Abstract
The invention relates to a motor bearing assembly structure for a compressor, comprising a bearing and a rotating shaft, wherein an inner ring body of the bearing is sleeved on the rotating shaft; the rotating shaft arranged at the left side of the bearing is rotationally provided with an inner bearing cover in a sealing and sleeving way, and the rotating shaft arranged at the right side of the bearing is rotationally provided with an outer bearing cover in a sealing and sleeving way; an outer ring body of the bearing is connected with an end cover which is thicker than the outer ring body of the bearing in a sleeving way; and the inner bearing cover, the outer bearing cover and the end cover are fixed into a whole through bolts. The motor bearing assembly structure for the compressor is simple, compact and reasonable in structure; when a motor runs, the inner ring body of the bearing is in interference fit with a rotor and tightly sleeved on the rotating shaft, and an outer steel ring of the bearing is locked by the inner bearing cover and the outer bearing cover, so that the bearing has no axial drifting; and the bearing at the shaft extension end of the compressor is locked, so that the stability of a combining product of the compressor cannot be influenced.
Description
Technical field
Thereby the present invention relates to a kind of compressor motor special shields the locking of shaft extension end bearing to compressor device, especially a kind of electric moto used in compressor bearing assembly structure of being used for.
Background technology
Compressor is the heart of refrigerating system, and under the situation that compressor is under-supply at home, China also needs an amount of import every year.In recent years, domestic compressor producer is through technology transfer and scrap build, and quality, the output of homemade compressor all increase substantially, but also faces a lot of problems simultaneously, and the structure of bearing is exactly relatively distinct issues.In prior art, compressor motor special shaft extension end bearing assembly is mainly by supporting compositions such as rotating shaft, bearing inside and outside shell, deep groove ball bearing and wavy spring sheets.The motor bearings assembly of this kind structure is not locked owing to the shaft extension end bearing in use; Bearing has the space of moving about, and after motor ran to the regular hour, rotating shaft produced certain heat; Will expand; The shaft extension end bearing will be because not by locked, the expansive force that rotating shaft produces will impel motor shaft to shaft extension end play, thereby have influence on the stability of compressor auxiliary products.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, thereby provide a kind of bearing axial endplay that can prevent to play the electric moto used in compressor bearing assembly structure of protection compressor shaft extension end bearing effect.
According to technical scheme provided by the invention, said electric moto used in compressor bearing assembly structure comprises bearing and rotating shaft; The inner ring body of bearing is enclosed within the rotating shaft; Rotary seal is set with internal bearing cover in the rotating shaft in bearing left side, and rotary seal is set with bearing end cover in the rotating shaft on bearing right side, on the outer ring body of bearing, is socketed with end cap; The thickness of end cap is greater than the thickness of bearing outer ring body, and internal bearing cover, bearing end cover and end cap are through the bolt one.
On the right side wall of internal bearing cover, be provided with the right fin of annular, right fin is coaxial setting with internal bearing cover, and the outside diameter of right fin equates with the outside diameter of bearing outer ring body.
On the left side wall of bearing end cover, be provided with the left fin of annular, left fin is coaxial setting with bearing end cover, and the outside diameter of left fin equates with the outside diameter of bearing outer ring body.
The present invention is simple, compact and reasonable for structure, when motor moves; The inner ring of bearing and rotor interference fit; Tightly entangled firm in rotating shaft, the bearing outer rim is by the locking of bearing exterior and interior cover, thereby bearing does not have axial endplay; Compressor shaft extension end bearing is locked, thereby can not have influence on the stability of compressor auxiliary products.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this electric moto used in compressor bearing assembly structure; Comprise bearing 1 and rotating shaft 2; The inner ring body of bearing 1 is enclosed within the rotating shaft 2; Rotary seal is set with internal bearing cover 3 in the rotating shaft 2 in bearing 1 left side, and rotary seal is set with bearing end cover 4 in the rotating shaft 2 on bearing 1 right side, on the outer ring body of bearing 1, is socketed with end cap 5; The thickness of end cap 5 (being the distance between end cap 5 left and right sides sidewalls) is greater than the thickness (being the distance between the bearing 1 outer ring body left and right sides sidewall) of bearing 1 outer ring body, and internal bearing cover 3, bearing end cover 4 pass through the bolt one with end cap 5.
On the right side wall of internal bearing cover 3, be provided with the right fin 6 of annular, right fin 6 is coaxial setting with internal bearing cover 3, and the outside diameter of right fin 6 equates with the outside diameter of bearing 1 outer ring body.
On the left side wall of bearing end cover 4, be provided with the left fin 7 of annular, left fin 7 is coaxial setting with bearing end cover 4, and the outside diameter of left fin 7 equates with the outside diameter of bearing 1 outer ring body.
When motor moved, the inner ring body of bearing 1 and rotating shaft 2 interference fit were tightly entangled firm in rotating shaft 2, and the outer ring body of bearing is by internal bearing cover 3 and bearing end cover 4 lockings, thereby bearing 1 does not have axial endplay.
