Description
본 고안은, 진동 등으로 체결부가 헐거워지는 것을 방지하기 위하여 사용되어지는 록 너트에 관한 것으로, 특히 록 너트의 풀림방지부를 개량하여 안정된 록킹을 도모할 수 있는 록 너트에 관한 것이다.The present invention relates to a lock nut that is used to prevent the fastening portion from loosening due to vibration and the like, and more particularly, to a lock nut capable of achieving stable locking by improving the loosening prevention portion of the lock nut.
일반적으로 산업기기 또는 차동차의 구동부 즉, 진동이 발생되어지는 부위의 부품을 볼트와 너트를 이용하여 체결할 때에는 진동에 의한 너트의 풀림현상을 방지할 수 있도록 볼트에 두개의 너트를 체결하여 풀림현상을 방지하게 된다.Generally, when fastening parts of industrial equipment or parts of a differential vehicle, that is, parts where vibration is generated by using bolts and nuts, loosening phenomenon is caused by fastening two nuts to bolts to prevent loosening of nuts due to vibration. Will be prevented.
한편, 너트의 본체에 별도 풀림방지부를 형성한 너트를 사용하기도 한다.On the other hand, it is also possible to use a nut formed in the main body of the nut to prevent the loosening.
도1은 종래 기술에 의한 록 너트의 사시도 이다.1 is a perspective view of a lock nut according to the prior art.
도1은 록 너트의 일 실시예로서, 록 너트(10)는 통상적인 형상의 모양을 가지는 너트 본체(11)의 측면에 풀림방지부(12)를 형성한 것이다.1 shows an embodiment of the lock nut, in which the lock nut 10 is provided with an anti-loosening part 12 on the side of the nut body 11 having a shape of a conventional shape.
상기한 록 너트(10)를 볼트에 체결하기 전에 풀림방지부(12)를 별도의 공구를 가지고 타원형상으로 변형시킨다.Before the lock nut 10 is fastened to the bolt, the release preventing portion 12 is deformed into an elliptical shape with a separate tool.
상기와 같이 풀림방지부(12)가 변형되어진 상태에서 볼트에 록 너트(10)를 체결하면, 타원형상으로 변형된 풀림방지부(12)가 볼트의 나사산을 마모시키면서 체결되어지게 되는 것이다.When the lock nut 10 is fastened to the bolt in the state in which the loosening prevention part 12 is deformed as described above, the loosening prevention part 12 deformed into an elliptical shape is fastened while wearing the thread of the bolt.
상기와 같은 종래의 록 너트는 풀림방지부를 변형시키는데 어려움이 있어 작업 생산성 향상에 어려움이 있었고, 풀림방지부가 규격화 되어 있어 그 활용범위에 제약이 있었으며, 록 너트의 풀림방지부 변형에 어려움이 있어 록 너트의 대형화에 어려움이 있었다.The conventional lock nut as described above has a difficulty in improving work productivity due to difficulty in deforming the anti-loosening part, and the anti-loosening part is standardized, thereby limiting its use range, and having difficulty in deforming the anti-loosening part of the lock nut. There was a difficulty in the enlargement of the nut.
본 고안의 목적은, 통상의 형상을 가지는 본체에 슬롯으로 분활되어지고, 내경에 나사산을 가지며, 그리스저장홈이 형성된 것으로서, 록 너트의 조임 토큐를 향상시켜 록 너트의 신뢰성을 도모할 수 있고, 풀림방지부에 나사산을 형성함으로서 볼트의 손상을 방지할 수 있으며, 록 너트의 사이즈를 다양화할 수 있는 록 너트를 제공하는 데 있다.The object of the present invention is that the main body having a normal shape is divided into slots, has a screw thread in the inner diameter, and a grease storage groove is formed, which improves the tightening torque of the lock nut, thereby achieving reliability of the lock nut. The present invention provides a lock nut that can prevent a bolt from being damaged by forming a thread in a loosening prevention portion and can vary the size of the lock nut.

이러한 본 고안의 목적은, 통상의 형상을 가지는 너트 본체(110)의 측면에 돌출되어져서 슬롯(121)에 의해 분활되어져 있고, 내면에 나사산(122)이 형성되어 있는 풀림방지부(120)와;The object of the present invention is to protrude to the side of the nut main body 110 having a normal shape and divided by the slot 121, and the anti-loosening portion 120 is formed with a thread 122 on the inner surface; ;
상기 풀림방지부(120)의 나사산(122)과 본체(110)의 나사산(111) 사이에 체결에 따른 마찰 영향을 줄일 수 있도록 그리스저장홈(130)을 가지는 것에 의해 달성된다.It is achieved by having a grease storage groove 130 so as to reduce the frictional effect of the fastening between the thread 122 of the loosening prevention portion 120 and the thread 111 of the main body 110.
이하, 본 고안의 바람직한 실시예를 명세서에 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도2는 본 고안에 따른 록 너트의 사시도 이고, 도3은 도2의 단면도 이다.Figure 2 is a perspective view of the lock nut according to the present invention, Figure 3 is a cross-sectional view of FIG.
도시된 바와 같이, 본 고안에 따른 록 너트(100)를 볼트(200)에 도3에서와 같이 체결한다.As shown, fastening the lock nut 100 according to the present invention to the bolt 200 as shown in FIG.
상기한 록 너트(100)를 볼트(200)에 체결하기 이전에 그리스저장홈(130)에 그리스를 충진 한다.Grease is filled in the grease storage groove 130 before the lock nut 100 is fastened to the bolt 200.
상기와 같이 그리스가 충진되어지면 볼트(200)에 본체(110)부터 체결하게 되고, 본체(110)에 형성된 풀림방지부(120)가 볼트(200)와 체결되어질 때에는 풀림방지부(120)가 슬롯(121)에 의해 절결되어 있어서 볼트(200)의 사이즈에 대응되게 벌어지면서 내면에 형성된 나사산(122)이 나사결합 되면서 장착되어 진다.When grease is filled as described above, the bolt 200 is fastened from the main body 110, and when the anti-loosening part 120 formed on the main body 110 is fastened with the bolt 200, the anti-loosening part 120 is closed. It is cut out by the slot 121 and is mounted while being screwed to the thread 122 formed on the inner surface while opening corresponding to the size of the bolt 200.
이때, 그리스저장홈(130)에 저장된 그리스에 의해 록 너트(100)가 볼트(200)에 원활하게 조여지게 되는 것이다.At this time, the lock nut 100 is smoothly tightened to the bolt 200 by the grease stored in the grease storage groove 130.
이상과 같은 본 고안은 상술한 특성의 바람직한 실시예에 한정되지 아니하며 청구범위에서 청구하는 본 고안의 요지를 벗어남 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다.The present invention as described above is not limited to the preferred embodiment of the above-described characteristics, anyone of ordinary skill in the art to which the subject innovation belongs without departing from the gist of the present invention claimed in the claims will be able to implement various changes. .
상기된 바와 같이 본 고안에 따른 록 너트는, 통상의 형상을 가지는 본체에 슬롯으로 분활되어지고, 내경에 나사산부를 가지며, 그리스저장홈이 형성된 것으로서, 록 너트의 조임 토큐를 향상시켜 록너 너트의 신뢰성을 도모할 수 있고, 풀림방지부에 나사산을 형성함으로서 볼트의 손상을 방지할 수 있으며, 록 너트의 사이즈를 다양화할 수 있도록 한 매우 유용한 고안인 것이다.As described above, the lock nut according to the present invention is divided into a slot in a main body having a normal shape, has a threaded portion in an inner diameter, and a grease storage groove is formed, which improves the tightening torque of the lock nut, thereby improving reliability of the locker nut. It is possible to achieve, to prevent the damage of the bolt by forming a thread in the loosening prevention portion, it is a very useful design to be able to vary the size of the lock nut.
