Description

선형압축기의 모터구조Motor structure of linear compressor

본 고안은 선형압축기에 관한 것으로서, 특히 모터부의 제작시 부품 취부위치의 기준을 명확히 하고 고정을 확실이 하여 철심의 진원도, 원통도를 향상하고 공극을 최소화 시키는등 작업공정의 신뢰성을 개선하기 위한 모터부구조에 관한 것이다.The present invention relates to a linear compressor, in particular, the motor for improving the reliability of the work process, such as to improve the roundness, cylinder degree and minimize the air gap of the core by clarifying and fixing the standard of the parts mounting position when manufacturing the motor part It is about substructure.

종래 선형압축기모터는 도 1 및 도 2 에 도시된 바와같이 내부철심(6)은 전기강판을 방사형으로 적층하여 원통형으로 만들어 용접(9)하고, 그 내부에 얇은 절연지로 절연처리한 후 코일(5)을 감았으며, 인너케이스(2) 내측면에 결합되는 외부철심(1)은 내부철심(6)과 같이 전기강판을 방사형으로 적층하여 원통형으로 만들고 용접(9)하여 가조립하고, 인너케이스(2)의 내측면에는 외부철심(1)의 양단에 링(3)을 각각 결합시킨후 돌기(2')에 의해 지지되도록 조립한다.In the conventional linear compressor motor, as shown in FIGS. 1 and 2, the inner core 6 is formed by radially stacking electrical steel sheets to form a cylindrical shape, welded 9, and insulates with a thin insulating paper therein, and then coils 5. ), And the outer iron core (1) coupled to the inner surface of the inner case (2) is laminated with electrical steel sheets radially like the inner iron core (6), cylindrically welded (9), and preassembled, and the inner case (2). On the inner side of the coupling ring (3) to each end of the outer iron core (1) and then assembled so as to be supported by the projection (2 ').

그리고 상기 내부철심(6)과 외부철심(1) 사이에는 좌우이동이 가능한 영구자석(4)이 조립되며, 쉘의 중심에는 피스톤(7)이 위치하게 된다.Then, between the inner core 6 and the outer core (1) is assembled a permanent magnet (4) that can move left and right, the piston (7) is located in the center of the shell.

이와같이 구성되는 종래 선형압축기모터는 코일(5)에 흐르는 전류에 의해 자장이 발생되고, 내부철심(6)에서 유기된 자장과 영구자석(4)간의 자기력에 의해 영구자석(4)이 좌우로 왕복운동을 한다. 이때 영구자석(4)에 연결된 피스톤(7)이 왕복운동을 하여 헤드부(8)에서 냉매를 흡입,토출한다.In the conventional linear compressor motor configured as described above, a magnetic field is generated by a current flowing in the coil 5, and the permanent magnet 4 reciprocates from side to side by a magnetic force between the magnetic field induced at the inner core 6 and the permanent magnet 4. work out. At this time, the piston 7 connected to the permanent magnet 4 reciprocates to suck and discharge the refrigerant from the head portion 8.

그러나 종래의 구조중 외부철심(1)은 전기강판을 방사형으로 적층하여 원통형으로 되어 명확하게 잡아줄 수 있는 것이 없어 진원도, 원통도를 내는데 한계가 있으며, 그에 따라 공극은 크게 설계할 수 밖에 없어 재료비가 높아지는 결과를 초래한다. 또 진원도, 원통도를 일정수준으로 내기위해 외부철심에 닿는 부분의 링(3)을 삼각형으로 가공하여 잡아주므로서 가공비가 증가되는 등의 문제점이 있었다.However, in the conventional structure, the outer core 1 has a circular shape and a cylindrical shape that can be clearly grasped by stacking electrical steel sheets radially, and thus, there is a limit in producing roundness and cylinder degree. Results in an increase. In addition, there was a problem that the processing cost is increased by holding the ring (3) of the part touching the outer iron core in a triangle in order to give a roundness, cylindrical degree to a certain level.

본 고안은 이러한 점을 해결하기 위하여 외부철심이 결합되는 인너케이스 양단을 내측으로 구부려서 외부철심을 고정시키고, 외부철심에 요홈을 두고 홈에 링을 압입하여 방사형으로 적층시킴으로서, 제품의 제작공정을 단순화하여 가공비 및 재료비를 절감시키도록 하는데 목적이 있다.In order to solve this problem, the present invention is to bend both ends of the inner case to which the outer core is coupled to fix the outer core, and to simplify the manufacturing process of the product by pressing the groove into the groove and radially laminating the groove. The purpose is to reduce the processing costs and material costs.

본 고안을 도 3 내지 도 5 를 참조하여 이하에서 상세히 설명한다.The present invention will be described in detail below with reference to FIGS.

먼저 구성을 살펴보면 인너케이스(102)의 내측면에 외부철심(101)이 결합되고, 상기 외부철심(101)과 내부철심(106)의 사이에 좌우 유동이 가능한 영구자석(104)이 결합되는 선형압축기모터에 있어서, 외부철심(101)이 결합되는 인너케이스(102) 양단(102')을 내측으로 구부려서 외부철심(101)을 고정시키고, 상기 외부철심(101)의 양단에 요홈(100)을 두고 홈(100)에 링(103)을 압입하여 방사형으로 적층시킴으로 구성이 완성된다.Looking at the configuration first, the outer iron core 101 is coupled to the inner surface of the inner case 102, the linear permanent magnet 104 is coupled between the outer iron core 101 and the inner iron core 106 is possible In the compressor motor, the inner case (102) of the inner case 102 to which the outer iron core 101 is coupled is bent inward to fix the outer iron core (101), and the grooves (100) are provided at both ends of the outer iron core (101). The configuration is completed by pressing the ring 103 in the groove 100 and radially stacking the same.

도면중 미설명 부호 105 는 코일을 나타낸다.In the figure, reference numeral 105 denotes a coil.

이와같이 구성되는 본 고안의 모터부 제작 공정시 먼저 외부철심(101)을 압입한 후 좌측 인너 케이스 돌기(102')와 좌측 인너 케이스 끝단부를 기준으로 우측 인너 케이스 돌기(102')를 구부려 고정시키게 된다.In the process of manufacturing the motor unit of the present invention configured as described above, the external inner core 101 is first press-fitted and then fixed by bending the right inner case protrusion 102 'based on the left inner case protrusion 102' and the left inner case end. .

이때, 외부철심(101)은 전기강판을 방사형으로 적층하면서 타발한 링(103)을 압입하여 자연스럽게 진원도, 원통도가 나와 종래의 용접(9), 링(3)의 역할을 하여 공정이 단순해지게 되는 것이다.At this time, the outer core 101 is pressed into the punched ring 103 while laminating the electrical steel sheet radially, naturally roundness, cylindrical degree came out to act as a conventional welding (9), ring (3), the process is simple You lose.

이상 설명한 바와같이 본 고안의 모터부구조는 제품의 가공비가 절감되며, 정도(精度)가 향상되어 종래와 동등의 특성을 내면서 크기를 줄여 재료비를 절감하고, 외부철심을 인너케이스의 돌기로 고정함으로 후공정을 단순하게 하는등의 효과가 있다.As described above, the motor part structure of the present invention reduces the processing cost of the product, improves the precision, reduces the size by reducing the size while having the same characteristics as the conventional one, and fixes the external core by the projection of the inner case. The effect is to simplify the post process.
