Description
본 발명은 유류분배용 로타리펌프에 관한 것으로, 더욱 구체적으로는 로타리펌프의 흡입 및 토출효율을 향상시켜 유류분배효율을 높이고 회전자의 회전축을 단일축으로 구성하여 제조비용을 절감할수 있도록한 것이다.The present invention relates to a rotary pump for oil distribution, and more particularly, to improve the suction and discharge efficiency of the rotary pump to increase the oil distribution efficiency and to reduce the manufacturing cost by configuring the rotating shaft of the rotor as a single shaft.
일반적으로 유류분배용 로타리펌프는 몸체 내에 회전자가 편심설치되어 있고 수동핸들을 돌려서 회전자 안내날개에 의해 몸체 내에 진공 흡입력을 발생시킴으로서 흡입구를 통해 유류를 흡입한 다음 토출구로 보내지도록 되어 있다.In general, the rotary pump for oil distribution has an eccentric rotor installed in the body, and induces a vacuum suction force in the body by rotating the rotor guide blades by sucking the oil through the suction port and then sending it to the discharge port.
종래의 이러한 유류분배용 로타리펌프에서는 도 5에서와 같이 회전자(20)의 외주면(25)에 홈(25a)이 형성되어 있어서 몸체(10)의 내주면(11)에 스프링(24)으로 탄성지지된 회전자(20)의 안내날개(23)가 밀착되어 회전하면서 유류가 잔류된 상태로 회전하므로 진공상태를 만들때 홈(25a)에 잔류된 유류는 압축되어 진공흡입력이 떨어질뿐만 아니라 안내날개(23)가 슬라이드되는 접속홈(22) 중앙부분은 공간부(26)가 형성되어 그 공간부(26)에 유류가 내입되어 누압현상이 발생하므로 진공흡입력이 크게 떨어지게 되었으며, 회전자(20)의 양측에 회전축(21)(21')이 구비되어 일측 회전축(21')은 몸체(10)의 바닥면(14)에 형성된 회전축홈(15)에 지지되고 타측회전축(21)은 뚜껑체(30)에 지지되게한 것인바 이를 가공하는데 따른 제조비용이 많이들게 되었다.In the conventional oil distribution rotary pump, grooves 25a are formed on the outer circumferential surface 25 of the rotor 20, as shown in FIG. 5, and are elastically supported by the spring 24 on the inner circumferential surface 11 of the body 10. Since the guide blades 23 of the rotor 20 rotate in close contact with each other, the oil remains in the grooves 25a when the vacuum state is created, and thus the oil remaining in the grooves 25a is compressed to reduce the vacuum suction input as well as the guide wings 23. The central portion of the connecting groove 22, which slides), has a space portion 26 formed therein, and oil is introduced into the space portion 26 so that a pressure leakage occurs, so that the vacuum suction input is greatly decreased, and both sides of the rotor 20 are reduced. Rotating shafts 21 and 21 'are provided on one side of the rotating shaft 21' so as to be supported by the rotating shaft groove 15 formed in the bottom surface 14 of the body 10, and the other rotating shaft 21 is the lid 30. The manufacturing cost of processing it became expensive.
본 발명은 이러한 문제점을 해결하기 위하여 몸체 내에 편심설치된 회전자의 외주면이 몸체의 내주면에 밀착되게 구성하고 회전자의 회전축은 뚜껑체에만 지지된 단일축으로 구성하여서된 것이다.In order to solve this problem, the present invention is configured such that the outer circumferential surface of the rotor eccentrically installed in the body is in close contact with the inner circumferential surface of the body, and the rotating shaft of the rotor is composed of a single shaft supported only on the lid.

몸체(10) 내에 회전자(20)를 편심되게 설치하되 회전자(20)의 접속홈(22)에 스프링(24)으로 탄성지지시킨 양측의 안내날개(23)를 각각 끼우고 뚜껑체(30)를 볼트(32)로 결합한 다음 수동손잡이(26)로 회전자(20)를 회전시켜 유류를 흡입구(12)를 통해 진공흡입하여 토출구(13)로 토출이 이루어지도록한 유류분배용 로타리펌프에 있어서, 상기 회전자(20)의 외주면(25)을 원주형상으로 만들어 몸체(10)의 내주면(11)에 편심측이 밀착되게하고 안내날개(23)가 슬라이드되는 접속홈(22)은 차단벽체(22a)로 구성하고 회전자(20)의 회전축(21)은 단일축으로 구성하여 뚜껑체(30)에 길게 형성시킨 축관(31)에 끼워 지지되게한 것이다.The rotor 20 is installed eccentrically in the body 10, and the guide blades 23 of both sides elastically supported by the springs 24 are respectively inserted into the connection grooves 22 of the rotor 20, and the lid body 30. In the rotary pump for oil distribution in which the rotor (20) is combined with the bolt (32) and the rotor (20) is rotated with the manual handle (26) to suck the oil through the suction port (12) to discharge the discharge port (13). The connection groove 22 in which the outer circumferential surface 25 of the rotor 20 is formed in a circumferential shape and the eccentric side is in close contact with the inner circumferential surface 11 of the body 10 and the guide blade 23 slides is a blocking wall ( 22a) and the rotating shaft 21 of the rotor 20 is configured to be a single shaft to be fitted to the shaft tube 31 formed long in the lid 30.
또, 도 5는 몸체(10)의 토출구(13)에 나사부(Tapping)를 형성하지 않고 토출구(13)의 외주면에 호스(40)를 보조받침대(41)와 함께 직접 연결한 다음 체결구(42)로 고정시켜서된 것이다.In addition, FIG. 5 is a fastener 42 after directly connecting the hose 40 with the auxiliary support 41 to the outer circumferential surface of the discharge port 13 without forming a threading in the discharge port 13 of the body 10. It is fixed by).
이와같이된 본 발명은 몸체(10) 내에 편심설치된 회전자(20)를 수동손잡이(26)로 회전시키게 되면 도 4에서와 같이 몸체(10)의 우측 내주면(11)에원주형상으로된 회전자(20)의 외주면(25)이 밀착된 상태로 회전하게 되므로 회전자(20)의 외주면(25)이 밀착되는 부분에 안내날개(23)가 위치하게 될때는 안내날개(23)가 내측으로 슬라이드되어 회전자(20)의 안내날개(23)가 같은 원주상으로 밀착된 다음 안내날개(23)가 시계방향으로 회전하면서 서서히 돌출되어 흡입구(12)로 진공흡입된 유류를 토출구(13) 방향으로 보내게 된다.In the present invention as described above, when the rotor 20 eccentrically installed in the body 10 is rotated by the manual handle 26, the rotor is formed in a cylindrical shape on the right inner circumferential surface 11 of the body 10 as shown in FIG. Since the outer circumferential surface 25 of the 20 is rotated in close contact, the guide blade 23 is slid inward when the guide blade 23 is positioned in a portion where the outer circumferential surface 25 of the rotor 20 is in close contact. The guide blades 23 of the rotor 20 are brought into close contact with each other in the same circumference, and then the guide blades 23 rotate in a clockwise direction, gradually releasing the vacuum sucked oil to the suction port 12 toward the discharge port 13. It becomes.
이때, 본 발명의 회전자(20)의 외주면(25)은 원주형상으로 편심부분이 몸체(10)의 내주면(11)에 항상 밀착된 상태를 유지하게 되므로 흡입구(12)로 진공흡입된 유류가 토출구(13)로 완전토출되지 않고 역류되는 것을 차단함과 아울러 접속홈(22)은 차단벽체(22a)로 구성되어 유류가 내입될 염려가 없으므로 안내날개(23)에 의한 진공흡입력을 크게 향상시키게 된다.At this time, the outer circumferential surface 25 of the rotor 20 of the present invention is circumferential in shape so that the eccentric portion is always in close contact with the inner circumferential surface 11 of the body 10, the oil sucked into the vacuum inlet 12 In addition to blocking the flow back without being completely discharged to the discharge port 13, the connection groove 22 is composed of a blocking wall (22a), so that there is no fear that the oil can be introduced therein to greatly improve the vacuum suction input by the guide blade (23). do.
또, 도 5에서는 토출구(13)에 호스(40)를 연결할때 토출구(13) 외주면에 호스(40)와 호스꺽임을 방지하는 보조받침대(41)를 직접끼워 체결구(42)로 고정할수 있게 되는바, 이는 종래와 같이 토출구(13)에 나사부를 형성하여 파이프를 나사결합한 다음 파이프 끝단부에 호스를 체결구로 고정하는 번거로운 과정을 줄일수 있으므로 조립이 매우 편리하게 이루어진다.In addition, in FIG. 5, when the hose 40 is connected to the discharge port 13, the auxiliary support 41 which directly prevents the hose 40 and the hose from being bent on the outer circumferential surface of the discharge port 13 may be directly inserted to be fixed by the fastener 42. As it is, the assembly is very convenient because it forms a screw portion in the discharge port 13 as in the related art, and thus, a cumbersome process of fixing the hose to the pipe end with the fastener can be reduced.
한편, 회전자(20)의 회전축(21)은 뚜껑체(30)의 축관(31)에 지지된 단일축으로 구성되어 회전자(20)의 회전이 원활하게 이루어지고 몸체(10)의 바닥면에 축홈을 형성하거나 이에 따른 회전축을 구비하지 않아도 되기 때문에 제조공정을 줄여서 제조비용을 줄일수 있게된다.On the other hand, the rotating shaft 21 of the rotor 20 is composed of a single shaft supported on the shaft tube 31 of the lid 30, the rotation of the rotor 20 is made smoothly and the bottom surface of the body 10 Since it is not necessary to form an axial groove or a rotating shaft according to this, manufacturing costs can be reduced by reducing the manufacturing process.
이와같이 본 발명은 유류분배용 로타리펌프의 흡입 및 토출효율을 향상시켜 유류분배효율을 높이고 펌프의 제조비용을 절감할수 있는 이점이 있는 것이다.As described above, the present invention has the advantage of improving the suction and discharge efficiency of the oil distribution rotary pump to increase the oil distribution efficiency and reduce the manufacturing cost of the pump.
