Abstract
The utility model relates to a motor bearing component structure special for a compressor, specifically to a transmission shaft for locking and supporting a compressor, having a support function. The structure mainly comprises a rotating shaft, a bearing outer cover, a deep groove ball bearing, an end cover and a bearing inner cover. The utility model is characterized in that the bearing inner cover and the deep groove ball bearing are sequentially equipped on the rotating shaft, the end cover is fixed on a stand by bolts, the bearing outer cover is fixed on the end cover by bolts, and then the bearing is locked. The structure is simple, compact and reasonable. When a motor operates, the inner steel ring of the bearing is interference fitted with a rotor, and tightly sleeved on the rotating shaft, the outer steel ring of the bearing is locked by the bearing inner and outer covers, therefore the bearing does not moves axially, the shaft extension end bearing of a compressor is locked, thus not affecting the stability of the auxiliary products of the compressor.
Description
Technical field
The utility model relates to a kind of compressor motor special bearing assembly structure, specifically is used to lock the power transmission shaft of supporting compressor, play supporting role.
Background technology
Compressor is the heart of refrigerating system, and under the situation that compressor is under-supply, China also needs an amount of import every year at home.In recent years, domestic compressor producer is by technology transfer and scrap build, and quality, the output of homemade compressor all increase substantially, and equally also face a lot of problems, and the structure of bearing is exactly relatively distinct issues.In prior art, compressor motor special bearing assembly is mainly by supporting compositions such as rotating shaft, bearing exterior and interior cover, deep groove ball bearing and wavy spring sheets.The motor bearings assembly of this kind structure shaft extension end bearing does not in use have lockedly, and the shaft extension end bearing has the space of moving about; Because the shaft extension end has the wavy spring sheet, after running to the regular hour, rotating shaft produces certain heat, will expand, the shaft extension end bearing is not because by locked, the shaft extension end can play, thereby the expansive force that rotating shaft produces impels the play of shaft extension end bearing, has influence on the stability of compressor auxiliary products.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of compressor motor special bearing assembly structure, when motor moves, the interior steel ring of bearing and rotor interference fit, tightly entangled firm in rotating shaft, the bearing outer rim is locked by the bearing exterior and interior cover, thereby bearing do not have axial endplay, and compressor shaft extension end bearing is locked.
Main solution of the present utility model is achieved in that
The utility model mainly comprises rotating shaft, bearing end cover, deep groove ball bearing, end cap and internal bearing cover, feature is to be sleeved on internal bearing cover, deep groove ball bearing in the rotating shaft in proper order, again with end cap by being bolted on the support, bearing end cover is by being bolted on the end cap, and bearing locks the most at last.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; When motor moved, the interior steel ring of bearing and rotor interference fit were tightly entangled firm in rotating shaft, and the bearing outer rim is locked by the bearing exterior and interior cover, thereby bearing do not have axial endplay, and 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 the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1: comprise rotating shaft 1, bearing end cover 2, deep groove ball bearing 3, end cap 4 and internal bearing cover 5 etc.
The utility model is sleeved on internal bearing cover 5, deep groove ball bearing 3 orders in the rotating shaft 1, again with end cap 4 by being bolted on the support, bearing end cover 2 is by being bolted on the end cap 4, bearing locking the most at last.
When motor moved, the interior steel ring of bearing and rotor interference fit were tightly entangled firm in rotating shaft, and the bearing outer rim is locked by the bearing exterior and interior cover, thereby bearing does not have axial endplay.
