The rotor type oil pump is composed of a housing, an inner rotor, an outer rotor, a pump cover, etc. The inner rotor is fixed on the rotor shaft with a key or pin and driven directly or indirectly by the crankshaft gear. The eccentricity between the inner rotor and the outer rotor is e, and the inner rotor drives the outer rotor to rotate in the same direction.
Generally, the inner rotor of a rotor type oil pump has 4 or more convex teeth, and the number of concave teeth of the outer rotor is one more than the number of convex teeth of the inner rotor, so that the inner and outer rotors rotate asynchronously in the same direction.The profile shape curve of the rotor is hypocycloid.
The tooth profile of the rotor is designed so that when the rotor turns to any angle, the tooth profile lines of each tooth of the inner and outer rotors can always contact each other at points. In this way, four working cavities are formed between the inner and outer rotors. With the rotation of the rotor, the volume of these four working cavities is constantly changing. In the cavity at one side of the oil inlet passage, as the rotor disengages from the mesh, the volume gradually increases, generating vacuum, the oil is sucked in, the rotor continues to rotate, and the oil is brought to the side of the oil outlet passage. At this time, the rotor just enters the mesh, reducing the volume of this cavity, increasing the oil pressure, and the oil is squeezed out of the teeth and pressed out through the oil outlet passage. In this way, with the continuous rotation of the rotor, the oil will be constantly sucked in and pressed out.
