Description

차량용 발전기{Operator for vehicle}Generator for vehicle

본 발명은 차량용 발전기에 관한 것으로, 보다 상세하게는 유냉식 냉각장치를 구비한 차량용 발전기에 관한 것이다.The present invention relates to a vehicle generator, and more particularly to a vehicle generator having an oil-cooled cooling device.

일반적으로, 소형 차량 등에 설치되는 발전기는 그 구동열을 냉각시키기 위해 주로 공냉식 냉각장치를 채용한다. 그런데, 전투차량과 같은 특수차량에 탑재되는 대용량의 발전기는 그 발전기의 구동열이 많기 때문에 공냉식 냉각장치만을 이용하여서는 효과적인 냉각효율을 얻기가 매우 힘들다Generally, a generator installed in a small vehicle or the like mainly adopts an air-cooled cooling device to cool its driving heat. However, since a large-capacity generator mounted on a special vehicle such as a combat vehicle has a lot of driving heat of the generator, it is very difficult to obtain effective cooling efficiency only by using an air-cooled cooling system.

특히, 발전기에서 발생되는 주요 열은 발전기 내부에 설치되는 정류소자 및 코일 등으로부터 기인하는 것이 대부분이므로, 발전기 내부의 열을 직접적으로 냉각시킬 수 있는 유냉식 냉각장치가 절실히 요구된다.In particular, since the main heat generated from the generator is mostly due to the rectifier and coils installed in the generator, there is an urgent need for an oil-cooled cooling apparatus capable of directly cooling the heat inside the generator.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 유냉식 냉각장치가 구비된 차량용 발전기를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and an object thereof is to provide a generator for a vehicle equipped with an oil-cooled cooling device.

It is provided with a rear cover 15. Here, the front cover 13 is formed with an oil inlet 13a through which oil for cooling the driving heat of the generator flows, and an oil outlet 13b for extracting oil recovered in the housing 10 to the outside. .

상기 회전축(20)은 전면커버(13)와 후면커버(15) 각각에 회전가능하게 지지되어 있다. 그리고, 이 회전축(20)에는 상기 회전자(30)가 결합되어 있다. 상기 회전자(30)는 회전축(20)과 함께 회전되는 것으로, 메인회전자(main rotor; 31)와 여자 회전자(field rotor; 33)로 이루어진다. 또한, 상기 고정자(40)는 회전자(30)의 외측에 위치되도록 하우징(10) 내벽에 설치된다. 이러한 고정자(40)는 메인회전자(31)에 대응되는 메인고정자(main stator; 41)와, 여자회전자(33)에 대응되는 여자고정자(field stator; 43)로 이루어진다. 또한, 상기 하우징(10) 내부의 후면커버(15)에 인접부위에는 상기 정류소자(50)가 설치되어 있다.The rotating shaft 20 is rotatably supported by each of the front cover 13 and the rear cover 15. The rotor 30 is coupled to the rotary shaft 20. The rotor 30 is rotated together with the rotation shaft 20, and is composed of a main rotor 31 and a field rotor 33. In addition, the stator 40 is installed on the inner wall of the housing 10 to be located outside the rotor 30. The stator 40 includes a main stator 41 corresponding to the main rotor 31 and a field stator 43 corresponding to the excitation rotor 33. In addition, the rectifying element 50 is installed at an adjacent portion of the rear cover 15 in the housing 10.

상기 오일냉각 시스템은 상기 오일유입구(13a)로 유입되는 오일의 일부를 하우징(10)의 중심에서 내벽쪽으로 분사시키기 위한 제1분사경로(61)와, 오일유입구(13a)로 유입되는 오일의 일부를 하우징(10)의 내벽에서 중심부 및 정류소자(50)쪽으로 분사시키기 위한 제2분사경로(63)와 하우징(10) 내부의 바닥과 상기 오일유출구(13b)를 연결하는 오일 회수경로(65) 및 회수펌프(67)를 구비한다.The oil cooling system includes a first injection path 61 for injecting a part of the oil flowing into the oil inlet 13a from the center of the housing 10 toward the inner wall, and a part of the oil flowing into the oil inlet 13a. Oil recovery path (65) connecting the second injection path (63), the bottom of the housing (10), and the oil outlet (13b) to inject the air from the inner wall of the housing (10) to the center and the rectifying element (50). And a recovery pump 67.

상기 제1분사경로(61)는 오일유입구(13a)에 연통되도록 회전축(20)에 길이방향으로 형성된 축공(61a)과, 이 축공(61a)에 연통되도록 회전축(20)의 외주에 소정 간격으로 형성된 복수의 분사구(61b)로 이루어진다. 상기 축공(61a)은 전면커버(13)에 결합되는 단부쪽으로부터 개방되어 그 반대쪽 단부는 막힌 구조를 갖는다. 그리고, 상기 분사구(61b)는 회전축(20)의 외주 방향으로 소정 간격으로 복수개가 형성되며, 고압으로 분사될 수 있도록 축공(61a)보다 상대적으로 작은 직경을 갖는다. 또한, 분사구(61b)는 회전축(20)의 길이방향으로도 소정 간격으로 형성되는 것이 바람직하다.The first injection path 61 has a shaft hole (61a) formed in the longitudinal direction on the rotary shaft 20 to communicate with the oil inlet (13a), and at a predetermined interval on the outer periphery of the rotary shaft 20 to communicate with the shaft hole (61a) It consists of a plurality of injection holes (61b) formed. The shaft hole 61a is opened from an end side coupled to the front cover 13 so that the opposite end thereof is blocked. In addition, the injection holes 61b are formed in plural at predetermined intervals in the outer circumferential direction of the rotation shaft 20, and have a diameter smaller than that of the shaft hole 61a so as to be injected at a high pressure. In addition, the injection port 61b is preferably formed at predetermined intervals in the longitudinal direction of the rotation shaft 20.

상기 제2분사경로(63)는 오일유입구(13a)에 연통되도록 하우징(10)의 몸체 내부에 형성된 오일관로(63a)와, 오일관로(63a)에 연통되도록 하우징(10) 내벽에 소정 간격으로 형성된 분사노즐(63b)을 구비한다. 상기 오일관로(63a)는 구체적으로, 상기 전면커버(13)에서부터 외주몸체(11)에 이르기까지 연장형성된다. 따라서, 전면커버(13)를 외주몸체(11)에 결합시 연통된다. 또한, 상기 분사노즐(63)은 외주몸체(11)의 내벽에 돌출되게 형성된다. 따라서, 오일관로(63a)를 통해 유입된 오일은 분사노즐(63b)을 통해 하우징(10) 내부로 분사된다. 이 분사노즐(63b)의 직경도 오일관로(63a)보자 작은 것은 당연하며, 하우징(10)의 내벽에 복수개가 형성될 수 있다. 또한, 상기 오일관로(63a)의 끝부분은 정류소자(50)로 오일을 분사할 수 있도록 그 정류소자(50)에 인접부위까지 연장되어 있다.The second injection path 63 is an oil pipeline 63a formed inside the body of the housing 10 so as to communicate with the oil inlet 13a, and the inner wall of the housing 10 at predetermined intervals so as to communicate with the oil pipeline 63a. The injection nozzle 63b formed is provided. Specifically, the oil pipe line 63a extends from the front cover 13 to the outer circumferential body 11. Therefore, the front cover 13 is in communication with the outer peripheral body 11 when coupled. In addition, the injection nozzle 63 is formed to protrude to the inner wall of the outer peripheral body (11). Therefore, the oil introduced through the oil pipeline 63a is injected into the housing 10 through the injection nozzle 63b. It is obvious that the diameter of the injection nozzle 63b is smaller than that of the oil pipe 63a, and a plurality of the injection nozzles 63b may be formed on the inner wall of the housing 10. In addition, the end of the oil pipe (63a) is extended to the adjacent portion to the rectifying device 50 so that the oil can be injected into the rectifying device (50).

상기 회수경로(65)는 상기 제1 및 제2분사경로(61)(63)를 통해 하우징(10) 내로 유입된 후 하우징(10) 바닥에 고인 오일을 외부로 유출해낼 수 있도록, 하우징(10)의 바다부분에서 전면커버(13)에 걸쳐 형성되어 있다. 또한, 이회수경로(65) 상에는 상기 회수펌프(67)가 설치되어 있다. 구체적으로, 회수펌프(67)는 하우징(10) 내에 고인 오일을 강제펌핑하기 위한 것으로, 전면커버(13)에 설치된다.The recovery path 65 flows into the housing 10 through the first and second injection paths 61 and 63 and then flows out of oil accumulated in the bottom of the housing 10 to the outside. Is formed over the front cover (13) in the sea portion of. In addition, the recovery pump 67 is provided on the recovery path 65. Specifically, the recovery pump 67 is for forcibly pumping oil accumulated in the housing 10, and is installed in the front cover 13.

이하 오일을 이용한 발전기의 냉각방법을 설명하기로 한다.Hereinafter, a cooling method of a generator using oil will be described.

발전기가 구동되면, 주로 회전자(30)와 고정자(40) 및 정류소자(50)에서 많은 열이 발생된다. 따라서, 발전기의 구동시 하우징(10) 외부의 소정 오일고급부(미도시)로부터 오일유입구(13a)로 냉각용 오일이 공급된다. 공급된 오일의 일부는 축공(61a)으로 유입되어 분사구(61b)로 분사된다. 이 때, 회전축(20)이 회전되는 상태이고, 분사구(61b)에서 분사압이 높아지므로 하우징(10) 내부로 분사되는 오일은 고압으로 분사된다. 따라서, 분사되는 오일은 하우징(10) 내부에 골고루 퍼짐으로써 회전자(30) 및 고정자(40)를 냉각시키게 된다. 특히 회전자(30)의 철심 및 코일 등에 오일이 직접 분사되므로 회전자에서 발생되는 열을 효과적으로 제거한다. 이와 같이 분사된 오일은 하우징(10) 바닥으로 떨어져서 고인다.When the generator is driven, a large amount of heat is generated mainly in the rotor 30, the stator 40 and the rectifier 50. Therefore, the cooling oil is supplied to the oil inlet 13a from a predetermined oil advanced part (not shown) outside the housing 10 when the generator is driven. A part of the supplied oil flows into the shaft hole 61a and is injected into the injection hole 61b. At this time, since the rotary shaft 20 is rotated and the injection pressure is increased at the injection port 61b, the oil injected into the housing 10 is injected at a high pressure. Therefore, the injected oil is evenly spread in the housing 10 to cool the rotor 30 and the stator 40. In particular, since oil is directly injected to the iron core and the coil of the rotor 30, the heat generated from the rotor is effectively removed. The oil sprayed in this way falls to the bottom of the housing 10 and accumulates.

한편, 오일유입구(13a)로 유입된 후 오일관로(63a)로 진입된 오일은 하우징(10)에 설치된 고정자(40)의 열을 1차로 냉각시킨다. 이어서, 오일은 분사노즐(63b)을 통해 하우징(10) 내벽으로부터 하우징(10) 내부의 중앙쪽으로 분사된다. 이와 같은 분사된 오일은 주로 고정자(40)에 직접 분사되어 열을 제거한 후 하우징(10) 바닥으로 떨어진다. 또한, 오일관로(63a)로 공급되는 오일의 일부는 정류소자(50)로 분사된다. 따라서, 정류소자(50)도 직접 분사된 오일에 의해 열이 효과적으로 제거된다. 이 정류소자(50)에 분사된 오일도 하우징(10) 바닥으로 떨어진다.On the other hand, the oil introduced into the oil inlet (13a) and then enters the oil pipeline (63a) cools the heat of the stator 40 installed in the housing 10 first. The oil is then injected from the inner wall of the housing 10 through the injection nozzle 63b toward the center of the inside of the housing 10. The injected oil is mainly sprayed directly on the stator 40 to remove heat and fall to the bottom of the housing 10. In addition, a part of the oil supplied to the oil pipe line 63a is injected into the rectifier 50. Therefore, the rectifier 50 is also effectively removed heat by the oil directly injected. The oil injected into the rectifier 50 also drops to the bottom of the housing 10.

한편, 하우징(10) 바닥에 떨어져서 고인 오일은 회수펌프(67)의 구동력에 의해 펌핑되어 회수경로(65)를 통해 하우징(10) 외부로 배출된다. 그리고, 배출된 오일은 소정 냉각장치(미도시)에서 냉각되어 오일탱크에 저장되었다가 다시 오일유입구(13a)로 공급된다.On the other hand, the oil accumulated on the bottom of the housing 10 is pumped by the driving force of the recovery pump 67 is discharged to the outside of the housing 10 through the recovery path (65). The discharged oil is cooled in a predetermined cooling device (not shown), stored in the oil tank, and supplied to the oil inlet 13a.

이상에서 설명한 바와 같은 본 발명에 따른 차량용 발전기에 따르면, 발전기의 주요 열 발생부분인 고정자, 회전자 및 정류소자 의 각부분에 오일을 고르게 직접 공급함으로써 발전기의 냉각성능을 극대화 할 수 있다. 그리고, 하우징과 회전축 자체에 오일 공급경로를 일체로 형성함으로써 발전기의 경량화 및 소형화가 가능하게 된다.According to the vehicle generator according to the present invention as described above, by directly supplying the oil evenly to each part of the stator, the rotor and the rectifying element which is the main heat generating portion of the generator can maximize the cooling performance of the generator. In addition, since the oil supply path is integrally formed in the housing and the rotating shaft itself, the generator can be reduced in weight and size.
