Abstract
본 고안은 종래의 피스톤 펌프는 구조가 복잡하고 부품수가 많아 생산단가는 고가이면서 효율은 저하되었고 베인(Vane)펌프는 항시 베인(Vane)이 시린더의 벽을 압축하였으므로 마찰저항이 증가하고 마모가 심해 수명이 단축되는 단점이 있었으며 기어펌프인 경우에는 기어가 서로 치함되어 회전하므로써 전술한 피스톤 펌프나 베인(Vane)펌프보다 마모가 더 심하고 펌핑시 효율이 저하되는 등의 폐단을 해결하기 위해 실린더 중앙의 로터내입공과 둘레에 회전밸브내입부를 연통시켜 로더 외둘레에 돌설된 다수개의 장돌부를 회전밸브의 내입장홈에 끼워 회전이 용이하게 하고 회전축에 고정된 대기어는 치합된 회전밸브 단부의 소기어를 연동하여 흡입된 오일을 회전밸브와 로터의 표면이 밀착되어 고도의 기밀을 유지하는 과정이 계속 반복되면서 흡입, 토출시킬때에 마찰저항을 받지 않게 하므로써 고장률이 없고 성능이 우수한 제품을 저렴한 가격으로 생산하여 반영구적으로 사용할 수 있도록 고안한 것임.According to the present invention, the conventional piston pump has a complicated structure and a large number of parts, resulting in high production cost and low efficiency. The vane pump always compresses the wall of the cylinder to increase frictional resistance and wear. In the case of the gear pump, the gears are rotated by rotating each other in the case of the gear pump, so that the abrasion is more severe than the piston pump or vane pump described above and the efficiency of the pump is reduced. The inner rotor of the rotor and the inner part of the rotary valve communicate with each other, so that a plurality of long protrusions protruding from the outer circumference of the loader are inserted into the inner groove of the rotary valve to facilitate rotation. As the surface of the rotary valve and the rotor is closely adhered to each other, the process of maintaining high air tightness is repeated. It is designed to be used semi-permanently by producing a product with no failure rate and excellent performance at a low price by not receiving frictional resistance when discharging.

본 고안은 롤-베인(Roll-Vane)형 유압펌프에 관한 것이다.The present invention relates to a roll-vane type hydraulic pump.
종래의 피스톤 펌프는 구조가 복잡하고 부품수가 많아 생산단가는 고가이면서 효율은 저하되었고 베인펌프는 항시 베인 시린더의 벽을 압축하였으므로 마찰저항이 증가하고 마모가 심해 수명이 단축되는 단점이 있었으며, 기어펌프인 경우에는 기어가 서로 치합되어 회전하므로써 전출한 피스톤 펌프나 베인펌프보다 마모가 더 심하고 펌핑시 효율이 저하되는 등의 폐단이 있었다.The conventional piston pump has a disadvantage in that the structure is complicated and the number of parts is high, the production cost is high and the efficiency is lowered. The vane pump always compresses the wall of the vane cylinder, which increases frictional resistance and severe wear and shortens the life. In the case of the pump, the gears are engaged with each other to rotate, resulting in more abrasion than the piston pump or vane pump moved out and the efficiency of pumping.
본 고안은 상기와 같은 폐단을 해결하기 위해 시린더 중앙의 로터내입공과 둘레에 회전밸브 내입부를 연통시켜 로터 외둘레에 돌설된 다수개의 장돌부를 회전밸브의 내입장홈에 끼워 회전이 용이하게 하고 회전축에 고정된 대기어는 치합된 회전밸브 단부의 소기어를 연동하여 흡입된 오일을 회전밸브와 로터의 표면이 밀착되어 고도의 기밀을 유지하는 과정이 계속 반복되면서 흡입, 토출시킬때에 마찰 저항을 받지 않게 하므로써 고장률이 없고 성능이 우수한 제품을 가격으로 생산하여 반영구적으로 사용할 수 있도록 고안한 것으로 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention communicates the rotor inlet hole in the center of the cylinder and the inner part of the rotary valve in order to solve the above closed end, so that a plurality of long protrusions protruding from the outer circumference of the rotor are inserted into the inlet groove of the rotary valve to facilitate rotation. The air gear fixed to the air is subjected to frictional resistance when suctioned and discharged while the oil suctioned by interlocking the small gear at the end of the engaged rotary valve is closely adhered to the surface of the rotary valve and the rotor to maintain high airtightness. It is designed to be used semi-permanently by producing a product having no failure rate and excellent performance at a price to be described in detail by the accompanying drawings as follows.
시린더(1)에 커버(2)와 외체(3) (3')가 결합하여서 된것에 있어서, 시린더의 중앙 로터내입공(4)의 적정위치에 회전밸브내입부(5)(6)(7)(8)를 연통되게 하고 로터내입공으로는 둘레에 등간격으로 다수개의 장돌부(9)(9')(9)(9')‥를 돌설한 로터(10)에 회전축(11)을 끼워 단부는 대기어(12)를 고정하며 회전밸브내입부에는 양측에 내입장홈(13)(13')이 요설되고 균압공(14)(14')이 연통된 회전밸브(15)(16)(17)(18)의 상단 소기어(19)를 각각 대기어에 치합시키되 내입장홈으로는 장돌부가 유삽되게 하여서 된 것이다.In the case where the cover 2 and the outer body 3 and 3 'are coupled to the cylinder 1, the rotary valve inner part 5 and 6 at the proper position of the center rotor inlet 4 of the cylinder. (7) Rotating shaft (11) to the rotor (10) in communication with each other and a plurality of long protrusions (9) (9 ') (9') (9 '). The end portion secures the air gear 12, and the rotary valve inner and inner grooves 13 and 13 'are provided on both sides, and the equalizing holes 14 and 14' communicate with the rotary valve 15 ( 16) (17) (18) is fitted with the upper small gears 19 to the air gears, respectively, so that the ridges are inserted into the internal entrance grooves.
미설명 부호 20은 오일유통공, 21은 기어내입요부, 22는 유압호스 연결구, 23은 볼트, 24는 볼트공, 25는 패킹을 표시한다.Reference numeral 20 denotes an oil distribution hole, 21 gear internal recess, 22 hydraulic hose connector, 23 bolt, 24 bolt hole and 25 packing.
이와 같이 된 본 고안은 시린더(1)의 중앙 로터내입공(4)에 로터(10)를 끼우고 회전밸브내입구(5)(6)(7)(8)에 유착된 회전밸브(15)(16)(17)(18)의 내입장홈(13)(13')에는 로터(10)의 장돌부(9)(9')(9)(9')‥를 내입하고 회전밸브(15)(16)(17)(18) 단부의 소기어(19)는 회전축(11)의 대기어(12)에 치합시켜 커버(2)를 시린더(1)와 외체(3)(3')는 양측에 볼트로 고정밀폐한 상태에서 외부 원동기(도시하지 않았음)의 회전력이 회전축(11)에 전달되면 대기어(12)가 회전하면서 소기어(19)를 연동하여 회전밸브(15)(16)(17)(18)를 회전함과 동시에 로터(10)가 회전하면서 흡입측으로 유체가 흡입되며 돌설된 장돌부(9)는 회전밸브(16)의 내입장홈(13)과 장돌부(9)는 회전밸브(18)의 내입장홈(13)에서 빠져나와 회전밸브(16)(18)와 로터(10)의 표면이 (a)부분과 같이 밀착되어 기밀을 유지할 때에 로터(10)의 장돌부 (9')는 회전밸브(15)의 내입장홈(13')과 장돌부(9')는 회전밸브(17)의 내입장홈(13')에 내입되는 작용이 순차로 계속 반복될 때에 화살표 (가)방향으로 유체가 흡입되면서 화살표 (나)방향으로는 유체가 토출이 되는 것이며, 회전방향이 바뀌면 흡입 토출방향만 바뀌게 되는 것이다.The present invention thus achieved is a rotary valve (15) fitted with a rotor (10) in the center rotor inlet (4) of the cylinder (1) and adhered to the rotary valve inlets (5) (6) (7) (8). Into the grooves 13 and 13 'of the 16, 17 and 18, the ridges 9, 9', 9 and 9 'of the rotor 10 are inserted. 15) (16) (17) (18) end gears (19) engage the standby gear (12) of the rotating shaft (11) to cover the cover (2) with the cylinder (1) and the outer body (3) (3 '). ) Is rotated by the small gear 19 while rotating the standby gear 12 when the rotational force of the external prime mover (not shown) is transmitted to the rotating shaft 11 in a state where the bolts are tightly sealed on both sides. (16) (17) (18) As the rotor (10) rotates and the fluid is sucked to the suction side, the protruding ridge (9) is the inboard groove (13) and the ridge of the rotary valve (16). The rotor (10) exits from the inlet groove (13) of the rotary valve (18) and the rotor valve (10) when the surface of the rotor (10) and the rotor (10) are in close contact with each other to maintain airtightness. )chairman The protrusion 9 'is inserted into the inlet groove 13' of the rotary valve 15 and the long protrusion 9 'is inserted into the inlet groove 13' of the rotary valve 17 in sequence. When the fluid is sucked in the direction of arrow (A), the fluid is discharged in the direction of arrow (B). If the rotation direction is changed, only the suction discharge direction is changed.
회전밸브(15)(16)(17)(18)의 양측 내입장홈(13)(13')은 로터(10)가 회전시에 등간격으로 돌설된 다수개의 장돌부(9)(9')(9)(9')‥를 내입시켜 원활하게 통과시켜 주게 되며 균압공(14) (14')은 가해지는 압력을 타측으로 전달하여 측압을 받지않게 하므로써 회전밸브(15)(16)(17)(18)가 회전할 때에 시린더(1) 벽에는 마찰하지 않고 윤활되어 마모를 방지하면서 고속회전하는 것이다.Both inner grooves 13 and 13 'of the rotary valves 15, 16, 17 and 18 are formed with a plurality of long protrusions 9 and 9' protruding at equal intervals when the rotor 10 rotates. (9) (9 ') ‥ inserts smoothly and the equalization hole (14) (14') transmits the applied pressure to the other side so as not to receive the side pressure, so that the rotary valve (15) (16) ( When the rotor 18 rotates, the cylinder 1 is lubricated without friction, and rotates at high speed while preventing wear.
이와 같은 본 고안은 산업기계가 점차 자동화되면서 필연적으로 수요가 급증한 유압펌프의 구조를 간단히 개선하므로써 생산단가를 저하시키고 사용시에는 마찰 저항이 없으며, 성능이 우수한 제품을 대량생산하여 고장률이 없이 반영구적으로 사용할 수 있는 효과가 있다.This design reduces the production cost by simply improving the structure of the hydraulic pump, which is inevitably increased in demand as industrial machinery is gradually automated, and there is no frictional resistance when using it. It can be effective.
