Description
본 고안은 모터의 구동축과 스크류 바아 등의 피동축을 연결하는 벨로우즈 커플링에 관한 것으로서, 보다 상세하게는 벨로우즈부의 접합부에 복수개의 구멍이 형성되는 벨로우즈 커플링에 관한 것이다.The present invention relates to a bellows coupling connecting a drive shaft of a motor and a driven shaft such as a screw bar, and more particularly, to a bellows coupling in which a plurality of holes are formed at a junction of a bellows portion.
도 1a 및 도 1b을 참조하면, 종래의 제 1 실시예에 따른 벨로우즈 커플링은 허브(10)의 접합부(11)와 벨로우즈부(15)의 접합부(17)가 에폭시 접착제(19)에 의해 접합된다.1A and 1B, in a bellows coupling according to a first embodiment of the present invention, the junction 11 of the hub 10 and the junction 17 of the bellows 15 are joined by an epoxy adhesive 19. do.
그러나, 상기 벨로우즈 커플링은 허브(10)의 접합부(11)의 외주면과 벨로우즈부(15)의 접합부(17)의 내주면만이 서로 접착되기 때문에 접합강도가 약한 단점이 있어, 축의 비틀림 응력에 의해 접합부위가 떨어질 수 있는 문제점이 있었다.However, the bellows coupling has a weak joint strength because only the outer circumferential surface of the junction portion 11 of the hub 10 and the inner circumferential surface of the junction portion 17 of the bellows portion 15 are bonded to each other. There was a problem that the junction can fall.
도 2a 및 도 2b를 참조하면, 종래의 제 2 실시예에 따른 벨로우즈 커플링은 허브(20)의 안쪽 수직면(21)에 접합홈(23)이 성형되고, 상기 접합홈(23)에 벨로우즈부(30)의 접합부(31)가 끼워진 후, 에폭시 접착제(40)가 상기 접합홈(23)에 채워져 허브(20)의 접합홈(23)과 벨로우즈부(30)의 접합부(31)가 접합된다.2A and 2B, in the bellows coupling according to the second exemplary embodiment, a joining groove 23 is formed in an inner vertical surface 21 of the hub 20, and a bellows part is formed in the joining groove 23. After the joining portion 31 of the 30 is inserted, the epoxy adhesive 40 is filled in the joining groove 23 to join the joining groove 23 of the hub 20 and the joining portion 31 of the bellows portion 30. .
상기 벨로우즈 커플링은 벨로우즈부의 접합부의 내주면 및 외주면이 에폭시 접착제에 의해 접합홈의 외측벽면 및 내측벽면에 접합되기 때문에 접합강도가 제 1 실시예에 따른 벨로우즈 커플링 보다 개선되었지만, 허브와 벨로우즈부의 접합강도 보강은 여전히 요구되고 있다.Although the bellows coupling has improved joint strength than the bellows coupling according to the first embodiment because the inner circumferential surface and the outer circumferential surface of the joint portion of the bellows portion are joined to the outer wall surface and the inner wall surface of the joining groove by an epoxy adhesive, the junction between the hub and the bellows portion is improved. Strength reinforcement is still required.
따라서, 본 고안의 목적은 벨로우즈부의 접합부에 복수개의 구멍을 형성하여 벨로우즈부의 접합부가 허브의 접합홈에 에폭시 접착제에 의해 접합될 때, 상기 에폭시 접착제가 접합부의 구멍에 채워지므로서, 에폭시 접착제가 굳은 후, 상기 구멍에 채워진 부분이 핀역할을 하므로서 접합부와 접합홈의 접합강도가 더 보강되는 벨로우즈 커플링을 제공하는 것이다.Therefore, an object of the present invention is to form a plurality of holes in the junction of the bellows portion, when the junction of the bellows portion is bonded to the bonding groove of the hub by the epoxy adhesive, the epoxy adhesive is filled into the hole of the junction portion, the epoxy adhesive is hardened After that, the portion filled in the hole serves as a pin to provide a bellows coupling to further strengthen the joint strength of the joint and the joint groove.

상기와 같은 목적을 달성하기 위한 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.
도 3 및 도 4를 참조하면, 본 고안에 따른 벨로우즈 커플링은 허브(50)의 안쪽 수직면(51)에 형성된 접합홈(53)에 벨로우즈부(60)의 접합부(61)가 끼워진 후, 에폭시 접착제(70)가 상기 접합홈(53)에 채워지므로서, 상기 에폭시 접착제(70)에 의해 허브(50)의 접합홈(53)과 벨로우즈부(60)의 접합부(61)가 접합된다.3 and 4, the bellows coupling according to the present invention, after the joint 61 of the bellows portion 60 is fitted into the joint groove 53 formed in the inner vertical surface 51 of the hub 50, epoxy As the adhesive 70 is filled in the joining groove 53, the joining groove 53 of the hub 50 and the joining portion 61 of the bellows part 60 are joined by the epoxy adhesive 70.
상기 벨로우즈부(60)의 접합부(61)에는 복수개의 구멍(63)이 형성된다. 이것에 의해, 벨로우즈부(60)의 접합부(61)가 허브(50)의 접합홈(53)에 에폭시 접착제(70)에 의해 접합될 때, 상기 에폭시 접착제(70)가 접합부(61)의 구멍(63)에 채워지므로서, 접합부(61)의 내주면 및 외주면이 에폭시 접착제에 의해 접합홈의 외측벽면 및 내측벽면에 접합될 뿐만 아니라, 에폭시 접착제(70)가 굳은 후, 상기 구멍(63)에 채워진 에폭시 접착제(70)가 핀역할을 하므로서 접합부(61)와 접합홈 (53)의 접합강도가 더 보강된다.A plurality of holes 63 are formed in the junction portion 61 of the bellows portion 60. As a result, when the bonding portion 61 of the bellows portion 60 is bonded to the bonding groove 53 of the hub 50 by the epoxy adhesive 70, the epoxy adhesive 70 is a hole of the bonding portion 61. The inner peripheral surface and the outer peripheral surface of the joining portion 61 are not only bonded to the outer wall surface and the inner wall surface of the joining groove by the epoxy adhesive, but also the epoxy adhesive 70 is hardened, so as to be filled in the hole 63. As the filled epoxy adhesive 70 serves as a pin, the bonding strength of the bonding portion 61 and the bonding groove 53 is further reinforced.
위에서 설명한 바와같이, 본 고안에 따른 벨로우즈 커플링은 벨로우즈부의 접합부의 내주면 및 외주면이 에폭시 접착제에 의해 접합홈의 외측벽면 및 내측벽면에 접합될 뿐만 아니라, 에폭시 접착제가 굳은 후, 벨로우즈부의 접합부의 구멍에 채워진 에폭시 접착제가 핀역할을 하므로서 접합부와 접합홈의 접합강도가 더 보강되는 효과가 있다.As described above, the bellows coupling according to the present invention is not only the inner and outer circumferential surfaces of the joint of the bellows joint are joined to the outer wall and the inner wall of the joining groove by epoxy adhesive, but also the hole of the joint of the bellows joint after the epoxy adhesive is hardened. Epoxy adhesive filled in the role of the pin has the effect of further strengthening the joint strength of the joint and the groove.
