Description:

Rexroth external gear pump of a gear meshing with each other, due to the gap between the top gear tooth surface hole and the shell is very small, Rexroth external gear pump gear pump cover and the gap is very small, thus separating the oil cavity and the oil cavity pressure, when the gear according to the method, from two aspects the action at the same time: 1) after meshing engagement with the right gear meshing and gradually withdraw, oil between the teeth by suction chamber to the oil pressure chamber, the suction chamber clearance increases, the formation of partial vacuum, the oil in the tank into the suction chamber in the role of the outside world under atmospheric pressure; 2) gear oil from the high pressure chamber into the suction chamber at the same time, the left side of the tooth meshing point gradually into the mesh to the oil squeezed out from between the teeth, pressure oil forced out. This is a process of Rexroth external gear pump gear oil and oil pressure, when the rotation of the gear pump gear pump is constant, constant pressure oil and oil.
