먼저, 소정형상의 풀리(11)의 연결관(11a)에 측방으로 관통공(11b)을 형성한 다음, 모터(미도시)에 의해 회전되는 구동축(12)에 연결관(11a)의 관통공(11b)과 대응되는 통공(12a)을 형성하여 소정길이의 고정핀(12b)으로서 관통공(11b)과 통공(12a)을 관통시킨 다음 고정와셔(12c)로 고정시킨다.First, the through hole 11b is formed laterally in the connecting pipe 11a of the pulley 11 of a predetermined shape, and then the through hole of the connecting pipe 11a is formed in the drive shaft 12 rotated by a motor (not shown). A through hole 12a corresponding to 11b is formed to pass through hole 11b and through hole 12a as a fixing pin 12b of a predetermined length, and then fixed with a fixing washer 12c.
또한, 상기 구동축(12)의 하단부에 체결공(미도시)을 형성한 다음, 상기 체결공에 고정볼트(13)를 체결시킨다.In addition, after forming a fastening hole (not shown) in the lower end of the drive shaft 12, and fastening the fixing bolt 13 to the fastening hole.
이때, 상기 연결관(11a)의 하단부에 고정볼트(13)가 접촉되는데, 상기 연결관(11a)의 하단부와 고정볼트(13) 사이에 링형상의 진동흡수부재(13a)를 설치하여 구동축(12)으로부터 전달되는 진동을 흡수시킨다.At this time, the fixing bolt 13 is in contact with the lower end of the connecting pipe (11a), a ring-shaped vibration absorbing member (13a) is installed between the lower end of the connecting pipe (11a) and the fixing bolt 13 drive shaft ( 12) Absorb the vibration transmitted from.
이상의 설명은 본 고안의 일 실시예에 불과하며, 본 고안의 구성은 그 요지범위 내에서 얼마든지 그 변경이 가능하다.The above description is only one embodiment of the present invention, the configuration of the present invention can be changed any number within the scope of the subject matter.
상기와 같이 구성된 본 고안의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the subject innovation configured as described above in detail.
상기 풀리(11)를 구동축(12)에 결합시키고자 하면, 도 2와 같이 구동축(12)에 풀리(11)의 연결관(11a)을 끼운 다음, 상기 연결관(11a)의 관통공(11b)과 구동축(12)의 통공(12a)을 고정핀(12b)으로서 관통시킴과 동시에 상기 관통공(11b)의 측방으로 돌출된 고정핀(12b)의 양측 단부에 고정와셔(12c)를 끼움고정시킨다.When the pulley 11 is to be coupled to the drive shaft 12, the connector 11a of the pulley 11 is inserted into the drive shaft 12 as shown in FIG. 2, and then the through hole 11b of the connector 11a is provided. And the fixing washer 12c is inserted into both ends of the fixing pin 12b protruding to the side of the through hole 11b while penetrating the through hole 12a of the drive shaft 12 as the fixing pin 12b. Let's do it.
그런 다음, 연결관(11a)의 하단부에 진동흡수부재(13a)을 결합시킨 상태에서 구동축(12) 하단부에 체결공에 고정볼트(13)를 체결시킨다.Then, the fixing bolt 13 is fastened to the fastening hole in the lower end of the drive shaft 12 in a state in which the vibration absorbing member 13a is coupled to the lower end of the connecting pipe 11a.
이때, 상기 진동흡수부재(13a)는 구동축(12)으로부터 전달되는 진동을 흡수시키게 된다.At this time, the vibration absorbing member 13a absorbs the vibration transmitted from the drive shaft 12.
따라서, 본 고안은 상기 풀리(11)의 연결관(11a) 측방에서 구동축(12)으로 고정핀(12b)을 관통시킨 다음, 상기 구동축(12) 하단부의 체결공에 고정볼트(13)를 결합시켜 풀리(11)와 구동축(12)을 상호 고정시키므로서 풀리(11)와 구동축(12)의 고속회전시 고정볼트(13)가 해제되는 것을 방지하는 한편, 상기 연결관(11a)의 하단부와 고정볼트(13) 사이에 진동흡수부재(13a)를 설치하여 구동축(12)에서 풀리(11)로 전달되는 진동을 극소화시킨 효과가 있다.Therefore, the present invention penetrates the fixing pin 12b into the driving shaft 12 from the side of the connecting pipe 11a of the pulley 11, and then couples the fixing bolt 13 to the fastening hole of the lower end of the driving shaft 12. By fixing the pulley 11 and the drive shaft 12 to each other to prevent the fixing bolt 13 is released during the high speed rotation of the pulley 11 and the drive shaft 12, while the lower end of the connecting pipe (11a) and The vibration absorbing member 13a is installed between the fixing bolts 13 to minimize the vibration transmitted from the drive shaft 12 to the pulley 11.
