Embodiment 1

[0039] Such as figure 1 As shown, the present invention provides a motor end cover 1, which includes:

[0040] Flange 11, and an external thread 2 is provided on the outer peripheral wall of the flange 11, and when the motor end cover is engaged with the stator assembly of the motor, a threaded connection is formed with the stator assembly through the external thread 2 .

[0041] By providing external threads on the outer peripheral wall of the flanging of the motor end cover, when the motor end cover is engaged with the stator assembly of the motor, a threaded connection is formed with the stator assembly through the external threads, which can replace the original The motor end cover and the motor are combined by pressing, which effectively solves the defects of looseness and loose fixation between the motor end cover and the stator assembly, especially the end cover that exists after the motor runs hot. The hidden danger of loosening improves product quality and reduces a...

Embodiment 2

[0056] Such as Figure 2-3 As shown, the present invention also provides a stator assembly 4 having a second axis, comprising:

[0057] Stator 41;

[0058] The plastic sealing part 42 is fixedly arranged on the outer periphery of the stator 41;

[0059] The connecting ring 43 is fixedly arranged on the inner peripheral side of the plastic sealing part 42; the inner peripheral wall of the connecting ring is provided with an internal thread 5, and the stator assembly is connected with the motor end through the internal thread when the stator assembly is engaged with the motor end cover. The cap forms a threaded connection.

[0060] By providing a connecting ring on the stator assembly, and internal threads are provided on the inner peripheral wall of the connecting ring, when the stator assembly is engaged with the motor end cover, the internal thread forms a threaded connection with the motor end cover, which can replace the original The motor end cover and the motor are com...

Embodiment 3

[0075] Such as image 3 , the present invention also provides a motor, which includes the aforementioned motor end cover 1 and the aforementioned stator assembly 4, and the connection between the motor end cover 1 and the stator assembly 4 is through the external thread 2 on the flange 11 and the The internal thread 5 on the connecting ring 43 is threaded. By providing an external thread on the outer peripheral wall of the flanging of the motor end cover, when the motor end cover is engaged with the stator assembly of the motor, the external thread forms a threaded connection with the stator assembly, and, by A connecting ring is arranged on the stator assembly, and an internal thread is provided on the inner peripheral wall of the connecting ring. When the stator assembly is engaged with the motor end cover, the internal thread forms a threaded connection with the motor end cover, which can replace the original motor The end cover and the motor are combined by pressing, whic...

Abstract

The invention provides a motor end cover, a stator assembly and a motor. The motor end cover (1) comprises a flange (11), an external thread (2) is arranged on an outer peripheral wall of the flange (11), and the motor end cover is in threaded connection with the stator assembly through the external thread (2) when the motor end cover and the stator assembly of the motor are connected. Through themotor end cover, the stator assembly and the motor, compared with the prior art, a mode of pressing a motor end cover and a motor to combine in the past can be substituted, defects of looseness between the motor end cover and the stator assembly and the unfirm fixation are effectively solved, especially a hidden danger of end cover looseness of a back end cover after the motor runs and generatesheats is solved, the product quality is improved, after-sales problems are reduced, a hidden danger of axial looseness during a motor damping ring transportation process is eliminated, the tightness of a damping ring and the end cover is improved, and the safety performance of the motor is improved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor end cover, a stator assembly and a motor. Background technique [0002] At present, the combination method of the end cover of the traditional plastic-sealed motor and the motor is press-fitting, and the fixing method of it and the plastic-sealed stator is through the single-sided interference fit between the inner surface of the stator and the outer surface of the end cover. Since the thermal expansion coefficient of the end cover is smaller than that of the plastic package Due to the thermal expansion coefficient of the material, the interference decreases after the motor runs and heats up, so there is a potential for the end cover to loosen. At the same time, the coaxiality of the end cover bearing chamber and the inner circle of the stator is relatively poor under this fixing method, which is likely to cause motor noise. It can be seen that there are many d...
