And a power changer for selectively transmitting power of the motor to the inserted bearing and to the deshrink or wash shaft.

또한, 베어링이 세탁축과 탈수축 사이에 삽입된 상태로 유지되기 위해, 탈수축의 내주면에는 베어링이 압입 설치되는 압입부가 형성된다.In addition, in order to keep the bearing inserted between the washing shaft and the dehydration shaft, an indentation in which the bearing is press-installed is formed on the inner circumferential surface of the dehydration shaft.

한편, 종래의 세탁기용 클러치는 베어링을 압입부에 압입할 때 베어링이 비틀리는 문제점을 가지고 있었다. 이렇게, 베어링이 비틀릴 경우, 베어링의 볼과 외륜과 내륜 사이에 힘의 불균형이 발생하게 되고, 외륜, 내륜, 볼 중 어느 한쪽이 과도하게 눌리게 된다. 이렇게 비틀려진 베어링으로 인해, 세탁축이 탈수축내에서 회전시 소음 및 진동이 발생하고, 이로 인해 클러치의 내구성이 저하된다.On the other hand, the conventional clutch for a washing machine had a problem that the bearing is twisted when the bearing is pressed into the press-fitting part. In this way, when the bearing is twisted, a force imbalance occurs between the ball of the bearing and the outer ring and the inner ring, and one of the outer ring, the inner ring, and the ball is excessively pressed. Due to this twisted bearing, noise and vibration are generated when the wash shaft rotates in the dehydration shaft, thereby degrading the durability of the clutch.

Move in the direction of the arrow. At this time, the sliding coupler 650 is coupled to the rotor bushing 535, the rotational force of the rotor 500 is transmitted to both the dehydration shaft 100 and the washing shaft 200.

반면, 세탁모드로 전환하기 위해, 클러치모터어셈블리(600)가 연결링크(630)를 점선화살표 방향으로 당기면, 절환레버(640)는 점선화살표 방향으로 회전하면서, 슬라이딩커플러(650)을 점선화살표 방향으로 이동시킨다. 이때, 슬라이딩커플러(650)는 로터부싱(535)과 분리되어, 로터(500)의 회전력이 세탁축(200)에만 전달된다. 한편, 슬라이딩 커플러(650)의 상면부에는 슬라이딩 커플러(650)로부터 드럼(160)을 지지하는 커플러 스프링(651)이 설치된다.On the other hand, in order to switch to the washing mode, when the clutch motor assembly 600 pulls the connection link 630 in the dotted arrow direction, the switching lever 640 rotates in the dotted arrow direction, the sliding coupler 650 in the dotted arrow direction Move to. At this time, the sliding coupler 650 is separated from the rotor bushing 535, the rotational force of the rotor 500 is transmitted only to the washing shaft 200. Meanwhile, a coupler spring 651 supporting the drum 160 from the sliding coupler 650 is installed at the upper surface of the sliding coupler 650.

도 2 및 도 3을 참조하면, 상기 베어링(150)은 하부탈수축(140)의 압입부(141)에 상하부지그(191,192)를 사용하여 압입된다.2 and 3, the bearing 150 is press-fitted into the press-in portion 141 of the lower dehydration shaft 140 using upper and lower jig 191 and 192.

상기 상부지그(191)는 중심돌기(191a)에 베어링(150)이 임시로 장착되도록 베어링(150)의 내륜(151)을 밀어주는 볼(191b)과, 밀어주는 힘을 제공하는 스프링(191c)과, 베어링(150)의 상측에서 눌러줄 때 베어링(150)에 손상되지 않게 하는 보호패드(191d)를 구비한다.The upper jig 191 is a ball (191b) for pushing the inner ring 151 of the bearing 150 so that the bearing 150 is temporarily mounted on the center projection (191a), and a spring (191c) for providing a pushing force And a protection pad 191d to prevent damage to the bearing 150 when pressed from the upper side of the bearing 150.

상기 하부지그(192)는 중심부에 하부탈수축(140)이 끼워지는 중심돌기(192a)를 구비한다.The lower jig 192 has a central protrusion 192a into which the lower dehydration shaft 140 is fitted.

상술한 구성을 가진 상부지그(191)와 하부지그(192)를 사용하여, 하부탈수축(140)을 하부지그(192)의 중심돌기(192a)에 끼워 넣은 다음, 상부지그(191)의 중심돌기(191a)에 베어링(150)을 끼우고, 하부탈수축(140)의 압입부(141)에 베어링(150)을 화살표 방향으로 눌러서 압입시킨다.Using the upper jig 191 and the lower jig 192 having the above-described configuration, the lower dehydration shaft 140 is inserted into the center projection 192a of the lower jig 192 and then the center of the upper jig 191. The bearing 150 is inserted into the protrusion 191a, and the bearing 150 is pressed into the pressing portion 141 of the lower dehydration shaft 140 in the arrow direction to press-fit the bearing 150.

상기 가이드부(142)는 압입부(141)의 상측에 하향 경사지게 형성된 경사면(142)으로 형성된다. 이러한 경사면(142)으로 인해, 베어링(150)을 눌러서 압입부(141)에 압입시킬 때, 베어링(150)이 경사면(142)을 타고 미끄러지면서 비틀림 없이 압입부(141)에 가이드 되어 안착된다.The guide part 142 is formed as an inclined surface 142 formed to be inclined downward on the upper side of the press-in part 141. Due to the inclined surface 142, when the bearing 150 is pressed to press the indentation unit 141, the bearing 150 slides on the inclined surface 142 and is guided and seated on the indentation unit 141 without twisting.

이렇게 압입부(141)에 베어링(150)에 비틀림 없이 안착될 경우, 베어링(150)의 볼(152)과 외륜(153)과 내륜(151) 사이에 힘이 적절하게 분배되어, 외륜(153), 내륜(151), 볼(152) 중 어느 한쪽이 과도하게 눌리게 것이 방지된다. 이로 인해, 세탁축(200)이 탈수축(100)내에서 원활하게 회전하여 소음 및 진동이 방지되고, 또한 클러치의 내구성 역시 향상된다.When the bearing 150 is seated in the press-fitting part 141 without distortion, the force is properly distributed between the ball 152 of the bearing 150, the outer ring 153, and the inner ring 151, and thus the outer ring 153. , Either of the inner ring 151 and the ball 152 is prevented from being excessively pressed. Thus, the washing shaft 200 is smoothly rotated in the dewatering shaft 100 to prevent noise and vibration, and also improve the durability of the clutch.

도 4는 도 1의 탈수축과, 베어링과, 탈수축의 압입부에 베어링을 삽입시킬 때 사용되는 상,하부지그 및 베어링을 압입부에 비틀림없이 압입되도록 안내하는 안내지그를 나타낸 도면이고, 도 5는 도 4의 B부분을 확대한 도면이다.FIG. 4 is a view showing the dehydration shaft of FIG. 1, the bearing, and the upper and lower jig used for inserting the bearing into the pressing portion of the dehydrating shaft, and a guide jig for guiding the bearing to the pressing portion without twisting. FIG. 5. 4 is an enlarged view of a portion B of FIG. 4.

도 4 및 도 5를 참조하면, 가이드부의 다른 실시예로, 가이드부는 베어링(150)을 눌러서 압입부(141)에 압입시킬 때, 베어링(150)이 비틀림없이 가이드되어 안착되게 하는 환형의 압입지그(170)로 구성된다. 압입부(141)의 상측에는 압입지그(170)가 삽입되는 장착홈(141a)이 소정의 깊이로 형성된다.4 and 5, in another embodiment of the guide part, when the guide part is pressed into the press-fitting part 141 by pressing the bearing 150, an annular press-fit jig for allowing the bearing 150 to be guided and seated without distortion. It consists of 170. The mounting groove 141a into which the press-fit jig 170 is inserted is formed at a predetermined depth above the press-fit part 141.

상기 압입지그(170)는, 베어링(150)이 압입구(141)에 압입 설치된 후에는 제거되도록 장착홈(141a)에 분리가능하게 설치된다. 그러나, 압입 설치후에는 지속적으로 베어링(150)을 가이드하기 위해, 압입지그(170)를 장착홈(141a)에 고정 설치할 수도 있을 것이다. 한편, 비틀림방지효과를 더욱 높이기 위하여 압입지그(170) 의 내주면에 하향 경사지게 경사면(171)이 형성된다.The press-fit jig 170 is detachably installed in the mounting groove 141a to be removed after the bearing 150 is press-installed in the press-in hole 141. However, in order to continuously guide the bearing 150 after the press fit installation, the press jig 170 may be fixedly installed in the mounting groove 141a. On the other hand, in order to further increase the effect of the torsion, the inclined surface 171 is formed to be inclined downward on the inner peripheral surface of the press-fit jig 170.

상기 압입지그(170)로 인해, 베어링(150)을 눌러서 압입부(141)에 압입시킬 때, 베어링(150)이 경사면(171)을 타고 미끄러지면서 비틀림 없이 압입부(141)에 가이드 되어 안착된다.Due to the press jig 170, when the bearing 150 is pressed to press the press unit 141, the bearing 150 slides on the inclined surface 171 and is guided and seated in the press unit 141 without twisting. .

이렇게 압입부(141)에 베어링(150)이 비틀림 없이 안착될 경우, 베어링(150)의 볼(152)과 외륜(153)과 내륜(151) 사이에 힘이 적절하게 분배되어, 외륜(153), 내륜(151), 볼(152) 중 어느 한쪽이 과도하게 눌리게 것이 방지된다. 이로 인해, 세탁축(200)이 탈수축(100)내에서 원활하게 회전하여 소음 및 진동이 방지되고, 또한 클러치의 내구성 역시 향상된다.When the bearing 150 is seated on the press-fitting portion 141 without twisting, the force is appropriately distributed between the ball 152 of the bearing 150, the outer ring 153, and the inner ring 151, and thus the outer ring 153. , Either of the inner ring 151 and the ball 152 is prevented from being excessively pressed. Thus, the washing shaft 200 is smoothly rotated in the dewatering shaft 100 to prevent noise and vibration, and also improve the durability of the clutch.
