Automobile Oil Pump Gears

Product Introduction:

The oil pump casing has an oil inlet and an oil outlet. A driving gear and a driven gear are installed in the oil pump casing. There is a small gap between the gear and the inner wall of the casing. The other working principle is as a gear. When rotating clockwise, the volume of the oil inlet cavity increases due to the gear teeth moving away from the toothing direction, resulting in a certain degree of vacuum. The lubricating oil is filled from the oil inlet and filled into the oil cavity, and the rotating gear will intersect the teeth. The lubricating oil is brought to the oil cavity. As the gear teeth enter the toothing, the volume of the oil outlet cavity is reduced and the oil pressure rises. The lubricating oil is delivered to the engine oil passage through the oil outlet.

The driving gear of the pump bai rotates, the gear in the suction chamber is disengaged, and the gear teeth exit between the teeth, which increases the sealing volume and forms a partial vacuum. The oil in the oil tank passes through the suction pipeline and the suction chamber under the action of the external atmospheric pressure. Enter between the teeth. As the gear rotates, the oil sucked between the teeth is taken to the other side and enters the oil pressure chamber. This is when the gears enter into meshing, which gradually reduces the sealing performance, and the oil in the gears is squeezed out, forming the gear oil pressing process. When the gear meshes, the tooth-direction contact line separates the oil suction chamber and the pressure oil chamber, and plays the role of oil distribution. When the driving gear of the gear pump is continuously rotated by the motor, the gear is disengaged from the meshing side. As the sealing volume becomes larger, the oil is continuously sucked from the oil tank, and the gear teeth enter the meshing side. Oil, forming a continuous cycle.
