Abstract

〔목적〕〔purpose〕

주구동기어와 피동기어, 부구동기어와 피동기어간의 접촉점이 불일치한 경우 구동축이 회전하는 초기에 불일치된 접촉점을 일치시켜 고속회전축을 정상적으로 고속회전시킬 수 있고, 또한 회전시 과열로 인한 디스크의 변형방지에 유효한 고속회전축 지지장치를 제공하기 위한 것이다.If the contact points between the main drive gear, the driven gear, the sub drive gear, and the driven gear are inconsistent, it is possible to make the high-speed rotation shaft rotate at a high speed by matching the incoincident contact points at the initial stage of rotation of the drive shaft, And to provide a high-speed rotating-shaft support apparatus which is effective for preventing the above-

〔구성〕〔Configuration〕

소형 피동기어(a)를 가진 고속회전축(1)을 중심으로 그 주위의 삼각지점에 전동기어(e) 그리고 주구동기어(b) 및 디스크(5)가 설치된 구동축(2)과 중동 기어 (f) 그리고 부구동기어(c) 또는 (d) 및 디스크(5)가 설치된 종동축(3,4)을 설치하여 주구동기어(b)와 부구동기어(c,d)는 피동기어(a)에 동시 접속하고 전동기어(e)와 종동기어(f)는 아이들러(g)로 접속하며 또한 각 디스크(5)를 고속회전축(1)의 외주면에 접촉시켜 지지하게 한 것에 있어서, 전동기어(e)는 구동축(2)에 그리고 각 종동기어(f)는 그들의 종동축(3,4)에 고정축 끼움하되 판면에 적어도 하나 이상의 핀공 (11)을 뚫고 주구동기어(b) 또는 부구동기어(c,d)쪽으로 빠져나오게 핀(12)을 박아 고정하고, 주구동기어(b)와 각 부구동기어(c,d)의 판면에는 상기 핀공(11)과 같은 위치에 중심을 맞춰 부싱공(13)을 천공하고, 각 부싱공(13)마다 탄성부싱(14)을 삽입해 고정한 다음 각 탄성부싱(14)에는 그 위치의 핀(12)을 탄력적으로 끼워 맞추고, 디스크(5)는 방사상으로 슬리트(6)을 형성하고, 원주면에는 테(7)을 둘러붙이며, 상, 하면의 적어도 1면 이상에 동심원 상으로 홈(8)을 형성한 것이다.A driving shaft 2 and a middle gear f (f) provided with a transmission gear e, a main drive gear b and a disk 5 at a triangular point around the high speed rotary shaft 1 having the small driven gear a, The main drive gear b and the sub drive gears c and d are driven by the driven gear a by providing the subordinate drive gear c or d and the driven shaft 3 or 4 provided with the disk 5, And the transmission gears e and the driven gears f are connected by an idler g and the disks 5 are held in contact with the outer peripheral surface of the high-speed rotary shaft 1, ) And the driven gears (f) are fixed to the driven shafts (3, 4) by inserting at least one or more pin holes (11) in the surface of the drive shaft (2) d and the center of the pin hole 11 is centered on the surface of the main drive gear b and each of the sub drive gears c and d so that the bushing balls 13) The elastic bushing 14 is inserted and fixed for each of the bushing holes 13 and the resilient bushing 14 resiliently fits the pin 12 at that position, And a groove 7 is formed on the circumferential surface thereof and grooves 8 are formed concentrically on at least one surface of the upper and lower surfaces.
