본 고안은 경운기 바퀴를 장착하는 허부와 회전축간의 취부장치에 관한 것이다. 종래의 경운기용 허부의 취부장치는 디스크상의 허부중심 보스의 일부를 덮개형으로 분할하고 이를 볼트 조임하며, 허부와 보수 사이에 키를 개재하고, 내면에 스페이스환을 끼워 축단에 볼트 조임하여 사용되는 것과, 제1도와 같이 회전축(10)과 허부(20) 사이에 조임환(30)을 개재시켜, 회전축(10)의 키홈(10')과 조임환(30)의 절결부(30') 및 허부(20)의 키홈(20')에 끼워지도록 별도의 키(30a)를 삽입하여 회전축(10)의 회전력을 허부(20)에 전달되도록 된 본건 출원인의 실용신안등록 제43234호 및 실용신안등록출원 제92-23159호가 고안되어 사용되어 왔으나, 상기의 이러한 별도의 키를 이용하여 회전축에 허부를 고정시키는 방법은 회전축의 외주와 허부의 내주 사이에 결합시 틈이 발생되므로 경운기 운행중 진동이 회전축에 전달되어 키가 회전축의 키홈과 허부의 키홈 사이에서 흔들림이 생겨 이 마찰로 인하여 키홈이 확장이 되므로 회전축상에 고정된 허부가 좌우 유동이 생기므로 경운기 운행중 허부에 결합된 바퀴가 견고하게 결합되지 못하는 결점이 있었다.The present invention relates to a mounting device between the hub and the rotating shaft for mounting the cultivator wheel. Conventional cultivator hub mounting device is used by dividing part of hub center boss on disk into cover type and bolting it, interposing key between hub and repair, and inserting a space ring on the inner surface and bolting to shaft end. 1, the notch 30 'and the lower part of the key groove 10' and the tightening ring 30 of the rotating shaft 10 are interposed between the rotating shaft 10 and the lower part 20 as shown in FIG. Utility model registration No. 43234 and Utility Model Registration Application No. of the applicant of the present application to insert a separate key (30a) to be inserted into the key groove 20 'of 20) to transmit the rotational force of the rotary shaft 10 to the hub 20 No. 92-23159 has been devised and used, but the method of fixing the hub to the rotary shaft by using such a separate key is a vibration occurs during the operation of the cultivator because a gap is generated between the outer circumference of the rotary shaft and the inner circumference of the hub. The key is the keyway Since the key-way between the shaking blossomed due to friction because the extension is splined the imaginary part fixed to the axis of rotation the advent of the left and right flow was not a disadvantage that the wheel coupled to the tiller while driving imaginary part is not rigidly coupled.
본 고안은 이러한 문제점을 해소하기 위해 안출한 것으로서, 회전축과 허부 사이에 개재되는 조임환에 일체로 키와 절결부가 구비되도록 형성하여 별도의 키가 필요없이 조임환의 개재만으로도 회전축에 허부를 연결 고정시킬 수 있도록 고안된 것이다.The present invention has been made to solve this problem, it is formed to be provided with a key and a cutout integrally to the tightening ring interposed between the rotary shaft and the hub to fix the hook connected to the rotary shaft only by the interposition of the tightening ring without the need for a separate key. It is designed to be.
이하, 첨부도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다. 경운기 구동기어 박스에 장착된 회전축(1)상에 허부(2) 및 스페이스환(4), 보강링(5)이 고정너트(6)로 결합되는 허부의 취부장치에 있어서, 회전축(1)과 허부(2) 사이에 키(3a)(3b)와 절결부(3')가 일체로 구비된 ＂＂형의 조임환(3)을 회전축(1)의 키홈(1')과 허부(2)의 키홈(2')에 조임환(3)의 키(3a)(3b)가 삽입되도록 개재시킨 구성이다. 미설명부호4'는 회전축에 끼워지는 스페이스환이다. 이와 같이 구성된 본 고안은 경운기 바퀴회전축(1)에 하부(2)를 조립하자면 먼저 통상의 스페이스환(4')을 끼우고, 제4도와 같이 ＂＂형의 조임환(3)에 내향된 키(3a) 부분이 회전축(1)의 키홈(1')에 인입되도록 조임환(3)을 회전축(1)상에 삽입하고, 허부(2)의 키홈(2')에 조임환(3)의 외향된 키(3b)가 삽입 대응되도록 허부(2)를 끼우고 일측에 스페이스환을(4) 및 보강링(5)과 함께 고정너트(6)으로 고정시키게 된다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the mounting part of the hub, in which the hub part 2, the space ring 4, and the reinforcing ring 5 are coupled to the fixed nut 6 on the rotary shaft 1 mounted on the cultivator drive gear box, the rotary shaft 1 and 된 with a key 3a, 3b and a cutout 3 'integrally provided between the hub 2 The jaw-shaped clamping ring 3 is interposed so that the key 3a and 3b of the clamping ring 3 may be inserted into the key groove 1 'of the rotary shaft 1 and the key groove 2' of the hub 2. Reference numeral 4 'is a space ring fitted to the rotating shaft. The present invention configured as described above is to assemble the lower portion (2) to the cultivator wheel rotation shaft (1), first insert the ordinary space ring (4 '), as shown in Figure 4 Insert the tightening ring 3 on the rotating shaft 1 so that the portion of the key 3a inwardly into the X-shaped tightening ring 3 enters the key groove 1 'of the rotating shaft 1, and the key groove of the hub 2 ( 2 ') to insert the outward key (3b) of the tightening ring (3) to the corresponding correspondence and to fix the space ring (4) and the reinforcing ring (5) together with the fixing nut (6) on one side do.
이와 같이 결합된 본 고안은 경운기 운행중 회전축(1)에 심한 진동이 발생되더라도 회전축(1)과 허부(2) 사이에 개재된 조임환(3)과 일체로 내외향 돌출된 키(3a)(3b)가 회전축(1) 키홈(1')과 허부(2) 키홈(2')에 끼워진 상태에서 조임환(3)이 절결부(3')에 의하여 외향으로 벌어지려는 탄발력이 생기므로 허부(2)와 조임환(2)이 견고히 밀착 고정된다.The present invention coupled as described above has a key (3a) (3b) protruding inward and outward integrally with the tightening ring (3) interposed between the rotary shaft (1) and the hub (2) even if severe vibration is generated on the rotary shaft (1) during the operation of the cultivator. Rotational shaft (1) Since the tightening ring (3) in the state is fitted in the key groove (1 ') and the key portion (2) key groove (2') to open outward by the cutout (3 ') And tightening ring (2) is tightly fixed.
따라서, 회전축(1)의 진동에도 키(3a)(3b)가 회전축(1)의 키홈(1')과 허부(2)의 키홈(2')내에서 흔들리지 않으므로 마찰에 의한 키홈 확장을 방지하여 경운기 바퀴회전축과 허부간의 취부장치를 견고히 할 수 있게 된것이다.Therefore, the keys 3a and 3b do not shake in the key groove 1 'of the rotary shaft 1 and the key groove 2' of the hub 2 even in the vibration of the rotary shaft 1, thereby preventing the expansion of the key groove by friction. It is possible to secure the mounting device between the wheel of the tiller and the hub.
