Description

풀림방지용 볼트와 너트의 체결구조 {The Combining Structure Of The Nut and Unlock Prevention Type Bolt}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening bolt and a fastening bolt,

본 발명은 풀림방지용 볼트와 너트의 체결구조에 관한 것으로, 더욱 상세하게는 회전부재의 체결시 진동이나 유동에 의해 볼트와 너트 사이에 체결력이 약하져서 너트가 풀리는 것을 방지할 수 있는 풀림 방지용 볼트와 너트의 체결구조에 관한 것이다.The present invention relates to a fastening bolt and a nut fastening structure for preventing loosening, and more particularly, to a bolt fastening bolt and a bolt fastening bolt which can prevent a nut from being loosened due to weakening of a fastening force between a bolt and a nut due to vibration or flow when a rotary member is fastened. To a nut fastening structure.

일반적으로 볼트는 너트와 더불어 두 개의 구조체를 결합시키거나, 구조체 자체에 형성된 나사산으로 이루어진 체결공에 다른 결합체를 관통하여 체결하는 체결구로서 사용된다. 상기 볼트는 체결용으로는 싱글 너트만으로 제품을 고정하는 경우가 대부분이며, 확실한 고정이 필요하다고 느끼는 곳에는 두 개으 너트를 사용하는 더블 너트를 사용하게 된다.Generally, a bolt is used as a fastener for coupling two structures together with a nut, or for fastening another fastener through a fastener made of a screw thread formed in the structure itself. Most of the bolts are fastened with only a single nut, and double nuts using two nuts are used in places where it is necessary to securely fix the bolts.

이와 같이, 볼트와 너트는 서로 나사 체결하여 두 부재를 결합시키게 된다.Thus, the bolt and the nut are screwed together to join the two members.

볼트와 너트는 체결 전에 즉, 너트가 볼트의 나선부에 나사 결합되어 있는 상태에서는 너트의 나사산과 볼트의 나사산 사이에 형성되는 틈새를 통해서 너트가 볼트의 나선부에서 회전하면서 이동된다. 이후에, 볼트와 너트 사이에 완전히 체결이 완료되면,볼트의 나사산과 너트의 나사산은 그 일측면이 상호 밀착되면서 마찰력이 발생되고 이 마찰력이 볼트와 너트의 체결력의 일부를 담당하게 된다.The bolts and nuts are moved while rotating in the spiral part of the bolt through the gap formed between the thread of the nut and the thread of the bolt before the fastening, that is, when the nut is screwed to the thread of the bolt. Thereafter, when the tightening between the bolt and the nut is completed, the thread of the bolt and the nut of the nut are brought into contact with each other and friction force is generated, and this frictional force takes part of the fastening force of the bolt and nut.

즉, 볼트는 체결 토크가볼트의 헤드부와 체결용 부품 사이의 마찰50%, 볼트의 나사산과 너트의 나사산 마찰 50%, 볼트의 축방향 체결력 10% 비율로 분배되어 각 부분의 체결력에 의해 체결이 유지되도록 구성된다.That is, the bolts are distributed in a ratio of 50% of the friction between the head part of the bolt and the fastening part, 50% of the thread friction of the bolt thread and the nut, and 10% of the axial fastening force of the bolt, Is maintained.

그러나, 볼트와 너트가 체결된 부위에 진동이 발생하게 되면,축력이 사라지고,이에 따라 볼트의 나사산과 너트의 나사산 사이에 마찰력이 감소되면서 볼트 풀림이 발생하게 되는 문제점이 있었다.However, when vibration occurs at a portion where the bolt and the nut are fastened, the axial force disappears, thereby causing the bolt to loosen as the frictional force decreases between the thread of the bolt and the thread of the nut.
