Abstract

The invention discloses a novel even oil-supplying rotor type oil pump. The novel even oil-supplying rotor oil pump comprises an oil pump main body, an upper cover body, a lower cover body, an oil feeding pipeline, a machine oil inlet, an oil pump body, a working cavity, a rotary shaft, an oil feeding cavity, an oil discharging cavity, an oil discharging pipeline, an oil feeding outlet, an inner rotor, an outer rotor, a rotor cavity, a pipeline protective sleeve and a fixing bolt; the oil feeding pipeline is formed in the left side of the oil pump main body, the oil pump body is installed on the right side of the oil feeding pipeline, and the working cavity is formed in the oil pump body; the rotary shaft is installed in the working cavity, the oil feeding cavity and the oil discharging cavity are formed in the working cavity, and the oil discharging pipeline is formed in the right side of the oil pump body; and the right side of the oil discharging pipeline is connected with the oil feeding outlet, and the inner rotor and the outer rotor are installed in the oil pump body. The novel rotor type oil pump is compact in structure, the boundary dimension is small, the weight is small, the oil-absorbing vacuum degree is large, the oil pumping quantity is large, the oil-supplying homogeneity is good, cost is low, and the novel rotor type oil pump can be widely applied to small and medium engines.

Description

technical field [0001] The invention relates to the field of oil pumps, in particular to a novel rotor type oil pump with uniform oil supply. Background technique [0002] The function of the oil pump is to increase the oil to a certain pressure and force it to the moving surface of the engine parts. It is a very important part in the lubrication system of the diesel engine. At present, the engine oil pump mainly includes gear type and rotor type. The type oil pump is composed of a shell, an inner rotor, an outer rotor, a pump cover, etc. Each tooth profile of the inner and outer rotors can form a point contact, and form a closed cavity when rotating. At the same time, with the rotation of the rotor, these sealed cavities The volume of the engine is constantly changing. In the cavity on the side of the oil inlet, because the rotor is disengaged, the volume cavity increases, a vacuum is generated, the oil is sucked in, the rotor continues to rotate, and the oil is taken to th...
