Embodiment 1

[0043] This embodiment is the most preferred for implementing the present invention. Such as image 3 As shown, the motor structure of the compressor in this embodiment includes a stator 4 , a crankshaft 5 , and an upper bearing part 6 and a lower bearing part 7 sleeved on the crankshaft 5 . Such as image 3 and Figure 9-11As shown, the lower bearing part 7 includes a bearing frame 71, which includes a base 711 and a shaft extending from the periphery of the base 711 in the axial direction (that is, along the entire lower bearing part 7 and the axial direction of the crankshaft 5 it is sleeved on). Four slats 712 , the outer walls of these slats 712 match the inner wall of the stator 4 and are placed against the inner wall of the stator 4 . Wherein, the number of slats 712 can also be set to two, three, five, etc. as required, as long as they can be matched with the inner wall of the stator 4 and set against it, the number is not limited to the above four ; The lower bear...

Embodiment 2

[0054] Others are the same as those described in Embodiment 1, the difference is: as image 3 and Figure 12-13 As shown, the bearing frame 71 in this embodiment includes a base 711 and a cylindrical body 713 formed by extending the periphery of the base 711 in the axial direction. The outer wall of the cylindrical body 713 matches the inner wall of the stator 4 and leans against the inner wall of the stator 4 set up. The beneficial effects obtained in this embodiment are the same as those in Embodiment 1.

[0055] Such as Figure 12-13 As shown, four stepped surfaces 714 may be formed on the outer wall of the cylinder 713, and the stepped surfaces 714 also have the same protruding portion 715 as in the first embodiment. Wherein, the number of stepped surfaces 714 can be set as two, three, five, etc. as required, as long as it can be matched with the inner wall of the stator 4 and set against it, and its number is not limited to the above four.

Embodiment 3

[0057] Others are the same as those described in Embodiment 1 or 2, except that: Figure 14 As shown, the inner walls of the slats 712 match and rest against the outer walls of the stator 4 . The beneficial effects obtained in this embodiment are the same as those in Embodiment 1.

[0058] continue as Figure 14 As shown, the slats 712 may have the same stepped surface 714 as in Embodiment 1, which matches the groove 42 on the outer wall of the stator 4 .

Abstract

The invention discloses a motor structure of an air compressor. The motor structure includes a stator, a crankshaft, and an upper bearing part and a lower bearing part, which sleeve the crankshaft. The lower bearing part includes a bearing support which includes a base and units which are formed through axial extension from the periphery of the base, wherein the centers of the units aligns with the axis of the stator and is connected with the stator so that the center of the base aligns with the axis of the stator; and a bearing body arranged on the base in the middle. At the same time, the invention also provides a scroll compressor which includes the motor structure. Compared with the prior art, only improvements of the structure and connection of the bearing support are made and no special-purpose device is used for installing the lower bearing and only a common installation method is used so that the installation cost is reduced and the installation process is simplified and thus the assembly efficiency of the compressor can be improved significantly and the motor structure is a technology suitable for wide popularization and application.

Description

technical field [0001] The invention relates to compressor technology, in particular to a compressor motor structure and a scroll compressor including it. Background technique [0002] Compressors are widely used in various industries related to national life, and with the advancement of technology, their higher reliability has become what today's compressor users hope to obtain, and accordingly it has become a compressor designer. One of the important directions for technology research and development. [0003] In the compressors currently used, the motor is an important part, which drives the air compression mechanism of the compressor and affects the reliability of the entire compressor. Now the motor structure of the compressor is as follows: Figure 1-2 As shown, it mainly includes a rotor 21, a stator 22, a crankshaft 31, and an upper bearing 32 and a lower bearing 33 sleeved on the crankshaft 31, etc., wherein the upper bearing 32 and the lower bearing 33 are respect...
