본 고안은 세탁기의 동력전달을 이루는 트랜스미션구조에 관한 것으로서, 더욱더 상세하게는 세탁축 길이를 축소하여 제작비용을 줄이고, 간단한 구조로 클러치기능을 수행 할 수 있도록 함은 물론, 세탁축의 힘을 최소화하여 경제적이고 안전한 동력전달이 이루어지도록 하는 세탁기용 트랜스미션의 구조에 관한 것이다.The present invention relates to a transmission structure that achieves power transmission of a washing machine, and more particularly, to reduce the manufacturing cost by reducing the length of the washing shaft, and to minimize the force of the washing shaft as well as to perform the clutch function with a simple structure. It relates to a structure of a transmission for a washing machine to ensure economical and safe power transmission.
일반적으로 트랜스미션은 모우터의 동력으로 회전하여 세탁 또는 탈수주기에 따라 적절한 동력을 공급하여서 세탁효율을 높이고 있으며 중량체로 구비되고 있다.In general, the transmission is rotated by the power of the motor to increase the washing efficiency by supplying the appropriate power in accordance with the washing or dehydration cycle and is provided as a weight.
여기에서 종래 트랜스미션은 제 3도에 도시된 바와같이 입력축(1) 및 탈수축(2) 지지용베어링(3)이 각각 한 개씩 구비되고, 장축으로 이루어지는 세탁축의 중앙에는 세탁부하가 인가되도록 설치되며, 상,하부가 하나의 축을 중심으로 조립되어 있다.Here, the conventional transmission is provided with one input shaft (1) and dehydration shaft (2) support bearings (3), respectively, as shown in Figure 3, and is installed so that the washing load is applied to the center of the washing shaft consisting of a long axis The upper and lower parts are assembled around one axis.
그리고 입력축(1)은 깊은 홀(5)이 있기 때문에 상대적으로 세탁축이 길어지도록 형성되고 있다.Since the input shaft 1 has a deep hole 5, the input shaft 1 is formed to be relatively long.
따라서, 입력축(1)과 탈수축(2)이 각각 하나의 베어링만으로 지지되어 있기 때문에 일측으로 기울어질 우려가 있고, 양단이 지지된 긴 세탁축의 중앙에서 세탁부하가 인가되어 축이 휠 수 있으며, 하나의 축을 중심으로 모든 기구물의 동심을 맞아야 함으로서 치수관리가 필요하게 됨은 물론, 상기 입력축(1)에 깊은 홀(5)을 형성하여야 함으로서, 작업자가 부품을 제작시 애로를 느끼게 됨으로서, 가공비용이 상승됨과 동시에 세탁축의 길이가 길어 특수제작 기계를 구비하여야 함으로서, 제작비가 상승되는 결점이 있었다.Therefore, since the input shaft 1 and the dehydration shaft 2 are each supported by only one bearing, there is a fear that the input shaft 1 and the dehydration shaft 2 are inclined to one side, and the washing load is applied at the center of the long washing shaft, which is supported at both ends. As the concentricity of all the mechanisms must be centered on one axis, dimensional management is required, as well as the deep hole 5 must be formed in the input shaft 1, so that the worker feels difficulties when manufacturing the parts, thereby reducing the machining cost. At the same time, as the length of the washing shaft is long, a special manufacturing machine must be provided, which increases the manufacturing cost.
이에, 본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 그 목적은 저렴한 비용으로 안전하고 정밀한 구조로 제작하여 사용이 편리토록 하는 트랜스미션을 제공하는 데 있다.Therefore, the present invention has been devised to solve such a conventional drawback, and its purpose is to provide a transmission that is easy to use by producing a safe and precise structure at a low cost.
상기 목적을 달성하기 위한 기술적인 수단으로는 하우징에 상,하로 내장된 메탈베어링에 입력축을 끼우고 그 하단에 풀리를 결합부재로 체결한 것과 입력축 상단에 끼워지는 세탁축 하단에는 일방향 니들베어링을 설치하고 탈수축의 상,하단에는 볼베어링을 끼워 저수조 받침판과 하우징커버에 지지하여 구성된 것이 제공 된다.The technical means for achieving the above object is to insert the input shaft into the metal bearings built up and down in the housing, and to fasten the pulley with a coupling member at the bottom thereof and to install the one-way needle bearing at the bottom of the washing shaft fitted to the top of the input shaft. In addition, the upper and lower ends of the deshrinking shaft are provided with a ball bearing fitted to the reservoir support plate and the housing cover.

한편, 상기 일방향 니들베어링(32)의 안쪽에는 세탁축(18)의 밑단이 끼워져있고 세탁축(18)의 외부에는 탈수축(36이 있으며 이 탈수축(36)은 저수조 받침판(16)에 안착된 볼베어링(38)과 하우징커버(40)에 장착된 볼베어링(38a)에 의해 양쪽으로 지지되고 있다.On the other hand, the inner end of the one-way needle bearing 32 is fitted with the bottom of the washing shaft 18, the outer side of the washing shaft 18 has a dehydration shaft 36 and the dehydration shaft 36 is seated on the reservoir support plate 16 Both sides are supported by the ball bearing 38 and the ball bearing 38a attached to the housing cover 40.
또한, 상기 편심캠(26)은 하우징(42)을 관통한 동기모우터(24)의 회전축(44)에 끼워져 있고 입력축(12)과 세탁축(18)은 상부와 하부에 각각 설치된 오일레스 메탈베어링(46)(46a)(48)(48a)에 지지된다.In addition, the eccentric cam 26 is fitted to the rotating shaft 44 of the synchronous motor 24 penetrating the housing 42, the input shaft 12 and the washing shaft 18 is an oilless metal installed on the top and bottom, respectively. The bearings 46, 46a, 48 and 48a are supported.
한편, 상기 벨트(50)와 결속되는 풀리(10)는 입력축(12) 과 체결부재(52)로 결합되고, 상기 입력축(12)의 하단은 하우징(42)에 내장된 메탈베어링(46)(46a)(48)(48a) 에 끼워져 지지되는 지지축(54)이 형성되며, 상기 메탈베어링(48)(48a) 하부에는 오일실(56)이 끼워지고 지지축(54) 하단에는 나사봉(58)이 형성되어 와셔(60)와 고정 와셔(60a)를 끼운후 부시(62)와 일체로 풀리(10)에 삽입하여 또 다른 와셔(60b)를 끼워서 체결부재(52)와 너트로 체결한다.On the other hand, the pulley 10 is coupled to the belt 50 is coupled to the input shaft 12 and the fastening member 52, the lower end of the input shaft 12 is a metal bearing 46 (built in the housing 42) ( 46a, 48, and 48a are formed to support the support shaft 54, the lower portion of the metal bearing (48) (48a) oil chamber 56 is fitted and the lower end of the support shaft 54 screw rod ( 58 is formed to insert the washer 60 and the fixed washer (60a) and then inserted into the pulley (10) integrally with the bush 62 to insert another washer (60b) to fasten with the fastening member 52 and the nut. .
또한, 입력축(12)과 연결되는 부재들은 하우징(42)에 내장되어 하우징커버(40)로 보호된다.In addition, members connected to the input shaft 12 are embedded in the housing 42 and protected by the housing cover 40.
도면중 미설명 부호 ; 64는 스플라인, 66,66a는 랫치, 68은 브레이크드럼 , 70은 역회전방지스프링을 나타낸다.Unexplained code in the drawing; 64 is a spline, 66, 66a is a latch, 68 is a brake drum, and 70 is a reverse rotation spring.
이와같은 구성으로 이루어지는 본 고안은 세탁시 풀리(10)에서의 동력이 입력축(12)에 전달되면 입력축(12)의 중앙에 있는 기어(30)를 통해 감속반전부를 거쳐 피니언에지테이터(22)에 이어지고 이어서 피니언에지테이터(22)의 내면에 있는 스플라인(64)을 통해 세탁축(18)에 전달되어 세탁을 수행하게 된다.The present invention having such a configuration is that when the power from the pulley 10 is transmitted to the input shaft 12 during washing, the pinion digitator 22 passes through the reduction gear reverse portion through the gear 30 at the center of the input shaft 12. Subsequently, it is transmitted to the washing shaft 18 through the spline 64 on the inner surface of the pinion edgeator 22 to perform the washing.
이때 일방향 니들베어링(32)은 풀리는 방향이 되어 입력축(12)에서의 동력이 세탁축(18)에 직접 전달되지 아니하며 세탁축(18)이 반전시 일방향 니들베어링(32)을 구속하는 방향이 되더라도 일방향 니들베어링(32)이 안착된 입력축(12)의 속도가 세탁축(18) 속도보다 빨라져도 구속됨이 없이 원활한 세탁기능을 수행할 수 있다.At this time, the one-way needle bearing 32 is in the unwinding direction so that the power from the input shaft 12 is not directly transmitted to the washing shaft 18, and the washing shaft 18 becomes the direction of restraining the one-way needle bearing 32 when inverted. Even if the speed of the input shaft 12 on which the one-way needle bearing 32 is seated is faster than the speed of the washing shaft 18, a smooth washing function can be performed without being restrained.
또한, 탈수시는 편심캠(26)의 작동에 의해 리프트(28)가 상승하면서 피니언에지테이터(22)를 상승시켜 그 상단에 마련된 랫치(66)와 탈수축(36) 하단에 잇는 랫치(66a)가 맞물리게 한 뒤 입력풀리(10)가 탈수방향(세탁행정의 반대방향)으로 회전하면 입력축(12)을 거쳐 상부의 일방향 니들베어링(32)을 통해 세탁축(18)으로 탈수능력이 전달되고 이어서 세탁축(18)의 스플라인(64a)에서 피니언에지테이터(22)의 랫치(66)를 통해 탈수축(36)의 랫치(66a)와 연결되어 세탁축(18), 탈수축(5)이 일체로 되어 탈수동작을 행하게 된다.In addition, during dehydration, the lift 28 is raised by the operation of the eccentric cam 26 to raise the pinion edger 22, and the latch 66a provided at the upper end of the latch 66 and the dehydration shaft 36 is provided. When the input pulley 10 rotates in the dehydration direction (the opposite direction of the washing stroke) after the mesh is engaged, the dehydration capacity is transmitted to the washing shaft 18 through the input shaft 12 through the upper one-way needle bearing 32. Subsequently, the spline 64a of the washing shaft 18 is connected to the latch 66a of the dehydration shaft 36 through the latch 66 of the pinion edger 22 so that the washing shaft 18 and the dewatering shaft 5 are connected. Integrally perform dehydration operation.
그리고, 세탁으로의 복원은 편심캠(26)이 회전하면 스프링-클러치의 복원력에 의해 피니언에지테이터(22)와 리프트(28)가 하강하면서 기어부가 맞물려 세탁위치가 된다.In addition, when the eccentric cam 26 rotates, the pinion edge 22 and the lift 28 descend by the restoring force of the spring clutch when the eccentric cam 26 rotates, and the gear part is engaged with the washing position.
또한 브레이크드럼(68)의 상부에는 역회전방지스프링(70)이 탈수축에 끼워져 있어 세탁시 탈수조의 역회전을 막아주고 있다.In addition, the upper portion of the brake drum 68, the reverse rotation prevention spring 70 is fitted to the dehydration shaft to prevent the reverse rotation of the dehydration tank during washing.
이와같이 본원고안은 간단한 구조로 세탁과 탈수행정을 이룰 수 있도록 하고 작동중 안전한 상태를 유지하며 제작비용을 저렴하게 할 수 있는 신규 고안인 것이다.As described above, the present application is a new design that can achieve washing and dehydration administration with a simple structure, maintains a safe state during operation, and lowers manufacturing costs.
