드럼세탁기의 구동부{Drive structure for drum type washing machine}Drive structure for drum washing machine {Drive structure for drum type washing machine}

본 발명은 드럼세탁기 내의 드럼을 회동시키기 위해 터브의 후방에 장착되는 드럼세탁기의 구동부에 관한 것이다.The present invention relates to a drive of a drum washing machine mounted to the rear of a tub for rotating the drum in the drum washing machine.

일반적으로, 드럼 세탁 방식은 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서, 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼빠는 세탁효과를 낼 수 있다.In general, the drum washing method is a method in which the laundry is performed using the friction force of the rotating drum and the laundry by receiving the driving force of the motor while the detergent, the washing water, and the laundry are put in the drum. These don't get tangled with each other, and can be washed and pounded.

도 1 상기와 같은 종래의 드럼세탁기의 내부 구조를 나타낸 것으로, 도 1에 도시된 바와 같이, 캐비닛(미도시) 내측에 원통형의 터브(1; tub)가 설치되고, 상기 터브(1) 내측에는 원통형의 드럼(2)이 회전가능하게 설치된다.1 is a view illustrating an internal structure of a conventional drum washing machine as illustrated in FIG. 1, a tub is formed in a tub inside a cabinet (not shown), and inside the tub 1. The cylindrical drum 2 is rotatably installed.

그리고, 상기 터브(1) 하부 일측에는 상기 드럼(2)을 회동시키기 위한 구동수단으로서 모터(5)가 설치되고, 상기 모터(5)에는 모터 풀리(51)가 축연결된다.A lower side of the tub 1 is provided with a motor 5 as a driving means for rotating the drum 2, and a motor pulley 51 is axially connected to the motor 5.

한편, 상기 드럼(2) 후방에 형성된 스파이더(21)에는 구동축(3)의 일단이 연결되고, 상기 구동축(3) 타단에는 드럼 풀리(31)가 설치되는데, 이 드럼 풀리(31)는 동력전달요소인 벨트(6)를 매개로 모터(5)에 연결된 모터 풀리(51)와 연결되어 회동하게 된다.Meanwhile, one end of the drive shaft 3 is connected to the spider 21 formed at the rear of the drum 2, and a drum pulley 31 is installed at the other end of the drive shaft 3, and the drum pulley 31 transmits power. It is connected to the motor pulley 51 connected to the motor 5 via the belt 6 which is an element to rotate.

그리고, 상기 터브(1)의 후방부 중심부에는 상기 드럼(2)의 후방에 설치된 구동축(3)이 관통하면서 결합하는 전,후방베어링(41, 42)이 압입되어 설치되는 베어링하우징(11)이 인서트성형되어 일체로 형성되어 있다.In addition, a bearing housing 11 in which front and rear bearings 41 and 42 are press-fitted is installed at a central portion of the rear portion of the tub 1 while the driving shaft 3 installed at the rear of the drum 2 penetrates. It is insert molded and integrally formed.

따라서, 상기와 같은 구성으로 이루어진 드럼세탁기는 다음과 같이 작동한다.Therefore, the drum washing machine having the above configuration operates as follows.

드럼(2) 내에 세탁물과 세탁수가 채워진 다음, 모터(5)에 전원이 인가되면 모터(5)의 작동에 의해 모터 풀리(51)가 회전하게 되고, 상기 모터 풀리(51)의 회전력이 상기 벨트(6)에 의해 드럼 풀리(31)에 전달되어 드럼 풀리(31)가 회전하게 되며, 이에 따라 드럼 풀리(31)에 연결된 구동축(3)이 회전하면서 드럼(2)을 회동시켜 세탁을 수행하게 된다.After the laundry and the washing water are filled in the drum 2, when power is applied to the motor 5, the motor pulley 51 is rotated by the operation of the motor 5, and the rotational force of the motor pulley 51 is applied to the belt. (6) is transmitted to the drum pulley 31 to rotate the drum pulley 31, thereby rotating the drive shaft (3) connected to the drum pulley 31 to rotate the drum (2) to perform the washing do.

이 때, 상기 드럼(2)이 회동하면서 세탁을 수행하는 과정에서, 상기 드럼(2)에 연결된 구동축(3)을 지지하는 전,후방베어링(41, 42)들은 드럼(2)의 자중과, 드럼(2) 내의 세탁물과 세탁수 및, 세탁물의 회전에 의한 원심력을 지탱하게 되며, 상기 전,후방베어링(41, 42) 각각에서 지지하는 힘은 내측베어링(41)과 외측베어링(42) 간의 간격이 커질수록 작아진다.At this time, in the process of washing the drum (2) while rotating, the front and rear bearings (41, 42) supporting the drive shaft (3) connected to the drum (2) and the weight of the drum (2), The laundry in the drum 2 and the wash water, and the centrifugal force by the rotation of the laundry is supported, the force supported by each of the front and rear bearings (41, 42) between the inner bearing 41 and the outer bearing 42 The larger the interval, the smaller.

따라서, 상기 내측베어링(41)과 외측베어링(42) 간의 설치 간격을 크게 함으로써 각각의 베어링에서 지탱하는 하중을 분산시키고, 이로써 베어링들의 수명을 연장시킬 수 있음은 쉽게 이해될 것이다.Therefore, it will be readily understood that by increasing the installation interval between the inner bearing 41 and the outer bearing 42, the load bearing in each bearing can be distributed, thereby extending the life of the bearings.

그러나, 상기와 같은 종래의 드럼세탁기의 구동부 구조에 있어서, 상기 전,후방베어링(41, 42)들 사이의 간격을 크게 하고자 할 경우, 이들 전,후방베어링(41, 42)이 장착되는 베어링하우징(11)이 길어져야 하고, 그로 인해 드럼(2)의 길이가 줄어들어 용적이 줄어들게 되거나, 혹은 드럼 풀리(31)가 뒤쪽으로 더 이동하게 되어 드럼세탁기의 캐비닛 내에 설치하기가 어렵게 되는 문제점이 있었다.However, in the structure of the drive unit of the conventional drum washing machine as described above, in order to increase the distance between the front and rear bearings 41 and 42, the bearing housings to which the front and rear bearings 41 and 42 are mounted are installed. (11) should be long, thereby reducing the length of the drum (2) to reduce the volume, or there is a problem that the drum pulley 31 is further moved to the rear to be difficult to install in the cabinet of the drum washing machine.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 드럼세탁기의 구동부의 전체적인 길이는 거의 그대로 유지하면서도 구동축을 지지하는베어링 간의 간격을 크게 할 수 있도록 된 드럼세탁기의 구동부를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, to provide a driving unit of the drum washing machine to increase the distance between the bearings for supporting the drive shaft while maintaining the overall length of the drive unit of the drum washing machine. There is this.

The rotor 520 is coupled to the drive shaft 30 by being tightened by the nut 522 inserted from the rear of the drive shaft 30.

또한, 상기 모터하우징(510)의 후방면 중심부에는 상기 구동축(30)의 후단부를 회동가능하게 지지하기 위한 전,후방베어링(41, 42)이 삽입 장착되는 후방 베어링하우징(511)이 일체로 형성되어 있다.In addition, the rear bearing housing 511 is integrally formed at the center of the rear surface of the motor housing 510 in which front and rear bearings 41 and 42 are inserted and mounted to support the rear end of the drive shaft 30 to be rotatable. It is.

그리고, 상기 모터하우징(510)은 상기 터브(10)의 후방면과 결합하게 되는 전방 모서리부위에 플랜지(512)가 형성되어 있는데, 이 플랜지(512)가 터브(10) 후방에 형성된 베어링하우징(110)과 연접한 상태에서 볼트(80)로 체결됨으로써 모터하우징(510)이 터브(10) 후방면에 고정되게 된다.In addition, the motor housing 510 has a flange 512 is formed on the front edge portion to be coupled to the rear surface of the tub 10, the flange 512 bearing housing formed in the tub 10 rear ( The motor housing 510 is fixed to the rear surface of the tub 10 by being fastened with the bolt 80 in a state of being in contact with the 110.

한편, 상기 구동축(30)이 드럼(20) 후방의 스파이더(210)와 결합된 부분에서부터 전방 베어링하우징(110)까지의 영역에는 구동축(30)의 녹방지를 위해 황동 재질의 부싱(60)이 압입되어 설치되고, 상기 부싱(60)의 외측면에는 베어링 측으로의 수분 침투를 방지하기 위한 실링부재(70)가 설치된다.On the other hand, in the region from the drive shaft 30 coupled to the spider 210 behind the drum 20 to the front bearing housing 110, a bushing 60 made of brass to prevent rust of the drive shaft 30 is provided. Press-fitted, the outer surface of the bushing 60 is provided with a sealing member 70 for preventing the penetration of moisture to the bearing side.

전술한 바와 같이 본 발명의 구동부의 구조를 살펴보면, 드럼(20)에 연결된 구동축(30)을 회동시키기 위한 구동수단으로서 직결식 모터(500)가 사용되고, 이 직결식 모터(500)를 중심으로 하여 모터(500)의 전방 및 후방 각각에 상기 구동축(30)의 전방 및 후방부를 지지하게 되는 전,후방베어링(41, 42)이 장착되게 되므로, 구동부 전체의 길이는 동일하게 유지하면서도 전,후방베어링(41, 42) 간의 간격이 기존보다 더 커지게 되고, 이에 따라 각 베어링에 가해지는 힘이 적어지게 된다.Looking at the structure of the drive unit of the present invention as described above, the direct type motor 500 is used as a driving means for rotating the drive shaft 30 connected to the drum 20, and the direct type motor 500 Since the front and rear bearings 41 and 42 supporting the front and rear portions of the drive shaft 30 are respectively mounted on the front and the rear of the motor 500, the front and rear bearings are maintained while maintaining the same length of the entire driving unit. The distance between the 41 and 42 becomes larger than the conventional one, and thus the force applied to each bearing becomes less.
