상기한 구성으로 이루어진 본 발명은, 도시안된 펌프로부터 그리스가 가압공급되는 그리스 공급호스(32)를 연결부재(31)에 의해 베어링 받침대(5)의 그리스 주입공(2)에 연결하므로써 베어링 받침대(5)를 경유하여 그리스 주입축(10)으로 공급되는데, 그리스 공급호스(32)의 중간부 위에 링크(33A)의 희동에 의해 그리스의 공급이 단속되는 개폐밸브(33)를 개재하고 상기한 개폐밸브(33)의 링크(33A)에 레버(34)를 연결하므로써 레버(34)의 전,후동에 의해 그리스의 공급이 단속되도록 한다.According to the present invention having the above-described configuration, the grease supply hose 32 through which grease is pressurized from a pump (not shown) is connected to the grease injection hole 2 of the bearing pedestal 5 by the connecting member 31. 5) is supplied to the grease injection shaft 10 via the on / off valve 33 where the supply of grease is interrupted by the movement of the link 33A on the middle of the grease supply hose 32. By connecting the lever 34 to the link 33A of the valve 33, the supply of grease is interrupted by the forward and backward movement of the lever 34.

상기한 구성으로 이루어진 본 발명에 의한 베어링용 그리스 주입장치의 동작관계를 이하 제4도에 의해설명한다.An operation relationship of the bearing grease injection device according to the present invention having the above-described configuration will be described with reference to FIG. 4.

베어링(B)의 윤활을 위해 내부에 그리스를 주입시킬 때에는 제4도의 (a)도와 같이 베어링(B)의 이너 레이스 내측으로 그리스 주입축(10)을 삽입시키고 베어링(B)의 하부 주연이 베어링 받침대(5)의 커버(3) 내측에 지지되도록 장착한 다음 복동실린더(15)를 작동시키면 로드(11)의 하강에 따라 가압판(25)이 하강하여 베어링(B)을 상부로부터 가압고정시키게 된다.When grease is injected into the inside for lubrication of the bearing B, the grease injection shaft 10 is inserted into the inner race of the bearing B as shown in FIG. After mounting the support 5 inside the cover 3 of the pedestal 5 and operating the double-acting cylinder 15, the pressure plate 25 descends according to the lowering of the rod 11 to press-fit the bearing B from the top. .

상기한 과정후 레버(34)를 작동시키면 개폐밸브(33)가 개방되므로써 제4도의 (b)도와 같이 그리스(G)가 그리스 주입공(2)을 통해 가압 공급되며, 이에 따라 그리스(G)는 그리스 주입축(10)의 그리스 유입공(6)을 경유하여 그리스 유출공 (7)으로 유출되어 그리스 주입축(10)과 베어링 받침대(5)의 커버(3)내에 충진된다.When the lever 34 is operated after the above-described process, the on / off valve 33 is opened so that the grease G is pressurized and supplied through the grease injection hole 2 as shown in FIG. Is discharged to the grease outlet hole (7) via the grease inlet hole (6) of the grease injection shaft (10) and filled in the grease injection shaft (10) and the cover (3) of the bearing pedestal (5).

이때, 그리스 주입축(10)과 커버(3)사이의 개방된 공간 사이에는 베어링(B)이 장착되어 있으므로 그리스(G)는 외부로 누출되지 않고 베어링(B)의 내부에 원활히 충진되며, 그리스(G)의 충진이 완료되면 개폐밸브(33)를 차단하고 복동실린더(15)의 로드(11)를 상부로 위치시킨 후 베어링(B)을 이탈시키므로써 그리스 주입작업을 완료한다.At this time, since the bearing B is mounted between the open space between the grease injection shaft 10 and the cover 3, the grease G is smoothly filled in the inside of the bearing B without leaking to the outside. When the filling of (G) is completed, the on / off valve 33 is shut off, the rod 11 of the double-acting cylinder 15 is positioned upward, and the bearing B is detached to complete the grease injection operation.

상기한 바와 같이 실시하는 본 발명은 베어링(B)의 윤활을 위한 그리스의 주입작업이 신속하고 용이하게 이루어지므로써 작업시간과 인력을 절감할 수 있으며, 그리스의 주입효율이 높아 그리스의 손실을 방지하고 베어링(B)의 윤활이 완활히 이루어지므로써 베어링(B)의 수명을 증대시키는 효과가 있다.The present invention carried out as described above can reduce the working time and manpower because the operation of injecting grease for lubrication of the bearing (B) can be made quickly and easily, and the grease injection efficiency is high to prevent loss of grease. And since the lubrication of the bearing (B) is made smoothly, there is an effect of increasing the life of the bearing (B).
