본 고안은 농기구 트랙터의 동력부와 작업기구사이에 연결사용되는 회전축의 조인트부에 토오크(Torque) 조정이 가능한 안전장치를 설치하여 작업기구로 부터 갑작스럽게 발생하는 과부하시 트랙터 기구부에 안전을 꾀하게 하고 또 토오크본체내의 원판 내부 유동핀의 코일스프링탄력을 외부에서 조정나사로 조정사용할 수 있게 하여 농기구 트랙터를 농촌에서 보다 안전하고 편리하게 장기간 이용할 수 있도록 한 농기구 트랙터용 토오크 조정안전장치에 관한 것이다.The present invention installs a safety device that can adjust the torque at the joint of the rotating shaft that is used between the power unit and the work tool of the farm equipment tractor, and makes the tractor mechanism safe in case of sudden overload occurring from the work tool. In addition, the present invention relates to a torque adjustment safety device for a farm equipment tractor, which enables the coil spring elasticity of the inner flow pin of the disc body in the torque body to be adjusted and used externally with an adjustment screw so that the farm equipment tractor can be used more safely and conveniently in rural areas.
종래 디스크식 조인트 안전장치는 동력전달부의 입력축에 2개의 고정원판을 8개의 보울트와 스프링으로 탄력 설치하고 그 고정원판 내면에는 석면 마찰판을 부착한 출력축의 마찰판이 과부하의 저항힘을 받으면 슬라이딩 회전을 하도록 구성되어 있으므로 이는 석면마찰판과 라이닝사이에 마모와 열발생이 크므로 부품의 손상이 많아 사용수명이 짧은 폐단이 있고 또 고정원판은 8개의 보울트와 스프링으로 게이지를 사용하여 균형을 맞추어야 하는 불편이 있을뿐더러 마찰판의 접촉균형이 불균형시 작동이 불안전한 결함이 있었다.Conventional disc joint safety device resiliently installs two fixed disks with eight bolts and springs on the input shaft of the power transmission unit, and the friction plate of the output shaft with asbestos friction plate attached to the inner surface of the fixed disk is subjected to sliding rotation when subjected to overload resistance. Because it is composed, this is because there is a great wear and heat generation between the asbestos friction plate and the lining, so there is a lot of damage to the parts, so there is a short end of the service life. In addition, when the contact balance of the friction plate was unbalanced, the operation was unstable.
본 고안은 종래 그와 같은 결함을 해소하고 또 장기간 안전하게 사용될 수 있으며 토오크조정이 가능케 하여 농기구 트랙터의 마력수(50마력∼100마력)에 관계없이 사용할수 있도록 착안한 것인데 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been conceived to solve such a defect and to be able to safely use it for a long time and to adjust the torque so that it can be used regardless of the number of horsepower (50 horsepower to 100 horsepower) of the farm equipment tractor. The explanation is as follows.
동력전달 입력축(3)의 조인트부(2)에 토오크본체(1)를 연결형성하여 조정나사(4)의 주입구멍(5)을 중간에 형성한 내측으로 볼베어링(6)을 끼워 고정하고 또 토오크본체(1) 내벽면의 중간부에는 오목한 라인으로된 원형궤도(7)를 형성하고 그 대향부에 곡면으로 형성된 형성된 홈(8), (8')을 형성하였다.Torque main body 1 is connected to joint part 2 of power transmission input shaft 3 to fix ball bearing 6 into the inner side of injection hole 5 of adjustment screw 4, and then torque is fixed. In the middle of the inner wall surface of the main body 1, circular tracks 7 formed of concave lines were formed, and grooves 8 and 8 'formed in curved portions were formed on opposite sides thereof.
또한 토오크본체(1)내에 끼워 결합하는 하는 출력축(3') 선단에는 원판(9)과 끼움편(10)을 연결형성하여 토오크본체(1)내의 원형궤도(7)와 볼베어링(6) 내면에 각각 끼워지도록 하고 또 원판(9)의 중심부에 뚫은 안내구멍(11)에는 양측에서 코일스프링(12), (12')과 구면(15)을 가진 유동핀(16), (16')을 끼워지게 하고 또 끼움편(10)에는 나사공(13)을 안내구멍(11)의 중심위치에 있게 형성하여 조정나사(4)를 틀어 박을수 있도록 하고 그 조정나사(4)의 끝에는 원추부(4')로 형성하여 이 원추부(4')가 양 코일 스프링(12), (12')의 내단부를 잡아 주도록 하였다.In addition, the disc 9 and the fitting piece 10 are connected to the front end of the output shaft 3 'to be engaged in the torque main body 1 so that the circular track 7 and the ball bearing 6 inside the torque main body 1 are formed. The guide pins 11 drilled in the center of the disc 9 are fitted with floating pins 16 and 16 'having coil springs 12, 12' and spherical surfaces 15 on both sides thereof. In the fitting piece 10, the screw hole 13 is formed at the center position of the guide hole 11 so that the adjustment screw 4 can be screwed in. At the end of the adjustment screw 4, the conical portion 4 ' ), The conical portion 4 'holds the inner ends of both coil springs 12 and 12'.
또한 원판(9)의 후측은 고정판(14)의 볼베어링(6')에 연결 설치하여 출력축(3')의 회전을 용이하게 하고 고정판(14) 외측에는 토오크 본체(1)와 조립후 고정링(18)을 토오크 본체(1)에 형성된 고정홈(19)에 끼워 고정되게 하였다.In addition, the rear side of the original plate 9 is connected to the ball bearing 6 'of the fixed plate 14 to facilitate the rotation of the output shaft 3', and to the outside of the fixed plate 14 and the torque main body 1 and the fixed ring after assembly ( 18) is fixed to the fixing groove 19 formed in the torque main body (1).
이와 같이 구성되는 본 고안은 토오크 본체(1) 내면의 원형궤도(7) 및 볼베어링(6)의 내면에 코일스프링(12), (12')과 유동핀(16), (16')이 안내구멍(11)에 끼워진 원판(9) 및 끼움편(10)을 끼워 맞춤과 동시에 주입구멍(5)으로 조정나사(4)를 외부에서 끼움편(10)의 나사공(13)에 틀어 박으면 선단 원추부(4')가 코일스프링(12)과 코일스프링(12') 중간을 밀어 수축탄성케 된다. 또한 고정판(14) 외측은 고정링(18)을 토오크 본체(1)의 고정홈(19)에 끼워 고정시키므로서 조립이 되고 또 유동핀(16), (16')은 제2도 제4도의 도시화 같이 홈(8), (8')에 끼워진 상태에 있기 때문에 동력전달 입력축(3)의 토오크 본체(1)와 출력축(3') 의 원판(9)은 일체로 되어져서 동력전달 입력축(3)과 함께 출력축(3')도 회전가능케 된다. 따라서 출력축(3')에 연결설치되는 작업기구도 동력전달을 받아 작업을 할 수 있게 되는데, 본 고안은 작업기구로 부터 갑작스러운 과부하로 인하여 출력축(3')에 저항의 힘을 받게 될때는 그 저항힘이 원형궤도(7)의 양홈(8), (8')에 끼워져 있는 유동핀(16), (16')에 작용하므로 유동핀(16), (16') 은 곡면으로 형성된 홈(8), (8')에서 벗어나, 원형궤도(7)인 오목라인을 타고 회전하므로 입력축(3)의 동력전달과 관계없이 출력축(3')이 헛돌수 있으므로 과부하에도 안전한 효과가 있다.According to the present invention configured as described above, the coil springs 12, 12 ′ and the floating pins 16, 16 ′ are guided to the inner surface of the circular track 7 and the ball bearing 6 on the inner surface of the torque body 1. When the disc 9 and the fitting piece 10 fitted in the hole 11 are fitted together and the adjusting screw 4 is screwed into the screw hole 13 of the fitting piece 10 from the outside by the injection hole 5, The tip cone portion 4 'pushes the coil spring 12 and the coil spring 12' in the middle of the contracted elasticity. In addition, the outer side of the fixing plate 14 is assembled by fixing the fixing ring 18 into the fixing groove 19 of the torque main body 1, and the moving pins 16 and 16 'are shown in FIGS. As shown in the figure, the torque main body 1 of the power transmission input shaft 3 and the disc 9 of the output shaft 3 'are integrally formed so that the power transmission input shaft 3 is integrated. In addition, the output shaft 3 'also becomes rotatable. Therefore, the work tool connected to the output shaft 3 'is also able to work under power transmission, and the present invention is subject to the resistance of the output shaft 3' due to a sudden overload from the work tool. Since the resistive force acts on the floating pins 16 and 16 'fitted to the both grooves 8 and 8' of the circular track 7, the floating pins 16 and 16 'are curved grooves ( 8), away from the (8 '), and rotates in the concave line of the circular orbit (7), so the output shaft (3') can be inverted regardless of the power transmission of the input shaft (3) has a safe effect against overload.
또한 본 고안은 토오크 본체(1)의 주입구멍(5)을 통하여 외부에서 조정나사(4)를 틀어넣거나 풀면, 원추부(4')가 양 코일스프링(12), (12')을 양측으로 수축시켜 유동핀(16), (16')에 강한 탄력을 받게 하거나, 약한 탄력을 받게 조정할 수 있으므로 농기구 트랙터의 동력이 크고 작은 것에 관계없이 토오크조정으로 편리하고 유효하게 사용할 수 있고 또 그 구조는 간단하며 마모가 없어 고장이 없고 장기간 안전하게 사용될 수 있는 이점이 있다.In addition, in the present invention, when the adjusting screw 4 is inserted or loosened from the outside through the injection hole 5 of the torque main body 1, the conical portion 4 'may move both coil springs 12 and 12' to both sides. It can be contracted to give strong elasticity to the floating pins 16 and 16 ', or weak elasticity, so it is convenient and effective to adjust the torque regardless of the power of the farm equipment tractor. It is simple and has no abrasion, so there is no trouble and can be used safely for a long time.
