德國Rexroth力士樂齒輪泵全系列
Germany Rexroth hydraulic gear pump is a hydraulic system is widely used, it is generally made of a metering pump, according to a different structure. Divided into external gear pump pyridine ring gear and the ring gear pump mining, external gear pumps are most widely used. Gear pump is mainly composed of a pair of gears, housings, pump cover, shaft and bearing and seal cover and other components. In the pump body has a pair of external gear, the gear end faces sealed by the cover plate, so each alveolar pump, cover and gears to form a plurality of sealed chamber, turn left and right tooth contact line separating two sealed chambers formed suck pressure oil chamber. When the gear rotates in the direction shown, teeth suction chamber (right side) within the continuous disengaged, so that the seal and increasing the volume of a certain vacuum, at atmospheric pressure from the tank sucked into the oil, with the rotating gears, oil was brought within the alveolar pressure oil chamber (the left) Shin pressure oil chamber into the continuous engagement of the teeth, so that the seal decreasing volume, the oil is pressed out. With spinning gear, gear pumps for continuous suction and discharge of oil. Three of German Rexroth gear pump is mainly leaks, trapping and radial hydraulic pressure imbalance, these three issues affect the gear pump performance and service life, so all kinds of gear pumps have taken different structural measures to solve these problems.

德國力士樂齒輪泵工作時，因為排油壓力大于吸油壓力，從排油腔到吸油腔，齒輪頂圓圓周徑向壓力是線性階梯變化的，從而產生徑向力不平衡。
通過分析可知，必須在結構采取一定的措施，減少齒輪泵的徑向合力，從而延長齒輪泵的壽命。采取的措施如下。
(1)縮小排油口尺寸，使高壓油作用在齒輪上的面積縮小，從而減小作用在齒輪上的徑向力。
(2)適當增大徑向間隙.增大齒頂圓與泵體內孔的問隙，以平衡徑向力不平衡。但增大徑向間隙會使泄漏增加容積效率降低，因此髙壓泵不宜釆用此方法。
