Description

Technical Field

[0001] The utility model relates to the technical field of oil pump motors, in particular to an oil pump motor. Background Art

[0002] As one of many types of motors, the oil pump motor is mainly used to provide power for the normal operation of the oil pump. The oil pump motor includes a motor body, a front cover and an output drive shaft. The drive shaft is connected to the oil pump through a coupling. When working, the motor drives the driving wheel in the oil pump to rotate, and the driving wheel drives the driven wheel to rotate. The oil is extracted and pumped out by using the change in the volume of the oil between the driving wheel and the driven wheel during the rotation process. The oil pump can only operate normally under the driving action of the motor. Therefore, whether the connection between the oil pump and the motor is stable directly affects the working efficiency and service life of the oil pump and the motor;

[0003] For example, the utility model patent with Chinese patent publication number CN217642945U discloses an oil pump motor, which is directly connected to an oil pump or connected to a coupling, and includes a body and a front end cover, wherein a stator, a rotor and a rotating shaft are arranged in the body, and the front end cover is connected to a detachable connecting seat, wherein the connecting seat is provided with a hollow portion, and the rotating shaft passes through the hollow portion, and the connecting seat is provided with a fixing portion, and the fixing portion is provided with a first groove, and the front end cover is fixed to the oil pump or the coupling by screws through the first groove;

[0004] For another example, the utility model patent with Chinese patent publication number CN203840134U discloses a connecting device for a motor and an oil pump, comprising a first end cover and a second end cover respectively connected to the motor and the oil pump, the first end cover and the second end cover are respectively provided with matching connecting mechanisms, an axial mounting hole for inserting the input shaft of the oil pump is provided on the output shaft of the motor, a locking device capable of fastening the output shaft of the motor and the input shaft of the oil pump is provided in the cavity between the first end cover and the second end cover, at least one first notch penetrating the wall thickness is axially provided on the outer peripheral wall of the locking device, and both ends of the first notch are fastened and connected by locking bolts; a disassembly opening for disassembling and assembling the locking device is also provided on the first end cover or the second end cover;

[0005] It was found during use of the above two prior arts that the current oil pump motor, the oil pump and the motor end cover are usually fixed and installed by the cooperation of connecting parts and bolts. The overall length of the device after installation is long, occupying a large installation space, and the installation process is relatively complicated, consuming a lot of time, reducing work efficiency, resulting in poor practicality.
