Description

기어펌프{GEAR PUMP}Gear Pump {GEAR PUMP}

본 고안은 각종 유체나 슬러지 등을 펌핑하는 기어펌프에 관한 것으로서, 상세하게는 마모에 의한 관련부품의 수명단축 및 누유를 방지해 줄 수 있도록 한 것이다.The present invention relates to a gear pump for pumping various fluids or sludges, and more particularly, to prevent shortening of life and leakage of related parts due to wear.

각종 유체나 슬러지 등을 펌핑하는 기어펌프는 좌우에 커버를 갖는 하우징의 펌핑실 내에 한쌍의 맞물림기어가 베어링을 통하여 회전가능케 연결설치되고 또 어느 한 기어가 갖는 축봉은 하우징 외측으로 돌출되게 하여 모터와 연결해 주도록 구성되는데, 이때 기어의 양측면과 하우징 양측에 갖는 커버 사이에는 틈을 없애주어야만 강한 흡입력이 작용하게 되고 또 기어를 회전가능케 연결지지하는 베어링은 유체의 유입을 방지해 주어야만 수명을 보장해 줄 수가 있게 된다.Gear pumps for pumping various fluids and sludges are installed in a pumping chamber of a housing having a cover to the left and right so as to be rotatably connected through a bearing, and the shaft of one of the gears protrudes out of the housing. In this case, the gap between the two sides of the gear and the cover on both sides of the housing must be eliminated so that a strong suction force can be applied, and the bearing supporting the rotatably connected gear can ensure the life only when the fluid is prevented from entering. do.

도 1 및 도 2는 이제껏 이용되어 오고 있는 기어펌프를 도시한 것으로서, 종래에 기어펌프는 하우징(100)의 양측 커버(102)가 맞물림기어(104)의 기어부(106) 측면과 긴밀히 접촉하도록 하여 하우징 내에서 맞물림기어(104)를 사이에 두고 강한 흡입력과 강한 토출압이 작용하도록 하고, 기어부(106)와 베어링(108) 사이에는 내,외측 메탈링(112)(114)으로 구성되는 오일씰(110)을 갖도록 하여 외측메탈 링(114)은 베어링(108)의 외측케이스와 긴밀히 접촉되어 고정되게 하고 또 내측메탈링(112)은 기어부(106)의 측면과 긴밀히 접촉되어 함께 회전하면서 베어링(108)쪽으로의 누유를 방지해 주도록 구성된다.1 and 2 show a gear pump that has been used so far, and the gear pump is conventionally in such a way that both cover 102 of the housing 100 is in intimate contact with the side of the gear portion 106 of the engagement gear 104. In this case, a strong suction force and a strong discharge pressure are applied to the engagement gear 104 in the housing, and the inner and outer metal rings 112 and 114 are formed between the gear part 106 and the bearing 108. The outer metal ring 114 is in close contact with the outer case of the bearing 108 to be fixed by having the oil seal 110 and the inner metal ring 112 is in intimate contact with the side surface of the gear part 106 to rotate together. It is configured to prevent leakage to the bearing 108.

따라서 이러한 구조의 기어펌프는 기어(104)의 측면과 직접적으로 접촉하는 커버(102)는 쉽게 마모되므로 사용할수록 성능저하를 가져오게 되고 또 심한 마모시에는 커버(102)를 교체해 주어야 하므로 마모에 의한 부품의 교체비용이 과다소요되며, 오일씰(110)을 구성하는 내,외측메탈링(112)(114)은 단순히 서로간에 맞물림이 이루어지도록 함으로서, 펌핑시 심한 마찰소음을 발생시키게 됨은 물론 내,외측메탈링(112)(114) 사이에는 유격이 발생될 수 밖에 없어 누유에 의한 베어링(108)의 손상으로 기어(104)의 회전이 원활하게 이루어질 수가 없을 뿐 아니라 베어링(108)의 수명단축에 따른 잦은 교체로 유지관리비용이 추가소요되는 등의 많은 문제점들이 있는 것이다.Therefore, the gear pump of this structure is the wear of the cover 102 in direct contact with the side of the gear 104 is easy to wear, so the performance is reduced as you use it, and in case of severe wear, the cover 102 must be replaced because of wear Parts replacement cost is excessively required, the inner and outer metal ring 112, 114 constituting the oil seal 110 is simply made to be engaged with each other, thereby generating severe friction noise when pumping, of course, the inner and outer Since the play between the metal rings 112 and 114 can not only occur, the gear 108 may not be rotated smoothly due to the damage of the bearing 108 due to leakage of oil, and the life span of the bearing 108 may be reduced. There are many problems such as frequent replacement and additional maintenance costs.

본 고안은 마모에 의한 부품의 교체비용을 줄여 줄 수가 있고 또 오일씰로 인한 소음발생을 방지해 줄 수가 있으며, 특히 누유방지로 베어링의 사용수명을 보장해 줄 수가 있는 기어펌프를 제공하는데 그 목적이 있다.The present invention can reduce the replacement cost of parts due to wear and to prevent the noise caused by the oil seal, in particular to provide a gear pump that can guarantee the service life of the bearing by preventing leakage. .

본 고안의 목적은 하우징 양측에 갖는 커버가 소모성 밀폐판을 통하여 기어의 기어부 측면과 접촉하도록 하고, 기어부와 베어링 사이에 갖는 오일씰은 기어축과는 물론 기어부와도 탄성을 갖고 접촉하는 오일링의 탄성으로 베어링의 외측케이스와 긴밀한 접촉이 이루어져 누유가 방지되게 하며, 커버측으로 유입된 유체는 커버 하부에 갖는 집유실을 통하여 하우징의 유입실측으로 유입되도록 한 기어펌프에 의해 달성된다.The purpose of the present invention is to make the cover on both sides of the housing contact the gear part side of the gear through the consumable sealing plate, and the oil seal between the gear part and the bearing is elastically contacted with the gear part as well as the gear part. The elasticity of the ring makes intimate contact with the outer case of the bearing to prevent leakage of oil, and the fluid introduced into the cover side is achieved by a gear pump which is introduced into the inlet chamber side of the housing through the collecting chamber under the cover.

본 고안은 하우징(14) 양측에 갖는 커버(36)(38)는 교체가능케 결합되는 소모성 밀폐판(24)(26)을 통하여 기어부(40)의 측면과 접촉하게 되므로 오랜 사용에 의한 마모시 밀폐판(24)(26)의 교체만으로 기밀을 유지해 줄 수가 있어 마모에 따른 부품의 교체비용을 절감할 수가 있게 된다.According to the present invention, the cover 36 and 38 having both sides of the housing 14 come into contact with the side surface of the gear part 40 through the consumable sealing plates 24 and 26 that are interchangeably coupled, and thus, when worn by long use. It is possible to keep the airtight only by replacing the sealing plates 24 and 26, thereby reducing the cost of replacing parts due to wear.

또한 오일씰(28)(30)은 관체부(42)가 갖는 오일링(44)(46)에 의해 기어축(20)(22)과의 사이에서 누유가 방지되게 하면서 그 내측 오일링(44)은 관체부(42)로부터 돌출하여 기어부(40)의 측면과 탄성을 갖고 접촉하도록 함으로서, 오 일씰(28)(30)이 오일링(44)의 탄성에 의해 외측으로 밀려나면서 그 접촉테(48)가 베어링(32)(34)의 외측케이스가 갖는 측면과 긴밀히 접촉하여 누유를 방지해 주게 되므로, 펌핑작동시 오일씰(28)(30)로 인한 소음발생우려가 없고 또 누유에 의한 베어링(32)(34)의 작동불량 및 수명단축을 방지해 줄 수가 있게 된다.In addition, the oil seals 28 and 30 may be prevented from leaking between the gear shafts 20 and 22 by the oil rings 44 and 46 of the tubular portion 42. By protruding from the tubular portion 42 and elastically in contact with the side of the gear portion 40, the oil seal 28, 30 is pushed outward by the elasticity of the oil ring 44, the contact frame ( Since 48 is in close contact with the side of the outer case of the bearings 32 and 34 to prevent leakage, there is no fear of noise caused by the oil seals 28 and 30 during the pumping operation. 32) It is possible to prevent the malfunction and shorten the life of 34.

더 나아가 혹여 소모성 밀폐판(24)(26)의 마모로 인하여 누유가 발생되어 커버(36)(38)와 오일씰(28)(30) 사이로 유체가 유출되더라도 유출된 유체는 자중에 의해 커버(36)(38)의 내측 하부에 갖는 집유실(54)에 집유되고 집유된 유체는 유입관(10) 내에서 작용하는 흡입력에 의해 곧바로 유입관(10) 내부로 유입되므로 부품의 마모로 인한 유격발생시에도 누유를 방지해 줄 수가 있게 되는 등의 효과가 있는 것이다.Furthermore, even if leakage occurs due to abrasion of the consumable sealing plates 24 and 26 and the fluid leaks between the covers 36 and 38 and the oil seals 28 and 30, the leaked fluid is covered by its own weight. The fluid collected and collected in the collection chamber 54 of the lower part of the inner part 38 is directly introduced into the inlet pipe 10 by the suction force acting in the inlet pipe 10. Edo will be able to prevent leakage, etc. is effective.

Oil is prevented from contacting the inner oil ring 44 to partially protrude outward from the tubular portion so as to elastically contact the side surface of the gear portion 40 of the meshing gears 16 and 18. The elasticity of the ring 44 is such that the contact frame 48 is in intimate contact with the outer case of the bearings 32 and 34.

그리고 밀폐판(24)(26)과 오일씰(28)(30) 및 베어링(32)(34)등을 커버하는 커버(36)(38)는 각각 밀폐판(24)(26)을 결합고정하는 좌우결합홈(50)(52) 내측 하부에는 좌우결합홈을 연통하고 또 하우징(14)의 유입실(14a)쪽으로 노출되는 집유실(54)이 형성되게 하고, 결합홈의 내면에는 기밀유지를 위한 밀폐링(56)(58)이 형성되게 하며, 기어축(20)(21)이 관통하는 통공(60)(62)의 외측에는 베어링 케이스가 결합고정되게 한다.The covers 36 and 38 covering the sealing plates 24 and 26 and the oil seals 28 and 30 and the bearings 32 and 34 are respectively fixed to the sealing plates 24 and 26. In the lower portion of the left and right coupling grooves 50 and 52, a collection chamber 54 communicating with the left and right coupling grooves and exposed toward the inflow chamber 14a of the housing 14 is formed, and an airtightness is maintained on the inner surface of the coupling groove. The sealing rings 56 and 58 are formed, and the bearing case is coupled to the outside of the through holes 60 and 62 through which the gear shafts 20 and 21 pass.

본 발명은 도 3에서와 같이 조립시 하우징(14)의 양측에 결합고정되는 커버(36)(38)는 결합홈(50)(52)에 결합되는 밀폐판(24)(26)을 통하여 맞물림기 어(16)(18)의 기어부(40) 측면과 긴밀한 접촉이 이루어지고 또 커버(36)(38)와 밀폐판(24)(26) 사이에는 밀폐링(56)(58)이 형성되므로 하우징(14) 내에서 강한 흡입력이 작용할 수 있도록 하게 되며, 오랜 사용에 의한 마모시 소모성 밀폐판(24)(26)의 교체만으로 정상작동이 이루어지게 된다.In the present invention, the cover 36 and 38 coupled to both sides of the housing 14 when assembled as shown in FIG. 3 are engaged through the sealing plates 24 and 26 coupled to the coupling grooves 50 and 52.
