Abstract
The utility model relates to an end cover assembly for an electric machine, which comprises a bearing indoor stretching end cover (1) and an outer stretching machine body supporting seat (2), wherein the bearing indoor stretching end cover (1) is provided with a rotation shaft stretching hole (12) and a bearing chamber (11) which is stretched inward, the outer stretching machine body supporting seat (2) is provided with a supporting cavity body (21) which is stretched outward, the outer stretching machine body supporting seat is positioned at the outer side of the stretching end cover (1) in the bearing chamber, and the outer stretching machine body supporting seat is fixed on the outer wall (13) of the bearing indoor stretching end cover (1) through a connecting piece (3). Since the utility model adopts a structure that the bearing indoor stretching end cover is riveted with the outer stretching machine body supporting seat, and thus, the utility model not only can shorten the distance of two bearings of the electric machine and can reduce the vibration and the noise of the electric machine, but also can carry out installation on a load installation bracket through the outer stretching machine body supporting seat. The utility model is a low-noise end cap assembly of an iron case electric machine for an air conditioner, and the end cap assembly has artful design, simple structure, easy installation and good performance.
Description
1, technical field:
The utility model is a kind of end-cap assembly that is used for motor, and the low noise end-cap assembly of the used iron-clad motor of particularly a kind of air conditioner belongs to the renovation technique of electric motor end cap.
2, background technology:
The end cap bearing chamber of the existing used motor of air conditioner all adopts the structure of in-draw or out-draw, the end cover structure compactness of in-draw bearing chamber, distance between bearings are little, can effectively reduce motor noise and vibration, stretch the requirement that the motor shaft cushion cap is installed with twin shaft but can not satisfy window air conditioner, coiled air-conditioning internal machine, the interior machine of big split etc.; The end cap of out-draw bearing chamber can solve window air conditioner, coiled air-conditioning internal machine, the interior machine of big split etc. and stretch the requirement that the motor shaft cushion cap is installed with twin shaft, but has defectives such as the motor bearings sound is big, vibration is big.
3, summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of and not only can reduce the motor bearings sound, reduces motor oscillating, and can satisfy machine in window air conditioner, coiled air-conditioning internal machine, the big split etc. is stretched motor shaft cushion cap installation requirement with twin shaft the end-cap assembly that is used for motor.The utility model design is ingenious, simple in structure, function admirable.
Structural representation of the present utility model as shown in drawings, include bearing chamber in-draw end cap (1), out-draw body bearing (2), bearing chamber in-draw end cap (1) is made the bearing chamber (11) and the rotating shaft of oriented in-draw and is stretched out hole (12), out-draw body bearing (2) is made the support cavity (21) of oriented out-draw, it places the outside of bearing chamber in-draw end cap (1), and is fixed on by connector (3) on the lateral wall (13) of bearing chamber in-draw end cap (1).
Above-mentioned bearing chamber in-draw end cap (1) also includes fitting surface (14), stator core fixed cylinder (15), and fitting surface (14) surrounds the hollow cavity (16) that communicates with bearing chamber (11) with stator core fixed cylinder (15).
Above-mentioned connector (3) is a rivet, or is threaded connector.
Above-mentioned bearing chamber in-draw end cap (1) is the whole sheet metal stamping parts of bearing chamber (11) to in-draw.
Above-mentioned out-draw body bearing (2) is for supporting the whole sheet metal stamping parts that cavity (21) outwards stretches.
The utility model is owing to adopt the structure of bearing chamber in-draw end cap and out-draw body bearing riveted, therefore, it not only can shorten the spacing of motor two bearings, reduces vibration, the noise of motor, can install by the installing rack of out-draw body bearing and load again.The utility model is that a kind of design is ingenious, simple in structure, easy for installation, the end-cap assembly that is used for motor of function admirable.
4, description of drawings:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
5, embodiment:
