본 고안은 청소기용 모터의 볼 베어링(Ball Bearing)부 브러쉬분진 방지장치에 관한 것으로 보다 상세하게로는, 청소기용 모터의 하우징상측에 설치되어 모터축의 회전에 구름운동을 하는 볼베어링부 하측으로 중앙에 모터축 삽입홀이 천설되고, 모터축 삽입홀 주연에 단턱이 입설된 오목형 분진침투방지와셔(washer)를 설치함으로써, 정류자 모터에서 발생되는 브러쉬분진의 볼베어링부 침투를 유효하게 차단시키며, 이로인한 모터의 수명을 연장시킬 수 있도록 한 청소기용 모터의 볼 베어링부 브러쉬분진방지장치에 관한 것이다.The present invention relates to a brush dust prevention device of a ball bearing part of a cleaner motor. More specifically, the present invention relates to a brush dust prevention device of a cleaner motor. The motor shaft insertion hole is installed, and by installing the concave dust penetration preventing washer with the stepped end around the motor shaft insertion hole, it effectively blocks the penetration of the ball bearing part of the brush dust generated from the commutator motor. The present invention relates to a brush dust prevention device of a ball bearing part of a cleaner motor, which can extend the life of the motor.
일반적으로 청소기용 모터(1)는 제1도에 도시한 바와같이, 하우징(2)내부에는 중앙 상하측으로 모터축(3)이 연장설치되고, 상기 모터축(3)의 회전에 대해 구름운동을 수행하는 볼 베어링부(4)가 마련된다.In general, as shown in FIG. 1, the cleaner motor 1 has a motor shaft 3 extending upward and downward in the center of the housing 2, and performs rolling motion with respect to the rotation of the motor shaft 3. A ball bearing portion 4 is provided.
따라서, 청소기용 모터(1)의 가동에 의해 모터에서 발생되는 브러쉬분진의 흡입시 공기의 역류에 의해 볼 베어링부(4)의 내륜으로 상기 분진이 침투하여 베어링의 마모를 촉진시키고, 이로인한 모터의 수명을 단축시키게 되는 문제점이 있었던 것이다.Therefore, the dust penetrates into the inner ring of the ball bearing part 4 by the reverse flow of air when suctioning the brush dust generated by the motor by the operation of the cleaner motor 1, thereby promoting the wear of the bearing, and thus the motor There was a problem that will shorten the life of.
한편, 제2도에 도시한 바와같이, 종래의 모터축(3)회전에 따라 구름운동을 하는 볼 베어링부(4)하측에는, 모터축(3)에 요홈(3a)을 형성하고, 상기 요홈(3a)내에 일측이 개구된 C-링(Ring)(11)을 삽입고정하여 모터(1)에서 발생되는 브러쉬 분진의 볼베어링부(4)침투를 차단시키는 구조로 이루어졌다.On the other hand, as shown in FIG. 2, the groove 3a is formed in the motor shaft 3 below the ball bearing part 4 which performs rolling motion according to the rotation of the conventional motor shaft 3, and the said groove The C-ring (11) having one side opened in (3a) was fixed to block the penetration of the ball bearing portion 4 of the brush dust generated from the motor 1.
그러나, 상기와같이 모터축(3)에 C-링(11)을 삽입하여 분진을 차단시킨다하여도, C-링(11)의 일측 개구부를 통하여 브러쉬분진이 볼 베어링부(4)로 침투됨은 물론, 상기 C-링(11)은 원판상으로 구성됨으로써, 볼 베어링부(4)와의 마찰시 쉽게 마모가 발생되며, 모터축(3)의 요홈(3a)에서 쉽게 이탈되는등 많은 문제점이 있었던 것이다.However, even when the dust is blocked by inserting the C-ring 11 into the motor shaft 3 as described above, the brush dust penetrates into the ball bearing part 4 through one side opening of the C-ring 11. Of course, since the C-ring 11 is formed in a disk shape, wear occurs easily when friction with the ball bearing part 4, and there are many problems such as being easily detached from the groove 3a of the motor shaft 3. will be.
본 고안은 상기한 바와같은 종래의 제반문제점들을 개선하기 위하여 안출된 것으로서 그 목적은, 청소기용 모터의 하우징상측에 설치되어 모터축의 회전에 구름운동을 하는 볼베어링부 하측으로 중앙에 모터축 삽입홀이 천설되고, 모터축 삽입홀 주연에 단턱이 입설된 오목형 분진침투방지와셔(washer)를 설치함으로써, 정류자 모터에서 발생되는 브로쉬분진의 볼 베어링부 침투를 유효하게 차단시키며, 이로인한 모터의 수명을 연장시킬수 있도록 한 청소기용 모터의 볼 베어링부 브러쉬분진방지장치를 제공하는데 있다.The present invention has been made in order to improve the conventional problems as described above, the purpose of which is installed on the housing of the motor for the cleaner, the motor shaft insertion hole in the center to the lower side of the ball bearing portion rolling the rotation of the motor shaft By installing a concave dust penetration preventive washer installed at the periphery of the motor shaft insertion hole, it effectively blocks the penetration of the ball bearing part of the brush dust generated from the commutator motor, thereby resulting in a long service life of the motor. To provide a brush dust prevention device of the ball bearing part of the cleaner motor to extend the.
이하, 첨부된 도면에 의거하여 본 고안의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 청소기용 모터의 볼 베어링부 브러쉬분진방지장치를 설명하기위한 분진침투방지와셔의 사시도 및 제4도는 제3도의 정단면도로서, 청소기용 모터(1)의 하우징(2)상측에 설치되어 모터축(3)의 회전에 구름운동을 수행하는 볼 베어링부(4)하측으로, 중앙에 모터축 삽입홀(5)이 천설되고, 모터축 삽입홀(5)주연에는 단턱(6)이 입설된 오목형 분진침투방지와셔(7)가 설치되어 모터(1)에서 발생되는 브러쉬분진을 차단토록하는 구성으로 이루어진다.FIG. 3 is a perspective view of a dust penetration preventing washer for explaining the ball bearing part brush dust prevention device of the cleaner motor according to the present invention, and FIG. 4 is a front sectional view of FIG. 3, and the housing 2 of the cleaner motor 1. Under the ball bearing part 4 which is installed on the upper side and performs rolling motion on the rotation of the motor shaft 3, a motor shaft insertion hole 5 is laid in the center, and a stepped portion is formed around the motor shaft insertion hole 5. 6) is installed in the concave dust penetration prevention washer (7) is installed to block the brush dust generated from the motor (1).
이와같은 구조로 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention composed of such a structure as follows.
제3도 및 제4도에 도시한 바와같이, 모터(1)가 설치된 모터하우징(2)의 상측 볼 베어링부(4)의 하단으로 모터축(3)이 통과되는 오목형 분진 참투방지와셔(7)를 설치함으로써, 모터(1)에서 발생되는 브러쉬분진이 공기의 유입에 따른 역류현상으로 하우징(2)상측으로 상승시 상기 분진침투방지와셔(7)에 의해 유효하게 차단되어 그 상측의 볼 베어링부(4)의 내륜으로 브러쉬 분진이 침투되는 것을 막을수 있으며, 이로인한 베어링의 수명을 가일층 연장시킬 수가 있는 것이다.As shown in FIGS. 3 and 4, a concave dust preventing washer through which the motor shaft 3 passes through the lower end of the upper ball bearing part 4 of the motor housing 2 in which the motor 1 is installed ( 7), the brush dust generated from the motor 1 is effectively blocked by the dust penetration preventing washer 7 when the brush dust ascends upwards to the housing 2 due to a backflow phenomenon due to the inflow of air, and the ball on the upper side It is possible to prevent the brush dust from penetrating into the inner ring of the bearing portion 4, thereby further extending the life of the bearing.
상술한 바와같이 본 고안에 의한 청소기용 모터의 볼 베어링부 브러쉬분진방지장치에 의하면, 청소기용 모터의 하우징상측에 설치되어 모터축의 회전에 구름운동을 하는 볼 베어링부 하측으로 중앙에 모터축 삽입홀이 천설되고, 모터축 삽입홀 주연에 단턱이 입설된 오목형 분진침투방지와셔를 설치함으로써, 정류자 모터에서 발생되는 브러쉬분진의 볼 베어링부 침투를 유효하게 차단시키며, 이로인한 모터의 수명을 연장시킬수 있는 잇점이 있다.As described above, according to the brush dust prevention device of the ball bearing part of the cleaner motor according to the present invention, the motor shaft insertion hole is provided at the center of the lower part of the ball bearing part installed on the housing of the cleaner motor and performing rolling motion to rotate the motor shaft. By installing the concave dust penetration preventing washer installed in the periphery of the motor shaft insertion hole, the penetration of the ball bearing part of the brush dust generated in the commutator motor can be effectively prevented, thereby extending the life of the motor. There is an advantage.
