Abstract
The utility model relates to a bearing assembly structure for a compressor. The bearing assembly structure comprises a bearing and a rotating shaft, an inner ring of the bearing is sleeved on the rotating shaft, a bearing inner cover is rotatably and hermetically sleeved on the rotating shaft which is arranged on the left side of the bearing, a bearing outer cover is rotatably and hermetically sleeved on the rotating shaft which is arranged on the right side of the bearing, an end cover is sleeved on an outer ring of the bearing, the thickness of the end cover is larger than that of the outer ring of the bearing, and the bearing inner cover, the bearing outer cover and the end cover are fixed into a whole by the aid of a bolt. The motor bearing assembly structure is simple, compact and reasonable, when the motor runs, the inner ring of the bearing is in interference fit with a rotor and is firmly sleeved on the rotating shaft, the outer steel ring of the bearing is locked by the bearing inner cover and the bearing outer cover, so that the bearing cannot axially move, and a drive end bearing of the compressor is locked, so that stability of auxiliary products of the compressor cannot be affected.
Description
Technical field
The utility model relates to a kind of device that thereby shaft extension end bearing locking is shielded to compressor for the compressor motor special, especially a kind of electric moto used in compressor bearing component construction.
Background technology
Compressor is the heart of refrigerating system, and in 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 by technology transfer and scrap build, and quality, the output of domestic 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 internal external shell, deep groove ball bearing and wavy spring sheets.The motor bearings assembly of this kind structure is not in use because the shaft extension end bearing has locked, bearing has the space of moving about, after motor runs to the regular hour, rotating shaft produces 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 purpose of this utility model is to overcome the deficiencies in the prior art, thereby provides a kind of bearing axial endplay that can prevent to play the electric moto used in compressor bearing component construction of protection compressor shaft extension end bearing effect.
The technical scheme that provides according to the utility model, described electric moto used in compressor bearing component construction, comprise 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, is socketed with end cap at the outer ring body of bearing, 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 bolted one.
Be provided with the right fin of annular at the right side wall of internal bearing cover, 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.
Be provided with the left fin of annular at the left side wall of bearing end cover, 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 utility model is simple in structure, compact, rationally, when motor moves, the inner ring of bearing and rotor interference fit, tightly entangled firm in rotating shaft, the bearing outer rim is decided by the bearing internal external cover lock, 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 structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: this electric moto used in compressor bearing component construction, 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, rotary seal is set with bearing end cover 4 in the rotating shaft 2 on bearing 1 right side, outer ring body at 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 are bolted one with end cap 5.
Be provided with the right fin 6 of annular at the right side wall of internal bearing cover 3, 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.
Be provided with the left fin 7 of annular at the left side wall of bearing end cover 4, 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.
