Problems solved by technology

[0004] It can be seen that the DC motor assembly has many parts and assembly processes, and the efficiency is not high; the thickness of the assembled motor assembly is relatively thick, which will bring inconvenience to the assembly of parts and the design of the whole machine. Taking the application in a refrigerator as an example, the fan The rotation drives the circulation of cold air and the flow of cold air between the rooms. The thicker motor components will affect the volume of the refrigerator, which is not conducive to the increase of the volume of the refrigerator.

Abstract

The invention discloses a DC motor and an assembling method thereof. On the basis of an existing motor working principle, a new motor component assembling mode is provided, a motor housing and a mounting support form a component having an integrated structure in a hot-press manner, the motor housing and the mounting support do not need to be connected by means of a fixing piece and screws, and the mounting support also does not need to be provided with connecting holes for fits by scrrews, so the structure is optimized, and parts and assembling working procedure are reduced. The invention further discloses a refreigerator using the DC motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a refrigerator, a DC motor and an assembly method thereof. Background technique [0002] The DC motor assembly consists of fan blades 11 , screws 12 , fixing pieces 13 , DC motor 14 and mounting bracket 15 . Wherein, DC motor 14 is made up of motor front end cover 141, rotor 142, stator 143, motor housing 144, motor rear end cover 145 and drive plate 146, and its structure can refer to figure 1 shown. [0003] At present, the motor and the mounting bracket are produced separately. In the assembly process, the motor is first assembled with the fixing part. Through the screw hole on the fixing part, the fixing part, the motor and the mounting bracket are fixed tightly with screws, and finally the fan blade is assembled on the motor shaft. , forming a motor assembly. [0004] It can be seen that the DC motor assembly has many parts and assembly processes, and the efficiency is not...
