본 고안은 진공청소기용 전동기의 베어링 지지장치에 관한 것으로서, 특히 진공청소기 내에 그 설치를 용이하게 하고 그 설치상태에서 공회전과 소음을 방지할 수 있도록 개량한 진공청소기용 모터에 베어링 지지장치에 관한 것이다.The present invention relates to a bearing support device for a vacuum cleaner electric motor, and more particularly, to a bearing support device for a vacuum cleaner motor improved to facilitate its installation in a vacuum cleaner and to prevent idle and noise in the installation state. .
일반적으로 진공청소기용 전동기는 높은 진공도를 얻기 위해 고마력으로 고속회전하도록 설계되고 있다. 따라서 진공청소기용 전동기는 진공청소기 내에서 안정된 설치구조가 요구되는 것은 물론, 고속회전시에 발생되는 이상소음을 방지할 수 있도록 배려할 필요가 있는 것이다.In general, the motor for the vacuum cleaner is designed to rotate at high horsepower at high horsepower to obtain a high degree of vacuum. Therefore, the motor for the vacuum cleaner is required to consider a stable installation structure in the vacuum cleaner as well as to prevent abnormal noise generated during high-speed rotation.
제1도는 통상의 진공청소기를 나타낸다. 여기서 진공청소기용 전동기(M)는 전방의 흡기날개 덮개(IC)와 후방의 몸체(H)로 외관을 이루며, 흡기날개(IC)의 모서리와 몸체(H)에 돌출된 베어링 지지부(B)가 진공청소기 본체(VC)내에 형성된 지지벽(R, R′)에 지지되도록 설치된다.1 shows a conventional vacuum cleaner. Here, the vacuum motor (M) has an appearance with the front intake wing cover (IC) and the rear body (H), the bearing support (B) protruding from the corner and the body (H) of the intake wing (IC) It is installed so as to be supported by the support walls R and R 'formed in the vacuum cleaner main body VC.
이러한 설치구조에 있어서, 종래에는 제2도와 같이, 전동기 몸체(1)의 베어링 지지부(2)를 원통형으로 형성하였는데, 이 부위를 그대로 지지체(3, 3′)에 지지시킬 경우, 고속회전시 진공청소기 본체내에서의 전동기 전체의 공회전이 유발될 수 있고, 이에 따른 이상소음이 발생하게 된다. 따라서 종래에는 도면에 나타낸 바와 같이 그 베어링 지지부(2) 주위에 씌워지고 지지체(3, 3′) 사이에 꼭 끼이는 고무재 보호구(4)를 구비하였던 것이다.In this installation structure, in the past, as shown in FIG. 2, the bearing support 2 of the motor body 1 is formed in a cylindrical shape. When this part is supported by the supports 3 and 3 'as it is, the vacuum at high rotation speed is performed. Idle of the entire motor in the cleaner body may be induced, thereby causing abnormal noise. Therefore, in the related art, as shown in the drawing, the rubber protective device 4 is provided around the bearing support 2 and tightly sandwiched between the supports 3 and 3 '.
즉, 종래에는 진공청소기용 전동기의 설치에 있어서, 별도의 부품을 추가 사용하여야 하는 구조적 단점 때문에, 부품증가에 따른 조립공수 증가와 원가상승의 문제점이 있는 것이다. 더욱이 상기한 보호구는 그 공회전과 이상소음을 일시적으로 방지할 수는 있으나 장시간 경과하면 그 역할을 제대로 수행할 수 없게 된다.That is, conventionally, in the installation of the vacuum cleaner motor, due to the structural disadvantage that additional parts must be used additionally, there is a problem of an increase in the number of assembly operations and the cost increase according to the increase of parts. Moreover, the above-mentioned protective equipment can temporarily prevent the idle and abnormal noise, but after a long time, it cannot perform its role properly.
따라서 본 고안의 목적은 상기한 문제점을 감안하여 별도의 부품을 추가 사용하지 않고도 설치가 용이하고 항구적인 공회전 및 이상소음 방지를 위해 개량된 진공청소기용 전동기의 베어링 지지장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a bearing support device for an improved vacuum cleaner motor for easy installation and preventing permanent idle and abnormal noise without using additional parts in view of the above problems.
이러한 목적을 달성하는 본 고안의 진공청소기용 전동기의 베어링 지지장치는, 소정의 두께로 되고 베어링의 외륜이 지지되는 내경부를 가지는 원통부와, 소정의 두께로 되고 상기 원통부에 외접하는 각형부를 가지며, 상기 원통부와 상기 각형부의 각 모퉁이 사이에 공간부가 형성되어 있는 것을 그 특징으로 한다.The bearing support apparatus of the vacuum cleaner electric motor of the present invention which achieves such an object has a cylindrical portion having an inner diameter portion having a predetermined thickness and supported by an outer ring of the bearing, and a rectangular portion having a predetermined thickness and circumscribing the cylindrical portion. And a space portion is formed between each of the corners of the cylindrical portion and the square portion.
이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도에 도시된 본 고안 실시예에 있어서, 전동기 몸체(10)의 베어링 지지부(20)는 원통부(21)와 이 원통부(21)에 회접하는 4각형의 각형부(22)를 가진다. 이에 대한 전술한 진공청소기의 본체 내에 형성되는 지지체(30, 30′) 역시, 상기 각형부(22)의 둘레에 꼭 맞는 4각형을 이루는 홈부(31, 31′)를 갖는다.In the embodiment of the present invention shown in FIG. 3, the bearing support 20 of the electric motor body 10 has a cylindrical portion 21 and a quadrilateral square portion 22 which is in contact with the cylindrical portion 21. . The support bodies 30 and 30 'formed in the main body of the vacuum cleaner described above also have groove portions 31 and 31' which form a quadrangular shape that fits perfectly around the square portion 22.
제4도를 참조하면, 베어링 지지부(20)의 원통부(21)는 소정 직경의 내경부(23)를 가진다. 또한 원통부(21)와 각형부(22)의 각 모퉁이 사이에 공간부(24)들이 형성되어 있다. 여기서 원통부(21)의 내경부(23)에는 내륜(부호생략)에 끼워져 결합된 회전축(11)을 지지하는 베어링(12)의 외륜(부호생략)이 지지된다. 한편, 전동기의 베어링 지지부(20)는 그 각형부(22)가 지지체(30, 30′)에 끼워짐으로써 진공청소기 본체내에 설치된다.Referring to FIG. 4, the cylindrical portion 21 of the bearing support 20 has an inner diameter 23 of a predetermined diameter. In addition, the spaces 24 are formed between the corners of the cylindrical portion 21 and the square portion 22. Here, the inner ring 23 of the cylindrical portion 21 is supported by the outer ring (not shown) of the bearing 12 supporting the rotating shaft 11 coupled to the inner ring (not shown). On the other hand, the bearing support part 20 of an electric motor is provided in the vacuum cleaner main body by the square part 22 being fitted in the support body 30 and 30 '.
이러한 본 고안에 의하면, 상기한 베어링 지지부(20)는 4각형 각형부(22)에 의하여 지지체(30, 30′)의 홈부(31, 31′)내에 공회전할 수 없음은 당연하다. 또한 원통부(21)와 각형부(22)의 각 모퉁이 사이에 형성되어 있는 공간부(24)가 그 부근의 원통부(21)와 각형부(22)의 신축을 탄력있게 허용하는 완충작용을 하게 되므로, 고속회전시의 베어링(12) 마찰에 의한 이상소음이나 어떤 충격을 흡수한다.According to the present invention, it is obvious that the bearing support portion 20 cannot be idle in the groove portions 31 and 31 'of the supports 30 and 30' by the quadrilateral square portion 22. In addition, the space portion 24 formed between the corners of the cylindrical portion 21 and the square portion 22 has a buffering action to allow elasticity of the cylindrical portion 21 and the square portion 22 in the vicinity thereof. Therefore, abnormal noise and any shock caused by friction in the bearing 12 during high speed rotation are absorbed.
즉, 본 고안에 따른 진공청소기용 전동기의 베어링 지지장치에 의하면, 전동기를 진공청소기 본체내에 설치함에 있어서, 전동기 자체의 공회전이 방지되고 또한 이상소음이 발생하는 문제점이 간단히 해결될 수 있다.That is, according to the bearing support device of the vacuum cleaner electric motor according to the present invention, in installing the electric motor in the vacuum cleaner main body, the problem that the idling of the motor itself is prevented and abnormal noise occurs can be easily solved.
아울러, 본 고안은 진공청소기용 전동기의 설치를 위해 부품을 추가하지 않아도 되므로 부품감소에 따른 조립공수와 원가상승을 방지하는 경제적 잇점을 제공하고, 특히 전동기의 공회전 방지 및 이상소음 억제를 통해 진공청소기의 품질향상에도 기여하는 효과적인 고안이다.In addition, the present invention does not need to add parts for the installation of the vacuum cleaner motor, and thus provides an economical advantage of preventing assembly labor and cost increase due to the reduction of parts, and in particular, vacuum cleaner by preventing the idling of the motor and suppressing abnormal noise It is an effective design that also contributes to quality improvement.
