Since the reverse rotation is not generated by the friction coefficient of the friction pad, the present invention relates to an anti-loosening structure of screw fastening means, which is effective for more effective fastening by being used in machine tools and automobiles with high vibration and impact.
Description
본 고안은 볼트 및 너트에 의한 나사 체결수단에 있어서, 체결부재와 볼트 및 너트간에 미끄럼이 발생하지 않도록 별도의 다각홈 및 다각패널 및 마찰부재를 함께 결합형성하므로서, 진동 및 충격이 심한 공작기계 및 자동차등에 적용함으로서 보다 안전성을 향상시키면서도 기기의 내구성을 향상시킬 수 있는 나사체결수단의 풀림방지구조에 관한 것이다.The present invention, in the screw fastening means by the bolt and nut, by forming a combination of a separate polygon groove, a polygon panel and a friction member together so as not to slip between the fastening member and the bolt and nut, machine tools and severe vibration and impact The present invention relates to an anti-loosening structure of screw fastening means that can improve the durability of the device while improving safety by applying to automobiles and the like.
일반적인 결합부재의 체결방법은 볼트 및 너트에 의한 체결방법이 널리 사용되고 있으며, 진동 및 충격이 가해지는 체결부위에는 다양한 풀림방지장치를 함께 결합하여 사용하므로서 기계의 작동중에 나사풀림이 발생치 않도록 하여 사용하고 있는 것이다.In general, the fastening method of bolts and nuts is widely used for fastening the fastening member, and the fastening part to which vibration and shock are applied is used by combining various loosening prevention devices together to prevent screw loosening during the operation of the machine. I'm doing it.
이러한 나사풀림방지수단으로는 볼트머리부에 스프링 와셔를 삽입하여 스프링 와셔의 탄발력에 의해 볼트 및 결합부재간을 이격탄설하고 있으므로 그 탄발력에 의해 볼트 및 너트의 역회전을 억제하는 방법이 사용되고 있으며,As the screw loosening prevention means, a spring washer is inserted into the bolt head to separate the bolt and the coupling member by the spring force of the spring washer. Therefore, the method of suppressing the reverse rotation of the bolt and nut by the spring force is used. And
또다른 방법으로는 볼트 또는 너트와 체결부재간의 경계면에 접착제를 투여하므로서 그 접착제에 의해 진동 및 충격에 의해서 풀리지 않게 한 방법이 사용되고 있다.In another method, an adhesive is applied to the interface between the bolt or nut and the fastening member, and the adhesive is not released by vibration and impact by the adhesive.
그러나, 전기한 바와 같은 스프링에 의한 풀림방지 방법은 결합부재와 볼트머리부의 사이에 삽입되는 것으므로 결합부재 및 스프링과의 슬립가능면적, 스프링 및 볼트머리부의 슬립가능면적이 동시에 발생하게 되므로, 그 역회전력이 스프링의 탄발력을 벗어나는 경우 급속하게 역회전하며 풀리는 문제점이 발생하였으며, 접착제에 의해 고정하는 방법 또는 접착제의 화학적 특성이 변하거나 충격으로부터는 안전하지 못하며, 다시 볼트를 풀고자 하는 경우에는 오히려 풀림이 불가능한 상태가 되는 문제점이 있는 것이다.However, as described above, the loosening prevention method by the spring is inserted between the coupling member and the bolt head, so that the sliptable area between the coupling member and the spring, and the sliptable area of the spring and the bolt head are simultaneously generated. When the reverse rotational power is out of the spring force of the spring, there is a problem of rapid rotation and loosening.The method of fixing by the adhesive or the chemical property of the adhesive is changed or unsafe from the impact, and the bolt is unscrewed again. Rather, there is a problem that becomes impossible to solve.
본 고안은 전기한 바와 같은 문제점을 제거코저 안출된 것으로서, 체결하고자 하는 체결부재의 일정위치에 다각홈을 형성하고, 이에 방사상으로 분할형성된 상향 탄력편을 갖는 다각패널 및 마찰패드를 삽입하고, 별도의 볼트 및 너트에 의해 체결부재를 결합하면 그 다각패널의 탄성에 의해 볼트 및 너트의 나사산을 완전밀착하므로 볼트의 역회전을 최대한 억제하게 되는 것이며, 진동이나 충격에 의해 볼트머리부가 미끄러지는 경우에는 그 마찰패드의 마찰계수에 의해 역회전이 발생하지 않게 되므로, 진동 및 충격이 심한 공작기계 및 자동차등에 적용사용하므로서 보다 효과적인 체결이 가능한 효과가 있는 나사체결수단의 풀림방지구조를 제공함에 본 고안의 목적이 있는 것이다.The present invention is conceived to eliminate the problems as described above, to form a polygonal groove in a predetermined position of the fastening member to be fastened, insert a polygonal panel and a friction pad having a radially divided upward elastic piece, and separately When the fastening member is joined by the bolt and nut of the bolt, the bolts and nuts of the bolt and nut are completely in contact with each other by the elasticity of the polygonal panel. Therefore, the reverse rotation of the bolt is suppressed as much as possible. The reverse rotation does not occur due to the friction coefficient of the friction pad, so that it can be applied to machine tools and automobiles with high vibration and impact, thereby providing an anti-loosening structure of screw fastening means, which has an effect that enables more effective fastening. There is a purpose.

도 1은 본 고안 나사체결수단의 풀림방지구조를 보인 분리사시도이고, 도 2는 체결전 상태를 보인 측단면설명도이다.1 is an exploded perspective view showing a loosening prevention structure of the present invention screwing means, Figure 2 is a side cross-sectional view showing a state before the fastening.
체결부재(1)(1')의 상부에 볼트공(2) 및 다각홈(3)을 형성하고, 그 다각홈(3)에 다각패널(4) 및 마찰부재(5)를 삽입형성하되,A bolt hole 2 and a polygonal groove 3 are formed in the upper part of the fastening member 1, 1 ', and the polygonal panel 4 and the friction member 5 are inserted into the polygonal groove 3, respectively.
다각패널(4)은 중앙에 전기한 볼트공(2)과 동일한 내경의 통공(6)을 형성하고 그 주면에 방사상으로 다수 분할형성된 탄력편(7)(7')을 상향형성하며,The polygonal panel 4 forms a through-hole 6 having the same inner diameter as the bolt hole 2, which is installed at the center, and upwardly forms the elastic pieces 7 and 7 'which are radially divided into the main surface thereof.
마찰부재(5)는 전기한 다각홈(3)에 삽입되며, 그 중앙부에는 전기한 볼트공(2)과 동일한 내경의 또다른 통공(8)을 형성하여 되는 것이다.The friction member 5 is inserted into the aforementioned polygonal groove 3, and is formed at the center thereof by forming another through hole 8 having the same inner diameter as the bolt hole 2 described above.
도면중 미설명 부호 10은 볼트머리, 11은 볼트나사부, 12는 너트이다.In the drawings, reference numeral 10 denotes a bolt head, 11 a bolt screw portion, and 12 a nut.
이상과 같은 구성에 의한 본 고안의 작용을 첨부도면에 의해 보다 상세히 설명하면 다음과 같다.Referring to the operation of the present invention by the configuration as described above in more detail by the accompanying drawings as follows.
먼저, 도 2의 도시와 같이 체결코저 하는 한쌍의 체결부재(1)(1')중 그 상부의 체결부재(1)의 일면에 다각홈(3)을 형성하고, 그 중앙부에는 볼트공(2)을 형성하여 되는 것이며, 그 다각홈(3)에 다각패널(4) 및 마찰부재(5)를 삽입하여 되는 것이다.First, as shown in FIG. 2, a polygonal groove 3 is formed on one surface of a fastening member 1 of a pair of fastening members 1 and 1 ′, and a bolt hole 2 is formed at a central portion thereof. ), And the polygonal panel 4 and the friction member 5 are inserted into the polygonal groove 3.
즉, 본 고안 나사체결수단의 풀림방지구조가 적용되는 요소는 자동차의 휠과 같이 주물제작되는 요소에 직접 다각홈(3)을 함께 형성할 수 있는 구조에 가장 적합한 것이며, 이외에도 비교적 기계적 강성이 뛰어나도록 제작된 사출물에도 적용사용 가능한 것이다.That is, the element to which the anti-loosening structure of the screw fastening means of the present invention is applied is most suitable for the structure capable of forming the polygonal groove 3 directly on the element manufactured by casting, such as a wheel of an automobile, and besides, the mechanical rigidity is excellent. It is also applicable to injection molded products.
이렇게 다각홈(2) 및 볼트공(2)이 형성된 체결부재(1)(1')에 통상의 볼트를 삽입하되, 그 볼트머리(10)가 전기한 마찰부재(5)측에 위치하도록 삽입하며, 그 반대쪽에는 너트(12)를 그 볼트나사부(11)에 삽입하여 고정하는 것이다.In this way, a conventional bolt is inserted into the fastening member 1 (1 ') in which the polygonal groove 2 and the bolt hole 2 are formed, and the bolt head 10 is inserted so as to be located at the friction member 5 side. On the opposite side, the nut 12 is inserted into the bolt screw portion 11 and fixed.
따라서, 도 2의 도시와 같이 다각패널(4)은 볼트 및 너트의 회전에 의해 체결부재(1)(1')가 조여지기 전에는 그 다각패널(4)의 상향 탄력편(7)(7')에 의해 마찰부재(5) 및 볼트머리(10)를 지지하고 있게 되는 것이며,Therefore, as shown in Fig. 2, the polygonal panel 4 is upwardly resilient pieces 7 and 7 'of the polygonal panel 4 before the fastening members 1 and 1' are tightened by the rotation of the bolts and nuts. By supporting the friction member 5 and the bolt head 10 by the),
도 3의 도시와 같이 볼트 및 너트를 더욱 조여 그 조임력이 탄력편(7)(7')의지지력을 이기게 되면 탄력편(7)(7')은 그 조임력에 의해 상부로 밀어내는 힘을 갖으며 수평상태가 되는 것이다.As shown in FIG. 3, when the tightening force is further tightened to overcome the support force of the elastic pieces 7 and 7 ′, the elastic pieces 7 and 7 ′ have a force to be pushed upward by the tightening force. And it becomes horizontal.
따라서, 그 탄력편(7)(7')에 의해 지속적으로 볼트머리(10) 및 너트(12)를 벌려주므로 그 탄성지지력에 의해 나사산이 더욱 밀착되며 마찰계수를 증가시키는 것이다.Therefore, the bolt head 10 and the nut 12 are continuously opened by the elastic pieces 7 and 7 ', so that the threads are more closely contacted by the elastic bearing force and the friction coefficient is increased.
따라서, 마찰계수의 증가에 의해 볼트 및 너트의 임의회전이 억제되면서도 진동이나 충격으로부터 보다 안전한 것이다.Therefore, while the arbitrary rotation of the bolt and nut is suppressed by the increase of the friction coefficient, it is safer from vibration or shock.
또한, 볼트머리(10)부와 직접적으로 접촉하는 마찰부재(5)는 유리섬유 또는 부직포와 같이 마찰계수가 뛰어난 재질로 형성하므로서, 진동이나 충격에 의해 볼트가 역회전하려는 힘을 억제하므로 보다 효율적인 볼트의 역회전 제어가 가능한 것이며,In addition, the friction member 5 which is in direct contact with the bolt head 10 is formed of a material having an excellent coefficient of friction, such as glass fiber or nonwoven fabric, and thus suppresses the force of the bolt to reverse rotation due to vibration or impact, thereby making it more efficient. The reverse rotation control of the bolt,
그 마찰부재(5) 또한 다각형상으로 제작하여 체결부재(1)의 다각홈(3)내에 삽입되어 있으므로 임의회전이 불가능 한 것이다.Since the friction member 5 is also made into a polygonal shape and inserted into the polygonal groove 3 of the fastening member 1, arbitrary rotation is impossible.
따라서, 사용자의 조임력에 의해 완전히 고정된 볼트 및 너트는 그 다각패널(4)의 탄성지지력 및 마찰부재(5)의 마찰계수에 의해 진동 및 충격으로부터 나사가 역회전하는 것으로 방지하며 보다 안전한 체결이 가능함은 물론, 견고한 체결에 의해 기계 및 장치의 수명을 연장시키는 것이다.Therefore, the bolts and nuts that are completely fixed by the user's tightening force prevent the screw from rotating back from vibration and impact due to the elastic support force of the polygon panel 4 and the friction coefficient of the friction member 5. It is possible, of course, to extend the life of the machine and apparatus by means of a secure fastening.
이상과 같은 본 고안 나사체결수단의 풀림방지구조는 다각패널의 탄성에 의해 볼트 및 너트의 나사산을 완전밀착하므로 볼트의 역회전을 최대한 억제하게 되는 것이며, 진동이나 충격에 의해 볼트머리부가 미끄러지는 경우에는 그 마찰패드의 마찰계수에 의해 역회전이 발생하지 않게 되므로, 진동 및 충격이 심한 공작기계 및 자동차등에 적용사용하므로서 보다 효과적인 체결이 가능한 효과가 있는 것이다.The loosening prevention structure of the screw fastening means of the present invention is to close the bolts and nuts of the bolts and nuts by the elasticity of the polygonal panel so that the reverse rotation of the bolts can be suppressed as much as possible. Since the reverse rotation does not occur by the friction coefficient of the friction pad, it is effective to enable more effective fastening by being applied to machine tools and automobiles with severe vibration and shock.
