구부에 전원을 인가하면, 회전자(3)가 고정자(2)의 내부에서 회전하고, 이와 함께 회전축(6)이 회전하면서 롤링피스톤(8)이 실린더(5)내에서 편심 회전을 하며, 냉매가스가 실린더(6)의 흡입공간으로 흡입하여 일정압력까지 압축되다가 압축가스의 압력이 임계압력 보다 높아진 순간 토출구멍(7a)을 통해 케이싱(1)의 내부로 토출하고, 케이싱(1)과 고정자(2) 사이의 틈새 또는 고정자(2)와 회전자(3) 사이의 틈새 등을 통해 케이싱(1)의 상부로 이동하여 토출관(DP)을 거쳐 냉동사이클시스템으로 배출한다.That is, when electric power is applied to the electric mechanism, the rotor 3 rotates inside the stator 2, and the rotating shaft 6 rotates together with the rolling piston 8 to perform eccentric rotation in the cylinder 5. The refrigerant gas is sucked into the suction space of the cylinder 6, compressed to a predetermined pressure, and discharged into the casing 1 through the discharge hole 7a at the moment when the pressure of the compressed gas is higher than the threshold pressure. ) And through the gap between the stator (2) or the stator (2) and the rotor (3) to the upper portion of the casing (1) to discharge through the discharge pipe (DP) to the refrigeration cycle system.
이때, 회전축(6)에는 편심부가 형성되어 회전시 불균형 질량에 의한 가진력(加振力:exciting force)은 물론 냉매가스의 압축시 가스력에 의한 가진력이 발생하고, 그 가진력에 의해 회전자(6)가 편심져 회전하면서 고정자(2)의 내주면을 긁을 우려가 있으나, 회전자(3)의 상하 양측에 장착한 밸런스 웨이트(4A,4B)가 불균형 질량에 의한 가진력을 상당 부분 감쇠하여 압축기가 좀더 안정적으로 동작할 수 있게 되는 것이었다.At this time, the eccentric portion is formed on the rotating shaft 6 to generate the excitation force due to the unbalanced mass during rotation, as well as the excitation force due to the gas force during the compression of the refrigerant gas, and the rotor 6 by the excitation force. ) May scratch the inner circumferential surface of the stator (2) while rotating, but the balance weights (4A, 4B) mounted on the upper and lower sides of the rotor (3) attenuate the excitation force due to the unbalanced mass to a large extent. It was to be able to operate stably.
그러나, 상기와 같은 로터리 압축기에 있어서는, 전술한 바와 같이 편심부를 구비한 회전축(6)이 회전자와 함께 회전을 하면서 냉매가스를 압축하는 과정에서 불균형 질량에 의한 규칙적인 가진력과 냉매가스가 압축하면서 가스력에 의한 불규칙한 가진력이 함께 발생함에도 불구하고 종래에는 불균형 질량에 의한 가진력만을 고려하여 회전자(3)의 양측에 불균형 질량을 보상하기 위한 밸런스 웨이트(4A,4B)만을 구비함으로써 결과적으로 가스력에 의한 가진력까지는 효과적으로 감쇠할 수 없었다.However, in the rotary compressor as described above, while the rotary shaft 6 having the eccentric portion rotates together with the rotor as described above, the regular excitation force and the refrigerant gas are compressed by the unbalanced mass while compressing the refrigerant gas. In spite of the occurrence of irregular excitation due to the gas force, conventionally, only the balance weights 4A and 4B are provided on both sides of the rotor 3 in consideration of the excitation force due to the unbalanced mass. Excitation force by could not be effectively attenuated.
본 발명은 상기와 같은 종래 로터리 압축기의 문제점을 감안하여 안출한 것으로, 불균형 질량에 의한 규칙적인 가진력은 물론 가스력에 의한 불규칙적인 가진력도 효과적으로 감쇠할 수 있는 압축기의 진동 저감 장치를 제공하려는데 그 목적이 있다.The present invention has been made in view of the problems of the conventional rotary compressor as described above, to provide a vibration reduction device of the compressor that can effectively attenuate not only regular excitation force due to unbalanced mass but also irregular excitation force due to gas force. There is this.

이에 도시한 바와 같이 본 발명에 의한 진동 저감 장치를 구비한 로터리 압축기는, 케이싱(1)의 상반부에 고정하는 고정자(2)와, 고정자(2) 내부에 회전 가능하게 배치하는 회전자(3)와, 케이싱(1)의 하반부에 고정하는 실린더(5)와, 실린더(5)를 관통하도록 회전자(3)에 결합하여 함께 회전하는 회전축(6)과, 실린더(5)의 상하 양 측면에 결합하는 상부베어링(7A) 및 하부베어링(7B)과, 회전축(6)의 편심부에 삽입하여 자전하면서 냉매가스를 압축하는 롤링피스톤(8)과, 롤링피스톤(8)의 외주면에 반경방향으로 압접하여 실린더(5)의 밀폐공간을 흡입공간과 압축공간으로 구분하는 베인(미도시)과, 회전축(6)의 하단에 결합하여 회전체의 고유한 주파수를 흡수하는 동흡진기(100)를 포함하여 구성된다.As shown therein, the rotary compressor including the vibration reduction device according to the present invention includes a stator 2 fixed to the upper half of the casing 1 and a rotor 3 rotatably disposed inside the stator 2. And a cylinder (5) fixed to the lower half of the casing (1), a rotating shaft (6) coupled to the rotor (3) so as to pass through the cylinder (5) and rotated together, and on both upper and lower sides of the cylinder (5). The upper bearing 7A and the lower bearing 7B to be joined, the rolling piston 8 which is inserted into the eccentric portion of the rotating shaft 6 and compresses the refrigerant gas while rotating, and the outer circumferential surface of the rolling piston 8 in the radial direction. And a vane (not shown) for pressing and dividing the closed space of the cylinder 5 into a suction space and a compression space, and a copper reducer 100 coupled to the lower end of the rotating shaft 6 to absorb a unique frequency of the rotating body. It is configured by.
회전자(3)의 상하 양측에는 회전축(6)의 편심부로 인한 가진력을 감쇠하는 밸런스 웨이트(4A,4B)를 각각 장착한다.Balance weights 4A and 4B are mounted on the upper and lower sides of the rotor 3 to attenuate the excitation force due to the eccentric portion of the rotary shaft 6, respectively.
동흡진기(100)는 도 4 및 도 5에 도시한 바와 같이 원판을 "차륜" 모양으로 형성하는 것으로, 회전축(6)에 고정하는 환형의 고정부(110)와, 고정부(110)의 외주면에서 낱개로 방사상 연장하는 장방형의 탄성부(120)들과, 각 탄성부(120)들의 바깥단을 연결하는 환형의 질량부(130)로 이루어진다.As shown in FIGS. 4 and 5, the copper reducer 100 forms a disc in a “wheel” shape, and includes an annular fixing part 110 fixed to the rotating shaft 6 and an outer circumferential surface of the fixing part 110. It consists of a rectangular elastic portion 120 extending radially to each other, and an annular mass portion 130 connecting the outer end of each elastic portion 120.
탄성부(120)는 본 실시예와 같이 방사상으로 길게 하여 형성할 수도 있으나, 경우에 따라서는 이미 알려진 스파이럴 스프링과 같이 나선형이나 그 외에 다양하게 형성할 수도 있다.The elastic part 120 may be formed to be radially long as in this embodiment, but in some cases, may be formed in a spiral or other various forms, such as a spiral spring known in the art.
질량부(130)는 본 실시예에서와 같이 환형으로 형성할 수도 있으나, 경우에 따라서는 각각의 탄성부(120)에 낱개의 질량체(미도시)를 연장하거나 조립하여 형성할 수도 있다. 하지만 압축기의 안정성을 고려하면 본 실시예와 같은 환형이 바람직하다.The mass portion 130 may be formed in an annular shape as in the present embodiment, but in some cases, may be formed by extending or assembling a single mass body (not shown) in each elastic portion 120. However, considering the stability of the compressor, the annular shape as in the present embodiment is preferable.
또, 질량부(130)는 동흡진기(100)의 재질을 결정하면 그에 따른 탄성부(120)의 스프링 상수가 결정됨과 동시에 질량부(130)의 필요 관성모멘트가 결정되므로, 이를 토대로 회전축(6)이 갖는 특정한 고유주파수에 조응하도록 질량부(130)의 무게에 관련한 폭이나 직경을 결정하여 동흡진기(100)의 고유주파수를 조정할 수 있다.In addition, if the mass portion 130 determines the material of the copper reducer 100, the spring constant of the elastic portion 120 is determined and the required moment of inertia of the mass portion 130 is determined.

In this case, the excitation force due to the unbalanced mass may be applied together with the balance weights 4A and 4B mounted on the rotor 3. Can be attenuated more effectively.
도면중 종래와 동일한 부분에 대하여는 동일한 부호를 부여하였다.In the drawings, the same reference numerals are given to the same parts as in the prior art.
도면중 미설명 부호인 6a는 오일구멍, 7a는 토출구멍, 9는 토출머플러, 110a는 관통구멍이다.In the figure, reference numeral 6a denotes an oil hole, 7a a discharge hole, 9 a discharge muffler, and 110a a through hole.
상기와 같은 본 발명에 의한 압축기의 진동 저감 장치는 다음과 같은 작용효과가 있다.The vibration reduction device of the compressor according to the present invention as described above has the following effects.
즉, 전동기구부에 전원을 인가하여 회전자(3)가 회전하면, 회전자(3)와 함께 회전축(6)이 회전하면서 롤링피스톤(8)을 편심 회전시켜 냉매가스를 실린더(5)의 밀폐공간으로 흡입하여 압축 토출시키는 일련의 과정을 반복한다.That is, when the rotor 3 rotates by applying power to the electric mechanism, the rotating shaft 6 rotates together with the rotor 3 to eccentrically rotate the rolling piston 8 to seal the refrigerant gas in the cylinder 5. A series of processes of suction and compression discharge into the space are repeated.
이때, 회전축(6)이 편심부를 구비하여 회전하면서 불평형 질량에 의한 가진력을 발생하고 이 가진력에 의해 회전자(3)가 비스듬히 기울어져 회전하면서 고정자(2)와 충돌할 우려가 있으나, 이 불평형 질량에 의한 규칙적인 가진력은 회전자(3)의 양측에 결합한 밸런스 웨이트(4A,4B)에 의해 일정정도 감쇠하면서 회전자(3)가 보다 안정되게 회전할 수 있다.At this time, the rotating shaft 6 is provided with an eccentric portion to generate an excitation force due to an unbalanced mass, and by this excitation force, the rotor 3 may be inclined obliquely to rotate and collide with the stator 2. The regular excitation force by the rotor 3 can rotate more stably while decaying to some extent by the balance weights 4A and 4B coupled to both sides of the rotor 3.
또, 회전자(3)를 비롯한 회전축(6)이 회전하면서 냉매가스를 압축함에 따라 가스력에 의한 가진력이 회전축(6)으로 전달되어 회전축(6)은 특정한 고유진동수를 갖게 되나, 회전축(6)의 하단에 장착한 본 발명의 동흡진기(100)가 회전축(6)의 고유진동수를 흡수하여 상쇄하므로 불평형 질량에 의한 규칙적인 가진력은 물론 가스력에 의한 불규칙적인 가진력도 함께 감쇠할 수 있고 이를 통해 회전축(6)의 회전시 발생하는 진동이 케이싱(1)의 외부로 전달하는 것을 방지하여 압축기의 신뢰성을 향상할 수 있다.In addition, as the rotating shaft 6 including the rotor 3 rotates to compress the refrigerant gas, the excitation force due to the gas force is transmitted to the rotating shaft 6 so that the rotating shaft 6 has a specific natural frequency, but the rotating shaft 6 Since the copper reducer 100 of the present invention mounted on the lower part of the present invention absorbs and offsets the natural frequency of the rotating shaft 6, it can attenuate the regular excitation force due to the unbalanced mass as well as the irregular excitation force due to the gas force. The vibration generated during the rotation of the rotary shaft 6 can be prevented from being transmitted to the outside of the casing 1, thereby improving the reliability of the compressor.
참고로, 이러한 동흡진기는 전술한 일실시예에서와 같은 로터리 압축기는 물론 왕복동식이나 스크롤과 같이 회전체를 갖는 압축기에 다양하게 적용할 수 있다.For reference, such a copper reducer may be variously applied to a rotary compressor as in the above-described embodiment as well as a compressor having a rotating body such as a reciprocating type or a scroll.
본 발명에 의한 압축기의 진동 저감 장치는, 회전자에 밸런스 웨이트를 장착함과 아울러 회전축에 탄성부와 질량부를 갖는 동흡진기로 장착하여 구성함으로써, 회전축의 불평형 질량에 의한 가진력은 물론 회전축의 특정한 고유진동수를 흡수하여가스력에 의한 가진력도 함께 감쇠할 수 있어 회전체를 갖는 압축기에서의 진동을 효과적으로 줄일 수 있다.The vibration reduction device of the compressor according to the present invention is configured by mounting a balance weight on a rotor and a dynamic reducer having an elastic part and a mass part on the rotating shaft, so that the excitation force caused by the unbalanced mass of the rotating shaft as well as the specific inherent of the rotating shaft By absorbing the frequency can also attenuate the excitation force due to the gas force can effectively reduce the vibration in the compressor having a rotating body.
