Abstract

The invention discloses a disc type electronic oil pump which comprises a stator assembly, a rotor assembly and a pump assembly. The stator assembly comprises an end cover, a stator shell and a statorassembly located in the stator shell. The rotor assembly comprises a rotor shell and a rotor assembly located in the rotor shell. The pump assembly comprises a pump cover and a pump assembly locatedin the pump cover. The rotor assembly includes a rotor; a rotating shaft, a plane bearing, a shaft sleeve and a rotor, a plane bearing sleeves one end of the rotating shaft; one end of the stator assembly facing the rotor assembly is provided with a bearing seat; the plane bearing is arranged in the bearing seat, the other end of the rotating shaft penetrates through a through hole in the surfaceof the end, facing the pump assembly, of the rotor shell and stretches into the pump cover, the other end of the rotating shaft is sleeved with the pump assembly and a shaft sleeve, the shaft sleeve is arranged in the through hole of the rotor shell, and the rotor is sleeved with the rotating shaft. The plane bearing is adopted, so that high loading capacity and high rigidity can be realized in avery small space, and damage caused by large abrasion is avoided.

Description

technical field [0001] The invention relates to the technical field of electronic oil pumps, in particular to a disc type electronic oil pump. Background technique [0002] The gearbox is a very important part in a car, and the oil pump in the gearbox plays the role of lubricating, cooling and shifting, and is an indispensable key component. Electronic oil pump is getting more and more attention due to its advantages of high efficiency, compact structure and flexible control. However, the stator and rotor of the electronic oil pump in the prior art always attract each other by electromagnetic force, which may cause uneven wear, thereby making the electronic oil pump vulnerable to damage. SUMMARY OF THE INVENTION [0003] The embodiment of the present invention provides a disc-type electronic oil pump to solve the problem that the electronic oil pump in the prior art is easily damaged. [0004] An embodiment of the present invention discloses a disc-type electronic oil pu...
